The results showed that physical exercise had a significant positive predictive effect on the participants' subjective well-being. Furthermore, social networks and a sense of hope mediated the association between physical exercise and subjective well-being. Physical exercise indirectly promoted subjective well-being by enhancing social networks and a sense of hope. However, the indirect effect of a sense of hope on the association between physical exercise and subjective well-being was greater than that of social networks. The results of this study revealed the internal mechanism of the effect of participation in physical exercise on the improvement of subjective well-being, which is of great significance for formulating relevant policies and plans to further improve Chinese residents' well-being.
