本研究目的在探討參與重量訓練一般男性之追求肌肉發達驅力、社會體型焦慮與運動依賴癥候的關係，並瞭解社會體型焦慮調節追求肌肉發達驅力與運動依賴關係的效果。自南部某大型連鎖健身中心重量訓練區，以隨機抽樣法選取188位自願者為研究對象，平均年齡為30.1（SD = 7.3）歲。徵求同意後，讓其填寫追求肌肉發達驅力量表、社會體型焦慮量表及運動依賴量表。分析結果為：追求肌肉發達驅力與戒斷、耐受性、持續性、減少其他活動、時間及意圖影響等運動依賴癥候呈正相關；社會體型焦慮則與戒斷、耐受性、缺乏控制、減少其他活動及意圖影響等運動依賴癥候呈正相關。社會體型焦慮調節行為取向與缺乏控制、減少其他活動及意圖影響的效果達顯著水準，事後比較顯示：在高體型焦慮群體中，行為取向對減少其他活動有較高的預測力（17%）。本研究結論指出追求肌肉發達驅力是影響運動依賴癥候發生的因子，倘若鍛鍊肌肉行為出現焦慮感受，更會增加發生的風險。

This study aimed to understand the relationship among drive of muscularity, social physique anxiety, and exercise dependence symptoms in male weight trainers. Furthermore, the moderating effect of social physique anxiety in the relationship between drive of muscularity and exercise dependence symptoms was also investigated. By a random sampling method, 188 volunteers were selected as participants from the weight training fitness center in Kaohsiung. After obtaining the informed consents, participants were administered by the drive of muscularity inventory, social physique anxiety inventory and exercise dependence inventory. The results were as follows: There were positive correlations among drive of muscularity and withdrawal, tolerance, continuance, reductions in other activities, time, and intention effect of exercise dependence symptoms. Positive correlations were also observed among social physique anxiety and withdrawal, tolerance, lack of control, reductions in other activities, and intention effect of exercise dependence symptoms. The moderating effect of social physique anxiety on the relationship between behavioral approach and lack of control, the reductions in other activities, and intention effect of exercise dependence symptoms were found to be significant in this study. The post hoc comparison indicated that the behavioral approach had more predictive power (17%) on reductions in other activities for the high physique anxiety groups. Our study concludes that drive for muscularity could be the vital factor of exercise dependence in male weight trainers.
