The Effect of Depth Jump Training and Single Leg Bound Training on Increasing Leg Muscle Power of Male Athletes at Tapak Suci Tarbiyah Deli Serdang School in 2025

This study was motivated by the lack of leg muscle power ability of athletes, resulting in weak kicks. This study aims to determine whether there is an effect of depth jump and single-leg bound training on increasing leg muscle power of male athletes at Tapak Suci Tarbiyah School, Deli Serdang Regency. This study uses an experimental method with a one-group pre-test post-test design. The population in this study were male athletes at Tapak Suci Tarbiyah School, Deli Serdang, totalling 10 people. The research sampling technique used was purposive sampling. Purposive sampling is a sampling technique with several considerations. In this study, the sample was 8 athletes. The data collection technique used was by taking a pre-test, treatment and post-test. From the analysis of vertical jump data that has been carried out, it is known that the t_count hypothesis value is obtained at 21.531 and t_table 1.894, then (t_count 21.531> t_table 1.894), so that there is an effect of depth jump training and single leg bound training on increasing the leg muscle power of male athletes at the Tapak Suci Tarbiyah Deli Serdang School in 2025. The novelty of this study lies in the combination of depth jump and single-leg bound training in one structured training program aimed at increasing the leg muscle power of pencak silat athletes, which has not been widely studied, especially in athletes at the Tapak Suci Tarbiyah Deli Serdang School.
