為探討女子足球選手髖、膝、踝關節伸肌和屈肌肌力與足背踢球球速的關係,乃利 用Merac等速肌力測量儀、雷達測速槍(Prospeed II)等設備,對18位自願的大專女子足球選 手(其中9位為國家儲訓選手)進行研究(平均年齡19.2±1.3歲,身高160.4±3.5公分,體重 53.9±4.7公斤),受試者分別在10、30及50rpm轉速下,以慣用腳做髖、膝、踝關節等速肌力 測驗,以雷達測速槍記錄足背踢球球速。結果發現在30rpm與50rpm轉速下,膝伸肌和膝屈肌 肌力均與踢球球速有顯著的相關r=0.53-0.80(p<0.05),表示女子足球選手膝伸肌和膝屈肌 肌力在快速收縮及中等速度收縮時,明顯的有利於踢球球速的增加。利用複迴歸之逐步迴歸統 計方法,得到球速的最佳預測模式:膝屈肌在50rpm轉速下佔踢球球速64.0%,在投入兩個變數 →膝伸肌在50rpm轉速下及髖屈肌在30rpm轉速下,合力佔踢球球速的72.3-80.1%,顯示髖屈 肌在踢球初期動作中,引導者膝關節快速收縮,有重要的作用,髖膝協同訓練應有助於球速的 改善。踢球球速的決定係數中仍有19.9%的變因,是由下肢其他肌力和全身各部位的相互協調 而來,可作為評量足背踢球學習和協調性訓練的參考。結論:膝關節快速收縮可發展出最大的 足背踢球球速,髖屈肌在指揮膝關節的功能上,不可忽視,踢球時全身肌力配合的協調性是可 評量的。

　　　　　The purpose of this study was to evaluate the relationship of isokinetic strength and velocity of instep kicking ball of college female soccer players. Eighteen female soccer players (mean age 19.2±1.3 yrs., mean ht. 160.4±3.5cm, mean wt. 53.9±4.7kg) were evaluated low limb isokinetic strength with Merac Isokinetic Dynamometer at the speed of 60 deg/sec, 180 deg/sec and 300 deg/sec and the velocity of kicking ball with radar speed gun. The results indicate that the correlation coefficients of velocity of kicking ball for knee extensor and flexor isokineteic strength at the speed of 180 deg/sec and 300 deg/sec were=.53 to .80 (p<.05). The regression equation of prediction velocity of kicking ball from low limb isokinetic strength was that velocity=40.47535-0.14117 (hip flexor isokinetic strength at the speed of 180 deg/sec)+0.59980 (knee flexor isokinetic strength at the speed of 300 deg/sec)+0.42998 (knee extensor isokinetic strength at the speed of 300 deg/sec), (R□=.80). It is concluded that the present finding can be applied for exercise prescription in college female soccer players.
