Clinical study of yoga techniques in university students with asthma: a controlled study.

Adult asthmatics, ranging from 19 to 52 years from an asthma and allergy clinic in a university setting volunteered to participate in the study. The 17 students were randomly divided into yoga (9 subjects) and nonyoga control (8 subjects) groups. The yoga group was taught a set of breathing and relaxation techniques including breath slowing exercises (pranayama), physical postures (yogasanas), and meditation. Yoga techniques were taught at the university health center, three times a week for 16 weeks. All the subjects in both groups maintained daily symptom and medication diaries, collected A.M. and P.M. peak flow readings, and completed weekly questionnaires. Spirometry was performed on each subject every week. Analysis of the data showed that the subjects in the yoga group reported a significant degree of relaxation, positive attitude, and better yoga exercise tolerance. There was also a tendency toward lesser usage of beta adrenergic inhalers. The pulmonary functions did not vary significantly between yoga and control groups. Yoga techniques seem beneficial as an adjunct to the medical management of asthma.

Parks and golf course workers.

Most of the work done by parks and golf course workers is performed outside, and they are subject to risks similar to those of other outdoor workers, such as temperature and weather-related problems, infectious diseases, and poisonous plants, snakes, and spiders. They are also exposed to physical hazards related to noise and operation of heavy equipment. Chemical hazards result from use of pesticides and solvents. This chapter reviews pertinent OSHA regulations, pre-placement strategies, and medical surveillance exams, and recommends preventive programs. More research is needed to determine specific hazards and work-related injury and illness rates for parks and golf course workers, so that effective preventive programs can be designed.
