Abstract

The purpose of this study was to determine the contribution of leg muscle power and leg length to the 50 meter sprint ability of class VII.1 students of SMP Negeri 3 Pekanbaru. The type in this research is correlational with measurement techniques using correlation or relationship analysis. The sample in this study were all male students in class VII.1 of SMP Negeri 3 Pekanbaru with a total population of 18 people. The data analysis technique used in this research is multiple correlation test (R_(yx_1 x_2 )). Based on the calculations that have been made, the value of R_count = 0.813 is obtained. The calculated R value is then compared with the R_table at n of 18, which is = 0.468. The values of R_hitung and R_table are obtained that R_hitung≥R_tabel or 0.813≥0.468. With R_hitung≥R_table, there is a statistical relationship between leg muscle power and leg length on 50-meter sprints for class VII.1 students at SMP Negeri 3 Pekanbaru. Meanwhile, the coefficient of determination is 53.74%.
