ANALYZING THE EFFECT OF POST ACTIVATION POTENTIATION ON VERTICAL JUMP HEIGHT IN VOLLEYBALL PLAYERS

The aim of the study was to find the effect of post activation potentiation (PAP) on jump performance in volleyball players and to compare its effects between males and females. Forty volleyball players were randomly divided into control and experimental group. The experimental group performed a PAP protocol consisting of 3 sets of 10 repetitions at 50% of 10 RM, 75% of 10 RM, 100% of 10 RM (repetition maximum) back squats. At the end of the last set of squats subjects performed 3 successive vertical jumps. Control group subjects performed only warm up for 10 minutes prior to assessment of jump performance. Results showed highly significant difference (p=0.0002) between the pre and post values of vertical jump height in males and significant difference (p=0.0008) in females. The findings of the present study also vivid that there were statistically significant difference (p=0.0130) between the post values of vertical jump height in males as compared to females. This study illustrate that stronger athletes have a greater potentiation, which is due to an ability to become more fatigue resistant as strength level increase and post-activation potentiation effect shows enhancement of on jump performance in volleyball players. This protocol might be helpful for the athletes as well as athletic trainers, coaches to formulate an effective training protocol for the athlete who will enhance their acute performance
