不同層級羽球選手殺球球速與關節角速度之分析
A study of smash ball velocity and joint angular velocity between elite and sub-elite badminton players
摘要
研究目的：本研究目的為探討大專不同層級羽球選手，在殺球時之球速與關節角速度差異。方法：本研究以大專甲、乙組各九名選手為研究對象，以動作捕捉系統與測速槍量測其殺球瞬間最高球速與上肢關節角速度。再以Matlab 2008a電腦語言自行編寫程式計算其腕關節角速度、肘關節角速度與肩關節角速度。統計方法以獨立樣本t檢定，考驗甲、乙組選手之差異。並以多元迴歸分析，找出對球速的預測力。本研究水準設為α=.05。結果：甲組選手在球速、腕關節角速度與肘關節角速度上，皆顯著的大於乙組選手。在甲組選手中，腕關節角速度與肩關節角速度皆為影響球速之因子；而乙組選手僅受腕關節角速度影響。結論：羽球選手殺球時上肢各關節的角速度需符合動力鏈順序性，依肩關節、肘關節及腕關節的順序依次加速，以利將動量傳遞至拍頭形成鞭打效應。

Purpose: The purpose of this study was to compare and analyze the differences of ball velocity and the joint angular velocity of the upper extremities between elite and sub-elite collegiate badminton players. Methods: Eighteen elite and sub-elite badminton players were recruited in this research. The motion analysis system and radar gun were used to measure the ball velocity and joint angular velocity of the upper extremities during smash. The Matlab 2008a computer language was used to compute the wrist, elbow, and shoulder joint angular velocity. The independent samples t-test was applied to test the differences between groups. In addition, the linear regression was applied to explore the main factors of ball velocity. The significant level was set at α= .05. Results: The results indicated that the ball velocity, wrist and elbow joint angular velocity were significant superior in elite players and the wrist and shoulder joint angular velocity were the main factors of ball velocity. However, the wrist joint angular velocity was the only factor which dominate the ball velocity in sub-elite players. Conclusions: During smash, the players need to follow the role of kinetic chain to improve the joint angular velocity form proximal to distal to reach the higher ball velocity.
