Immediate Effect of a Short-Duration Plyometric Protocol on Vertical Jump Height and Agility in Collegiate Volleyball Players

Background: Volleyball demands explosive power and agility. Plyometric training develops these qualities, but its immediate effects need further study.
Aim: To evaluate the immediate effect of a short-duration plyometric protocol on vertical jump height and agility in collegiate volleyball players.
Methods: Study Design: Experimental Study, Study Setting: Department of Physical Education, Annamalai University, Sample Size: 15-20, Participants: Collegiate Volleyball Players aged 18-25 years,
Sampling type: Convenience Sampling, Procedure: Baseline measurements of vertical jump height and Agility were recorded. After the protocol had been performed, post-test measurements were taken immediately. Data were analyzed using a paired t-test (p<0.05).
Results: The results demonstrated a statistically significant improvement in both performance variables, the mean vertical jump height (42.3 ± 4.5cm to 45.8 ± 4.2cm) and agility (17.2 ± 1.1s to 16.4 ± 1.0s) following the plyometric intervention(p<0.05).
Conclusion: Short-duration plyometric exercise significantly improves vertical jump height and agility in collegiate volleyball players. It can be effectively used as a warm-up strategy to enhance immediate performance.
