These exercises are performed to improve muscular activities ( 2). Plyometric exercises are among the most common techniques in volleyball trainings ( 1). Lower body explosive power performance is an essential part of many athletic activities, especially for the vertical jumps in volleyball. However, combined training of lower body plyometrics and lower limbs dynamic stretching had better results in terms of vertical jump performance. Compared to females, male participants had a better improvement of VJH in both training groups (p<0.05).Ĭonclusion: It can be concluded that two sessions of plyometric exercise training per week for eight weeks can improve the ability of VJH in male and female collegiate volleyball players. The effect of training was significantly higher in male and female groups who have performed plyometrics with lower limbs dynamic stretching as compared with the groups that performed only plyometric exercises (p<0.05). However, the control groups did not display any improvement. Results: Plyometrics and plyometrics with dynamic stretching led to significant improvements in vertical jump height (VJH), and this improvement was progressed after every two weeks of training. All the participants underwent Sargent vertical jump performance test before starting the training session it was repeated in every two weeks of training program. They were randomly distributed into three male groups (Group 1, Group 2 & Group 3) and three female groups (Group 4, Group 5 & Group 6) with 30 participants in each group. All the participants were recreational players and they were playing one hour daily in the evening. The total number of participants was 90 male and 90 female collegiate volleyball players aged 18-22 years. Materials and Methods: The study was carried out as two training sessions in a week, for eight weeks duration. Objective: Aim of this study was to investigate the combined and comparative training outcomes of plyometrics and dynamic stretching of lower limb muscle groups on vertical jump performance in male and female collegiate volleyball players.
