The Relationship Between Leg Explosive Power and Flexibility and Long Jump Ability in Squat Style

Abstract

This research aims to determine the relationship between leg explosive power and flexibility and long jump ability in squatting style at UPT-SPF students at SD Inpres Panaikang II/1. This research is a descriptive study with one dependent variable, namely squatting long jump ability. The sample in this study consisted of 50 students. The instruments in this study used a long jump test without a start for leg explosive power, a forward bending flexibility test for flexibility data, and a squatting long jump ability test for squatting long jump ability data. Data analysis obtained the following results: (1) There is a relationship between leg explosive power and squatting long jump ability with correction results (r) = -0.451 (P < 0.05). (2) There is a relationship between flexibility and squatting long jump ability with a corrected value (r) = -0.425 (P < 0.05). (3) There is a joint relationship between leg explosive power and flexibility and squatting long jump ability with a corrected value of (R) = 0.496 (P < 0.05) and F value = 7.652 (P value = 0.000 < 0.05).
