本研究的主要目的在探討目標承諾對排球低手傳球技能之影響。以以私立南開技術學院九十二學年度第二學期四技一、二年級78名男學生為研究對象，依Orlick所編寫的目標承諾量表，將學生平均分配成高、低兩個不同目標承諾組別，分別進行為期四週，每週50分鐘的排球低手傳球教學。以重覆量數雙因子變異數分析進行處理，研究結果發現：（一）在不同目標承諾組方面，其主要效果具有顯著差異，並且高目標承諾組在排球低手傳球表現上比低目標承諾組好。（二）在練習週次方面，其效果亦達顯著差異，並且隨著練習週次的增加而進步。（三）在不同目標承諾組與練習週次方面，其具有交互作用，高目標承諾組有大幅度的進步，而且在第三週後，其排球低手傳球表現顯著優於低目標承諾組。
The main purpose of this study was to discuss how different goal commitments affect the skill of volleyball underhand passing. 78 Nan-kai junior college students were served as the subjects. 78 subjects were divided into 2 groups (high and low goal commitments) and accepted 4 weeks of volleyball underhand ball passing training. Repeated Measures Two-way ANOVA was applied to process data. The result were as followed: 1. There was statistical significance between groups. The high goal group was showing better skill comparing with low goal group. 2. There was statistical significance between the lengths of training. The longer the group accepted training, the better result of performance it became. 3. The high goal group was improving greatly on the skill of underhand passing, especially after the third week, the performance was way better than low goal group.
