Questionnaire model fitting indicators.

Objective
This study explores the relationships among physical exercise, social support, and feelings of inferiority among college students, with a particular focus on the mediating role of social support. Using a sample of Chinese college students, the results demonstrate that physical exercise significantly reduces feelings of inferiority, both directly and indirectly through enhanced social support.
Method
Pearson correlation analysis confirmed the positive correlation between physical exercise and social support, while also showing that both physical exercise and social support negatively correlate with feelings of inferiority. Structural equation modeling further supported the hypothesized relationships, revealing that the mediation pathway through social support accounted for 51.95% of the total effect. Additionally, multi-group invariance testing indicated that these relationships were consistent across genders, underscoring the universal applicability of the model.
Results
The findings highlight the dual pathways through which physical exercise alleviates feelings of inferiority: by fostering personal competence and enhancing social resources.
Conclusion
This study emphasizes the importance of integrating physical exercise and social support, providing evidence-based intervention recommendations for improving students’ mental health. By validating the dual-pathway model, the research offers theoretical support and practical significance for promoting students’ mental health through physical exercise and social support.
