“Mind, Prana , sex-energy sex-energy (Virya) , , and the the subtle subtle desires desires of the the subconsciou subconsciouss (Vasanas) are interdependent. Control of any one of these leads to the control of all others. In other words, when one has attained mastery of Prana, one automatically acquires control of mind, sex energy, and subtle desires. “Pranayama is the control of the vital force through the regulation of breath. It therefore leads to Vasanayama. In other words, control of the vital force leads to the control of the subtle desires of  the subconscious. When the subconscious mind is freed from worldly Vasanas or complexes, one attains the immense powers of the Spirit.”

 —Swamii Jyotirm  —Swam Jyotirmaya ayanand nandaa “The peptide-respiratory link is well documented: Virtually any peptide found anywhere else can be found in the respiratory center. This peptide substrate may provide the scientific rationale for  the powerful healing effects of consciously controlled breath patterns. Mind doesn’t dominate body; it becomes body. Body and mind are one . . . At this molecular level there really [is] no distinction between the mind and the body.” Candace Pert, Molecules of Emotion  — Candace  Normal respiratio respirationn rates for an adult person person at at rest range range from from 12 to 20 breaths per minute, minute, and  and  on average 6 to 8 liters of air are inhaled per minute .

“Vanita Panapalia (32), who was admitted to Masina Hospital, Byculla, with 75 per cent  burns and a very small chance of survival, survival, has finally recovered after after almost 100 days of  treatment. “Her hands still bandaged, she is now able to walk and eat on her own. With a radiant smile, this resident of Akola, praises the doctors and nurses who helped her recover. “But apart from the treatment at the hospital, Vanita has an unusual do-it-yourself cure up her sleeve. ‘I would perform Pranayama as often as I could manage. It helped me build my willpower.’ “Vinod Panapalia, her husband says, ‘When we had rushed her to hospital after using  blankets to douse the flames on her, the doctors doctors had said Vanita had 75 per cent burns and no chance of survival.’ “But Vanita did not lose hope. ‘I have faith in yoga. Though I could not move to perform the asanas, I would feel strong every time I did Pranayama. Never for a moment did I think that I would not survive,’ she said. “Zubin Zarthoshtimanesh, an Iyengar Yoga teacher, believes that yoga could have been an important tool in her recovery. “‘Pranayama is the harnessing of energy through the breath. It has a direct impact on your  mind, psyche and your will power,’ he says. “Doctors say that survival is difficult for someone with 50 per cent and above burns. ‘Only athletes and people with a good constitution can survive such burns,’ says Dr  Milind Ghare from Wockhardt Hospital, Mulund. “Vanita was admitted to Masani Hospital after she sustained burns when her synthetic sari caught fire on December 31.” Respiratory changes during the practice of the technique of Transcendental Meditation. Lancet , 1970, no. 7651:833-834.

Abstract: Reaction time (RT) is an index of the processing ability of [the] central nervous system and a simple means of determining sensory-motor performance. It has been reported that yoga training improves human performance including central neural  processing. Earlier studies from our laboratories have shown that yoga training produces a significant decrease in visual reaction time (VRT) and auditory reaction time (ART). The  present work was planned to determine if mukh bhastrika (a yogic technique in which  breath is actively blasted out in “whooshes” following a deep inspiration) has any effect on central neural processing by studying its effect on RT. 22 healthy schoolboys who were  practicing yoga for the past three months were recruited for the present study. VRT and ART were recorded before and after nine rounds of much bhastrika. Mukh bhastrika  produced a significant (P<0.01) decrease in VRT as well as ART. A decrease in RT indicates an improved sensory-motor performance and enhanced processing ability of  central nervous system. This may be due to greater arousal, faster rate of information  processing, improved concentration and/or an ability to ignore extraneous stimuli. This is of applied value in situations requiring faster reactivity such as sports, machine operation, race driving and specialized surgery. It may also be of value to train mentally retarded children and older sports persons who have prolonged RT.

Abstract: Feedback from muscles stimulates ventilation at the onset of passive movement. We hypothesized that central neural activity via a cognitive task source would interact with afferent feedback, and we tested this hypothesis by examining the fast changes in ventilation at the transition from rest to passive leg movement, under two conditions: (A) no task, and (B) solving a computer-based puzzle. Resting breathing was greater in condition (B) than in condition (A); evidenced by an increase in mean ± SEM  breathing frequency (18.2 ± 1.1 br·min-1 versus 15.0 ± 1.2 br·min-1, p = 0.004) and ventilation (10.93 ± 1.16 l·min-1 versus 9.11 ± 1.17 l·min-1 p < 0.001). In condition (A) the onset of passive movement produced a fast increase in mean ± SEM breathing frequency (. = 2.9 ± 0.4 br·min-1, p < 0.001), tidal volume (. = 233 ± 95 ml, p < 0.001) and ventilation (. = 6.00 ± 1.76, p < 0.001). However, in condition (B) the onset of   passive movement only produced a fast increase in mean ± SEM breathing frequency (. = 1.3 ± 0.4 br·min-1, p = 0.045), significantly smaller than in condition (A) (p = 0.007). These findings provide evidence for an interaction between central neural cognitive activity and the afferent feedback mechanism, and we conclude that the performance of a cognitive task suppresses the respiratory response to passive movement.

Abstract: Autonomic responses to breath holding were studied in twenty healthy young men. Breath was held at different phases of respiration and parameters recorded were Breath holding time, heart rate systolic and diastolic blood pressure and galvanic skin resistance (GSR). After taking initial recordings all the subjects practised Nadi-Shodhana Pranayama for a period of 4 weeks. At the end of 4 weeks same parameters were again recorded and the results compared. Baseline heart rate and blood pressure (systolic and diastolic) showed a rendency to decrease and both these autonomic parameters were significantly decreased at breaking point after pranayamic breathing. Although the GSR  was recorded in all subjects the observations made were not conclusive. Thus pranayama 6

 breathing exercises appear to alter autonomic responses to breath holding probably by increasing vagal tone and decreasing sympathetic discharges. . Yoga International Reprint Series. Honesdale, Pa.: The Bhastri ka & Kapalabhati

influences lateralized cognitive performance.  Brain and Cognition, 1989, 9:181-190. PMID: 2923709. Abstract: Relative nostril efficiency (nasal cycle) is related to hemispheric EEG differences and performance on cognitive tasks. We investigated how unilateral forced nostril breathing influences spatial and verbal performance. Right-handed males and females performed both tasks under either left-nostril, right-nostril, or free-breathing conditions. Unilateral breathing affects performance differently in males and females. It influences male performance ipsilaterally on both tasks: Their spatial performance is  better during right- nostril breathing, and their verbal performance is better during leftnostril breathing. Unilateral breathing influences female performance contralaterally, but only on the spatial task: Their spatial performance is better during left-nostril breathing. These differences within and between sexes may exist because unilateral nostril breathing differentially activates the two hemispheres and thereby facilitates performance, or   because attempts of the brain to control the nasal cycle unilaterally interfere with  performance.

“According to a new study in the most recent issue of the  British Medical Journal , activities like these that promote slow and deep breathing can positively alter many of the  body’s vital signs. “‘There is a great deal of evidence built up over the last 30 years that breathing exercises are extraordinarily important in health and well being,’ said Dr. Herbert Benson,  president of the Mind/Body Medical Institute in Boston. “The 23 test subjects were told to either recite the rosary in Latin or to repeat a typical yoga mantra that they were taught by an instructor unfamiliar with the study. At no time were the subjects told how long they should take to perform the tasks. “The results of the study found that the slow deep breathing associated with these  practices synchronized the subject’s cardiovascular rhythms, leading to favorable  psychological as well as physiological effects.” Carroll, Michael (Yoganand).

Cysarz, Dick, and Arndt Bussing. Cardiorespiratory synchronization during Zen

meditation. European Journal of Applied Physiology, 7 Jun 2005. Author email: [email protected]. Abstract: The impact of meditation on cardiorespiratory synchronization with respect to  breathing oscillations and the modulations of heart rate induced by respiration (respiratory sinus arrhythmia, RSA) was investigated in this study. Four different exercises (spontaneous breathing, mental task, Zen meditation, and Kinhin meditation) were consecutively performed by nine subjects mainly without any experience in meditation. An electrocardiogram and a respiratory trace were recorded simultaneously. On this basis the degree of cardiorespiratory synchronization was quantified by a technique which has been adopted from the analysis of weakly coupled chaotic oscillators. Both types of meditation showed a high degree of sync hronization, whereas heartbeat and respiration were hardly synchronized during spontaneous breathing. During the mental task exercise the extent of synchronization was slightly higher than during spontaneous breathing. These results were largely determined by the breathing frequency  because the two types of meditation induce low breathing frequencies which led to a  pronounced and in-phase RSA. During the meditation the low breathing frequencies led to a decrease in the high frequency of heart rate variability, whereas the low frequency and the extent of RSA increased. The heart rate primarily reflected the degree of physical effort. The high degree of cardiorespiratory synchronization during meditation in unexperienced meditators suggests that the physiological implications of meditation does not require prior experience in meditation.

“Part healing technique, part performance enhancer, breathwork has been used throughout the world to help victims of trauma, torture and disaster, as well as addicts and athletes. Now, fueled by the popularity of Eastern traditions such as yoga and tai chi,  breath awareness is gaining acceptance in the West as a tool for maintaining good health. “‘Conscious breathing breaks up the habit patterns coded in the body and emotions,’ said Shakta Kaur, a Kundalini yoga teacher in Chicago who leads ‘breathwalk’ classes, which synchronize breathing and walking. ‘You end up transforming yourself, actually changing your body chemistry.’ “Increasingly, science offers support for her claims. Still, although breathing is so basic and essential that it happens whether we’re knocked unconscious or fall asleep, most  people do it incorrectly. “Less than 10 percent of the population breathes efficiently, according to chronic-pain specialist Ingrid Bacci . . .” Desai, B.

Abstract: The present study conducted on twelve normal healthy male subjects showed decrease in blood urea, increase in creatinine and tyrosine after one minute of  Kapalabhati, a fast-breathing technique of Hatha Yoga (120 respiratory strokes (min.). From biochemical point of view the practice of Kapalabhati seems to promote decarboxylation and oxidation mechanisms due to which quieting of respiratory centres is achieved, which is also the prerequisite for the practice of Pranayama, another important technique of Yoga.  ___________, P.

Farrow, J. T., and J. R. Hebert. Breath suspension during the

Transcendental Meditation technique. Psychosomatic Medicine, 1982, 44(2):133-153. Abstract: We observed, over four independent experiments, 565 criterion-meeting episodes of breath suspension in 40 subjects practicing the Transcendental Mediation technique (TM), a simple mental technique involving no breath control procedures. The 17

frequency and length of these breath suspension episodes were substantially and significantly greater for TM subjects than for control subjects relaxing with eyes closed. Voluntary control of respiration was most probably eliminated as an explanation of this  phenomenon by the experimental design and by the use of a variety of nonintrusive respiration transducers, including a two-channel magnetometer, an indirect but accurate means of monitoring respiration. Many TM subjects report experience of a completely quiescent mental state characterized by maintained awareness in the absence of thought. Eleven TM subjects were instructed to press an event mark button after each episode of  this pure consciousness experience. The temporal distribution of button presses was significantly related (p less than 10(-10) to the distribution of breath suspension episodes, indicating that breath suspension is a physiological correlate of some, but not all, episodes of the pure consciousness experience. In an extensive study of a single advanced meditator, pure consciousness experiences were also associated with reduced heart rate; high basal skin resistance; stable phasic skin resistance; markedly reduced mean respiration rate, mean minute ventilation and mean metabolic rate; and statistically consistent changes in EEG power and EEG coherence (an indicator of long-range spatial order in the nervous system).

