RESUMEN
Both Physical exercises and yogasanas are accepted by people to remain fit. The present study is conducted to find out the efficacy of the practice in human beings by comparing the cardio-respiratory parameters with that of subjects not performing any of these two. 30 male age, height and weight matched subjects were selected in each group viz. Control, Exercise and Yoga groups. Their Cardio-respiratory parameters were taken and compared between the groups. The results showed decrease in Pulse rate, Systolic as well as Diastolic blood pressure, and respiratory rate in subjects of exercise and yoga groups compared to that of control group. Significant increase in Respiratory capacities, % of Forced expiratory volume in 1st second, Maximum expiratory pressure and Peak expiratory flow rate are seen in both the groups. The results showed reduction in Respiratory minute volume significantly more in yoga group compared to exercise group while increase in Inspiratory capacity is significantly more in exercise group compared to yoga group.
