本研究目的在評估不同慢跑鞋與運動表面組合在不同撞擊能量下之避震特性。兩雙市售慢跑鞋及兩種運動表面（PU 及柏油）之不同組合接受撞擊測試，撞擊能量介於3.19-6.67 joule 。測試結果發現，撞擊能量愈大所測得慣性力峰值（撞擊器質量×負加速度峰值）愈大。在五種組合情況中，僅撞擊PU 表面時，測得慣性力峰值最大。比較其他四種鞋與表面的組合，鞋2 與柏油路面的組合在所有撞擊能量下所測得力量峰值皆較高；在低撞擊能量下（3.19 joule），鞋l 與PU 、鞋2 與PU 、鞋1 與柏油之組合，所測得力量峰值差異不大；然而，在高撞擊能量下（6. 67 joule），鞋2 與PU 、鞋l 與柏油之組合所測得力量峰值則高於鞋l 與PU之組合。由本研究結果發現，鞋底與運動表面在整體組合之避震效應上，扮演同樣重要的角色；而且，在較低撞擊能量下，鞋底或運動表面其中之一具有較佳的避震能力，便能保有整體較佳的避震效果；在較高撞擊能量下，則必須鞋底與運動表面都具有較佳的避震能力，才能呈現出較好的避震效果。因此，建議在進行低撞擊能量的運動時（如步行），鞋底與運動表面之間至少須一個具有避震的效果；而在進行高撞擊能量的運動時（如慢跑）或是體重較重的人，應穿著避震效果好的鞋子，並且在PU 等具有較佳避震效果的表面進行活動。

　　The purpose of this study was to evaluate the cushioning properties of different shoe-surface combinations in different impact energies. Five shoe-surface conditions were tested in twelve different impact energies (3.19-6.67 joule). The results showed that higher impact energy increased the peak inertial force (mass of striker×peak deceleration) in each condition. Larger peak inertial forces were found in Cl (polyurethane only) and C5 (shoe2+ asphalt) conditions. In low impact energy, the peak inertial forces were similar in C2 (shoe 1 + polyurethane), C3 (shoe2+ polyurethane) and C4 (shoe 1 + Asphalt) conditions. However, the peak forces in C3 or C4 were larger than C2 in high impact energy. It was concluded that people ought to choose at least a well-cushioned shoe or surface when doing low impact energy activities, such as walking or jogging, and must choose both well-cushioned shoe and surface when doing high impact energy activities.
