The Effect Of Plyometric Training On The Improvement Of Leg Muscle Power In The Futsal Extracurricular Program At Sman 5 Bandar Lampung

Abstract

This study aims to determine the effect of plyometric training on increasing leg muscle power among futsal extracurricular students at SMAN 5 Bandar Lampung. This research employed an experimental method using a pretest-posttest control group design. The sample consisted of 22 students divided into two groups: an experimental group that received plyometric training and a control group that did not receive any treatment. The instrument used to measure leg muscle power was the Standing Broad Jump test. The data analysis showed a significant improvement in the post-test results of the experimental group compared to the control group. This finding is supported by statistical analysis, which showed a t-value of 4.060, greater than the t-table value of 2.086. Therefore, it can be concluded that plyometric training has a significant effect on increasing leg muscle power in futsal extracurricular students. This training is recommended as an effective method for physical development in school sports extracurricular activities.
