目的：探討柔道選手知覺教練效能與團隊承諾及專業承諾的關聯性。方法：以國內大專院校體育科系公開組柔道運動員，以及高中職重點培育柔道選手學校，合計共20個團隊，513位選手爲樣本，進行因素分析、相關分析及階層迴歸分析。結果：在控制知覺教練支持與其他控制變項的影響後，知覺教練效能與運動員團隊承諾及專業承諾皆有顯著正向關聯。結論：柔道選手所知覺的教練效能愈高，對於運動員的團隊承諾與專業承諾均可能有著正向的影響效果；最後，爲使本研究更落實在教練訓練上的應用，將對教練效能與團隊承諾及專業承諾的結果不同提出討論，並對未來研究方向提出建議。

Purpose: This study investigated the relationship between the perceived coaching efficacy, team commitment and professional commitment of Judo team members. Method: Surveyed 20 teams and analyzed data from 513 Judo, athletes from the physical education departments of several universities and senior high schools across Taiwan.