Abstract: The effects of spontaneous high-frequency breathing (HFB) on lung function were evaluated in three subjects highly trained in the practice of yoga. Transpulmonary  pressure was measured by an esophageal balloon catheter and gas flow by  pneumotachography. The abdominal and rib cage contributions to tidal breathing were measured separately by respiratory inductive plethysmography. Gas exchange was studied by the conventional technique and by multiple inert gas elimination. During HFB, respiratory rate increased to 232 cycles/min with a tidal volume of 0.35 liter. This resulted in a more than 10-fold increase in expired minute ventilation to approximately 90 l/min. The transpulmonary pressure varied by 20 cmH2O, with the calculated elastic, resistive, and accelerative components varying by 2, 20, and 8 cmH2O, respectively. Respiratory work increased more than 200-fold in comparison with resting ventilation. A  phase shift between thoracic and abdominal breathing was observed and was interpreted as a volume displacement of approximately 30 l/min between the two parts of the respiratory system. Arterial oxygen and carbon dioxide tension remained normal. Bohr  dead space increased, while acetone dead space remained unaltered. A bimodal distribution of ventilation-perfusion ratios (VA/Q) was observed, with one mode in normal and another in “high” VA/Q regions.

Mary Guerrera, M.D., writes: “‘I wonder whether the teaching community’s precept could be “Every breath a lesson.”’ When I recently rediscovered this intriguing quote by the respected medical educator, Neal Whitman, Ed.D., an entirely new meaning emerged. In the chapter on this subject, he writes: ‘In the presence of medical students and residents, medical teachers are never not teaching. This notion will not ring true for you if  you equate teaching to giving information. But, if you view teaching as any interpersonal communicative event that occurs because of your desire to help learners, then every  breath is indeed a lesson.’ “For office-based teachers of family medicine, teaching time is not limited to the discussions we have with learners about the patients they have seen. Students and residents also learn from us during many other moments of the day as we navigate the complex and ever-changing sea of clinical practice and teaching roles. They watch our  every move and even our every breath, observing how we reason a differential diagnosis, converse with a worried patient, and communicate with colleagues. They notice not only our solutions to the various challenges that arise during the day but also how  professionally we conduct ourselves in dealing with these issues. Indeed, every breath, word, and action that learners observe are learning potential by role modeling and demonstrating how to address the various issues and challenges of daily practice . . .” Gunstone, Maria.

Irigaray, Luce. Between East and West: From Singularity to Community. Columbia

University Press, 2001. Translated by Stephen Pluhácek. From the publisher: “With this book we see a philosopher well steeped in the Western tradition thinking through ancient Eastern disciplines, meditating on what it means to learn to breathe, and urging us all at the dawn of a new cent ury to rediscover indigenous Asian cultures. Yogic tradition, according to Irigaray, can provide an invaluable means for restoring the vital link between the present and eternity—and for re-envisioning the  patriarchal traditions of the West. “Western, logocentric rationality tends to abstract the teachings of yoga from its everyday  practice—most importantly, from the cultivation of breath. Lacking actual, personal experience with yoga or other Eastern spiritual practices, the Western philosophers who have tried to address Hindu and Buddhist teachings—particularly Schopenhauer—have frequently gone astray. Not so, Luce Irigaray. Incorporating her personal experience with yoga into her provocative philosophical thinking on sexual difference, Irigaray proposes a new way of understanding individuation and community in the contemporary world. She looks toward the indigenous, pre-Aryan cultures of India—which, she argues, have maintained an essentially creative ethic of sexual difference predicated on a respect for  life, nature, and the feminine. “Irigaray’s focus on breath in this book is a natural outgrowth of the attention that she has given in previous books to the elements—air, water, and fire. By returning to fundamental human experiences—breathing and the fact of sexual difference—she finds a way out of the endless sociologizing abstractions of much contemporary thought to rethink questions of race, ethnicity, and globalization.” The author thinks that there should be separate yogas for men and women and that there is no universalized transcendence through yoga, no such thing as “beyond gender,” which is the teaching of all self-transcending traditions.

effects of unilateral forced nostril  breathing on cognitive performance. International Journal of Neuroscience, 1992, 73(12):61-68. PMID: 8132419. Abstract: This study describes the effects of 30 minutes of unilateral forced nostril  breathing on cognitive performance in 51 right-handed undergraduate psychology students (25 males and 26 females). A verbal analogies task modeled after the Miller  Analogies and SAT Tests was used as a test of left-hemispheric performance and mental rotation tasks based on the Vandenburg and Kuse adaptation of Shepard and Metzler's tests were used as spatial tasks for testing right-hemispheric performance. Spatial task   performance was significantly enhanced during left nostril breathing in both males and females, p = .028. Verbal task performance was greater during right nostril breathing, but not significantly p = .14. These results are discussed in comparison to other cognitive and  physiological studies using unilateral forced nostril breathing. This yogic breathing technique may have useful application in treating psychophysiological disorders with hemispheric imbalances and disorders with autonomic abnormalities.

Abstract: Spontaneous pneumothorax is the most common cause of pneumothorax. We report a case of a 29-year-old healthy woman who presentedto the emergency department 27

with a spontaneous pneumothoraxcaused by a yoga breathing technique called  Kapalabhati pranayama, or breath of fire. Yoga breathing exercises are commonly  practiced, and a limited number of studies have shown various physiologic benefits of  yoga breathing. This is the only known report ofspontaneous pneumothorax caused by  pranayama, but some other rare causes are noted.

Professionals. The Breathing Project, Inc., 5 East 22nd Street, #15C, New York, NY 10010, Tel. and fax: (212) 979-9642, e-mail: [email protected]. The Breathing Project is taught by Leslie Kaminoff and consists of 70 classroom hours and 30 workshop hours over the course of nine months. Enrollment in this course is by application and will be limited to twelve participants. Course material will focus on the essential details of spinal and respiratory anatomy and their relation to the practice and teaching of yoga. Some of the topics that will be covered in-depth are: the evolution, structure, and function of the spinal column; the evolution and function of breathing, and its relation to spinal movements; the anatomy and kinesiology of the diaphragm and respiratory mechanism; the Shape/Change® method of breath education and yoga teaching methodology; breath as the integrating  principle of posture, movement, and yoga practice. The bulk of the classroom hours will be focused on providing participants with a clear  understanding of the anatomical and theoretical components of the course. Five weekend workshops will allow for extended practice sessions in which the course material can be experientially applied to the practice and teaching of yoga. Applications for The Breathing Project’s 100-hour course are accepted from any yoga teacher with a minimum of one year’s teaching experience and an understanding of basic anatomy. The application process will include testing of anatomical knowledge. The course will include reading assignments and homework, which will be submitted weekly via e-mail. Leslie Kaminoff, originator and teacher of the course, is a Yoga educator, bodyworker, and breathing therapist inspired by the Viniyoga tradition of T. K. V. Desikachar. He is an internationally recognized specialist in breath anatomy who has led workshops for  many of the leading Yoga associations and schools in America. He currently practices  bodywork, Yoga, and breathing therapy in New York City and Great Barrington, Massachusetts. Leslie’s first book, The Breath Prescription, is based on the material in this course. Kant, S. Evaluation of yogic

breathing exercises on pulmonary functions, free radicals, and antioxidant status among healthy individuals. Paper presented at Annual Meeting of  the American College of Chest Physicians, 25 Oct 2000, San Francisco, California. Thirty healthy volunteers performed yogic breathing exercises 30 minutes every day for  10 weeks. Pulmonary function tests were done initially and at the end of the 10-week  exercise period. Levels of malonaldehyde (an indicator of free radical activity) and

29

superoxide dismutase (an indicator of antioxidant activity) were also collected. Following the exercise period, volunteers showed significant improvement in pulmonary function. Malonaldehyde levels also decreased significantly (9.54+/-0.56 nm/mL before exercises to 8.21 +/-0.76nm/mL after exercises). Superoxide dismutase levels increased, but not significantly (11.60+/-3.14 units/mg to 13.04+/-2.66). Researchers concluded that the  practice of yoga not only improves pulmonary lung function in healthy adults, but may also be helpful in reducing the prevalence of bronchial asthma, chronic obstructive  pulmonary disease, and lung cancer.

in its effect on cardiovascular response to apnoea. Act Nerv Super (Praha), Jun 1990, 32(2):99-114. PMID: 2399805. Abstract: Jalandharabandha (JB) is the important constituent of apnoea (kumbhaka) in hathayogic breathing exercises. It is performed by pressing the chin into the jugular notch and creating thus the positive pressure on the neck region. The influence of JB on the heart rate and vasomotor response was studied in relationship to different lung volumes. The course of R-R intervals is highly significantly different according to the type of  apnoea. JB leads to the diminution of bradycardia, but does not change the position of the maximum and minimum in comparison to the apnoea without JB. Application of JB increases the number of vasodilatations and shortens the latencies of vasodilatations, duration and amplitude of reactions. JB during breath holding decreases the vagal reflex changes and may thus work as a stabilizing component in yogic breathing exercises. Lewis, Dennis. Relaxing

Machander, A. R. Comments on the increase of

intrathoracic pressure in the practice of   pranayama. Jógová Cvicení , 1982, pp. 65-70. [In Czechoslovakian.] Summary: “Both intrathoracic and intraabdominal pressure can be increased during yogic  practice. Abhyantara kumbhaka . . . during pranayama can increase intrathoracic pressure in different degree[s], according to the technique used. The increase of thoracic pressure elevates venous pressure with consequent venous blockade and the increase of pressure  both in cerebrovascular fluid and intracranially. If the breath-holding with increased intrathoracic pressure lasts 45 seconds, it causes stagnant hypoxy of the brain with metabolic changes . . . Thanks to limited venous return, minute heart volume is decreased to one-half with consequent disturbance of cardiac rhythm. Therefore the breath-holding with increased thoracic pressure is not without danger (cerebral stroke, collapse,  paroxysm of epilepsy, coronary infarction). “Pronounced increase of thoracic pressure can be caused by [the] following conditions: 1) if tension of expiratory thoracic muscles is increased after glottis is closed, 2) if uddiyana  bandha is practiced incorrectly, causing abdominal press[ure], 3) if there is relaxation of  diaphragm during breath-holding and increased abdominal pressure expands over it to thoracic cavity. Increased intraabdominal pressure can ha ve negative effect also during asanas, if they are practice with longer breath-holding and with activation of expiratory muscles (e.g., mayurasana, backward bending). “As a consequence we can state that incorrect practicing of certain yogic exercises can endanger especially disposed persons and regular incorrect practice could negatively influence even healthy people.”  ___________. Exercise for correction of right-left activity. Jógová Cvicení , 1982, pp.

131-132. [In Czechoslovakian.] Summary: “Both tradition and modern research show how important is breathing through  both nostrils. It can be reached through asymmetric asanas, when one half of [the] thorax is compressed, the other distended. It influences both the movement of [the] chest wall and through vasomotor reflexes [the] passage through the nostrils. Differences between  both halves of the body must be checked in certain balanced (meditative) postures.” Mackintosh, Sarah.

