摘要

Purpose: The purpose of this study was to compare the performance efficiency between the grab start and track start. Method: Twelve competitive swimmers participated in this study. Two digital video cameras (JVC, 60Hz) and the force plate (KISTLER, 1200Hz) were used to collect images of starts and kinetics parameters simultaneously. Kwon3D 3.1 Motion System and Bioware 3.0 software were used to analyze data. The SPSS software was adopted to calculate the values of the parameters and repeated measures t-test used to test the differences between these two starts. Results: The results of this study were shown significant differences between these two starts in glide time, takeoff velocity, flight distance, impulse, impulse efficiency (p＜.05). And there were no significant differences in block time, flight time, 7m velocity and Fmax. For the performance efficiency, the track start was significantly higher than grab start in performance efficiency. Conclusion: This study concluded that the track start with higher performance efficiency compared to the grab start was due to the less effort with the same level of performance.
