Background: The Pulmonary Function Tests are important for measuring the fitness of an individual from a physiological point of view. Lung function parameters tend to have a relationship with lifestyle such as regular yoga, an ancient system of Indian Philosophy. Yoga is probably the best lifestyle ever devised in the history of mankind. Hence the present analytical study was undertaken to assess the effects of yoga on respiratory system when compared with sedentary subjects. Objective: To compare the pulmonary function test among the yogic and sedentary groups. Materials and Methods: The present study was conducted on 50 subjects practicing yoga and 50 sedentary subjects in the age group of 20-40 years. They were assessed for pulmonary function test in which sedentary group acted as controls. The tests which were recorded as per standard procedure using Medspiror as determinants of pulmonary function were FVC, FEV1, FEV3, PEFR and FVC/FEV1 ratio. Results: Pulmonary Functions were compared between the yoga practitioners and sedentary group. Yoga exercise significantly increased chest wall expansion as observed by higher values of pulmonary functions compared with sedentary controls. The study group were having higher mean of percentage value of FVC 109.1 ± 18.2%, FEV1 of 116.3 ± 15.9%, FEV3 of 105.7 ± 14.9 %, PEFR of 109.2 ± 21.3% and FEV1/FVC ratio of 111.3 ± 6.9% as compared to sedentary group. Conclusions: Regular Yoga practice increases the vital capacity, timed vital capacity, maximum voluntary ventilation, breath holding time and maximal inspiratory and expiratory pressures.
