The Effect Of Split Squat Jump And Tuck Jump With Heel Kick Training On Leg Muscle Power Among LMVC Labuapi Volleyball Players

Abstract

Objectives: This study aimed to determine the effect of split squat jump and tuck jump with heel kick training on increasing leg muscle power among LMVC Labuapi volleyball players.

Materials and Methods: This study used an experimental method with a pretest-posttest design. The sample consisted of 22 LMVC Labuapi volleyball players, divided into two groups. Group A received split squat jump training, while Group B received tuck jump with heel kick training. Leg muscle power was measured using the vertical jump test before and after the training program. The data were analyzed using normality tests, homogeneity tests, paired sample t-tests, and independent t-tests.

Results: The results showed that split squat jump training significantly improved vertical jump performance, with a significance value of p = 0.007. Tuck jump with heel kick training also significantly improved vertical jump performance, with a significance value of p = 0.000. However, the comparison between the two groups showed no significant difference, with p = 0.281. These findings indicate that both plyometric training methods are effective for improving leg muscle power.

Conclusions: Split squat jump and tuck jump with heel kick training significantly increased leg muscle power among LMVC Labuapi volleyball players. Although tuck jump with heel kick showed a higher average improvement, the difference between the two training methods was not statistically significant. Therefore, both exercises can be used as alternative plyometric training programs to improve jumping ability in volleyball players.
