This study was to find out the combined and isolated effect of asanas and pranayama practices on expiratory reserve volume among obese men. To achieve this purpose of the study sixty obese men selected from in and around Malappuram, Kerala and their ages ranged between 17-25 years will be selected as subjects. The selected subjects will be divided into four equal groups, in which, Group I (N 15) will undergo asana practices, Group II (N 15) will undergo pranayama practices, Group III (N 15) will undergo asana and pranayama practices and Group IV (N 15) will act as control which does not participate in any special training. The training programme will be carried out for this study is three days per week for twelve weeks. The subjects were tested on expiratory reserve volume before and after the training period. Before the training period, expiratory reserve volumes were measured by using a wet spirometer. Analysis of Covariance (ANCOVA) was applied as a statistical tool for the present study. The Scheffé S test was used as a posthoc test at whatever point the ‘F’ – the ratio of the adjusted post-test means was discovered to be significant at 0.05 level of significance. Both asana, pranayama and asanas with pranayama practices group influence expiratory reserve volume when compared with the control group. Asana with pranayama practices may have a better influence on the expiratory reserve volume of obese men.
