The aim of the present study was to examine the impact of the changes in physical self-concept induced by exercise participation on the changes in global self-esteem and mental well-being using a structural model analysis. A total of 189 university students in Seoul, Korea, participated in the present study for two waves. The participants responded through a survey measuring physical self-concept, self-esteem, and mental well-being before and after a six-week exercise course. Regression analysis was used to calculate the amount of change in each variable, and the calculated residual scores were used for correlation analysis and structural model analysis. The amounts of changes in the variables are significantly correlated with each other and there was a complementary mediating effect of the changes in self-esteem on the pathway from the changes in physical self-concept to the changes in mental well-being. Physical self-concept changed by exercise participation might directly and positively influence mental well-being, and it can indirectly influence the changes in mental well-being via the improvement of self-esteem.

参加运动引起的身体自我概念变化对自尊和心理健康变化的影响

本研究的目的是使用结构模型分析研究运动参与引起的身体自我概念变化对整体自尊和心理健康变化的影响。韩国首尔共有189名大学生参加了本次研究，历经了两次浪潮。参与者通过一项为期六周的锻炼课程前后的身体自我概念，自尊和心理健康的调查来回答。回归分析用于计算每个变量的变化量，计算出的残差得分用于相关性分析和结构模型分析。变量的变化量彼此之间显着相关，自尊的变化对从身体自我概念的变化到心理健康的变化的路径具有互补的中介作用。运动参与所改变的身体自我概念可能直接和积极地影响心理健康，并且可以通过提高自尊而间接影响心理健康的变化。
