後蹬腳角度對擊劍長刺影響之研究

本研究目的旨在探討擊劍長刺動作不同後蹬腳角度（75°、90°、105°）之刺擊準確度、運動學與動力學的特徵及差異分析，以國家代表隊及全國運動會前三名之男子鈍劍及銳劍共8名選手為研究對象，各受試者須連結電審器並以三種不同後蹬腳角度站在KISTLER測力板完成長刺動作，使用VICON MX-F40動作分析系統同步擷取與收集各項力學參數，所得資料以描述性統計與單因子變異數分析檢定處理。經由分析研究結果後，獲得以下結論：一、在刺擊準確度方面達到顯著差異(p<.05)，以75°之準確度顯著高於90°與105°，受到心理狀態的影響下，優秀擊劍選手認為在75°下做長刺動作較為舒適亦容易推蹬，進而造成準確度有所差異；二、在運動學方面，不同後蹬腳角度之動作時間、最大劍速度與主要關節最大速度出現時間皆未達顯著差異；三、在動力學方面，不同後蹬腳角度之最大地面反作用力與衝量均無顯著差異。就整體表現而言，本研究顯示90°後蹬腳角度之長刺動作為最佳，因此在日常的教學實務及訓練，須養成選手良好的習慣並建立正確的動作觀念。

The purpose of this study is to analyze the variation in accuracy, kinematics, and kinetics characteristics resulting from the combination of different rear foot angles (75°,90°,105°) in fencing. Eight foil and epee fencers from national team and top three players from the national games were observed. Fencers were connected with the fencing machine and, according to the three different rear foot angles, stand on the KISTLER force-plate to accomplish lunge motions. VICON MX-F40 motion synchronism analysis system was used to obtain and collect each mechanics parameter. Data Analysis method by descriptive statistics and one-way ANOVA were processed. Research results showed: first, accuracy technique was significantly different in the different angles (p<.05), with 75° having the best performance compare to the other angles. The variation in accuracy is probably because of psychological influence, where fencers consider comfortable and easy push tread on 75°. Second, in the kinematics, motion time, maximum sword velocity, and main joints maximum velocity appear time of different rear foot angles were not significantly different. Third, in the kinetics, maximum ground counterforce and impulse of different rear foot angles were not significantly different. Whole display on this study show that 90° lunge motion of rear foot angle is optimum. For this reason, in teaching or training task, fencers need to cultivate fine habit and establish correct motion concept.
