目的：驗證計畫行為理論應用於預測健身運動參與者行為傾向模式。方法：研究應用問卷調查法收集研究參與者樣本資料，以高雄地區BEING sport統一健身俱樂部高雄巨蛋館的健身運動參與者為研究對象，於2017年11月10日至20日，以便利抽樣方式針對對研究參與者發放300份問卷，扣除無效問卷14份，共得有效問卷286份，有效問卷率95.3%。回收問卷資料以Amos21.0進行收斂效度、區別效度、模型適配度與交叉效度考驗等結構方程模式分析。結果：研究結果顯示健身運動參與行為傾向模式中，態度對行為傾向路徑係數.31*達顯著影響；主觀規範對行為傾向路徑係數.28*達顯著影響；行為控制知覺對行為傾向路徑係數.29*達顯著水準，研究假設均獲得支持。結論：(一)健身運動參與行為傾向模式中，研究參與者之態度選項中以保持身材及學習知識最具影響力，而藉由提升參與健身運動之態度，會正向影響參與健身運動之行為傾向；(二)健身運動參與者行為傾向模式中，研究參與者之重要參考群體中以同學對之影響力最大，而藉由提升參與健身運動之主觀規範，會正向影響參與健身運動之行為傾向；(三) 健身運動參與者行為傾向模式中，研究參與者之行為控制知覺中以有無同伴共同參與健身運動之影響力較大，而藉由提升參與健身運動之行為控制知覺，會正向影響參與健身運動之行為傾向。

Purpose: The purpose of this study was to verify the applicability of the theory of planned behavior to the prediction of behavioral tendencies of participants in fitness exercise. Method: Sample data were collected by applying questionnaires method in the study, take exercise participants of BEING Sport Fitness Clubs Kaohsiung Dome Hall in Kaohsiung area as the research object. From November 10 to 20, 2017, a total of 300 questionnaires were sent to the subjects with convenience sampling, and 14 invalid questionnaires were deducted, 286 valid questionnaires were obtained, and the effective questionnaire rate was 95.3%. The recovery questionnaire data were analyzed by Amos21.0 statistical software, with the structural equation models of convergence validity, discriminant validity, model fitness degree and cross validity test, etc. Results: The results show that attitude had a significant influence on the behavior tendency path coefficient.31* in the behavior orientation pattern of fitness exercise; Subjective norms had a significant impact on the behavior tendency path coefficient.28*; Behavior control perception had a significant impact on the behavior tendency path coefficient.29*, research assumptions are supported. Conclusions: (I) In the behavioral tendency mode of fitness exercise participants, subjects' attitude choices are most influential on keeping shape and learning knowledge, and improving their participation in fitness exercise will positively affect the behavioral tendency of participating in fitness exercise. (II) In the behavioral tendency mode of fitness exercise participants, among the important reference group of the subjects, the most influential factor is the student's influence, and by improving the subjective norm of participating in the fitness exercise, it will positively affect the behavioral tendency of participating in the fitness exercise. (III) In the behavioral tendency mode of fitness exercise participants, participants' behavior control perception was mostly influenced by their partners' participation in fitness exercise, and improving their participation in exercise behavior control perception will positively affect the behavioral tendency of participating in fitness exercise.
