Abstract

The purpose of this study was to determine the contribution of leg muscle power to the triple jump ability of class XI students of Bangkinang City 2 High School. This type of research is correlational research. The population in this study were all male students of class XI of Bangkinang State High School 2, Kampar Regency, amounting to 109 people. The sampling technique used purposive sampling, so the researchers made the sample in this study was 15%, namely as many as 16 male students taken from each class. The instrument of this study used a standing broad jump test and an triple jump test. In the implementation, 1 student suffered injuries so that the data collected was only 16 people. The results of calculations performed obtained a correlation index of 0.545. This value is then compared with the r table value at n = 16 or df = 14 with a 5% error rate of 0.497. the calculation results obtained by the value of t arithmetic = 2.43. The value of t table at df = 14 is 2.14. The comparison results obtained by the value of t arithmetic (2.43)> t table (2.14), therefore the contribution of variable X to variable Y is significant. The coefficient of determination is 29.7%. The conclusion of this study is that there is a contribution of explosive limb muscle power to the results of triple jump of Class XI students of Bangkinang State Senior High School 2 in Kampar Regency in the amount of 29.7%.
