本研究之目的有二：（一）比較不同性別大專木球選手知覺運動動機氣候與運動自信心來源之差異；（二）探討大專木球選手知覺運動動機氣候與運動自信心來源之間的相關。方法：以中華民國100年全國大專院校運動會木球項目運動員為研究對象，研究工具為使用「運動動機氣候量表」與「運動自信心來源量表」，以立意抽樣方式抽取209位，回收經整理後得有效問卷195份（回收率為93.3%，男性84位與女性111位）。其資料分析以t檢定。（t-test）與皮爾遜積差相關分析（Pearson product moment correlation）及典型相關分析（canonical correlation analysis）等統計方法進行分析。結果：1、不同性別大專木球選手在運動動機氣候與運動自信心來源達顯著差異；2、大專木球選手在運動動機氣候與運動自信心來源差異達顯著相關存在，而在運動動機氣候的努力進步和運動自信心來源的技術知覺相關最高。
