Introductionː Preferences for certain times of day to perform daily activities have been the focus of several investigations. Individuals with evening preference exhibit higher scores for depressive symptoms and less involvement in physical activities compared to morning and intermediate chrono types. On the other hand, physical activity is an intervention that has shown great promise in alleviating symptoms of Major depressive disorder.
Evidence Acquisitionː This study aimed to perform a narrative review of the available evidence of possible relationships between chrono type, depression and physical activities. The Electronic searches of the published literature were performed in the databases National Library of Medicine National Institutes of Health, in 2019, for the last five years in the adult population. The results were grouped into three categories, chrono type and depression in adults; depression and exercise/physical activity in adults; chrono type and exercise/physical activity/sport in adults.
Evidence Synthesisː the importance of physical activities in combating depression is quite evident in the literature, showing an inverse relationship between the level of physical activity and depressive symptoms.
Conclusionsː However, many studies on depressive individuals do not identify the chrono type as an important tool to integrate chronobiological aspects of human behavior in the treatment of this disease. This review provides evidence for the scarcity of studies on the relationship between chrono type, depression and physical activity.
