The purpose of this study was to verify whether exercise commitment moderates the relationship between self-consciousness and social physique anxiety in women who ragularly participate in exercise. Also, the current study examined the group differences (body mass index and exercise volume) in self-consciousness, social physique anxiety, and exercise commitment. A cross-sectional survey was conducted among 249 women with the measure of self-consciousness, social physique anxiety, and exercise commitment. A sample size of 244 was employed, and ANOVA & t-test for the group difference and multiple regression analysis for moderating effect were conducted. Results indicated that the high BMI group has a more social physique anxiety than the low BMI group, and the high exercise volume group has less social physique anxiety and more exercise commitment than the low exercise volume group. The findings also demonstrated that the positive association between self-consciousness and social physique anxiety was buffered by cognitive exercise commitment, but not by behavioral commitment. Thus, it suggests that women exercising need to shift their focus on other things (i.e., exercise itself) rather than on self-things such as body image in order to alleviate social physique anxiety caused by self-consciousness.