The present investigation was undertaken to study the effect of yoga training on visual and auditory reaction times (RTs), maximum expiratory pressure (MEP), maximum inspiratory pressure (MIP), 40 mmHg test, breath holding time after 

36

expiration (BHTexp), breath holding time after inspiration (BHTinsp), (BHTinsp), and hand grip strength (HGS). Twenty seven student volunteers were given yoga training for 12 weeks. There was a significant (P < 0.001) decrease in visual RT (from 270.0 +/- 6.20 (SE) to 224.81 +/- 5.76 ms) as well as auditory RT (from 194.18 +/+/- 6.00 to 157.33 +/- 4.85 ms). MEP increased from 92.61 +/- 9.04 to 126.46 +/- 10.75 mmHg, while MIP increased from 72.23 +/- 6.45 to 90.92 +/- 6.03 mmHg, both these changes being statistically statistically significant (P < 0.05). 40 mmHg test and HGS increased significantly (P < 0.001) from 36.57 +/- 2.04 to 53.36 +/- 3.95 s and 13.78 +/- 0.58 to 16.67 +/- 0.49 kg respectively. BHTexp increased from 32.15 +/- 1.41 to 44.53 +/- 3.78s (P < 0.01) and BHTinsp increased from 63.69 +/- 5.38 to 89.07 +/- 9.61 s (P < 0.05). Our results show that yoga  practice for 12 weeks results in significant significant reduction reduction in visual and auditory RTs and significant increase in respiratory pressures, breath holding times and HGS.

Abstract: This study compared the psychological effects of Progressive Muscle Relaxation (PMR) and breathing exercises. Forty-two Forty-two students were divided randomly into two groups and taught PMR or breathing exercises. Both groups practiced for five weeks and were given the Smith Relaxation States Inventory before and after each session. As hypothesized, PMR practitioners practitioners displayed greater increments in relaxation states (R-States) Physical Relaxation and Disengagement, while breathing practitioners displayed higher levels of R-State R-State Strength and Awareness. Slight differences emerged at Weeks 1 and 2; major differences differences eme rged at Weeks 4 and 5. 5 . A delayed and potentially reinforcing reinforcing aftereffect emerged for PMR only after five weeks of training—increased levels of Mental Quiet and Joy.

Abstract: The present study was conducted in trained (n=7) and untrained (n=7) volunteers to determine the effect of savitri pranayam and shavasan on O2 consumption, heart rate and blood pressure. In trained subjects we found a consistent and significant (p<0.01) reduction in O2 consumption within a few minutes of starting savitri pranayam. During shavasan, there was significant reduction in O2 consumption (p<0.05), heart rate (p<0.001) and diastolic blood pressure (p<0.05). In untrained subjects, the changes in above mentioned parameters were statistically statistically insignificant.  ___________, C. Saravanane, S. G. Surange, D. P. Thombre, and A. S. Chakrabarty.

Abstract: Uninostril breathing facilitates the performance on spatial and verbal cognitive tasks, said to be right and left brain functions, respectively. Since hemispheric memory functions are also known to be lateralized, the present study assessed the effects of  uninostril breathing on the performance in verbal and spatial memory tests. School children (N = 108 whose ages ranged from 10 to 17 years) were randomly assigned to four groups. Each group practiced a specific yoga breathing technique: (i) right nostril  breathing, (ii) left nostril breathing, (iii) alternate nostril breathing, or (iv) breath awareness without manipulation of nostrils. These techniques were practiced for 10 days. Verbal and spatial memory was assessed initially and after 10 days. An age -matched control group of 27 were similarly assessed. All 4 trained groups showed a significant increase in spatial test scores at retest, but the control group showed no change. Average increase in spatial memory scores for the trained groups was 84%.

“Sometimes the stresses of our society make us feel like peace is a million miles away. But yoga shows us that it’s right in our reach. As teachers, we must heal our students’ nervous systems by giving them concrete tools to cultivate peace on the mat . . .”

42

In addition to positive uses of  pranayama, the article also cautions: “. . . as teachers, we must be very careful with certain  pranayama practices.  Bhastrika pranayama (often known as ‘Breath of Fire’) can damage or even destroy the nervous system. I’ll never  forget a woman who came to me for legal advice when I was practicing law. She was extremely agitated, constantly distracted, and couldn’t finish a thought or a sentence. I learned that her nervous system was burnt out from years of practicing  pranayama improperly, specifically bhastrika and kapalabhati (Skull-shining breath). When an excess of pranic energy floods the nervous system, it is like a balloon that’s filled with more air than it has the strength to contain. The nervous system is shattered and severe mental trauma can result. The body must be properly prepared with years of asana (especially backbends) to safely receive and contain the power of  prana. “And there are other ways to harm our students with the practice. For instance, the nervous system is agitated by jerky movements. This includes trembling during a pose by working too hard. Remind your students that there is no virtue in holding poses too long, for the benefits quickly unravel and turn into detriments. I have heard some teachers say to their students, ‘Shake it out!’ and encourage their students to shake themselves after  intense poses to release tension. This misses the point. It is far better to be still and melt the tension with awareness.”  ___________. Pranayama CD and audiotape. Available for purchase online:

“The recent research, conducted at the Kaleida Health-Millard Fillmore Hospital in Buffalo, New York, reinforces previous findings that suggest pranayama may help lower   blood pressure. “Researchers took 12 people between the ages of 22 and 55 with normal blood pressure and subjected them to mental stress for five minutes by asking them to perform a frustrating mathematical task. Then they compared the use of controlled breathing—  inhaling and exhaling at a rhythmic pace—with listening to classical music, nature sounds, or no intervention, to measure how long it takes for blood pressure levels to return to normal. “Results showed that classical music made systolic blood pressure (SBP)—the top number that reflects blood pressure when the heart contracts—drop to pre-stressed levels after an average time of 2.9 minutes, nature sounds worked in 3.0 minutes, and doing nothing normalized SBP after 3.7 minutes, whereas deep breathing returned SBP to normal after just 2.7 minutes. “Diastolic blood pressure (DBP) was slower to return to normal, but after four minutes, readings had dropped by 11.2 percent with yogic breathing, compared to 2.7 percent for  the group doing nothing. This suggests that DBP would return to normal levels more quickly with yogic breathing. “Lead researcher B. H. Sung, an associate professor of medicine at the State University of New York at Buffalo, believes that even hypertensive patients would have similar  results, although the higher the blood pressure, the more time it would take for the  pressure to come down. “B. H. Sung and her coresearchers speculate yogic breathing may work by relaxing muscles that constrict blood vessels and changing the signals sent to the brain that announce stress to the body. Sung believes the technique may prove an effective complementary form of therapy to medication and lifestyle changes for hypertensives . . .” Prana and pranayama. Yoga Rahasya, 1998, 5(3).

PMID: 15624085. Abstract: A previous report described selective electrical activity of the cerebral hemispheres with uninostril breathing. In the present study, middle latency auditory evoked potentials (MLAEPs) were recorded from symmetrical scalp sites during the  practice of uninostril Yoga breathing. There were two sessions (40 min each) of right nostril Yoga breathing (RNB) and of breath awareness (BAW), with (i) “before,” (ii) test (either RNB or BAW), and (iii) “after” periods. The participants were 14 male volunteers aged between 18 and 33 years, and the setting was a Yoga center. MLAEPs were recorded from symmetrical scalp sites (C4 and C3). During RNB, the peak amplitudes of  two negative components (i.e., Na wave and Nb wave) were significantly increased on the right side. Increased peak amplitudes of Na and Nb waves suggested that RNB increased the number of neurons recruited on the right side, suggesting a possible application of RNB in certain psychiatric disorders with cerebral hemispheric imbalance.

(Breathing techniques: kapalabhati and alternate nostril breathing.) The following review of this study appears in an article by Ralph La Forge entitled “Spotlight on Yoga” in the May 2001 issue of  IDEA Health and Fitness Source (http://www.findarticles.com/cf_0/m0BTW/5_19/74886169/p1/article.jhtml?term=yoga): Study: Heart rate variability (HRV) is a functional measure of the proficiency of the  parasympathetic nervous system. Greater variability is associated with relaxation and quiescence and a lower risk of major cardiovascular events, such as heart attack. To measure HRV, two spectral components of an electrocardiogram are usually recorded: a high-frequency (0.15-0.50 hertz [Hz]) component, attributable to parasympathetic activity, and a low-frequency component (0.05-0.15 Hz), attributable to sympathetic activity. Researchers at the Vivekananda Kendra Yoga Research Foundation in Bangalore, India, studied HRV during two yoga practices that had previously been found to have opposite effects: sympathetic stimulation (kapalabhati, or breathing at high frequency, i.e., 2  breaths per second for several seconds) and reduced sympathetic activity (nadi shodana, or alternate-nostril breathing). All 12 male volunteers (age range = 21-33 years) were assessed before and after each practice on separate days. Following kapalabhati, low-frequency power and the ratio of low to high frequency increased significantly, whereas high-frequency power fell significantly. There were no significant changes following nadi shodana. According to Raghuraj and colleagues, these results suggest that (1) kapalabhati modifies cardiac autonomic control (nervous system regulation of heart function) by increasing sympathetic activity and reducing vagal (primary parasympathetic nerve) activity and (2) HRV is a more useful  psychophysiological measure than heart rate alone. Comments: HRV is an up-and-coming measure of cardiovascular function in clinical cardiology. HRV cannot be discerned by heart rate palpation or wrist-worn cardiotachometers; it must be measured using very expensive electrocardiographic spectral analysis equipment, such as that found in university-based cardiovascular  research institutions.  ___________, and S.

Abstract: Some reports have described the effects of forced uninostril breathing on autonomic activity as sex-specific, while other reports [have] described selective effects of   breathing through a specific nostril on the two divisions of the autonomic nervous system, irrespective of sex. There are also yoga breathing techniques which involve voluntary uninostril breathing. These techniques also influence the autonomic activity based on the  patent nostril rather than sex. These descriptions were in line with experiential observations of the ancient sages described in classical yoga texts. This paper summarize s these  perspectives on uninostril breathing.

Abstract: Energy expenditure and ventilatory responses to yogic standing posture of  Virasana were studied on 10 healthy men (25-37 years of age). The results of various responses respectively to the horizontal supine, Chair-sitting and Virasana were: Minute Ventilation (VE) 7.64, 8.61 and 18.67 L/min; Respiratory Frequency (FR) 15.71, 15.70 and 21.45 Breath/min; Tidal Volume (VT) 0.496, 0.544 and 0.827 L/min; Oxygen consumption (VO2) 0.127, 0.234 and 0.573 L/min; Carbondioxide Elimination (VCO2) 0.127, 0.134 and 0.420 L/min; Respiratory Exchange Ratio (RER) 0.58, 0.57 and 0.69; Heart Frequency (FH) 65.2, 74.5 and 104.4 beats/min; Oxygen Pulse (O2P) 3.32, 3.17 and 5.45 ml/beat; Ventilatory Equivalent (VE-EQ) 36.78, 37.12 and 33.85; Multiple of Resting VO2 (METS) 0.96, 1.05 and 2.53 and Metabolic Cost (MC) 1.04, 1.13 and 2.76 Cal/min. Virasana  posture was characterised by higher VE, FR, VT, VO2, VCO2, FH and O2P with lesser  VE-EQ. The observations suggest that Virasana induces temporarily a hypermetabolic state characterised by enhanced sympathetic nervous system activity which gets inhibited during the adoption of resting supine shavasana posture.

