    摘要: 目的：本研究目的為了解網球選手跑 / 跨步動作介入足弓墊與一般足墊，比較兩者在靜態平衡晃動面積、網球截擊與底線擊球深度、生物力學下肢關節剪力、地面反作用力及踝關節內翻與蹠屈角度的差異。方法：招募20名文化大學男性網球選手 (178 ± 4公分；70 ± 5公斤)，依據受試者足型及腿型選擇相對應的足弓墊，並適應足弓墊2週後，再與一般足墊進行比較。檢測方法分成三類：1.靜態平衡表現：採取開眼與閉眼雙腳站姿並維持身體平衡10秒鐘，比較赤足與足弓墊之間晃動面積的差異。2.網球運動表現：足弓墊與一般足墊的介入比較對截擊與底線擊球深度的差異。3.生物力學測量：分為單腳跨步切入、側向急煞、分腿墊步等三項動作，透過光柵系統閃光模擬來球方向，每項動作執行6次。以成對樣本t檢定分析赤足與足弓墊靜態平衡的差異、足弓墊和一般足墊與網球運動表現、生物力學檢測之間的差異。結果：靜態平衡達顯著差異，但足弓墊晃動面積大於赤足；網球運動表現截擊及底線擊球均達到顯著差異；單腳跨步切入地面反作用力峰值達顯著差異，足弓墊小於一般足墊，右踝、右膝關節剪力達顯著差異，足弓墊大於一般足墊；側向急煞肢段地面反作用力峰值均達顯著差異，足弓墊小於一般足墊，右踝關節蹠屈角度、右踝內翻角度及左踝蹠屈有顯著差異，足弓墊小於一般足墊，而左足內翻角度未達顯著差異；分腿墊步地面反作用力峰值與踝、膝關節剪力，主要在著地後往右方向推蹬有明顯的顯著差異，足弓墊小於一般足墊，而往左方向並未發現顯著差異。結論：足弓墊的介入對網球下肢動作對地面的撞擊力有顯著的減少，而且能減少在側向急煞時踝關節的蹠屈及內翻，增進踝關節穩定性。
    Purpose: The aim of the study was to investigate differences between arch-support insole and normal insole in static balance wavered area, volley depth and ground stroke depth of tennis performance, knee and ankle joint shear force, ground reaction force, ankle inversion and ankle flexion during tennis movement. Method: Subjects were 20 male tennis players from Chinese Culture University (178 ± 4 cm；70 ± 5 kg). The arch-support insoles were chosen according to subjects’ foot and leg type and subjects wore the insoles for at least 2 weeks for accommodation. There were three parts of measurement: 1. Static balance: standing with eyes closed and open for 10 seconds in barefoot and arch-support insole was measured. 2. Tennis performance: volley depth and groundstroke depth were measured in insoles with and without arch-support. 3. Biomechanics: step-cutting, side braking and split step were measured with smart speed which simulated the ball direction in insoles with and without arch-support. Paired-samples T-test was used for analysis. Results: Static balance: significant difference was found between arch-support and barefoot. But the wavered area of arch-support insole was greater than that of barefoot. Tennis performance: significant differences of volley depth and ground stroke depth of tennis performance were found between arch-support and normal insole. Biomechanics: significant difference peak ground reaction force of step-cutting, side braking and split step were found between arch-support and normal insole. The peak ground reaction force of arch-support insole was smaller than the normal insole. Right ankle flexion, inversion and left ankle flexion showed significant differences in side braking between arch-support and normal insole. Ankle and knee joint shear force showed main effect significant differences in split step between arch-support and normal insole. Conclusion: The arch-support insole can reduce the ground impact force and increase the ankle stability during tennis movement.
