摘要

目的：探討鞋底前後足高度差（後足加高、前足加高以及不加高）與速度
對於下肢動力學、運動學及肌肉活性之影響。方法：本研究招募年齡介於 18 至 24 歲的 11 名大專院校生（身高 170.18±2.15 公分、體重 65.73±8.09 公斤、年齡 21.27±2.15 歲）為研究對象，使用高速攝影機 (200 Hz)、測 力板 (1000 Hz) 以及表面肌電儀 (2000 Hz) 來觀察鞋底前後足高度差與
速度對於下肢動力學、運動學及肌肉活性之影響。統計方法以重複量數二 因子變異數分析進行統計，顯著水準設為 α=.05。結果：在前足鞋底加高 下髖關節內收 (P=.028<.05) 及外轉 (P=.018<.05) 受力會較大而踝關節 內翻受力 (P=.007<.05) 較小，且減少髖關節屈曲力矩 (P=.017<.05)，當
速度增加時，下肢動力學及運動學參數都隨之改變。結論：前足鞋底高度
增加能減少髖關節屈曲力矩的產生，並且同時減少了踝關節的內翻受力，
而這樣的改變可能可以降低在跑步時的髖關節及踝關節傷害。建議：軀幹
傾斜角度也可能影響下肢動力學、運動學及肌肉活性，因此建議未來可以 探討不同鞋底高度對於軀幹傾斜角度的影響。

Purpose: The aim of this study was to investigate the effect of different heelto-toe drops to lower limb kinetics, kinematics and muscle activation. Methods: Eleven college students were recruited in this study (height:170.18±2.15cm； weight:65.73±8.09kg；age:21.27±2.15 years old). Experimental apparatus including high speed cameras (200Hz), force plate (1000Hz), and surface electromyography (2000Hz). The lower limb kinetics, kinematics and muscle activations resulted by different heel-to-toe drops and speeds were investigated in this study. Repeated measures two-way ANOVA were used in statistical trail and the significance level was α=.05. Results: The results indicated that when wearing the thickened-forefoot outsole the hip adduction and external rotation force were higher while a lower ankle inversion force and hip flexion torque was observed. When running speed increased, kinetic, kinematic parameters changed along with different speeds. Conclusions: In conclusion, elevate outsole in forefoot can reduce torques caused by hip flexion, and ankle inversion force at the same time, which is able to attenuate injuries in hip and ankle during running. Suggestion: The angle between trunk and the ground might also affect lower limb kinetics, kinematics, and muscle activation. Thus, it is recommended that studies investigated different heel-to-toe drops to trunk angle could be commenced in the future.