The art of longevity and the attempts of immortalising the corporeal human body were the ultimate aims of Siddhars as understood from their numerous treatises on the art of  rejuvenation— Thirumular Karpam - 300, Bohar Karpam - 300, Thiruvalluvur Karpam 300, Yugimuni Karpam - 300, etc., which form some of the excellen[t] works in this regard. One of the means to rejuvenate the body was achieved through the art of   breathing (Pranayama) which has a direct bearing on the basal metabolic rate and the span of longevity. In this paper an attempt has been made to throw some light on the scientific basis of the various Kaya Kalpa methods adopted by Siddhars. Raju, P. S., K. A. Kumar, S. S. Reddy, S. Madhavi, K.

Abstract: Twelve normal healthy volunteers (6 males and 6 females) undergoing yoga training for 90 days were studied for the effect of yoga on exercise tolerance. Their ages ranged from 18 to 28 years. The volunteers were taught only Pranayama for the first 20 days and later on yogic asanas were added. Sub-maximal exercise tolerance test was done on a motorized treadmill by using Balke's modified protocol, initially, after 20 days (Phase-I) and after 90 days of yoga training (Phase-II). Pyruvate and lactate in venous  blood and blood gases in capillary blood were estimated immediately before and after the exercise. Minute ventilation and oxygen consumption were estimated before and during the test. Post exercise blood lactate was elevated significantly during initial and Phase-I,  but not in Phase-II. There was significant reduction of minute ventilation and oxygen consumption only in males in Phase-I and II at the time when the volunteers reached their  80% of the predicted heart rate. Female volunteers were able to go to higher loads of  exercise in Phase-I and II.  ___________, S. Madhavi, K. V. Prasad, M. V. Reddy, M. E. Reddy, B. K. Sahay, and K. J. Murthy.

Abstract: The effect of pranayama a controlled breathing practice, on exercise tests was studied in athletes in two phases; sub- maximal and maximal exercise tests. At the end of   phase I (one year) both the groups (control and experimental) achieved significantly higher work rate and reduction in oxygen consumption per unit work. There was a significant reduction in blood lactate and an increase in P/L ratio in the experimental group, at rest. At the end of phase II (two years), the oxygen consumption per unit work  was found to be significantly reduced and the work rate significantly increased in the

48

experimental group. Blood lactate decreased significantly at rest in the experimental group only. Pyruvate and pyruvate- lactate ratio increased significantly in both the groups after exercise and at rest in the experimental group. The results in both phases showed that the subjects who practised pranayama could achieve higher work rates with reduced oxygen consumption per unit work and without increase in blood lactate levels. The  blood lactate levels were significantly low at rest. Rama, Swami. Pranayama.

Effect of Santhi Kriya on certain psychophysiological parameters: A preliminary study.  Indian J Physiol Pharmacol , Apr 1992, 36(2):88-92. PMID: 1506088. (Body weight,  blood pressure, oral temperature, pulse rate, respiration, ECG, and EEG.) Abstract: Santhi Kriya is a mixture of combined yogic practices of breathing and relaxation. Preliminary attempts were made to determine the effect of Santhi Kriya on certain psychophysiological parameters. Eight healthy male volunteers of the age group 25.9 +/- 3 (SD) years were subjected to Santhi Kriya practice daily for 50 minutes for 30 days. The volunteer's body weight, blood pressure, oral temperature, pulse rate, respiration, ECG and EEG were recorded before and after the practice on the 1st day and subsequently on 10th, 20th and 30th day of their practice. They were also given a  perceptual acuity test to know their cognitive level on the 1st day and also at the end of the study i.e., on the 30th day. Results indicate a gradual and significant decrease in the body weight from 1st to 30th day (P less than 0.001) and an increase in alpha activity of the  brain (P less than 0.001) during the course of 30 days of Santhi Kriya practice. Increase of  alpha activity both in occipital and pre- frontal areas of both the hemispheres of the brain denotes an increase of calmness. This study also revealed that Santhi Kriya practice increases oral temperature by 3 degrees F and decreases respiratory rate significantly (P less than 0.05) on all practice days. Other parameters were not found to be altered significantly. It is concluded that the Santhi Kriya practice for 30 days reduces body weight and increases calmness.

Basic science, clinical trials, and selected advanced techniques. Subtle Energies and Energy Medicine Journal , 2001, 12(2). Abstract: This article reviews the published basic science and clinical studies on unilateral forced nostril breathing (UFNB), a subset of yogic breathing (pranayam) techniques that were discovered/devised more than 5000 years ago. The relationship of  UFNB to the ultradian physiological phenomenon called the nasal cycle, a marker of  mind-body states is also reviewed. Basic science studies show how UFNB can effect the autonomic nervous system, central nervous system (including cognition), and general metabolic activities. Clinical trials on the application to angina pectoris and obsessive compulsive disorder are described. In addition, three selected advanced UFNB techniques are described; one for stimulating the immune system; one for developing a comprehensive, comparative, and intuitive mind; and a third for developing an enlightened-transcendent mind. These three techniques are part of the ancient science of  Kundalini Yoga as taught by Yogi Bhajan.  ___________. M. R. Boyle, and M. E. Buebel. The

effects of unilateral forced nostril  breathing on cognition. International Journal of Neuroscience, 1991, 57:239-249. Abstract: Ultradian rhythms of alternating cerebral dominance have been demonstrated in humans and other mammals during waking and sleep. Human studies have used the methods of psychological testing and electroencephalography (EEG) as measurements to identify the phase of this \natural endogenous rhythm. The periodicity of this rhythm approximates 1.5 – 3 hours in awake humans. This cerebral rhythm is tightly coupled to another ultradian rhythm known as the nasal cycle, which is regulated by the autonomic nervous system, and is exhibited by greater airflow in one nostril, later switching to the other side. This paper correlates uninostril airflow with varying ratios of verbal/spatial 54

 performance in 23 right-handed males. Relatively greater cognitive ability in one hemisphere corresponds to unilateral forced nostril breathing in the contralateral nostril. Cognitive performance ratios can be influenced by forcibly altering the breathing pattern.  ___________, and B. Kennedy. The

effects of unilateral forced nostril breathing on the heart. International Journal of Neuroscience, Nov 1993, 73(1-2):47-60. Abstract: Three experiments are described that employ impedance cardiography to monitor the effects of unilateral forced nostril breathing (UFNB) on the heart. Experiment 1 includes 7 subjects (4 males, 3 females) with a respiratory rate of 6  breaths/min (BPM). Experiment 2 includes 16 trials using one subject to examine the intraindividual variability, at 6 BPM. Experiment 3 includes 10 trials with the same subject in experiment 2, but with a respiratory rate of 2-3 breaths/s. This rapid rate of  respiration is a yogic breathing technique called "breath of fire" or "kapalabhatti" and employs a very shallow but rapid breath in which the abdominal region acts like a  bellows. All 3 experiments demonstrated that right UFNB increases heart rate (HR) compared to left. Experiment 1 gave 7 negative slopes, or lowering in HR with left nostril  breathing and 7 positive slopes, or increases in HR with right nostril breathing, p = .001. The second and third experiments showed differences in HR means in which right UFNB increases HR more than left, p = .013, p = .001, respectively. In experiment 2 stroke volume was higher with left UFNB, p = .045, compensating for lower HR. Left UFNB increased end diastolic volume as measured in both experiments 1 and 2, p = .006, p = .001, respectively. These results demonstrate a unique unilateral effect o n sympathetic stimulation of the heart that may have therapeutic value. Shantikumar, Yogacharya. The Science of Yogic Breathing (Pranayama).

Summary: The present study was undertaken to observe the energy cost and different cardiorespiratory changes during the practice of  sûrya-namaskara. Twenty-one male 55

volunteers from the Indian Army practiced selected yogic exercises six days a week for  three months. The practice schedule consisted of Hatha-Yoga âsanas (28 min),  prânâyâma (10.5 min), and meditation (5 min). Subjects first practiced kapâla-bhâti  prânâyâma for 2 min, then  yoga-mudrâ for 2 min; after that they rested until oxygen consumption and heart rate (HR) came to resting value. Subjects subsequently performed SN for 3 min 40 sec on average. After three months of training, subjects performed the entire yogic practice schedule in the laboratory, and measurements were taken. Their   pulmonary ventilation, carbon dioxide output, oxygen consumption, HR, and other  cardiorespiratory parameters were measured during the actual practice of SN. Oxygen consumption was highest in the eighth posture (1.22+/-0.073 1 min(-1)) and lowest in the first posture (0.35+/-0.02 1 min(-1)). Total energy cost throughout the practice of SN was 13.91 kcal and at an average of 3.79 kcal/min. During practice, the highest HR was 101+/-13.5 bpm. As an aerobic exercise SN seems to be ideal, as it involves both static stretching and the slow dynamic component of exercise with optimal stress on the cardiorespiratory system.

Abstract: We tested whether chemoreflex sensitivity could be affected by the practice of  yoga, and whether this is specifically because of a slow breathing rate obtained during yoga or as a general consequence of yoga. We found that slow breathing rate per se substantially reduced chemoreflex sensitivity, but long-term yoga practice was responsible for a generalised reduction in chemoreflex. Stancák, A., Jr., M.

yogic high-frequency respiration. Physiol Res., 1991, 40(3):345-354. PMID: 1751482.

Yogic high-frequency respiration—kapalabhati (KB)—was studied in 24 subjects from a  point of rhythmicity. Respiratory movements, blood pressure and R-R intervals of ECG were recorded in parallel and evaluated by spectral analysis of time series. Respiratory signals during KB were modulated by 0.1 Hz rhythm in 82% of experiments. This component was also present in R-R intervals and blood pressure during KB. Frequency (0.2-0.3 Hz) was observed in 67% of respiratory records. The presence of the component 0.2-0.3 Hz in respiration was dependent on resting respiratory frequency. This frequency component was reduced in R-R intervals but increased in blood pressure during kapalabhati as compared to that at rest. The occurrence of both frequency components in respiration during KB supports the hypothesis about the integrative role of cardiovascular  and respiratory rhythms in physiological states characterized by altered respiratory frequency.  ___________, M.

Kapalabhati: Yogic cleansing exercise. II. EEG topography analysis. Homeostasis, 1991, 33:182-189. PMID: 1818698.

Abstract: Topography of brain electrical activity was studied in 11 advanced yoga  practitioners during yogic high-frequency breathing kapalabhati (KB). Alpha activity was increased during the initial five min of KB. Theta activity mostly in the occipital region was increased during later stages of 15 min KB compared to the pre-exercise period. Beta 1 activity increased during the first 10 min of KB in occipital and to a lesser degree in  parietal regions. Alpha and beta 1 activity decreased and theta activity was maintained on the level of the initial resting period after KB. The score of General Deactivation factor  from Activation Deactivation Adjective Checklist was higher after KB exercise than  before the exercise. The results suggest a relative increase of slower EEG frequencies and relaxation on a subjective level as the after effect of KB exercise.  ___________, M. Kuna, Srinivasan, S.

