Benefits and Barriers of Combined Aerobic and Strength Training on Medical Students' Psychological Wellbeing.

Background: While physical activity is associated with improved mental health, many medical students fail to meet recommended exercise guidelines. Understanding how exercise relates to wellness indicators in this population may help guide the development of targeted wellness interventions that promote sustainable health behaviors. Objectives: This study aimed to: (1) assess the prevalence and characteristics of physical activity among medical students; (2) examine associations between exercise behaviors and wellness indicators. Methods: A cross-sectional survey was administered to M.D. students at a U.S. medical school. The survey included validated measures to assess exercise habits, burnout, stress, quality of life, social support, and sleep. Statistical analyses included descriptive statistics, t-tests, Fisher's exact tests, and multiple linear regression. Results: Among 82 respondents, only 34.2% met both aerobic and strength training CDC guidelines. These students reported significantly lower stress, higher quality of life, and greater friend support compared to peers who met neither guideline. Individual exercise was associated with lower stress, less burnout, and higher quality of life than group exercise, despite the latter being linked to greater social support. Conclusions: In advocating for interventions that support student wellbeing and the development of sustainable health habits, medical schools can help contribute to long-term student wellness.
