Correlation Of Leg Length And Leg Muscle Power Towards Futsal Shooting In Extracurricular Students Of Smp Bina Satria Mulia Medan In 2025

Abstract

This study aims to determine the relationship between leg length and leg muscle power on futsal shooting ability among extracurricular students at SMP Bina Satria Mulia Medan in 2025. The research background is based on the low conversion rate of scoring opportunities among futsal extracurricular students, where only 40% of students achieve the minimum shooting success standard. The research method used was correlational research with a three-variable reciprocal relationship design. The research population consisted of all futsal extracurricular students at SMP Bina Satria Mulia Medan, totaling 32 students, using total sampling technique. Research instruments included leg length measurement using an anthropometer, leg muscle power test using Standing Broad Jump, and futsal shooting test with scoring targets. Data analysis employed Pearson correlation and multiple regression with a significance level of α = 0.05. The research results showed: (1) There was a significant positive relationship between leg length and futsal shooting ability (r = 0.356; p = 0.045 < 0.05); (2) There was a significant positive relationship between leg muscle power and futsal shooting ability (r = 0.378; p = 0.033 < 0.05); (3) There was no significant relationship between leg length and leg muscle power (r = 0.162; p = 0.379 > 0.05); (4) The multiple regression model showed that the combination of leg length and leg muscle power together contributed 23.2% to futsal shooting ability (R² = 0.232; F = 4.379; p = 0.022 < 0.05). The conclusion of this study is that there is a significant positive relationship between leg length and leg muscle power with futsal shooting ability, with leg muscle power having a more dominant contribution. This indicates that both anthropometric and physiological factors play important roles in determining futsal shooting ability, although there are still 76.8% of other factors affecting shooting ability beyond the variables studied.