Kapalabhati: Yogic cleansing exercise. I. Cardiovascular and respiratory changes.  Homeost Health Dis, Oct 1991, 33(3):126-34. PMID: 1818666. Abstract: We studied cardiovascular and respiratory changes during yogic breathing exercise kapalabhati (KB) in 17 advanced yoga practitioners. The exercise consisted in fast shallow abdominal respiratory movements at about 2 Hz frequency. Blood pressure, ECG and respiration were recorded continuously during three 5 min periods of KB and during pre- and post-KB resting periods. The beat-to-beat series of systolic blood  pressure (SBP) and diastolic blood pressure (DBP), R-R intervals and respiration were analysed by spectral analysis of time series. The mean absolute power was calculated in three frequency bands--band of spontaneous respiration, band of 0.1 Hz rhythm and the low-frequency band greater than 15 s in all spectra. The mean modulus calculated  between SBP and R-R intervals was used as a parameter of baroreceptor-cardiac reflex sensitivity (BRS). Heart rate increased by 9 beats per min during KB. SBP and DBP increased during KB by 15 and 6 mmHg respectively. All frequency bands of R-R  interval variability were reduced in KB. Also the BRS parameter was reduced in KB. The amplitude of the high-frequency oscillations in SBP and DBP increased during KB. The low-frequency blood pressure oscillations were increased after KB. The results point to decreased cardiac vagal tone during KB which was due to changes in respiratory pattern and due to decreased sensitivity of arterial baroreflex. Decreased respiratory rate and increased SBP and low-frequency blood pressure oscillations after KB suggest a differentiated pattern of vegetative activation and inhibition associated with KB exercise.

ventilatory response to CO2 in subjects practicing hatha-yoga. Journal of Applied   Physiology, 1981, 51:1625-1629. Abstract: We studied eight Belgian subjects well advanced in the practice ofhatha-yoga and compared them with eight sex-, age-, and height-matchedcontrol subjects. Practice of  yoga (range 4-12 yr) involves control of  posture and manipulation of breathing, including slow near-vital capacitymaneuvers accompanied by apnea at end inspiration and end expiration. Average values for the yoga and the control group (in parentheses) are as follows: ventilation (VE) 5.53 1 X min-1 (7.07); tidal volume (VT), 1.03 liters (0.56); rate of breathing, 5.5 min-1 (13.4); end-tidal PCO2, 39.0 Torr (35.3). All differences are significant (P less than 0.05). Ventilatory response to CO2 (rebreathing technique) was significantly lower in the yoga group (P less than 0.01). The regression relating VE to VT during rebreathing of CO2 was VE = 8.1 (VT - 0.23) for the yoga group andVE = 15.8 (VT - 0.16) for the control group (P less than 0.005). We attribute these changes to chronic manipulation of respiration. Steffensen, Sharon.

of Buddhist meditation on serum cortisol and total protein levels, blood pressure, pulse rate, lung volume and reaction time. Physiology and Behavior , Sep 1991, 50(3):543-548. PMID: 1801007. Abstract: Serum cortisol and total protein levels, blood pressure, heart rate, lung volume, and reaction time were studied in 52 males 20-25 years of age practicing Dhammakaya Buddhist meditation, and in 30 males of the same age group not practicing meditation. It was found that after meditation, serum cortisol levels were significantly reduced, serum total protein level significantly increased, and systolic pressure, diastolic pressure and  pulse rate significantly reduced. Vital capacity, tidal volume and maximal voluntary ventilation were significantly lower after meditation than before. There were also significant decreases in reaction time after meditation practice. The percentage decrease in reaction time during meditation was 22%, while in subjects untrained in meditation, the percentage decrease was only 7%. Results from these studies indicate that practising Dhammakaya Buddhist meditation produces biochemical and physiological changes and reduces the reaction time. Svoboda, Robert E. Cultivating

Abstract: According to ancient Indian and Chinese texts the subtle energy (prana or chi) flows through several thousand anatomically indistinguishable channels or meridians (nadis). Three channels are especially important (ida, pingala, and sushumna). The ida and pingala channels correlate with left and right uninostril breathing, respectively. Like yin and yang, they are considered to represent the masculine and feminine principles  present in all creation irrespective of sex. From this perspective these principles are

60

assumed to be present simultaneously in persons of both sexes. This suggests that any sex-specific effects of uninostril breathing may be associated with sex-based  physiological differences, not with ‘masculine’ and ‘feminine’ attributes of the channels (and the corresponding nostrils).  ___________, and T. Desiraju. Oxygen consumption during pranayamic type of very

slow-rate breathing. Indian Journal of Medical Research, Oct 1991, 94:357-363. PMID: 1794892.

Abstract: To determine whether the yogic Ujjayi pranayamic type of breathing that involves sensory awareness and consciously controlled, extremely slow-rate breathing including at least a period of end-inspiration breath holding in each respiratory cycle would alter oxygen consumption or not, ten males with long standing experience in  pranayama, and volunteering to participate in the laboratory study were assessed. These subjects aged 28-59 yr, had normal health appropriate to their age. Since kumbhak (timed  breath holding) is considered as an important phase of the respiratory cycle in the  pranayama, they were categorised into two groups of five each, one group practising the short kumbhak varieties of pranayama, and the other the long kumbhak varieties of   pranayama. The duration of kumbhak phase was on an average 22.2 percent of the respiratory cycle in the short kumbhak group, and 50.4 per cent in the long kumbhak  group. The oxygen consumption was measured in test sessions using the closed circuit method of breathing oxygen through the Benedict-Roth spirometer. Each subject was tested in several repeat sessions. Values of oxygen consumption of the period of   pranayamic breathing, and of post-pranayamic breathing period, were compared to control value of oxygen consumption of the prepranayamic breathing period of each test session. The results revealed that the short kumbhak pranayamic breathing caused a statistically significant increase (52%) in the oxygen consumption (and metabolic rate) compared to the pre-pranayamic base-line period of breathing. In contrast to the above, the long kumbhak pranayamic breathing caused a statistically significant lowering (19% of the oxygen consumption (and metabolic rate).  ___________, and T. Desiraju.

Alterations of auditory middle latency evoked potentials during yogic consciously regulated breathing and attentive state of mind. International Journal of Psychophysiology, May 1993, 14(3):189198. PMID: 8340237. Abstract: Middle latency auditory-evoked potentials (AEP-MLRs) of 10 healthy male subjects in the age range of 21-33 years, were assessed to determine whether yogic  pranayamic practice would cause changes in them. The pranayama type assessed here is an exercise of consciously-controlled rhythmic breathing involving timed breath-holding in each cycle of breathing, while the subject holds utmost attention and experiences the touch of inhaled air in the nasal passage [Ujjayi and Bhastrika type of pranayama]. The results revealed that the Na-wave amplitude increased and latency decreased during the

61

 period of pranayamic practice, whereas the Pa-wave was not significantly altered. The change is interpreted as an indication of a generalized alteration cause in information  processing at the primary thalamo-cortical level during the concentrated mental exercise of inducing modifications in neural mechanisms regulating a different functional system (respiratory). Further [research is] required to understand the operational significances of  such changes.  ___________, R. Nagarathna, and H. R. Nagendra. Breathing through a particular

PMID: 8063359 Abstract: There is increasing interest in the fact that breathing exclusively through one nostril may alter the autonomic functions. The present study aimed at checking whether  such changes actually do occur, and whether breathing is consciously regulated. 48 male subjects, with ages ranging from 25 to 48 years were randomly assigned to different groups. Each group was asked to practice one out of three pranayamas (viz. right nostril  breathing, left nostril breathing or alternate nostril breathing). These practices were carried out as 27 respiratory cycles, repeated 4 times a day for one month. Parameters were assessed at the beginning and end of the month, but not during the practice. The “right nostril pranayama” group showed a significant increase, of 37% in baseline oxygen consumption. The “alternate nostril” pranayama group showed an 18% increase, and the left nostril pranayama group also showed an increase, of 24%. This increase in metabolism could be due to increased sympathetic discharge to the adrenal medulla. The “left nostril Pranayama” group showed an increase in volar galvanic skin resistance, interpreted as a reduction in sympathetic nervous system activity supplying the sweat glands. These results suggest that breathing selectively through either nostril could have a marked activating effect or a relaxing effect on the sympathetic nervous system. The therapeutic implications of being able to alter metabolism by changing the breathing  pattern have been mentioned.  ___________, R. Nagarathna, and H. R. Nagendra. Physiological measures of right

nostril breathing. Journal of Alternative and Complementary Medicine, 1996, 2(4):479484. PMID: 9395677.

Abstract: This study was conducted to assess the physiological effects of a yoga  breathing practice that involves breathing exclusively through the right nostril. This  practice is called surya anuloma viloma pranayama (SAV). Twelve volunteers (average age 27.2 years +/- 3.3 years, four males) were assessed before and after test sessions conducted on two consecutive days. On one day the test session involved practicing SAV  pranayama for 45 minutes (SAV session). During the test period of the other day, subjects were asked to breathe normally for 45 minutes (NB session). For half the  patients (randomly chosen) the SAV session was on the first day and the NB session on the next day. For the remaining six patients, the order of the two sessions was reversed. After the SAV session (but not after the NB) there was a significant (P < .05, paired t test) increase in oxygen consumption (17%) and in systolic blood pressure (mean increase 9.4 mm Hg) and a significant decrease in digit pulse volume (45.7%). The latter 

62

two changes are interpreted to be the result of increased cutaneous vasoconstriction. After   both SAV and NB sessions, there was a significant decrease in skin resistance (two factor  ANOVA, Tukey test). These findings show that SAV has a sympathetic stimulating effect. This technique and other variations of unilateral forced nostril breathing deserve further study regarding therapeutic merits in a wide range of disorders.  ___________, S. Narendran, P. Raghuraj, R.

Abstract: The present study was conducted to evaluate a statement in ancient yoga texts that suggests that a combination of both “calming” and “stimulating” measures may be especially helpful in reaching a state of mental equilibrium. Two yoga practices, one combining “calming and stimulating” measures (cyclic meditation) and the other, a “calming” technique (shavasan), were compared. The oxygen consumption, breath rate, and breath volume of 40 male volunteers (group mean +/- SD, 27.0 +/- 5.7 years) were assessed before and after sessions of cyclic meditation (CM) and before and after  sessions of shavasan (SH). The 2 sessions (CM, SH) were 1 day apart. Cyclic meditation includes the practice of yoga postures interspersed with periods of supine relaxation. During SH the subject lies in a supine position throughout the practice. There was a significant decrease in the amount of oxygen consumed and in breath rate and an increase in breath volume after both types of sessions (2-factor ANOVA, paired t test). However, the magnitude of change on all 3 measures was greater after CM: (1) Oxygen consumption decreased 32.1% after CM compared with 10.1% after SH; (2) breath rate decreased 18.0% after CM and 15.2% after SH; and (3) breath volume increased 28.8% after CM and 15.9% after SH. These results support the idea that a combination of yoga  postures interspersed with relaxation reduces arousal more than relaxation alone does. Tigunait, Pandit Rajmani.

