Abstract

The purpose of this study is to determine the contribution of leg muscle explosive power and leg length to the results of the high jump straddle force in SMA Negeri 6 Pekanbaru students. This type of research is correlation. Population and sample in this study were all students of class X IPS 2, 25 people and the sample of 15 students. The instruments of this study include the leg muscle explosive test that is vertical jump, leg length test using a meter and straddle style high jump test. The data analysis technique is the correlation value test. Based on the results of research that has been done, it can be concluded that there is a contribution of leg muscle explosive power (X1) and the high jumping results of straddle force in high school 6 Pekanbaru (Y) high school students, which is found to be calculated = 0.53 At a significant level of 5 % found rtable = 0.514, thus rcount> rtable or 0.53> 0.514, with a contribution of 28.09%. Contribution of limb length (X2) and straddle force high jump results in 6 Pekanbaru (Y) High School students, which was found to be r = 0.53 At a significant level of 5% was found rtable = 0.514, thus rcount> rtable or 0.53 > 0.514, with a contribution of 28.09%. Contribution of leg muscle explosive power (X1) and leg length (X2) with the high jumping result of straddle force on 6 Pekanbaru (Y) High School students, which was found to be r = 0.699 At a significant level of 5% found rtable = 0.514, thus rcount> rtable or 0.699> 0.514 in the strong category with a contribution of 48.86%.
