Abstract

M Hafiz, 2020. The Contribution of Leg Muscle Power to the Sprint Speed of 50 Meters of Class 2F Students in the Penjaskesrek Study Program at the Riau Islamic University. Leg muscle power is related to sprint speed. Because leg muscle power is the ability to release maximum strength in a short time. The purpose of this research is to determine the contribution of leg muscle power to the sprint speed of the 50 meter class 2F students of the Penjaskesrek Study Program at the Islamic University of Riau. This type of research uses a correlational research design. The population of this research is the 2F grade students of the Penjaskesrek Study Program, Riau Islamic University. The technique of determining the sample using cluster random sampling technique, namely students of class 2F, Penjaskesrek Study Program, Riau Islamic University, amounting to 32 people. The instrument used in this study was to do a leg muscle power test and a 50 meter sprint speed. Analysis of the data used is the product moment correlation test, and the coefficient of determination test. Based on the results of research and data processing obtained values with r arithmetic ≥ r table at a significance level of 5% and the coefficient of determination obtained is 25.4016. so it can be concluded that there is a significant contribution of leg muscle power to the sprint speed of the 50 meter class 2F students of the Penjaskesrek Study Program at the Riau Islamic University.
