摘要
本研究目的在於探討性別、手腕姿勢、握距及手套對MVC及施力時間之影響，並將實驗以二部分進行之。實驗設計均採巢狀因子設計。實驗一因子包含性別、受試者（男、女生各十五名，伏集於性別）、握距（共有1.5英吋、2.0英吋、2.5英吋、3.0英吋）、手腕姿勢（不偏N、最大伸展ME、最大屈曲MF）等四個。實驗結果顯示所有主效果與兩因子間交互作用均對MVC有顯著影響。在任一握距或手腕姿勢下，男性施力皆大於女性；男性平均最大握力為26公斤，女性為15公斤，約為男性的58%。另外，男女在手腕姿勢為不偏時，皆具較佳之MVC。而較佳的握距水準依序為2.0＞1.5＞2.5＞3.0。在到達不同施力程度所需時間部份，就性別而言，於T70-80往後的各區段且任一種姿勢之下，男性的施力時間均長於女性，男性在後面區段（如T80-90、T90-100）所需的時間較女性為長；手腕姿勢在區段T70-80（含）之後的各施力區段中，最大屈曲係為施力時間最長的手腕姿勢，不偏的施力時間則恆短於其他手腕姿勢。而握距在區段T80-90且手腕姿勢為最大屈曲時，3.0英吋為施力時間較長之握距，當區段T90-100且手腕姿勢為不偏及最大伸展時，則以2.0英吋為施力時間較長的握距水準。亦即，區段T70-80之後，握距水準間確實因各區段中不同的手腕姿勢而各有其明顯的差異。另外，在施力區段方面，區段T60-70及/或T70-80之後的區段裡所需的時間顯著大於之前的區段，特別是T90-100。實驗二因子包含性別、受試者（男、女生各十名，伏集於性別）、手套（空手、棉一層、棉二層）等三個。實驗結果顯示僅所有主效果是顯著的，交互作用則無。不論空手或是戴何種水準的手套，男性平均最大的握力均大於女性。且戴手套確實會致握力減低。在施力區段方面，我們發現不論實驗一、二，區段T70-80之前的區段間均無顯著差異，往後的各施力區段則具顯著的差異，尤以區段T90-100所需時間顯著的長於其他區段。

ABSTRACT
The aim of this study was to evaluate the effects of grip span,maximal wrist extension/flexion,and gloves on grip strength and time needed to reach different levels of exertion. 30 subjects participated in Eexperiment 1in which MVC and time needed to reach different levels of exertion were measured using 4 levels of grip span and 3 levels of wrist posture.results indicate that femal performed MVC was 58% of male and the greatest MVC was occurred on neutral. When posture changed from maximum flexion, through neutral, to maximum extension, the span with better MVC output seems to move from a smaller span to a larger span. as T-level, it took more time on the later period of exertion. 20 subjects participated in Eexperiment 2 in which MVC and time needed to reach different levels of exertion were measured using 3different kinds of gloves.results indicate that femal performed MVC was 55% of male and wearing gloves decreased the MVC of grip .
KEYWORDS：Grip strength、maximum volitional contraction、Grip span、maximum wrist extension/flexion、gloves
