The study aims to investigate the regional plyometric trainings’ effects on the agility performance of male volleyball players. Süleyman Demirel University Volleyball Team with 20 players attended to the study voluntarily. Players were randomly divided into volleyball training group (VTG) (n = 10) and plyometric training group (PTG) (n = 10). As the VTG continued with their routine volleyball training; regional plyometric trainings for the lower extremity were performed to the PTG for 6 weeks, 3 days a week, at least 30 minutes a day in addition to volleyball training. T and Pro-Agility Tests were applied to the groups at the beginning and end of the 6-week period. Descriptive Statistics, Paired t-Test, and Independent t Test were used for comparison. “p<0.05” significance level was accepted for the results’ evaluation. Results of comparison of the T and Pro-Agility pre and post tests’ values of the groups, differences were statistically significant in PTG’s values p<0.05), but no differences were found in VTG’ values (p>0.05). Also, no differences were found as a result of the comparison of the pre and post T and Pro-Agility test values between the groups (p>0.05). Considering that plyometric trainings provide maximum contraction in the shortest time possible and its effect on the characteristics like sudden changes of location and direction in the volleyball, applying plyometric trainings may be thought to be effective in volleyball training programs.
