A STUDY ON THE EFFECT OF PHYSICAL EXERCISES AND YOGA ASANAS ON LEG EXPLOSIVE POWER AMONG JUNIOR COLLEGE VOLLEYBALL PLAYERS

Abstract

The purpose of this study was to investigate the effect of physical exercises and yoga asanas combined with physical exercises on leg explosive power among junior college volleyball players. Sixty male volleyball players aged between 16 and 18 years from junior colleges in Visakhapatnam District were randomly selected as subjects. The subjects were divided into three equal groups of twenty each: Physical Exercise Group (PEG), Yogic Practice Combined with Physical Exercise Group (YPCPEG), and Control Group (CG). The experimental groups underwent their respective training programmes, while the control group did not receive any special training. Leg explosive power was selected as the dependent variable and measured through pre-test and post-test scores. The pre-test mean values of leg explosive power for PEG, YPCPEG, and CG were 1.4776, 1.4526, and 1.4596 respectively, and the obtained F-ratio of 0.036 was not significant at the 0.05 level of confidence. The post-test mean values were 1.5421, 1.5536, and 1.4731 respectively, with an obtained F-ratio of 5.605, which was significant at the 0.05 level. The adjusted post-test mean values were 1.542, 1.558, and 1.472 respectively, and the obtained F-ratio of 22.158 was also significant. Scheffe’s post hoc test revealed significant mean differences between PEG and CG (0.07) and between YPCPEG and CG (0.086), while the difference between PEG and YPCPEG (0.02) was not significant. The findings of the study concluded that both physical exercises and yoga asanas combined with physical exercises significantly improved leg explosive power among junior college volleyball players. However, both experimental treatments were found to be equally effective.