Abstract: Ten healthy, untrained volunteers (nine females and one male), ranging in age from 18-27 years, were studied to determine the effects of hatha yoga practice on the health-related aspects of physical fitness, including muscular strength and endurance, flexibility, cardiorespiratory fitness, body composition, and pulmonary function. Subjects were required to attend a minimum of two yoga classes per week for a total of 8 weeks. Each yoga session consisted of 10 minutes of pranayamas (breath-control exercises), 15 minutes of dynamic warm-up exercises, 50 minutes of asanas (yoga postures), and 10 minutes of supine relaxation in savasana (corpse pose). The subjects were evaluated  before and after the 8-week training program. Isokinetic muscular strength for elbow extension, elbow flexion, and knee extension increased by 31%, 19%, and 28% (p<0.05), respectively, whereas isometric muscular endurance for knee flexion increased 57% (p<0.01). Ankle flexibility, shoulder elevation, trunk extension, and trunk flexion increased by 13% (p<0.01), 155% (p<0.001), 188% (p<0.001), and 14% (p<0.05), respectively. Absolute and relative maximal oxygen uptake increased by 7% and 6%, respectively (p<0.01). These findings indicate that regular hatha yoga practice can elicit improvements in the health-related aspects of physical fitness. Copyright © 2001 CHF, Inc.

Abstract: Systolic tire intervals (STI) are non-invasive and sensitive tests for measuring the ventricular performance. It has been reported that practice of  pranayam modulates cardiac autonomic status and improves cardio-respiratory functions. Keeping this in view, the present study was designed to determine whether  pranayam training has any effect on ventricular performance as measured by STI and cardiac autonomic function tests (AFT). Twenty-four school children were randomly divided into two groups of  twelve each. Group I  (pranayam group) subjects were given training in nadishuddhi, mukh-bhastrika, pranav and savitri pranayams and practised the same for 20 minutes daily for a duration of 3 months. Group II (control group) subjects were not given any  pranayam training. STI (QS2, LVET and PEP) and AFT (RRIV and QT/QS2 ) were

64

measured in both the groups at the beginning and again at the end of three months study  period.  Pranayam training produced an increase in RRIV and a decrease in QT/QS2 suggesting an enhanced parasympathetic and blunted sympathetic activity respectively. QS2, PEP and PEP/LVET increased significantly, whereas LVET was reduced significantly in pranayam group. In contrast, the changes in STI and AFT were much less marked in the control group. Our study shows that three months of  pranayam training modulates ventricular performance by increasing parasympathetic activity and decreasing sympathetic activity. Further studies on a larger sample size may illustrate the underlying mechanism(s) involved in this alteration.  ___________, R. H. Singh, and R. M. Shettiwar. Physiological and biochemical studies

Abstract: This study tested the effectiveness of Ian Jackson’s “BreathPlay” method of  respiration. BreathPlay uses a pattern of forceful expirations and less forceful inspirations in varying ratios. The experimental (E) and control (C) subjects (N = 15 and 10) were volunteers from local USCF clubs. All subjects participated in a maximal OXT (I) on their own bicycles mounted on a wind-load trainer. Following I, E worked 12 hrs. with Jackson over three days learning BreathPlay. Both groups were retested in the following 10 days (II). Percent changes from I to II were evaluated during the t-tests. Significant gains from I to II by E versus C include time to exhaustion, 7.2 vs 0%, (p<.05). Decrease in submaximal ER and RPE, 4.7 vs 2.8% and 9.6 vs 4.6% (p<.01, p<.02). Peak %CO2 occurred 26.8 later vs 14.8% earlier for C (p<.001. Time of RQ = 1.0 was extended 2.0 minutes for E vs .85 minutes for C (p<.20). Anaerobic threshold (AT) was delayed for  2.0 minutes for E in II. Submaximal VCO2 and %CO2 was decreased for E vs C, 9.8 vs 0.8% (p<.05). For racing cyclists BreathPlay increases endurance and delays onset of AT. Discussion: It is a commonly held belief that there is little or no enhanced athletic  performance with voluntary breath patterning by healthy subjects for activities other than swimming. The purpose of the present investigation was to determine if an experimental  basis exists for anecdotal reports for the effectiveness of the BreathPlay technique of  voluntary ventilatory patterning (VVP) for racing cyclists. The results of the present study suggest that endurance cycling performance may be enhanced by voluntary breath patterning in which cyclists exaggerate the force and duration of exhalation. Cyclists using this technique demonstrated a significant increase in time to exhaustion. The improved endurance performance was accompanied by significantly lower submaximal V02 HR and RPE in those cyclists using VVF. The lower  VO2’s may have been the result of increased ventilatory efficiency. If ventilatory

65

efficiency increases with VVP then a lower value for the oxygen cost of breathing (OCB) may be expected. Since the OCB can rise to 10% of VO2 during exercise a reduction could significantly reduce total body oxygen consumption. It has also been hypothesized that distraction from the sensation of effort can reduce the HR and RPE response to exercise. The concentration required to perform VVP may therefore be in part responsible for the lower values observed in the cyclists using the experimental technique. A second explanation for the lower HRs may be that a reduction in intrathoracic pressure may occur during the prolonged exhalation. A reduced intrathoracic pressure would reduce impedance to venous return that would in turn facilitate an increased stroke volume and decreased HR while maintaining the required cardiac output. It is interesting to note that the increase in endurance times observed in the experimental group was not accompanied by an increase in VO2 peak under the same condition. The improve endurance performance would therefore seem to be related to the lower  submaximal VO2 and the observed delay in inset of the anaerobic threshold. Much additional research regarding the potentia l of VVP remains to be performed before it may be recommended as an ergogenic aid. At present the results appear promising and suggest a role for VVP to enhance the endurance performance of racing cyclists. The use of breath as a natural tranquilizer. L’yx ,

Vital capacity, tidal volume and breath holding were significantly higher in short and long term meditators than nonmeditators. Long term meditators has significantly higher vital capacity and expiratory pressure than short and long term meditators than nonmeditators. Long term meditators had significantly higher vital capacity and expiratory pressure than short term meditators. Diastolic blood  pressure was significantly lower in both short and long term meditators as compared to nonmeditators. Heart rate was significantly lower in long term meditators than in short

Alternating cerebral hemispheric activity and lateralization of autonomic nervous function.  Human Neurobiology, 1983, 2:39-43. PMID: 6874437. Abstract: Alternating dominance of cerebral hemispheric activity was demonstrated in humans by use of the electroencephalogram (EEG). Relative changes of electrocortical activity have a direct correlation with changes in the relative nostril dominance, the socalled nasal cycle. The nasal cycle is a phenomenon where efficiency of breathing alternates predominantly through right or left nostril with a periodicity ranging from 25 to greater than 200 minutes. Relatively greater integrated EEG value in one hemisphere correlates with predominant airflow in the contralateral nostril, defining a new interrelationship between cerebral dominance and peripheral autonomic nervous function.  ___________, R.

hemispheric stimulation by uninostril forced nostril breathing. Human Neurobiology, 1987, 6:165171. PMID: 3449485. Abstract: We have previously demonstrated by the integration of EEG amplitudes, that an ultradian rhythm of alternating cerebral dominance exists in humans. This rhythm is tightly coupled with the nasal cycle, since its lateralization correlates with shifts in airflow through the left and right nostrils, where relatively greater integrated amplitudes in one hemisphere correspond to predominant airflow in the contralateral nostril. The nasal cycle is known to be regulated by the sympathetic and parasympathetic branches of  the autonomic nervous system. This dynamic lateralization of alternating activity in the autonomic nervous system exists in other peripheral structures and is also likely to be the mode of regulation of the cortical rhythm. This paper shows that forced nostril breathing 67

in one nostril produces a relative increase in the EEG amplitude in the contralateral hemisphere. This phenomena was demonstrated in 5 out of 5 untrained subjects. These results suggest the possibility of a non-invasive approach in the treatment of states of   psychopathology where lateralized cerebral dysfunction have been shown to occur.

Abstract: The effects of three different procedures, relaxation, visualization and yogic  breathing (pranayama) and stretch on perceptions of physical and mental energy and on  postive and negative mood states have bee nassessed in a group of normal volunteers (N = 71, age range 21-76). Pranayama produced a significantly greater increase in  perceptions of mental and physical energy and feelings of alertness and enthusiasm than the other two procedures (P < 0.5). Rela xation made subjects significantly more sleepy and sluggish immediately after the session than pranayama (P < 0.05). Visualization made them more sluggish but less content than pranayama (P < 0.05) and more upset than relaxation after the second session (P < 0.05). Thus, a 30 min programme of yogic stretch and breathing exercises which is simple to learn and which can be practised even by the elderly had a markedly “invigorating” effect on perceptions of both mental and physical energy and increased high positive mood. A more extensive investigation is planned to establish whether such a programme can readily be incorporated into everyday life, and with what long-term results. Xerri, Philip. Pranayama:

Subtle Energies and Energy Medicine Journal , 2001, 12(2).

Abstract: Life begins and ends with breath. Slight bodily changes are brought about by alteration in the mechanisms of breath. In addition, mental changes are also influenced by  breath. Our general condition of well-being is dependent upon the rhythmic cycles of   breathing within us. Similarly, emotions change the rhythm of breath and when we  become overexcited, then we lose control over the breath. By gaining control of the  breath then we gain mastery of mind and body. Not only that, we also establish a connection with the world around us, of which we are part, through the breath. Two specific healing initiatives based upon breath are used as illustration of breath both as a subtle organizing property and as a material manifestation. The first example is the use of breath through singing to intentionally organize the physiological abilities of  another person as they recover from coma. Singing is literally the intentional use of  69

 breath to heal realized through a particular therapeutic form, which is improvised music therapy. A fundamental property of breathing is that it has rhythm. In musical terms, rhythm has to have the property of intention otherwise it would be simply cyclic repetition or pulse. The second healing initiative is that of Qigong Yangsheng for the treatment of asthma. Breathing is used here also as an intentional activity, this time by the  patient to improve his or her own breathing abilities and to heal what is essentially a  breathing problem, the material manifestation of air-flow. In this latter example, the healer acts as a teacher and guide for the sufferer to influence her own breathing. [Changes in body equilibrium response caused by breathing.

The respiratory response to passive limb movement is suppressed by a cognitive task.  Journal of Applied Physiology, 2004. Author email:  [email protected]. Bell, Harold J., and James Duffin.

Abtract: Feedback from muscles stimulates ventilation at the onset of passive movement. We hypothesized that central neural activity via a cognit ive task source would interact with afferent feedback, and we tested this hypothesis by examining the fast changes in ventilation at the transition from rest to passive leg movement, under two conditions: (A) no task, and (B) solving a computer-based puzzle. Resting breathing was greater in condition (B) than in condition (A); evidenced by an increase in mean ± SEM breathing frequency (18.2 ± 1.1 br min-1 versus 15.0 ± 1.2 br min-1, p = 0.004) and ventilation (10.93 ± 1.16 l min-1 versus 9.11 ± 1.17 l min-1 p < 0.001). In condition (A) the onset of   passive movement produced a fast increase in mean ± SEM breathing frequency ( = 2.9 ± 0.4 br min-1, p < 0.001), tidal volume ( = 233 ± 95 ml, p < 0.001) and ventilation ( = 6.00 ± 1.76 l min-1, p < 0.001). However, in condition (B) the onset of passive movement only produced a fast increase in mean ± SEM breathing frequency ( = 1.3 ± 0.4 br min-1,  p = 0.045), significantly smaller than in condition (A) (p = 0.007). These findings provide evidence for an interaction between central neural cognitive activity and the afferent feedback mechanism, and we conclude that the performance of a cognitive task  suppresses the respiratory response to passive movement.

