A Comparison of the Effect of Accelerated Plyometric, Resisted Plyometric and Common Plyometric Training on Power Performance, Strength and Muscle Hypertrophy in Active Males

The purpose of this study was to compare the effects of accelerated plyometric, resisted plyometric, and common plyometric training on power performance, strength and muscle hypertrophy. Thirty active males (age 20.67±1.12, height 174.83± 4.69, weight 63.45± 7.51) volunteered to participate in this study. The participants were randomly divided among three groups and were matched according to the amount of activity in a week and maximal strength. The training protocol consisted of four weeks with three sessions per week. The posttest was performed after 48 hours of the last session. Intergroup differences were analyzed with ANCOVA and LSD post hoc tests, and intragroup difference analyzed with paired t-test. The findings of the present study indicated that all three plyometric training (accelerated, resisted and common) were significantly improved compared with pretest in squat jump, countermovement jump and depth jump height, countermovement jumping peak and average power, maximal strength and anthropometrically thigh muscle cross-sectional area. Resisted plyometric training was leads to significant improvements in depth jump height compared with accelerate and common plyometric training. In addition, accelerate and resisted plyometric training were significantly an improvement in maximal strength than common plyometric training regards to results and change percent, it seems use of elastic bands in plyometric training (accelerated and resisted) more beneficial than common plyometric training. Furthermore, accelerated plyometric is more efficient in improvement of power and muscular strength than the resisted and common plyometric training.
