In response to the growing deterioration in mental health during and after the pandemic, health organizations and the scientific community have sought effective strategies to promote well-being, especially in preparation for future global crises. Moderate and vigorous physical activity (MVPA) has been identified as a potential protective factor that enhances resilience in the face of adversity. This study aimed to analyze the moderating effect of MVPA levels on the relationship between suspected COVID-19 infection and anxiety levels in university students.</p> <p><strong>Methods and Materials:</strong> A cross-sectional, correlational-explanatory study was conducted with a sample of 922 Mexican university students (36.66% men, 63.34% women; M age = 19.97, SD = 2.92). Anxiety was measured using the Generalized Anxiety Disorder Scale (GAD-7), and MVPA levels were assessed through the short form of the International Physical Activity Questionnaire (IPAQ-s). A dichotomous-response questionnaire was used to evaluate concern about COVID-19. ANOVA and simple moderation analyses were performed.</p> <p><strong>Findings: </strong>Results indicated a significant and negative moderating effect of MVPA on the relationship between suspected COVID-19 infection and anxiety levels. Additionally, significant sex differences were found in both MVPA levels and generalized anxiety.</p> <p><strong>Conclusion:</strong> In this sample, higher levels of MVPA were associated with lower anxiety, suggesting its potential as a protective factor in adverse contexts like a pandemic.</p> https://journals.kmanpub.com/index.php/Intjssh/article/download/4422/8294
