本研究主要在探討青少年運動行為調節與健身運動自我效能之關係。為達研究目的依據文獻探討分析，採用「運動行為調節量表」(蔡俊傑，2009)、「健身運動自我效能量表」(蔡俊傑，2010)作為研究工具，並以臺灣地區青少年為樣本，共抽取1300位國中生進行問卷調查。統計分析方式包含兩部分：第一部分為基本資料與研究變項之平均數差異考驗與單因子變異數分析；第二部分主要分析利用積差相關、逐步迴歸解釋運動行為調節與健身運動自我效能之關係。本研究所得之主要結果如下：
1.運動行為調節因背景變項的不同，多數層面具有差異存在。
2.健身運動自我效能因背景變項的不同，多數層面具有差異存在。
3.運動行為調節與健身運動自我效能具顯著相關性存在。
4.運動行為調節各層面對健身運動自我效能之逐步迴歸分析，以「整合調節」具有最高之解釋力。

　　The main purpose of this study is to explore the relationship between the youth sports behavior regulation and exercise self-efficacy. Based on literature survey, the instruments were Behavioral Regulation in Sport Questionnaire(Ju-Je Tsai,2009),and Youth Exercise Self-Efficacy Questionnaire(Ju-Je Tsai,2010). The sample was 1300 adolescents in Taiwan. Data were analyzed in two parts: first part included descriptive statistics, t-test, one-way ANOVA and second part included Pearson correlation and stepwise regression.
The major results of the study are:
1.Different background variables make the behavioral regulation in sport vary greatly in some aspects.
2.Different background variables make the exercise self-efficacy vary greatly in some aspects.
3.There are significant relationships between the behavioral regulation in sport and exercise self-efficacy .
4.According to stepwise regression analysis, among all aspects of the behavioral regulation in sport and exercise self-efficacy, the ’integrated regulation’ has the most explanation on the predictability of the exercise self-efficacy.
