Unveiling the role of physical exercise in promoting social interaction and adolescents' psychological prosperity.

The existing research on physical exercise mainly focuses on the effect of exercise intervention, and pays less attention to the role of physical exercise in social interaction. From the perspective of social interaction, this study uses social network theory to explore explored how physical exercise affects adolescents' psychological prosperity through relationship network construction, and examines the moderating effect of proactive personality with the help of personality trait theory. The empirical analysis of 652 paired data from multiple sources and time points revealed that physical exercise can significantly promote adolescents' relationship network construction. Adolescents' relationship network construction has a significant positive effect on their psychological prosperity, and can play a mediating role between physical exercise and psychological prosperity. Proactive personality can not only moderate the direct relationship between physical exercise and adolescents' relationship network construction, but also moderate the indirect relationship between physical exercise and adolescents' psychological prosperity via relationship network construction. These findings reveal the role of physical exercise in promoting social interaction and adolescents' psychological prosperity, helping people to have a more comprehensive understanding of the impact of physical exercise and providing theoretical guidance for the realization of adolescents' psychological well-being.
