Voluntary control of breathing pattern in asthmatic children

Breathing retraining for asthma

Breathing retraining is used increasingly throughout the world by many patients with asthma in addition to their usual medical care. We undertook a systematic review of the literature in order to determine the effectiveness of breathing retraining in the management of asthma. Six randomised-controlled trials were identified that involved breathing retraining in asthma. Due to the variation in reported trial outcomes, limited reporting of study data and small number of included trials it was not possible to draw any firm conclusions as to its effectiveness. However, outcomes that were reported from individual trials do show that breathing retraining may have a role in the treatment and management of asthma. Further large-scale trials using breathing retraining techniques in asthma are required to address this important issue.

Psychophysiologic effects of Hatha Yoga on musculoskeletal and cardiopulmonary function: a literature review

Yoga has become increasingly popular in Western cultures as a means of exercise and fitness training; however, it is still depicted as trendy as evidenced by an April 2001 Time magazine cover story on "The Power of Yoga." There is a need to have yoga better recognized by the health care community as a complement to conventional medical care. Over the last 10 years, a growing number of research studies have shown that the practice of Hatha Yoga can improve strength and flexibility, and may help control such physiological variables as blood pressure, respiration and heart rate, and metabolic rate to improve overall exercise capacity. This review presents a summary of medically substantiated information about the health benefits of yoga for healthy people and for people compromised by musculoskeletal and cardiopulmonary disease.
