The purpose of this study was to examine the effects of jump squats and depth jumps on explosive power among volleyball players. Forty-five male collegiate volleyball players (age 17-22 years) were randomly assigned to three groups: Jump Squat Group (n = 15), Depth Jump Group (n = 15), and Control Group (n = 15). The experimental groups underwent their respective plyometric training programs for 12 weeks, while the control group did not participate in any specialized training. Pre- and post-tests on explosive power were conducted, and data were analyzed using ANCOVA at a 0.05 level of significance. The results revealed significant improvements in explosive power for both the Jump Squat Group (pre-test mean = 1.31, post-test mean = 1.44, adjusted post-test mean = 1.42) and the Depth Jump Group (pre-test mean = 1.24, post-test mean = 1.36, adjusted post-test mean = 1.40) compared to the Control Group (pre-test mean = 1.33, post-test mean = 1.34, adjusted post-test mean = 1.31). Post hoc analysis using Scheffe's test indicated significant differences between Jump Squat and Control groups (MD = 0.11), Depth Jump and Control groups (MD = 0.09), while no significant difference was observed between the two experimental groups (MD = 0.02). The study concludes that both jump squats and depth jumps are effective plyometric training methods for enhancing explosive power in volleyball players. These exercises can be incorporated interchangeably or complementarily into training programs to improve vertical jump performance, neuromuscular coordination, and on-court performance.
