Study on the effects of lower body plyometrics and dynamic stretching on vertical jump in female collegiate volleyball players

Purpose: This study aimed to determine the effectiveness of plyometric training and plyometric exercises with dynamic stretching program on vertical jump height (VJH) in female student volleyball athletes. Materials and Methods: This randomized controlled study was performed for an 8-week period, with a total number of 90 female volleyball athletes ranging from the age group of between 18 and 22 years. The participants were randomly arranged as two experimental groups and one control group with 30 members in every group. All the participants were analyzed their vertical jump performance with Sargent jump test before starting the exercise training. The performance of VJH was reassessed at the end of every 2 weeks till the completion of training program. Results: The present study results showed a significant improvement on VJH at the end of every 2 weeks in both experimental groups. The maximum effect of VJH was noticed at the end of 8th weeks. The obtained effects of both experimental groups were significantly higher as compared to the control group (P < 0.05). However, the dynamic stretching with plyometric training group had a significantly better performance on VJH as compared to the experimental Group 1 (P < 0.05). Conclusion: This study results express that the dynamic stretching with plyometric exercises can be the more advantageous training program for a better vertical jump performance in female college student volleyball athletes.
