The Effect of Plyometric Methods on Increasing Leg Power in Sprint Athletes

Abstract

This research aims to determine the effect of Plyometric Training on Increasing the Limb Power of Sprint Athletes. This research is based on the author's interest in plyometric exercises to apply to the 12-16 year age group, and looking at the population in applying research on leg power using plyometric exercises. The research method used is an experiment with a one group pretest-posttest research design. The population in this study were all athletic extracurricular participants of SMPN 1 SUKAWANGI who attended the athletic sports club (Sukawangi Athletics Club). Sampling in this study using saturated sampling technique, namely all members of the population were used as samples totaling 16 people. The instrument used in this study was the Standing Broad Jump Test. The data collection technique was carried out by giving an initial test before being given the treatment of a plyometric exercise program and the final test was given after the treatment of a plyometric exercise program. Data processing techniques were carried out with descriptive statistical analysis and correlation tests using SPSS version 15. Based on the results of the correlation test of the results of plyometric training from the initial test to the final test, it was found that plyometric training can significantly increase leg power.
