Objective This paper aims to analyze the correlation between physical exercise and social anxiety of middle school students,and explore the mechanism of the chain mediation of psychological capital and self-control in this process.Methods Physical activity scale,positive psychological capital questionnaire,self-control scale and communication anxiety scale were used to investigate 843 middle school students,and chain mediation effect test and Bootstrap were used to conduct in-depth investigation.Results Physical Exercise and psychological capital of Middle School students(r=0.324,p＜0.0 1)and self-control(r=0.319,p＜0.01)were significantly positively correlated,psychological capital was strongly positively correlated with self-control(r=0.491,p＜0.01),and all three variables were significantly negatively correlated with social anxiety(r=-0.276,-0.276,-0.440;p＜0.01).The mediating effect analysis confirmed that psychological capital and self-control played an important mediating effect between physical exercise and social anxiety.There are three paths,which are the single mediating effect of psychological capital,and the effect value is-0.041.The single mediating effect of self-control was-0.023.Chain mediation of psychological capital→self-control,effect size-0.018.Conclusion Physical exercise is not only an effective strategy to relieve and prevent middle school students'social anxiety,but also intervenes indirectly through psychological capital and self-control.
