CORRELATION ANALYSIS OF PHYSICAL FITNESS ON THE OPTIMIZATION OF MOTOR ABILITIES IN JUNIOR HIGH SCHOOL STUDENTS

Abstract

This study aimed to analyze the correlation between physical fitness and the optimization of motor abilities among junior high school students. This research employed a quantitative method with a correlational design. The research sample consisted of 120 junior high school students selected using purposive sampling technique. Data collection instruments included the Indonesian Physical Fitness Test (TKJI) to measure physical fitness components and the Test of Gross Motor Development-3 (TGMD-3) to measure motor abilities. The results showed a positive and significant correlation between physical fitness and students’ motor abilities (r = 0.78; p < 0.01). The physical fitness components that most contributed to motor abilities were muscular strength (r = 0.72), followed by cardiovascular endurance (r = 0.68), agility (r = 0.65), and flexibility (r = 0.58). These findings indicate that improving physical fitness plays an important role in optimizing students’ motor abilities
