Abstract :
Based on the results of observations of students in grade VIII SMP Negeri 25 Pekanbaru, researchers get problems include: the speed of running less fast prefix, doubt hesitate when will jump on the board repulsion, foot repulsion on the board less powerful, long jump technique sometimes not true. The purpose of this study is to determine the contribution of leg muscle power to the long jump results in students of class VIII SMP Negeri 25 Pekanbaru. This research type is correlation research. The population in this study are students of class VIII SMP Negeri 25 Pekanbaru which amounted to 18 people. The sample technique used is total sampling. The sample size is 18 male students. Instruments used in this study were a long jump test with no prefix and a long jump test. The conclusion of the result of this research is the contribution of leg muscle power to the long jump result of VIII students of SMP Negeri 25 Pekanbaru at 44,5%. R value count of 0.667. The r value of the table at n = 19 or df = 17 (5%) is 0.456. (attached). The comparison result is obtained under r arithmetic> r table or 0.667> 0.456.
