摘要


先前握力相關研究主要探討徒手或穿戴手套對最大與次大握之施力、肌肉活動力、或是持續時間之影響,然而較少研究探討進行重複性握力時,徒手或穿戴手套對手部疲勞及前臂肌肉疲勞之影響程度。 本研究使用握力計及肌電訊號量測模組,收集12位男性之相關資訊,探討不同手套類型(徒手與穿戴Butyl、Hypalon與Neoprene材質)、厚度(0.015”及0.03”)及不同施力程度(25%、50%、100%最大自主施力)對手部疲勞及前臂肌肉疲勞之影響。 結果顯示,以手部疲勞而言,穿戴厚度較厚(0.03 inch)的手套會比較薄(0.015 inch)的手套的手部疲勞值較大。在前臂肌肉疲勞方面,使用頻譜與振幅合併分析方法(Joint analysis of EMG spectrum and amplitude, JASA)分析之結果顯示,以施力而言,受測者於 25%施力程度下皆能維持其25%施力,對前臂肌群並無顯著的肌肉疲勞。當進行50%與100%施力程度時,JASA方法分析之結果主要落於三、四象限,顯示前臂肌肉施力正處於力量降低與肌肉疲勞的趨勢。以厚度而言,不論厚(0.03 inch)薄(0.015 inch)皆造成前臂肌肉處於力量降低及肌肉疲勞的影響,但以厚的比例較高。以材質而言,Neoprene材質所造成的前臂肌肉疲勞最大。

Previous studies related to grip strength focused on exploring the maximum and submaximum grip strength or maximum enduration time for gripping exertions for bare and gloved hands. However, less literatures were found the effects of bare and gloved hands on hand and forearm muscle fatigue during repeated gripping exertions This study use grip dynamometer and electromyography (EMG). Twelve male participated in this experiment .Evaluates the effects of glove material (butyl, hypalon, and neoprene ) two thicknesses(0.015 and0.03 inch) and level of gripping exertion (25%, 50%, and 100% of the maximum voluntary grip exertion) on hand and forearm muscle fatigue during repeated gripping exertions . The results show that , in the hand fatigue ,the wear thicker (0.03 inch) will be relatively thin gloves (0.015 inch) glove hand fatigue larger. In the forearm muscle fatigue, use Joint analysis of EMG spectrum and amplitude (JASA), in order to force, the subjects were lower than 25% degree of force to maintain its 25 % force on the forearm muscles no significant muscle fatigue. When performing 50% and 100% force extent, JASA to analyze the results of major fall in the three, four-quadrant display forearm muscle force is reduced in strength and muscle fatigue trend. In the thickness, thickness (0.03 inch) and thin (0.015 inch) are caused by muscles in the forearm muscle fatigue strength and reduce the impact, but a higher proportion of thick. In the material Neoprene material caused by the forearm muscle fatigue max.
