目的:在比較五人制足球十公尺定點腳背射門動作中，優秀與次優秀選手間的差異性，探討的有球速、足加速度、人體下肢段加速度運動學參數關係。方法:受試對象以國中優秀與次優秀選手各一名，慣用腳皆為右腳。利用無線微機電感測器，內含三軸加速規。實驗時在受試者的右踝、右膝、左踝、左膝、右腰各配戴1個感測器，擷取優秀選手與次優秀選手在定點腳背射門時相關之運動參數。結果：1.優秀和次優秀選手在個人球速上配戴和未配戴感測器無顯著差異(顯定水準為0.05)；2.優秀與次優秀選手之間在球速上無論是否配帶感測器皆達顯著差異；3.優秀與次優秀選手在踢球時間上有顯著差異；4.優秀與次優秀選手在身體下肢段三軸加速度上，經檢定後右踝、右膝、左踝和左膝的合力均達顯著差異。結論：1.配戴感測器不會影響選手的射門球速表現；2.踢球的時間優秀選手大於次優秀選手；3.選手配戴感測器踢球時間之差異比較，達顯著差異，在優秀選手的最小值中，代表前後擺腿方向移動的X和Z軸，位移比次優秀手較大，使得踢球時間較長。4.下肢段三軸加速度的比較，五個肢段點的二十個比較值當中，十四個有明顯差異，顯示優秀選手與次優秀選手在十公尺射門時，動作是有明顯的不同。
