Abstract: This study was designed to investigate the Effect of plyometric training on selected physical and physiological variables among college Volleyball players. To achieve the purpose of the study 30 inter-collegiate male Volleyball players were selected from affiliated colleges of Bharathiar University, Coimbatore. The subjects was randomly assigned to two equal groups (n=15). Group- I underwent plyometric training (PTG) and Group - II was acted as control group (CG). The plyometric training was given to the experimental group for 3 days per week (Monday, Wednesday and Friday) for the period of twelve weeks. The control group was not given any sort of training except their routine work. A pilot study was conducted to assess the initial capacity of the subjects in order to fix the load. The physical parameters of speed (50 mts dash), leg explosive power (vertical jump) and physiological parameters (Breath Holding Time, Resting Heart Rate) before and after training period. The data collected from the subjects was statistically analyzed with ‘t’ test to find out significant improvement if any at 0.05 level of confidence. The result of the speed, leg explosive power and Breath Holding Time, Resting Heart Rate speculated significant improvement due to influence of plyometric training with the limitations of (diet, climate, life style) status and previous training. The result of the present study coincide findings of the investigation done by different experts in the field of sports sciences. Plyometric training group significantly improved speed, leg explosive power and Breath Holding Time, Resting Heart Rate college male Volleyball players.
