摘要 本研究以側化偏好的原理,探討不同慣用手者與運動員其左右手對手部運動知覺表現的影響。以20名慣用右手與20名慣用左手之國中男生,以及20名慣用右手之單手持拍運動員,共60名為受試參加者。實驗過程包含手部力量控制與下手拋球準確性兩種測驗。實驗中,不同慣用手組之手部運動知覺成績表現應用二因子變異數分析統計處理;運動員組之左右手運動覺成績表現則採重複量數t考驗之統計處理。研究結果發現:(一)不論慣用右手組或慣用左手組,其左手的運動覺成績表現均優於右手的運動知覺成績表現。(二)運動員組左手與右手運動知覺成績表現沒有差異,實驗結果顯示,經由長時間的練習,有助於增進練習用手運動知覺的成績表現。
Abstract The study basis on lateral preference principle was to investigate (1) the different lateral preference at upper limb on kinesthetic sense, and (2) the difference on kinesthetic sense between right hand and left hand in athletes. 20 right-handedness, 20 left-handedness junior high school male students, and 20 right-handed university male athletes who had used one hand to hold racket were served as participates. The experimental process included upper limb force control and under arm's throwing accuracy. Two-way ANOVA mixed design and repeated measures t test Were utilized for the statistical analysis from the obtained data. The results indicate that: (1) No matter which dominant hand the participates' were usually prefered, both right-handedness and left-handedness groups, the kinesthetic sense on left hand was better than right hand. (2) Long time training could increase upper limb kinesthetic sense.
