Effect of Plyometric Training and Body Weight Training on Volleyball Player's Leg Muscle Power

Background: Attacking and defending along with jumping aggressively are needed by volleyball players. Methods to increase leg muscle power include bodyweight training and plyometrics. However, the application of this method is limited to knowing the effect of one model only, and previous studies claimed that the jump height as power means that it is not suitable. Important aspects such as training dosage settings, and exercise variations still need further research. The purpose of the study was to determine the effect of body weight training and plyometrics on leg muscle power. Materials and Methods: The research method used in this study was experimental with a pretest-posttest control design. The participants of this study were male volleyball players aged 16-17 years totaling 30 people, who were selected by purposive sampling. The research instrument used was the vertical jump test. Data collection techniques include field tests, analysis of relevant articles, and observation. Data analysis was carried out using the Harman formula to determine power, assisted by Excel. Furthermore, the results of the study were analyzed using the Kruskal-Wallis formula with the help of SPSS version 23. Results: Peak power was found to have a significance value of 0.002<0.05, the difference between mean body weight and plyometrics was 404.11, and the mean difference between the control group and plyometrics was 229.16. Conclusions: The plyometrics method group was better than the control group and body weight training group on increasing peak power on the leg muscle power of young volleyball players.
