本研究目的是以承諾和認同的觀點，探討健身運動依賴和健身運動行為。以282位18-55歲之健身運動者(M=34.69; SD=9.66)為研究對象，利用健身運動行為記錄量表(Leisure Time Exercise Questionnaire, LTEQ)、健身運動承諾量表(Exercise Commitment Scale, ECS)、健身運動認同量表(Exercise Identity Scale, EIS)、修訂版健身運動依賴量表(Exercise Dependence Scale-Revised, EDS-R)進行研究。研究結果發現健身運動依賴和承諾有非常高的相關，也和健身運動認同有非常高的相關；以結構方程模式進行預測模試驗證，發現健身運動認同和必須要的承諾透過健身運動依賴預測激烈健身運動行為，而想要的承諾則無法預測健身運動依賴與健身運動行為；最後，不同依賴型態進行的差異分析中，僅發現風險依賴組在激烈運動行為上高於無依賴有症狀組和無依賴無症狀組。本研究結論指出健身運動認同及健身運動承諾對於健身運動行為包含直接與間接影響，且健身運動依賴對健身運動行為有負面影響，健身運動指導者和專業人士需深入瞭解健身運動依賴的前置因素和相關心理，並據以適當的輔導，以達到規律健身運動的最大效果。
The purpose of this research was to adopt the commitment and identity perspectives to examine the relationship between exercise dependence and exercise behavior. Two hundred and eighty-two regular exercisers, aged from 18 to 55 years (34.69±9.66) were participated in this study. All the subjects were attended to Leisure Time Exercise Questionnaire (LTEQ), Exercise Commitment Scale (ECS), Exercise Identity Scale (EIS) and Exercise Dependence Scale-Revised (EDS-R). Results of this research showed that exercise dependence correlated with exercise commitment and identity. In addition, Structural Equation Modeling (SEM) analysis found both exercise identity and have-to-commitment directly and indirectly predicted exercise dependence and vigorous exercise behavior. However, want-to-commitment failed to predict dependence and exercise behavior. Moreover, risk-dependence exercisers had higher vigorous exercise behavior than non-dependence symptomatic and non-dependence asymptomatic exercisers. This study concludes that both exercise identity and exercise commitment have direct and indirect influence on exercise dependence and exercise behavior. Additionally, exercise dependence may cause negative effect on exercisers. Therefore, exercise instructors and professionals need to deeply understand the antecedents and related variables of exercise dependence in order to develop a better exercise program and achieve better effects of exercise.
