Correlation between Uni-standing Balance Ability, Jumping Ability, and Anaerobic Lower Extremity Muscle Power of High School Taekwondo Players

Abstract

Objective: This study analyzed the correlation between uni-standing balance ability, jumping ability, and anaerobic lower extremity power of high school Taekwondo players. Design: Cross-sectional study Methods: Two high schools recruited 36 taekwondo players, but 5 were dropped due to personal circumstances and preparations for the tournament, so the number was counted as 31. In order to test uni-standing balance ability, the Romberg test was performed using Biorescue to measure the sway area. In order to test jumping ability, standing long jump and standing highjump were measured. For anaerobic lower extremity muscle power test, the peak power and average power were measured through 30-second pedaling using a Wingate system bicycle. Results: Participants did not show any correlation with other measures in the uni-standing balance ability test (p＞0.05). Looking at the correlation in the standing long jump, standing high jump (r＝0.892, p<0.05), anaerobic peak power (r＝0.698, p＜0.05), anaerobic average leg power (r＝0.662, p＜0.05) showed a positive correlation. Looking at the correlations in the standing high jump, anaerobic peak power (r＝0.663, p＜0.05), anaerobic average power (r＝0.697, p＜0.05) showed a positive correlation. Looking at the correlation in the anaerobic peak power, average power (r＝0.785, p＜0.05) showed a positive correlation. Conclusions: This study shows that balance ability and anaerobic leg strength are independent of each other. The results of this study can be used as basic data for the training plan of high school taekwondo players in the future.
