Abstract

Abstract : This study aims to determine whether there is a correlation between leg muscle power and short-distance running speed of 100 meters of grade VIII^a male students of Junior High School 9 Tapung.  This research is correlation research, the population in this study is grade VIII^a male students of Junior High School 9 tapung, the sample in this study amounted to 15 people.  The sample technique used is total sampling, where all populations are sampled. Thus the sample in this study amounted to a sample of 15 class VIII^a male students of Junior High School 9 Tapung. After that, the data is processed statistically, to test normality with the lilifors test and correlation at a significant level  (0.05). The first analysis between leg muscle power (X1) with the running speed of 100 meters of class VIII^a male students of 9 Junior High School Tapung (Y)  , where rtab at a significant level  (0.05) = 0.532 which rcount (0.161)> rtab (0.532), it means that the hypothesis is accepted and there is no strong relationship between leg muscle power and short-distance running speed of 100 meters, the second analysis is the relationship between leg muscle power (X1) and short-distance running speed of 100 meters (Y) was obtained, where rtab at a significant level  (0.05) = 0.532, which rcount (0.161)> rtab (0.532).  It can be concluded that the relationship between (X1) and (Y) or the relationship between leg muscle power and the running speed of 100 meters of grade VIII^a male students of  Junior High School 9 Tapung is significant.
