A stratified random sampling method was used to select 981 college students from different provinces and universities for a questionnaire survey. Statistical methods, including confirmatory factor analysis, regression analysis, and the Bootstrap method, were employed for data analysis.ResultsExercise participation significantly and negatively predicted college students' feelings of self-deficiency. Social support exhibited a significant mediating effect between exercise participation and self-deficiency. Furthermore, the three dimensions of social support—subjective support, objective support, and support utilization—showed significant indirect effects. The mediation pathways were as follows: exercise participation → subjective support → self-deficiency, exercise participation → objective support → self-deficiency, and exercise participation → support utilization → self-deficiency.ConclusionExercise participation significantly reduces feelings of self-deficiency among college students, either directly or indirectly through social support. In the future, universities can help mitigate students' self-deficiency and promote their physical and mental wellbeing by optimizing physical activity spaces and constructing social support networks from the perspectives of exercise participation and social support.
