Abstract
Background: Medical resident burnout is a critical threat to healthcare workforce sustainability, with physical activity (PA) posited as a protective factor. This bibliometric analysis maps the global research landscape on this topic from 2005 to 2025. Methods: Systematic search of the Web of Science Core Collection identified 110 relevant English-language articles. Performance analysis and scientific mapping were conducted using R and VOSviewer. Results: The field saw an annual growth rate of 3.35%, with a peak of 16 publications in 2019. The United States was the dominant contributor, accounting for 68% of the total output. Analysis identified several major thematic areas, including stress and behavioral factors, occupational mental health, and institutional support mechanisms. The findings reveal a rapidly growing but geographically concentrated body of research, underscoring a significant gap in globally representative evidence. Conclusions: This analysis provides a foundational map for future research, underscoring the need for institutional wellness programs incorporating PA, international collaborative studies, and policy-level interventions. We conclude that integrating physical activity is not a luxury but a critical strategy for healthcare system sustainability.
