The Correlation Between Leg Muscle Explosive Power and Long Jump Performance Using the Hang Style in Fifth-Grade Male Students at Dendeng Public Elementary School, Kupang Regency

Abstract

This study aims to determine the correlation between leg muscle explosive power and long jump performance using the hang style among fifth grade students of SDN Dendeng. The research employed a correlational method with a quantitative approach. The sample consisted of fifth grade students selected through purposive sampling. The instrument used to measure leg muscle explosive power was the vertical jump test, while long jump performance was measured by the students’ best jump results. Data were analyzed using the Product Moment correlation test. The results of the study indicate that there is a significant relationship between leg muscle explosive power and long jump performance in the hang style. The correlation coefficient obtained falls into the strong category, meaning that the better the students’ leg muscle explosive power, the higher their long jump performance. Thus, it can be concluded that leg muscle explosive power plays an important role in supporting students’ achievement in long jump using the hang style.
