The aim of the study was to determine whether there was a substantial enhancement in the efficiency of physiological and biochemical variables as a result of specific asanas and interval training. In the execution of this inquiry, the researcher utilized a random sampling method. The research encompassed a total sample of ninety boys selected at random from a pool of 150 students attending Shri Navdurga High School, Rajpipla, Narmada District, Gujarat, with ages ranging from 12 to 15 years. The research design employed pre- and post-tests in conjunction with an analysis of covariance technique. The practice of yogic asanas and interval training demonstrated a significant improvement in pulse rate, breath-holding duration, and vital capacity. When comparing Experimental Group-I (yogic asanas) with the Control Group, there was a notable improvement in pulse rate, vital capacity, and breath-holding duration. Likewise, a significant improvement in these parameters was observed when comparing Experimental Group-II (interval training) with the Control Group. However, when the physiological variables of Experimental Group-I were compared with those of Experimental Group-II, no significant difference was found in the case of Experimental Group-I, whereas Experimental Group-II exhibited a significant difference in physiological variables. The study suggests that similar investigations should be undertaken for different age groups of males.
