目的：本研究旨在探討柔道選手社會支持、流暢體驗與幸褔感之關係，並試圖構建其因果模式。方法：以全柔道選手作為研究的對象，每位選手均施測社會支持量表、流暢體驗量表及幸褔感量表，共獲得有效樣本378份，所得資料以皮爾遜積差相關及結構方程模式進行統計分析。結果：柔道選手的社會支持對流暢體驗有直接影響，並且透過流暢體驗而對幸褔感造成間接影響。因此可知流暢體驗在因果模式扮演著中介之角色。結論：本研究建議柔道教練應創造更多的社會支持情境，加強選手的流暢體驗才能讓選手產生更多的幸褔感，以提升柔道選手運動表現。

The purpose of this study is two-fold: 1) to discuss the relationship among Judo athletes' social support, fluent experience, and satisfaction and 2) to model them from a cause-and-effect perspective. The samples are student Judo athletes in Taiwan, who receive three kinds of questionnaires for social support, fluent experience, and satisfaction respectively. A total of 378 samples were valid, and data were statistically tested by Pearson Product Moment (PPM) correlation and SEM (Structural Equation Modeling). The results indicate that social support has a significant and positive impact on athlete's fluent experience, which has a subtle effect on satisfaction. Fluent experience, therefore, plays a mediating role in the cause-and-effect light. This study suggests that Judo coaches should create an environment of immense social support so that student athletes' fluent experience can be enhanced and great satisfaction can be achieved.
