Comparison of the Effect of Two Types of Resistance Training Plyometric, and Traband on the Physical Performance of Young Volleyball Players

Introduction & Objective:

Resistance training plays an important role in increasing the physical performance of players in various sports. Accordingly, the aim of this study was to investigate and compare the effects of plyometric and traband resistance training on the physical performance of volleyball players.

This research was a quasi-experimental study with pre-test and post-test design and was conducted in a field method. Thirty young volleyball players of Shahid Bagheri Sports Complex in Tehran, ranging in age from 18 to 25 years old, were selected through purposive sampling and randomly divided into two groups of plyometric and traband resistance training. The training protocol was performed for 8 weeks, three sessions per week and 90 minute per session Subjects of both groups performed physical function tests including: vertical jump, smash jump, agility, displacement speed and functional test before and after the intervention. The collected data were analyzed using analysis of covariance at the significance level (P <0,05).

The results showed a statistically significant increase in physical performance indices including: vertical jump, spike jump, agility, displacement speed and combined functional test (ideal time, real time, ideal jump and real jump). There was no significant difference between the two groups in any of the above indicators. Only at the ideal time was a significant difference observed between the groups

The general conclusion is that both plyometric and traband resistance training exercises are effective in increasing the physical performance of volleyball players and can be used in combination with coaches and athletes.
