Exercise for the promotion of mental health : Putative mechanisms, recommendations, and scientific challenges

The idea of applying various forms of physical activity for the betterment of physical health and the reduction of chronic medical conditions is ubiquitous. Despite evidence of successful applications of physical activity for improvement of mental health dating back to antiquity, it has until recent years remained unconventional to consider exercise as an intervention strategy for various mental health conditions. The past two decades, however, have seen a relative explosion of interest in understanding and applying various programs and forms of exercise to improve mental health. Here, our purpose is to provide a comprehensive and updated overview of the application of exercise as a strategy for improving mental health. In the present paper we first summarize contemporary research regarding short-and long-term impacts of exercise on mental health. Then an overview of the putative mechanisms and neurobiological bases underpinning the beneficial effects of exercise is provided. Finally, we suggest directions for future research as well as a series of concrete recommendations for clinicians who wish to prescribe physical activity as part of patient mental health management.& COPY; 2023 L'Encephale, Paris.
