[Sport and exercise therapy for burnout and fatigue-a narrative review].

Burnout and fatigue have overlaps in their symptoms. The common denominator is exhaustion. Physical activity has been shown to be a risk-reducing factor for the development or manifestation of symptoms. There is also evidence of an effect of physical activity in the acute phase, rehabilitation, and aftercare of burnout as well as in diseases that are associated with the occurrence of fatigue and their treatments.In burnout research, physical activity is considered a risk-reducing factor and coping strategy, but there are no specific exercise recommendations with regard to symptom severity. In the area of tiredness/fatigue, the overall picture is inconsistent: there are already targeted recommendations for exercise therapy in a multimodal approach for individual clinical pictures. For example, there is high evidence for the use of appropriately dosed physical activity in cancer patients in adjuvant therapy and aftercare. Other diseases associated with the occurrence of fatigue, such as long- and post-COVID, have not yet been sufficiently researched to make clear statements about a dose-response relationship. For some diseases, there are already targeted recommendations for exercise therapy in a multimodal approach.This paper aims to provide an overview of the current state of exercise research in burnout and fatigue and thus, on the one hand, make therapy recommendations for practitioners and patients, and on the other hand, shed light on the evidence in those areas in which there are (still) no general and individualized exercise recommendations and guidelines.
