title: An evaluation of pulmonary parameters in two groups of subjects during Yoga practice.
abstract: The purpose of the present study was to investigate how far the short term practice of yoga (30 and 60 days) for an hour daily can improve the respiratory function. Male subjects (n=50, age 30-50 years) were randomly selected. Respiratory parameters (FVC, FEV1, PEFR, FEF(25-75%) and MVV) were determined by using a multifunctional computerized spirometer. Yoga (posture and pranayamas) practice for a month produced no significant improvement in pulmonary parameters. Nevertheless, when the subjects continued it for next 30 days, i.e., after 60 days significant changes were noted in FVC (p<0.001), FEV, (p<0.01) and PEFR (p<0.05). The result also revealed that amongst them 30 days yoga training resulted in a significant increase in FVC in elder group of people (age 41-50 yrs) where as in younger group (age 30-40 yrs) the changes were not so prominent. Result indicated that short term (30 days) yoga practice quickly improves respiratory functions in relatively elder people (age 41-50 yrs), when many of them in our tropical country suffer from primary level of respiratory problem. Regular practice of Yoga (posture and pranayamas) can prevent it by increasing the efficacy of respiratory muscles.
