PENGARUH LATIHAN PLYOMETRICS TERHADAP POWER OTOT TUNGKAI PADA ATLET BOLA VOLI KLUB DESA KOTA RAYA

Abstract

This research was motivated by several problems that researchers encountered in the field, namely the weak physical condition of this athlete seen when the athlete smashed the resulting jump that was not high enough so that the ball was not optimal when smashed. The purpose of this study was to determine whether there was an effect of plyometric training on leg muscle power in volleyball athletes at the Kota Raya Village Club. This research is an experimental research type with a sample of 12 people and analyzed using the t test. The results showed that the average pre-test score was 49 and the post-test average was 59, so it increased by 10 or equal to 20%. based on data analysis, the tcount value obtained is 24.00 then the results of the calculation are consulted on ttable with degrees of freedom 11, then ttable at a significant level of 5% is obtained 1.796 meaning tcount is greater than ttable. The conclusion of this study is that there is an effect on plyometric exercise on leg muscle power in volleyball athletes at the Kota Raya Village Club
