本研究主要目的乃在探討性別、有無穿戴護腕與不同捏力型態(pulp3, pulp2, chuck, and lateral)於持續施力中對捏力績效之的。績效指標包含最大意施力(maximal volitional contraction MVC)、持續時間(maximal acceptable sustaining time MAST)、總力量輸出(total force generation TFG)與平準化施力水準(normalized exertion level NEL=TFG/(MAST×MVC)×100)之影響。受試者包含12位男位與12位女性，並採用巢狀因子(nested-factorial design)之實驗設計方法進行實驗與資分析。變異數分析(ANOVA)結果指出除了MAST外，性別對其他所有績效指標皆有顯著影響；相關資料意味著女性在施力麥果與效率上似乎不如男性。而捏力型態則對所有之績效指標有顯著影響，而且能夠產生較大MVC者亦能有較佳之MAST、TFG，及以NEL。因此，依據上述績效指標，chuck與lateral為兩種較被建議使之捏力型態，而pulp 3則否。有趣的是，牙戴護腕與否，僅會縮短施力時間(MAST)，對其他績效則無顯著影響。

　　　　　Present study intends to investigate the effect of wrist splints, pinch types (pulp3, pulp2, chuck, and lateral), and gender on pinching performance measured during a sustaining exertion, including maximal volitional contraction (MVC), maximal acceptable sustaining time (MAST), total force generation (TFG) over the MAST, and the normalized exertion level (NEL), defined as [TFG/(MAST×MVC)]×100. Twelve males and 12 females participated in this experiment, and a balanced nested-factional design was employed. The ANOVA results indicate that the gender effect is significant in all areas but MAST, and this finding seems to imply that females exert less effectively and efficiently than males do. Pinch types affect all four responses significantly, and pinch types with higher MVC values have higher MAST, TFG, and NEL values as well; consequently, the two pinch types of chuck and lateral are recommended, but pulp 3 in not. Of interest, wearing splints did not affect all responses but significantly shortened the MAST value.
