The relationship between limb length and lower-limb explosive power on squat-style long jump performance in junior secondary students / Karina Octaviani

Abstrak
Background To determine the relationship between leg length and leg muscle explosive power with squatting style long jump performance applied to junior high school students. Objectives This study aims to examine the relationship between leg length and leg muscle explosive power together with the ability to long jump squatting style. Methods The method used is quantitative descriptive design with an correlational study. The study population amounted to 60 male students in class VIII. Sampling using Purposive Proportional Systematic Random Sampling technique amounted to 45 students. The collected data were analyzed using 3 prerequisite tests namely data normality test homogeneity test and linearity test. After fulfilling the prerequisite test requirements it can be continued with 4 hypothesis tests product moment test multiple correlation test regression equation line and effective contribution and relative contribution. Results The data obtained using inferential statistics in the form of multiple correlation analysis is complemented by multiple regression analysis. The results of the multiple correlation test obtained a coefficient 0.687 and Sig. P 0.001 lt a 0.05. Conclusion The conclusion of the study is that there is a positive and linear relationship between leg length and leg muscle explosive power with squatting long jump ability. Based on the results of this study it is recommended for further research to conduct further studies by considering the addition of variables such as speed flexibility and confidence levels that affect the performance of squatting long jump results.
