METHODS: Cardiovascular responses to exercise were determined by the Harvard step test where subjects were asked to step up and down the platform at a rate of 30/min for a total duration of 5 min or until fatigue. Heart rate (HR) and blood pressure response to exercise were measured in the supine position before exercise and for several minutes after the exercise. RESULTS: Exercise increased HR and blood systolic pressure and a decreased diastolic pressure. After two months of yoga exercise-induced changes in these parameters were reduced.

METHODS: This study determined whether yoga reduced heart rate and whether the reduction would be more after 30 days of yoga training. Yoga and control groups were assessed on Day 1 and on Day 30. During the intervening 30 days, the yoga group received training in yoga techniques. At each assessment the baseline heart rate was recorded for one minute. This was followed by a six-minute period during which participants were asked to attempt to voluntarily reduce their heart rate, using any strategy. RESULTS: Both the baseline heart rate and the lowest heart rate achieved voluntarily during the six-minute period were lower in the yoga group on Day 30 compared to Day 1 by a group average of 10.7 beats per minute (i.e., bpm) and 6.8 bpm, respectively.

METHODS: The immediate effects of relaxation therapy (RT) were assessed in hospitalized children and adolescents with diagnoses of adjustment disorder and depression. These effects were assessed using a within subjects pre-test/post-test design and by comparison with a control group of  depressed and adjustment disorder patients who watched a 1-h relaxing videotape. The 1-h RT class consisted of yoga exercise, a brief massage and progressive muscle relaxation. RESULTS: Decreases were noted in both self-reported anxiety and in anxious behavior and fidgeting as well as increases in positive affect in the RT group. In addition, adjustment disorder patients and a third of the depressed patients showed decreases in cortisol levels following RT. Thus, both diagnostic groups appeared to benefit from the RT class.

Patel, C. and North, W. R. (1975). Randomized controlled trial of yoga and bio-feedback in management of hypertension. Lancet, 2, 93-95.

METHODS: Hypertensive patients were assigned at random either to six weeks of yoga methods with biofeedback or to general relaxation. RESULTS: Both groups showed a reduction in blood-pressure, although the decrease was significantly greater for the yoga group. The control group was then trained in yoga relaxation and their blood-pressure fell to that of the other group (now used as controls).

Khalsa, S.B. (2004). Treatment of chronic insomnia with yoga: a preliminary study with sleep-wake diaries. Applied Psychophysiology and Biofeedback, 29, 269-278.

METHODS: A simple daily yoga treatment was evaluated in a chronic insomnia population consisting of sleep-onset and/or sleep-maintenance insomnia and primary or secondary insomnia. Participants maintained sleep-wake diaries during a pretreatment 2-week baseline and a subsequent 8-week intervention, in which they practiced the treatment on their own following a single in-person training session with subsequent brief in-person and telephone follow-ups. RESULTS: Improvements were noted in sleep efficiency, total sleep time, total wake time, sleep onset latency, wake time after sleep onset, number of awakenings, and sleep quality measures based on sleep-wake diary entries.

METHODS : This study assessed whether chemoreflex sensitivity could be affected by the practice of yoga, and whether it was specifically because of a slow breathing rate obtained during yoga or as a general consequence of yoga. RESULTS: Slow breathing rate per se substantially reduced chemoreflex sensitivity, but long-term yoga practice was responsible for a generalized reduction in chemoreflex.


Malhotra, V., et al. (2002).Study of yoga asanas in assessment of pulmonary function in NIDDM patients. Indian Journal of Physiological & Pharmacology, 46, 13-20.

Visweswaraiah, N. & Telles, S. (2004). Randomized trial of yoga as a complementary therapy for pulmonary tuberculosis. Respirology, 9, 96-101.

METHODS: Pulmonary tuberculosis patients were allocated to yoga or breathing awareness groups. RESULTS: At the end of 2 months, the yoga group showed a significant reduction in symptom scores, and an increase in weight, and improved pulmonary function. Improved level of infection, radiographic picture, and FVC, and the weight gain and reduced symptoms in the yoga group suggest a complementary role for yoga in the management of pulmonary tuberculosis.



Khalsa, S.B. (2004). Yoga as a therapeutic intervention: A bibliometric analysis of published research studies. Indian Journal Physiology and Pharmacology, 48, 269-85.

REVIEW: Although yoga is historically a spiritual discipline, it has also been used clinically as a therapeutic intervention. A bibliometric analysis on the biomedical journal literature involving research on the clinical application of yoga has revealed an increase in publication frequency over the past 3 decades with a substantial and growing use of randomized controlled trials. Types of medical conditions have included psychopathological (e.g. depression, anxiety), cardiovascular (e.g. hypertension, heart disease), respiratory (e.g. asthma), diabetes and a variety of others. A majority of this research has been conducted by Indian investigators and published in Indian journals, particularly yoga specialty journals, although recent trends indicate increasing contributions from investigators in the U.S. and England. Yoga therapy is a relatively novel and emerging clinical discipline within the broad category of mind-body medicine, whose growth is consistent with the burgeoning popularity of yoga in the West and the increasing worldwide use of alternative medicine.

The yoga group received training postures, breathing maintenance of silence, as well as visual focusing exercises and games to improve their attention span and memory. RESULTS: After 10 days, the 'Yoga' group showed a significant improvement.
