鈍劍握把角度最佳化之實驗研究

An Experimental Study of Optimal Handle Angles of the Foil Blade

本研究以Emanuel等人之手工具與運動器材最佳化人機介面的理念，進行最佳化角度擊劍握把設計實驗，受試者來自大專院校男子鈍劍選手共8名，其中四名選手曾獲得大專院校錦標賽前3名成績，四名選手為全國運動會縣市代表隊選手。本實驗設計延用Lin和Chang研究之3°到15°劍身下壓角度的研究結果，保留9°和15°兩個角度，再結合Emanuel等人研究之19°±5°最佳化角度，設計實驗角度為9°、15°、18°、21°、24°。實驗以鈍劍不同握把角度應用在甩劍刺擊的有效性、刺擊的準確性的綜合研究，研究發現，19.5°±3°為鈍劍最佳握把角度的範圍，此範圍符合手工具握把最佳角度19°±5°之原則。This study adopted the optimization concept of the human machine interface of tools and sport instruments developed by Emanuel et al. to design an experiment on large angle fencing handles. Participants were eight male university students who are fencers. Four of the fencers had won the top three places in the college champion ship competition, and four fencers were representatives from their respective counties/cities in national competitions. This experiment adopted the study results of downward angles of 3° ~ 15°of Lin & Chang . This experiment reserved angles of 9° and 15°, and added the angles of 19° ± 5°as suggested by Emanuel et al. Therefore, the angles used in this experiment were 9°, 15°, 18°, 21°, and 24°. This experiment comprehensively analyzed the efficiency of the whip hit from the application of different angles and the accuracy of the hit. This study found that 19.5° ± 3° fell within range of the optimal handle angles of the foil. This range also met the optimal principle of optimal angles of 19° ± 5°for hand tool handles.
