A comparison of the effects of plyometric and resistance power training programs on physical performance of volleyball players

Objective: Different training methods can affect the athletes’ physical performance in different ways. The purpose of present study was to compare the effects of plyometric and resistance power training programs on physical performance of volleyball players.
Methods: Twenty-seven male players of a local team in Esfarayen, Iran, volunteered. The participants were randomly assigned into two groups; polymetric (n=13) and resistance power training (n=14). Training period lasted 6 weeks, 3 days per week. Physical performance included vertical jump, spike jump, agility, sprint (9 and 18 meters) and repeated effort test for volleyball was measured before training programs and 48 hours after the last session through special tests. Data were analyzed using shapiro-wilk, paired and independent samples t-tests at the level of 0.05.
Results: Results showed that both training methods can increase vertical jump, spike jump, agility, sprint (9 & 18 m) and repeated effort test for volleyball (ideal time, actual time, ideal jump, actual jump) in volleyball players (P
