KOMBINASI STATIC STRETCHING DAN PLYOMETRIC TRAINING LEBIH BAIK DARIPADA KOMBINASI STATIC STRETCHING DAN STRENGTH TRAINING DALAM MENINGKATKAN VERTICAL JUMP PADA PEMAIN VOLI

Abstract

Background: Vertical jump is an essential component in jump smashes and service skills in volleyball games. The efficiency of the jump or explosive power of the lower limb can support the Sport and Fitness Journal E-ISSN: 2654-9182 Volume 9, No.1, Januari 2021: 29-33 30 player to score. Aim: to prove that the combination of static stretching and plyometric training is better than the combination of static stretching and strength training in increasing vertical jumps performance in volleyball players. Method: This was experimental study with randomized pre-test and post-test two group design. Participants for this study was collegiate volleyball player of STIKES Ngudia Husada Madura. Eighteen collegiate participate in this study and randomly divided into 2 groups with each group consist of 9 people. Group I was given a combination of static stretching and strength training while Group II was given a combination of static stretching and plyometric training. The treatment done 3 times a week for 6 weeks with evaluation using the sargent jump test (SJT). Result: Statistical analysis using paired-samples t-test in Group I revealed a mean score before intervention 38.78 ± 3.52 cm and after the intervention is 48.89 ± 6.09 cm with p value = 0.001. While in Group II mean scores before intervention 37, 11 ± 4.01 cm and after the intervention 54.11 ± 2.66 cm with p value <0.001. These results indicate that in each group there was a significant increase in vertical jump performance. Hypothesis different test between Group I and Group II using the independent-samples t-test obtained p value = 0.021. Conclusion: The combination of static stretching and plyometric training is better than the combination of static stretching and strength training at increasing vertical jumps performance in volleyball players.
