Abstract:	本研究主要目的為比較兩種不同拍型對近檯正手弧圈技術表現和生物力學之影響。方法:本研究招募新北市 10 位右手持拍之高中男子組選手為受試者，每位受試者分別各完成兩次六角形狀球拍和兩次一般形狀球拍執行近台正手弧圈，研究過程中以高速攝影機對擊球速度進行截取，運動學資料以 Kwon CC 進行比例尺設定在以 Kwon 3D 進行資料處理，統計方式採用無母數統計中魏克生符號等級檢定 (Wilcoxon signed-rank test) 分析比較上肢運動學參數在兩隻球拍間之差異，統計顯著水準為 α = .05 。結果:本研究結果發現在擊球初速度方面六角形狀球拍快於一般形狀球拍，其餘參數皆無達到顯著差異。結論: 本研究結論，習慣出球速度快的選手可以選擇使用六角形狀球拍，提升出球度，建議進一步討檯內技術與兩種不同形狀球拍的關係，以深入了解兩種不同球拍對運動表現的影響。 The main purpose of this study is to compare the performance and biomechanical effects of two different racket designs on the forehand topspin technique in table tennis. Methods: Ten male high school players from New Taipei City were recruited as subjects, all of whom were right-handed. Each participant completed two sessions of executing forehand topspin shots using a hexagonal-shaped racket and two sessions using a regular-shaped racket. High-speed cameras were used to capture the ball speed, and kinematic data were processed using Kwon CC for scaling and Kwon 3D for data analysis. Results: The Wilcoxon signed- rank test was employed for comparison of outcome variables of interest between the two rackets. Statistical significance was set to α = .05. Conclusion: The results of this study revealed that the hexagonal-shaped racket exhibited a higher initial ball velocity compared to the regular- shaped racket, while no significant differences were found in other parameters. The conclusion of this study suggests that players accustomed to faster ball velocity may consider using a hexagonal-shaped racket to improve shot velocity. Further research is recommended to investigate the relationship between in-game techniques and the two different racket designs, in order to gain a futher understanding of the impact of these rackets on athletic performance.
