Abstract:
The purpose of this investigation was to find out the influence of plyometric training with and without weighted vest on speed and agility among college male volleyball players. Forty-five college male volleyball players (N = 45) were randomly selected as subjects and their age ranged between 18 and 22 years. The selected subjects were randomly assigned into three equal groups. Group I plyometric training with weighted vest (PTWWV), Group II plyometric training without weighted vest (PTWOWV), Group III control group (CG) and each group comprised of fifteen subjects (N = 15). Both the experimental groups underwent their respective experimental treatment for twelve weeks, 3 days per week and one session on respected days. Control group was not exposed to any specific training. Speed and agility were taken as variables for this study and was measured by 50m dash and shuttle run respectively. The collected data were analysed using analysis of covariance (ANCOVA) and Scheffe’s post hoc test. The results revealed significant difference in all the selected physical variables (p < 0.05) among PTWWV and PTWOWV pointing towards the use of plyometric training for performance improvement.
