Maintenance of Mental Health: The Role of Physical Activity Among Young Adults

<b>Background:</b> Young adults, particularly university students, are at increased risk for psychological distress and burnout. Regular physical activity is widely recognized as a protective factor for mental health. This study aimed to compare physically active and inactive college students in terms of perceived stress, well-being, burnout, and resilience. <b>Methods:</b> A cross-sectional online survey was conducted among Hungarian university students (N = 264; 24.6% male; mean age = 24.21 years). Participants completed validated questionnaires assessing physical activity habits, perceived stress, resilience, and academic burnout. <b>Results:</b> Results showed that students engaging in regular physical activity reported significantly lower levels of perceived stress (Cohen's d = 0.288) and burnout (Cohen's d = 0.277), and higher resilience (Cohen's d = 0.258) and well-being (Cohen's d = 0.322) compared to their inactive peers. Correlation analyses confirmed strong associations between lower stress, reduced burnout, and greater resilience and well-being. Cluster analysis revealed two distinct psychological profiles: one characterized by higher mental hazards (stress and burnout) and the other by higher mental assets (resilience and well-being). Physical activity was strongly associated with membership in the mentally resilient cluster. <b>Conclusions:</b> These findings underscore the mental benefits of remaining physically active and highlight the importance of physical activity within university settings as a key strategy to enhance resilience, reduce academic burnout, and support the maintenance of mental health among young adults. However, the cross-sectional design, reliance on self-report measures, and convenience sampling limit causal interpretation and generalizability.
