Abstract

The purpose of this study is to determine the contribution of leg muscle explosive power and leg length to the results of straddle-style high jumping at 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 the research that has been done, it can be concluded that there is a contribution of leg muscle explosive power (X1) and high jumping straddle force results in 6 Pekanbaru (Y) High School (Y) students, where rcount = 0.53 At significant level 5% is found rtable = 0.514, thus rcount> rtable or 0.53> 0.514. There is a contribution of leg length (X2) and straddle force high jump results in 6 Pekanbaru (Y) High School students, which is found to be r = 0.53 At a significant level of 5% found rtable = 0.514, thus rcount> rtable or 0, 53>0.514. There is a contribution of leg muscle explosive power (X1) and leg length (X2) with the high jumping result of straddle force in high school 6 Pekanbaru (Y) high school students, which is found to be counted = 0.699 At a significant level of 5% found rtable = 0.514, thus rcount > r table or 0.699> 0.514 in the strong category.
