THE RELATIONSHIP BETWEEN LEG LENGTH AND LEG MUSCLE STRENGTH ON 100 M RUNNING SPEED IN STUDENTS OF SMAN 11 BULUKUMBA

Abstract

This study aims to determine; (1) Is there a relationship between leg length and 100 meter running speed in students of SMAN 11 Bulukumba; (2) Is there a relationship between leg muscle strength and 100 meter running speed in students of SMAN 11 Bulukumba; (3) Is there a relationship simultaneously between leg length and leg muscle strength and 100 meter running speed in students of SMAN 11 Bulukumba. The population in this study were all students of SMAN 11 Bulukumba. The sample used was 30 male students. In this study, the sampling method was by using a simple random sampling technique where samples were taken randomly. The data analysis techniques used in this study were descriptive analysis, correlation analysis, and regression analysis at a significance level of ? = 0.05 using the SPSS version 21 program. The results of the study showed that; (1) There is a significant relationship between leg length and 100 meter running speed in students of SMAN 11 Bulukumba, with a value of r = 0.590 (? < ? = 0.05); (2) There is a significant relationship between leg muscle strength and 100 meter running speed in students of SMAN 11 Bulukumba, with a value of r = 0.629 (? < ? = 0.05); (3) There is a significant relationship simultaneously between leg length and leg muscle strength and 100 meter running speed in students of SMAN 11 Bulukumba, with a value of the coefficient of determination (R2) = 0.624 or 62.4%.
