高爾夫揮桿應該是偏向使用慣用手或是非慣用手的運用為主，才是對桿頭速度具有較大貢獻的問題，目前尚未有明確的答案。因此本研究目的為探討國內6名優秀大專女子高爾夫選手(平均年齡21.8歲)其慣用手和非慣用手之腕關節在60°/s、120°/s和180°/s三個不同角速度下和肘關節、肩關節在60°/s、180°/s和300°/s三個不同角速度下所分別產生的峰值轉矩值(peak torque)，且以SPSS 10.0軟體，進行成對樣本t考驗(α=.05)檢驗優秀大專女子高爾夫選手慣用手(後繼手)及非慣用手(前導手)之等速肌力差異，藉此來了解兩者角色的重要性。其結果顯現出非慣用手手腕在等角速度120%往尺側偏移(ulner deviation)動作方向所產生的等速肌力大於慣用手，而手肘在等角速度180°/s下的伸展(extension)動作方向和肩膀在等角速度60°/s下的前伸(toward)動作方向的等速肌力均為慣用手大於非慣用手。從本研究的結果，期望能夠給予教練了解對於腕關節、肘關節和肩關節在不同速度上的差異，以應用於肌力訓練上，且提供教學參考的依據和選手們訓練的方向，以求在桿頭速度上能夠更快，球飛行的更遠，並期望能在國際上有傑出的表現，締造更好的佳績。

The answer to the dominated or undominated hand contributing the clubhead speed is still not clear. Thus, the purpose of this study explored the peak torque of six elite college female golf players (average ages = 21.8) of the wrist joint of the dominated and undominated in 60°/s,120°/s and 180°/s three different angular velocities and shoulder and elbow joints in 60°/s,180°/s and 300°/s three different angular velocities. SPSS 10.0 for Windows, Paired­Samples t test analysis of the isokinetic strength of college golf players' dominated or undominated hand. The result indicated that the torque of the undominated hand in wrist ulnar deviation direction was more active than the dominated hand in 120°/s velocity, extension of elbow in 180°/s and the toward of shoulder in 60°/s during forward swing reveal that the dominated hand was more active than the undominated hand. The results of this study, we hope, can provide three different joints in three velocities, from low to high, for coaches to train golf players to make a faster clubhead speed and a farer ball distance to gain the best performance in the international competition.
