本研究主要在探討跑鞋鞋底磨損程度與跑步速度對著地
期踝關節外翻角度的影響，並在三者之間建立一迴歸公式，
以跑鞋鞋底磨損程度與跑步速度預測踝關節最大外翻角度變
化情形。本研究以鞋底內側有嚴重磨損之受試者二十名為研
究對象，採用Benno.Nigg 之實驗方法，以 Peak動作分析系
統及每秒 120張之攝影機，攝影機架設於受試者之正後方以
拍攝每位受試者分別著四種實驗鞋在跑步機上跑三種速度之
跑步動作，影片資料係利用Peak動作分析系統影片數位化過
程處理，並採用線性迴歸統計方法探討踝關節外翻角度、跑
步速度、底磨損程度三者間之關係。
其結果加以討論後得到以下結論；
一、 就跑步機速度與踝關節外翻角度之關係而言；踝關節外翻角
度隨速度之增加而增加。
二、 就跑鞋鞋底磨損與踝關節外翻角度之關係而言；在跑鞋鞋底
磨損越多踝關節外翻角度越大。
三、 就跑步跑步速度與跑鞋鞋底磨損對踝關節外翻角度而言，在
跑步機速度越快與跑鞋鞋底磨損越多時，踝關節外翻角度越
大。
四、 本研究得知踝關節外翻角度、跑步速度、鞋底磨損等三者之
間關連密切，因此本研究以跑步速度與鞋底磨損兩個自變項
頇測一個依變項外翻角度所建立之迴歸方程式為：
最大外翻角度變化量=6.13+1.028×跑步速度(英哩/小時)
+0.428×鞋底磨損程度(公釐)

The purpose of the study was mainly toexplore the influence
caused by the worn-down condition of medical sole of shoes
and running speed on the ankle pronation degree，
In th stuy ,each subject was assigned to wear four diffe
-rent pairs of shoes in order which were made up of four dif
-ferent midsole height ( 19mm. 15mm. 11mm. 7mm) running on a
treadmill at a speed of 5.2 , 6.9 , and 8.9 m/h .High -speed
camera was used to record twenty subjects from the rear of
treadmill running on a treadmill.The video tape was digitized
by operating a set of PEAK PERFORMANCE ANALIZING SYSTEM，and
regression analysis was utilized to explore the relationship
of the three variables。After data treatment，the results
were listed as followed:
一、As far as the relationship between running speed and the ankle
pronation degree were concerned ,pronation degree increased
with the increase of running speed .
二、As far as the relationship between LB.shoes and the ankle
pronation degree were concerned ,pronation degree increased
with the increase of the worn-down condition of medical sole
of shoes.
三、As far as the influence caused by running speed and LB.shoes
insimultaneously was concerned ,pronation degree incresed
with the increase of the running speed and the worn-down con
-dition of medical sole of shoes.
四、The regression formula ,Y = 6.13+1.028×X1+0.428×X2, was
established to represent the relationship among the maximun
pronation degree of the ankle , running speed and worn-down
The purpose of the study was mainly toexplore the influence