Abstract: BACKGROUND: It is well established that a depressed baroreflex sensitivity may adversely influence the prognosis in patients with chronic heart failure (CHF) and in those with previous myocardial infarction. METHODS AND RESULTS: We tested whether a slow breathing rate (6 breaths/min) could modify the baroreflex sensitivity in 81 patients with stable (2 weeks) CHF (age, 58+/-1 years; NYHA classes I [6 patients], II [33], III [27], and IV [15]) and in 21 controls. Slow breathing induced highly significant increases in baroreflex sensitivity, both in controls (from 9.4+/-0.7 to 13.8+/-1.0 ms/mm Hg, P<0.0025) and in CHF patients (from 5.0+/-0.3 to 6.1+/-0.5 ms/mm Hg, P<0.0025), which correlated with the value obtained during spontaneous breathing (r=+0.202, P=0.047). In addition, systolic and diastolic blood pressure decreased in CHF patients (systolic, from 117+/-3 to 110+/-4 mm Hg, P=0.009; diastolic, from 62+/-1 to 59+/-1 mm Hg, P=0.02). CONCLUSIONS: These data suggest that in patients with CHF, slow  breathing, in addition to improving oxygen saturation and exercise tolerance as has been  previously shown, may be beneficial by increasing baroreflex sensitivity.  ___________, Giammario Spadacini, Jerzy Bellwon, Ramiz Hajric, Helmut Roskamm, and Axel W.

The training of respiratory muscles decreases respiratory work and at the same time achieves higher levels of blood oxygen. This is of special importance for cardiac patients since the low blood oxygen common in cardiac patients “may impair skeletal muscle and metabolic function, and lead to muscle atrophy and exercise intolerance.” Patients in this study who were trained to slow down their breathing via special deep-breathing techniques achieved higher blood oxygen levels and were able to perform better on exercise tests. (The optimum breath rate was found to be 6 breaths per minute, as opposed to the average resting rate of 12-14 breaths per minute.) Brener, J., and D. Hothersall.

medical illness: Clinical application and evidence of immunoenhancement. Subtle Energies and   Energy Medicine Journal , 2001, 12(2). Abstract: The term “transformational breath work” commonly refers to techniques which use the breath for inducing altered states of consciousness to promote healing on any level. This paper describes common elements of transformational breath work and rationale for its use in medical illness. It then describes the use of one form, Evocative Breath Therapy (EBT), TM within a group mind/body medicine program. The technique employs an hour-long, four-stage process of focused awareness on the breath accompanied by guided imagery and evocative music. It is designed to induce an altered state of consciousness that promotes expanded self-awareness, self-acceptance, selfcompassion, a sense of inner peace, and release of emotional and physical tension. A  pilot study was conducted to determine the impact of EBTTM on one indicator of  immune function, salivary immunoglobulin A (S-IgA). A heterogeneous sample of fortyfive adults (21 cancer patients, 22 healthy others, 2 with other illnesses) contributed saliva samples before and immediately after the experience. A 46.3% increase in S-IgA was found ( p = 0.0123, paired-differences t-test). There were no significant differences  between cancer patients and others. Effect strength was moderate, .278. Leave-one-out analysis found the effect strength to decrease only marginally, suggesting the results are likely generalizeable to independent random samples.

Abstract: The objective of this study was to investigate the synchronization between lowfrequency breathing patterns and respiratory sinus arrhythmia (RSA) of heart rate during guided recitation of poetry, i.e., recitation of hexameter verse from ancient Greek  literature performed in a therapeutic setting. Twenty healthy volunteers performed three different types of exercises with respect to a cross-sectional comparison: 1) recitation of  hexameter verse, 2) controlled breathing, and 3) spontaneous breathing. Each exercise was divided into three successive measurements: a 15-min baseline measurement (S1), 20 min of exercise, and a 15- min effect measurement (S2). Breathing patterns and RSA were derived from respiratory traces and electrocardiograms, respectively, which were recorded simultaneously using an ambulatory device. The synchronization was then quantified by the index , which has been adopted from the analysis of weakly coupled chaotic oscillators. During recitation of hexameter verse, was high, indicating prominent cardiorespiratory synchronization. The controlled breathing exercise showed cardiorespiratory synchronization to a lesser extent and all resting periods (S1 and S2) had even fewer cardiorespiratory synchronization. During spontaneous breathing, cardiorespiratory synchronization was minimal and hardly observable. The results were largely determined by the extent of a low-frequency component in the breathing oscillations that emerged from the design of hexameter recitation. In conclusion, recitation of hexameter verse exerts a strong influence on RSA by a prominent lowfrequency component in the breathing pattern, generating a strong cardiorespiratory synchronization. Limbic autonomic arousal: Its physiological classification and review of the literature. Clinical Electroencephalography, 1991, 22(1):46-60. Deshmukh, V. D.

Abstract; The object of this article is to present a novel physiological classification of  Limbic-Autonomic (LA) arousal on the basis of human physiological data, specifically the oro-nasal breathing patterns in man. It is proposed that the multidimensional LA arousal can be classified into five grades: Grade I: Non-nasal (NN) or oral breathing with  bilateral nasal congestion, and nonactive behavior, Grade II: Left Nasal (LN) breathing and quiet behavior, Grade III: Right Nasal (RN) breathing and active behavior, Grade IV: Bilateral Nasal (BN) breathing and very active behavior, and Grade V: Oral and Bilateral  Nasal (ON) breathing with maximal behavioral activation. The data from polygraphic electroencephalographic recordings from five healthy volunteers, before, during and after  exercise are presented in support of this physiological classification of LA arousal. On the basis of Limbic-Autonomic asymmetry a novel concept of ‘Visceral Dominance’ is also proposed. Douglas-Klotz, Neil. The natural breath: Towards

email: [email protected]. Abstract: Breathing is a vital behavior that is particularly amenable to experimental investigation. We review recent progress on three problems of broad interest. (i) Where and how is respiratory rhythm generated? The preBötzinger Complex is a critical site, whereas pacemaker neurons may not be essential. The possibility that coupled oscillators are involved is considered. (ii) What are the mechanisms that underlie the plasticity necessary for adaptive changes in breathing? Serotonin-dependent long-term facilitation following intermittent hypoxia is an important example of such plasticity, and a model that can account for this adaptive behavior is discussed. (iii) Where and how are the regulated variables CO2 and pH sensed? These sensors are essential if breathing is to be appropriate for metabolism. Neurons with appropriate chemosensitivity are spread throughout the brainstem; their individual properties and collective role are just  beginning to be understood. Feleky, A. The influence of the

Respiratory sinus arrhythmia is associated with efficiency of pulmonary gas exchange in healthy humans. American Journal of Physiology—Heart and Circulation Physiology, May 2003, 284(5):H1585-H1591 Abstract: Respiratory sinus arrhythmia (RSA) may be associated with improved efficiency of pulmonary gas exchange by matching ventilation to perfusion within each respiratory cycle. Respiration rate, tidal volume, minute ventilation (E), exhaled carbon dioxide (CO2), oxygen consumption (O2), and heart rate were measured in 10 healthy human volunteers during paced breathing to test the hypothesis that RSA contributes to  pulmonary gas exchange efficiency. Cross-spectral analysis of heart rate and respiration was computed to calculate RSA and the coherence and phase between these variables. Pulmonary gas exchange efficiency was measured as the average ventilatory equivalent of CO2 (E/CO2) and O2 (E/O2). Across subjects and paced breathing periods, RSA was significantly associated with CO2 (partial r = 0.53, P = 0.002) and O2 (partial r = 0.49, P = 0.005) exchange efficiency after controlling for the effects of age, respiration rate, tidal volume, and average heart rate. Phase between heart rate and respiration was significantly associated with CO2 exchange efficiency (partial r = 0.40, P = 0.03). These results are consistent with previous studies and further support the theory that RSA may improve the efficiency of pulmonary gas exchange. Goyeche, J. R. M., Y. Ago, and Y. Ikemi.

Breathing-control lowers blood pressure. Journal of Human Hypertension, Apr 2001, 15(4):263-269. PMID 11319675. Author email: [email protected]. Abstract: We hypothesize that routinely applied short sessions of slow and regular   breathing can lower blood pressure (BP). Using a new technology BIM (Breathe with Interactive Music), hypertensive patients were guided towards slow and regular   breathing. The present study evaluates the efficacy of the BIM in lowering BP. We studied 33 patients (23M/10F), aged 25-75 years, with uncontrolled BP. Patients were randomized into either active treatment with the BIM (n = 18) or a control treatment with a Walkman (n = 15). Treatment at home included either musically-guided breathing exercises with the BIM or listening to quiet music played by a Walkman for 10 min daily for 8 weeks. BP and heart rate were measured both at the clinic and at home with an Omron IC BP monitor. Clinic BP levels were measured at baseline, and after 4 and 8 weeks of treatment. Home BP measurements were taken daily, morning and evening, throughout the study. The two groups were matched by initial BP, age, gender, body mass index and medication status. The BP change at the clinic was -7.5/-4.0 mm Hg in the active treatment group, vs -2.9/-1.5 mm Hg in the control group (P = 0.001 for 

75

systolic BP). Analysis of home- measured data showed an average BP change of -5.0/-2.7 mm Hg in the active treatment group and -1.2/+0.9 mm Hg in the control group. Ten out of 18 (56%) were defined as responders in the active treatment group but only two out of  14 (14%) in the control group (P = 0.02). Thus, breathing exercise guided by the BIM device for 10 min daily is an effective non-pharmacological modality to reduce BP. Halámek, Josef, Tomás Kára, Pavel Jurák, Miroslav Soucek, Darrel P.

 phase shift between blood pressure and heart rate fluctuations: A marker of short-term circulation control. Circulation, 2003, 108:292. Author email: [email protected]. Abstract: Background: We postulated that the variability of the phase shift between blood  pressure and heart rate fluctuation near the frequency of 0.10 Hz might be useful in assessing autonomic circulatory control. Methods and Results: We tested this hypothesis in 4 groups of subjects: 28 young, healthy individuals; 13 elderly healthy individuals; 25  patients with coronary heart disease; and 19 patients with a planned or implanted cardioverter-defibrillator (ICD recipients). Data from 5 minutes of free breathing and at 2 different, controlled breathing frequencies (0.10 and 0.33 Hz) were used. Clear  differences ( P <0.001) in variabilityof phase were evident between the ICD recipients and all other groups. Furthermore, at a breathing frequency of 0.10 Hz, differences in  baroreflex sensitivity ( P <0.01) also became evident, eventhough these differences were not apparent at the 0.33-Hz breathing frequency. Conclusions: The frequency of 0.10 Hz represents a useful and potentially important one for controlled breathing, at which differences in blood pressure-RR interactions become evident. These interactions, whether computed as a variabilityof phase to define stability of the blood pressure-heart rate interaction or defined as the baroreflex sensitivity to define the gain in heart rate response to blood pressure changes, are significantly different in patients at risk for  sudden arrhythmic death. In young versus older healthy individuals, only baroreflexgain is different, with the variability of phase being similar in both groups. These measurements of short-term circulatory control might help in risk stratification for sudden cardiac death. Hanna, Thomas. Somatic Exercises™ for Full Breathing audiocassettes. Novato, Calif.:

Abstract: Guolin Qigong is a combination of meditation, controlled breathing and  physical movement designed to control the vital energy (qi) of the body and consequently to improve spiritual, physical, and mental health. Practice of Qigong has been reported to alter immunological function, but there have been few studies of its effects on cytokines, the key regulators of immunity. Numbers of peripheral blood cytokine-secreting cells were determined by ELISPOT in 19 healthy volunteers aged 27-55 before they were taught the practice of Qigong and after 3, 7 and 14 weeks of daily practice. The effect of  Qigong on blood cortisol was also examined. Numbers of IL4- and IL12-secreting cells remained stable. IL6 increased at 7 weeks and TNF; increased in unstimulated cultures and 3 and 7 weeks but decreased at these times in LPF and SAC-stimulated cultures. Of   particular interest, IFN-secreting cells increased and IL10-secreting cells decreased in PHA-stimulated cultures, resulting in significant increases in the IFN:IL10 ratio. Cortisol, a known inhibitor of type 1 cytokine production, was reduced by practicing Qigong. Jones, Philip.

