The purpose of this study was to examine the plyometric training–induced changes in selected physical, physiological, and skill performance variables among volleyball players. A total of 40 volleyball players were randomly selected and divided into two equal groups: Group I served as the Plyometric Training Group (PTG), and Group II served as the Control Group (CG). The PTG underwent plyometric training three days per week for a period of twelve weeks, while the CG continued their routine activities without any additional training. A pilot study was conducted to determine the initial capacity of the subjects and to establish appropriate training loads. The selected physical variables included arm explosive power and leg explosive power; the physiological variable was breath-holding time, and the skill performance variable was spiking ability. These variables were measured before and after the twelve-week training period. Statistical analysis was performed using the t-test to determine the significance of the differences between the pre-test and post-test scores at the 0.05 level of confidence. The results revealed significant improvements in arm explosive power, leg explosive power, breath-holding time, and spiking ability among the participants in the plyometric training group. The findings indicate that plyometric training significantly improves selected physical, physiological, and skill performance variables among volleyball players. These results are consistent with previous research in the field of sports sciences, highlighting the effectiveness of plyometric training in enhancing volleyball performance.
