Abstract

INTRODUCTION
The purpose of this study was to investigate the correlation between Wingate test and isokinetic test for anaerobic power and to identify which isokinetic test variable can best predict anaerobic power.
METHOD
The subjects were 14 college male golfers. Anaerobic power was assessed by 30-second Wingate test and isokinetic test at 60, 180, 240°/s. In order to analyze collected data, pearson product moment and multiple regression analysis were utilized. The statistical significance was accepted at .05 levels.
RESULT
There was significant correlation between mean power in isokinetic knees extension at 60°/s and mean power of wingate test(r=.862, p<.01; R 2 =.743, p<.001). There was significant correlation between peak torque % body weight in isokinetic knees extension at 60°/s and mean power of Wingate test(r=.785, p<.05; R 2 =.775, p<.001). There was significant correlation between total work in isokinetic knees flexion at 60°/s and mean power per body mass of Wingate test(r=.762, p<.01; R 2 =.581, p<.01). And there was significant correlation between mean power in isokinetic knees extension at 60°/s and total work of Wingate test(r=.862, p<.01; R 2 =.743, p<.001). Although there was significant correlation between time to peak torque in isokinetic knees flexion at 60°/s and time to peak power of Wingate test(r=.-533, p<.01), time to peak torque could not precisely predict time to peak power. There was significant correlation between total work in isokinetic knees extension at 240°/s and peak power of Wingate test(r=.880, p<.01; R 2 =.775, p<.001), There was significant correlation between total work in isokinetic knees extension at 240°/s and fatigue index of Wingate test(r=.853, p<.01; R 2 =.728, p<.001).
CONCLUSION
Knee extension peak torque % body weight, average power at 60°/s, and total work at 240°/s were best important variables that can predicts anaerobic power when evaluated by using isokinetic test. Also total work at 60, 240°/s should be considered as anaerobic power variable. Time to peak torque of Wingate test was not proper variable to predict anaerobic power.
