DAMPAK LATIHAN SINGLE LEG SPEED HOP DAN DOUBLE LEG SPEED HOP TERHADAP POWER TUNGKAI PADA PEMAIN BOLA VOLI

Abstract

This study aims to determine the effect of single leg speed hop and double leg speed hop training on increasing leg power. The type of this research is quasi experimental research with the non-randomized pretest-posttest modified design. The sample of this research is 30 students with ordinal pairing technique. The explosive power of the leg muscles was measured using a vertical jump test. Data were analyzed by t test, one way anava test and continued with the least significant difference (LSD) test using SPSS 21.0. The t test results of the two exercises showed a significance of the pre test and post test of 0.000. Based on the one-way ANOVA test, a significance value of 0.19 was obtained and the least significant difference (LSD) test showed that there was a difference in effect between the two exercises. So it can be concluded that the single leg speed hop and double leg speed hop exercises have an effect between the two exercises on the explosive power of leg muscles in male volleyball player students at PGRI Adi Buana University Surabaya.
