Abstract:	臺灣從事棒球運動的人口、各級學校棒球校隊或社團的數目逐年增加，對於能增進棒球運動表現與預防運動傷害的相關產品，棒球選手們都是趨之若騖。本研究主要目的為分析棒球投手穿著運動功能性足弓墊投球時，對直球球速、控球準確度、膝關節穩定度，以及踝關節穩定度之影響。本研究採用重複量數相依樣本之實驗設計，受試者隨機穿著兩種足墊於室內牛棚之人工投手丘上進行投球實驗。兩種不同足墊中，一為歐立達公司所研發之運動功能性足弓墊，另一為美津濃（Mizuno）棒球釘鞋所附之足墊。進行測驗時，每位受試者共投30球快速直球，前一球投出後，受試者必須在接到捕手回傳球後的20秒內投出下一球。資料蒐集後，以相依樣本t檢定比較受試者穿著不同足墊投球時，在各項實驗變項的數值上是否有顯著差異。研究結果顯示，穿著運動功能性足弓墊投球時，快速直球的球速提高0.2%、控球準備度提高5%、好球率提高2%、跨步腳之踝關節穩定度提高 9%，以及跨步腳著地衝擊力降低1%，但上述分析在統計上未達顯著差異。此外，研究結果也顯示，跨步腳之膝關節穩定度提高10%，並達顯著差異水準。因此，本研發現穿著運動功能性足弓墊投球時，雖然無法大幅提升快速直球的球速，但有能效提升投手控球的準確度及跨步腳膝關節的穩定度。 Within these few years in Taiwan, the number of participants in baseball have been increasing . Sport injury prevention and performance enhancement products are popular among players. The purpose of this study is to analyze how pitching with functional arch support insoles can affect the stabilities of knee and ankle joints, accuracy of ball control, and velocity of fastball. This study was a repeated measures design. Subjects were asked to wear two different foot insoles and pitched fastball on an indoor pitching mount. Subjects were asked to pitch 15 fastballs and had to deliver the next pitch within 20 seconds after receiving the ball from the catcher. Pair sample t-test was used to analyze and compare the data collected from the experiment. The result shows that subjects wearing the functional arch support insole increased the velocity of their fastball by 0.2%, the accuracy of ball control by 5%, the percentage of strike by 2%, the stability of the leading foot ankle by 9%, and the impact of the leading foot decreased by 1%. All of the aforementioned parameters were not statistically significant except for the stability of the leading foot knee which increased by 10%. The study concluded that the effect of wearing functional arch support insole on the velocity of fastball was small but it showed a large improvement in the stability of the leading foot knee.