Abstract: To examine the physiological effects of Korean traditional Qi-training, we investigated the changes in blood pressure, heart and respiratory rates before, during and after ChunDoSunBup (CDSB) Qi-training. Twelve normal healthy CDSB Qi-trainees (19-37 years old; trained for 1.3 +/- 0.2 years; 9 men and 3 women) volunteered to  participate in this study. Heart rate, respiratory rate, systolic blood pressure and rate pressure product were significantly decreased during Qi-training. From these results, we suggest that CDSB Qi-training has physiological effects that indicate stabilization of  cardiovascular system.

 Zealand Journal of Psychiatry, 1999, 33(2):197-206. Abstract: Objective: This review

article aims to explore current opinions on Qigonginduced mental disorders, an entity which is unfamiliar to Western psychiatrists. Method: Relevant literature published in Chinese and English is reviewed. Results: The review is divided into three sections: first, there is brief consideration of the historical development of Qigong in traditional Chinese medicine and its role in psychiatry; second, there is a review of the literature published on Qigong deviations and Qigong-induced mental disorders; and third, there is a discussion on the aetiological role of Qigong in these conditions. Conclusions: Qigong remained veiled in secrecy and available only to the elite until the early 1980s. Despite the widespread use of Qigong, there is a conspicuous lack of controlled data regarding its effects on mental health. Qigong, when practised inappropriately, may induce abnormal psychosomatic responses and even mental disorders. However, the ties between Qigong and mental disorders are manifold, and a causal relationship is difficult to establish. Many so-called “Qigong-induced psychoses” may be more appropriately labelled “Qigong-precipitated psychoses,” where the practice of Qigong acts as a stressor in vulnerable individuals. Nunn, J. F.

“After many years in Korea, I’m just beginning to break the Korean shell and experience its rich spiritual culture. Korea has much more to offer the world than kimchi and ‘the red devils.’ I’d like to introduce the world to the Korean form of meditation called ‘Seon-do’ Practice. It’s more than 5,000 years old and precedes Buddhism, Taoism, Confucianism and others. The focus is on the ‘living’ breath, which can only be found by focusing on the ‘Dan-jeon’ spot. Dan-jeon is known as ‘tan-tien’ in Chinese and ‘hara’ in Japanese. Yoga uses a chakra to describe the location but doesn’t use methods to store energy there: which is the main point of using the Dan-jeon, located five inches below the navel. “The essence of Seon-do practice is in concentrating on the breathing point, after having controlled your emotions, practiced muscles exercises, and lowered your consciousness. You’ll find that this is not mindfulness—but mindlessness. Masters throughout Asia have searched for correct Dan-jeon breathing, understanding that it’s the origin of all breathing techniques, but many have not had the patience or the correct teacher to learn it. Even now, we receive phone calls from monks from time to time asking how to do the  breathing method! “Meditation in the ‘lotus position’ is not emphasized until your breathing point has been found, and it takes six months of lying down breathing just to find the location . . .” Thoracic pressure and nasal patency. Journal of Applied Physiology, 1987, 62(1):91-94. PMID: 3558199 Singh, Virendra.

Abstract: Maximum nasal flow rate in the right and left nostrils was simultaneously determined during expiration with the help of two flowmeters in 10 healthy subjects in different postures and in two patients, one with Horner’s syndrome and the other with facial palsy. It was found that pressure on the hemithorax from any surface (i.e., lateral, anterior, posterior, or superior) leads to reduced patency of the ipsilateral nostril but increased patency of the nostril on the opposite site. In the patient with Horner’s syndrome, the nostril on the affected side rema ined blocked even on compression of the opposite hemithorax, and in the one with facial nerve palsy, the nostril on the affected side remained patent despite compression of the hemithorax on that side. The findings suggest that compression of hemithorax leads to changes in the congestion of the nasal

The relationship between nostril dominance and  preferred handedness. Poster presentation at St. Lawrence University Festival of Science, Canton, New York, Apr 2001. Stein, Emily,and Leah Brzuszkiewicz.

Abstract: The classic nasal cycle is a pattern where congestion on one side of the nose is accompanied by decongestion of the other side. Past studies have investigated various aspects of this biological occurrence, and great variability was found. Flanagan and Eccles (1997) and Fisher, Liu, and Lund (1994) reported that a nasal cycle was exhibited in approximately 80% of the population. However, others, such as Gilbert (1989) and Winkler, Combs, and Daley (1994) reported that only 20% of the population displayed these cyclic changes. In addition, different studies have reported huge differences (from 48 minutes to 7.3 hours) in the average length of the nasal cycle. A goal of the present study was to account for some of this large variability in nasal cycling behavior by considering a person’s preferred handedness. Since some studies have reported evidence that odorant sensitivity differs between the left and right nostril, and that this difference varied if a person was right-handed or left-handed (Hummel, Mohammadian & Kobal, 1998; Youngentob, Kurtz, Leopold, Mozell, Hornung (1982, but cf., Zatorre & JonesGotman, 1990), we hypothesized a relationship between handedness and nostril dominance. We tested 20 healthy males, 11 right-handed subjects (RH) and 9 left-handed subjects (LH). Nasal airflow was measured once every 15 minutes for a 6 hour period. The  participants were confined to three separate rooms, and monitored to ensure participation in only stationary activities. A nasal flowometer was constructed to measure the relative airflow of the two nostrils. Hot wire anemometers were secured in place on the apparatus and connected to a Mac Lab recording system. In order to obtain a reading, with their  mouths closed, the participants exhaled through their noses onto the anemometers. The  probes measured various aspects of nasal airflow such as maximum slope, maximum  peak, mean flow, and volume. Since all four of these measurements identified the same nostril as being dominant, maximum peak was chosen as the representative measure of  airflow. Following each nasal flowometer measurement, participants were asked to  provide a self-report concerning which nostril they thought was the one with the dominant airflow. Although LH were found to have more nasal cycle shifts than RH, based on both maximum peak and self-report, these differences were not significant. For LH, the left nostril was significantly more likely dominant, while the opposite was true for RH, for   both maximum peak and self-report. Self-report was not a very reliable measure when

compared with physiological measures of airflow. This study demonstrates for the first time a relationship between nostril dominance and handedness. Stevenson, I., and H. Ripley. Variations in

Alternating cerebral hemispheric activity and lateralization of autonomic nervous function.  Human Neurobiology, 1983, 2:39-43. PMID: 6874437. Abstract: Alternating dominance of cerebral hemispheric activity was demonstrated in humans by use of the electroencephalogram (EEG). Relative changes of electrocortical activity have a direct correlation with changes in the relative nostril dominance, the socalled nasal cycle. The nasal cycle is a phenomenon where efficiency of breathing alternates predominantly through right or left nostril with a periodicity ranging from 25 to greater than 200 minutes. Relatively greater integrated EEG value in one hemisphere correlates with predominant airflow in the contralateral nostril, defining a new interrelationship between cerebral dominance and peripheral autonomic nervous function.  ___________, R.

hemispheric stimulation by uninostril forced nostril breathing.  Human Neurobiology, 1987, 6:165171. PMID: 3449485. Abstract: We have previously demonstrated by the integration of EEG amplitudes, that an ultradian rhythm of alternating cerebral dominance exists in humans. This rhythm is tightly coupled with the nasal cycle, since its lateralization correlates with shifts in airflow through the left and right nostrils, where relatively greater integrated amplitudes in one hemisphere correspond to predominant airflow in the contralateral nostril. The nasal cycle is known to be regulated by the sympathetic and parasympathetic branches of  the autonomic nervous system. This dynamic lateralization of alternating activity in the

82

autonomic nervous system exists in other peripheral structures and is also likely to be the mode of regulation of the cortical rhythm. This paper shows that forced nostril breathing in one nostril produces a relative increase in the EEG amplitude in the contralateral hemisphere. This phenomena was demonstrated in 5 out of 5 untrained subjects. These results suggest the possibility of a non-invasive approach in the treatment of states of   psychopathology where lateralized cerebral dysfunction have been shown to occur. Westcott, M.

Conducting the following research project: Electrophysiological Correlates of Yoga Breathing Techniques

Various styles of breathing are promoted as beneficial. Inhalation and exhalation methods often differ widely, however, with various combinations of abdominal  &/or thoracic dominance being favored. Different rhythms of breathing, from hyperventilation to very-slow-rate, are used, often with various esoteric and/or  medical claims. Validation studies are few, particularly comparative studies of  more than one technique. While certain, specific breathing practices have been  studied so far that show differential effects on brain laterality and cardiac autonomic variations, no study to-date has described and cross-correlated the effects of the all the main, breathing techniques commonly promoted in yoga classes today. This project seeks to:

1. catalogue and describe the various breathing techniques available today using standard, anatomical, physiological, psychological and medical-terminologies. 2. explore the relationship between certain breathing techniques by measuring abdominal and thoracic inputs and their concomitant-effects on the brain, heart and autonomicnervous-system using electrophysiological recordings (EEG and ECG) on human subjects over time. 3. uncover functional brain and cardiac autonomic- nervous-system interactions using conscious, controlled, yoga-based, breathing techniques that may have relevance in  preventing and/or dealing with certain cardiac problems prevalent today. As certain types of breathing can profoundly impact on human physiology and  psychology, this study will help better understand the neurophysiological implications underpinning various yoga, meditation and relaxation techniques. It may even have relevance in non-pharmacological management of stress, hyp ertension, depression, stroke, cardiac problems, sleep disordered breathing and asthma. Equipment required to complete this study will include: EEG to give measures of localised, hemispherical brain-activity, which can be correlated with other ancillary measures of autonomic nervous activity such as lateralised nasalairflow and lateral peripheral-temperature. ECG to provide relative changes in heart rate variability. Cardiac parasympathetic and sympathetic activity can then be assessed using respiratory sinus arrhythmia (RSA) and  pre-ejection period (PEP). The cardiac system allows both parasympathetic and sympathetic activity to be reliably and concurrently estimated, with strong consensus in the literature identifying RSA and PEP as the most validated, non-invasive measures of  cardiac parasympathetic and sympathetic activity, respectively. Your participation would initially involve completing an online yoga and health-

questionnaire that takes around 15 minutes. Various volunteers in certain locations
