緒論：自運動浪潮開始後運動鞋的輕量化和減震能力一直都是評量運動鞋跑步經濟性（Running Economy）的重要指標（跑步經濟性詳見名詞操作型定義），各家運動鞋廠商相繼祭出新的材料以及結構追求輕量化和減震能力。TPMS結構是在19世紀就發現的幾何多孔結構，因平均曲率為零具備相較目前較常見的蜂巢和體心結構（BCC）具備更高的結構強度和能量分散的能力且同時具備多孔結構的特性，可能可以同時達成輕量化以及提升減震能力。
方法：本研究擬以光固化3D列印製作5種TPMS-Sheet結構，分別為Diamond、Gyroid、IWP、Neovius、Primitive，在三種相對密度分別為20%、30%、40%下進行撞擊測試。撞擊條件為高度30mm、重量8.2kg模擬人體慢跑的足跟撞擊。最後使用加速規紀錄時間和加速度的變化，先以butterworth 4th 低通道濾波器以288Hz進行資料處理，通過黎曼積分計算其壓縮量、平均加速度和吸收能量等數據用以評估各結構的減震能力，並比較單以加速度峰值作為減震評估依據的差異。
結果：在相對密度20%、30%、40%三種狀況下減震能力最佳的結構皆為Primitive，吸收能量的百分比在相對密度20%時是84.36%、在相對密度30%時是49.82%、在相對密度40%時是45.57%，且發現機械式的撞擊頭在撞擊過程中會出現4.2-7.7%的撞擊速度損失，其撞擊速度損失的因素可能來源於滑軌以及人為釋放撞擊頭。在所有的撞擊測試中撞擊頭壓縮後的反彈高度皆沒有超過對中底產生的壓縮量，表示其反彈時撞擊頭並沒有和中底分離；無法以反彈後的高度有效換算反彈位能。其反彈後的高度換算的反彈位能亦沒有明顯的趨勢。
討論：無論以加速度峰值大小抑或是能量吸收百分比皆表示Primitive是最佳的減震結構，單以加速度峰值測量無法考量到機械式撞擊測試器以及人為釋放撞擊頭產生的撞擊速度誤差，使用吸收能量百分比可能為更佳的減震能力評估方式。但Primitive在相對密度20%達最大壓縮量的時間為99.69ms大於以3.6m/s速度慢跑時產生的足跟撞擊時長40-50ms，表示其減震壓縮的時間和實際跑步的時間不相符，其結果可能也與材料特性相關，未來的研究亦可以朝這個方向發展。本研究僅提供撞擊測試的相關數據以及評估作為設計運動鞋中底的參考。

The present study evaluates the shock-absorbing capabilities of Triply Periodic Minimal Surface (TPMS) structures in athletic shoes. Using LCD 3D printing, five TPMS-Sheet structures are involved in the study: Diamond, Gyroid, IWP, Neovius, and Primitive. The relative densities (relative to resin) of the abovementioned structures are 20%, 30%, and 40%. Impact tests simulated jogging using 8.2kg impact head dropped from 30mm high. Results showed the Primitive structure had the best shock absorption, with energy absorption percentages of 84.36% at 20%, 49.82% at 30%, and 45.57% at 40% relative density. Despite the Primitive structure's effectiveness, its time to maximum compression (99.69ms) exceeds typical jogging heel strike duration (40-50ms), indicating a need for further research into material properties. The study provides essential data for designing athletic shoes midsole.
