Abstract Objective To explore correlations among physical exercise, sports friendship, physical exercise involvement, and school adaptation in medical freshmen, and investigate the chain mediating effects of sports friendship and physical exercise involvement in physical exercise and school adaptation. Methods A total of 888 medical freshmen（290 males and 598 females）were enrolled in group psychological measurement by using physical exercise rating scale, Chinese college student adaptation scale, youth sports friendship quality scale, and college student physical exercise investment self-evaluation scale. Single factor analysis of variance, chain mediation test, and Bootstrap analysis were used to analyze data. Results The level of physical exercise had significant effects on school adaptation, sports friendship, and physical exercise involvement in medical freshmen. There were significant positive correlations between physical exercise and school adaptation（r=0.40, P<0.001）, sports friendship（r=0.19, P<0.001）, and physical exercise involvement（r=0.47, P<0.001）. Sports friendship and exercise involvement played completely mediating roles in the relationship between physical exercise and school adaptation. The mediating effect included three paths: the single mediating effect of sports friendship, the single mediating effect of physical exercise involvement, and the chain mediating effect of sports friendship and exercise involvement, which accounted for 45%, 32% and 13% of the total effect, respectively. Conclusion Physical exercise is significantly correlated with the level of sports friendship and physical exercise involvement in medical freshmen. Physical exercise indirectly affects the school adaptation of medical freshmen through the chain mediating effects of sports friendship and physical exercise involvement.
