Physical activity and caloric expenditure after adolescent concussion: a comparison with uninjured controls

Adolescents after recent concussion demonstrated lower PA and expended fewer calories than uninjured controls, indicating that it may take several weeks after concussion to resume PA levels similar to uninjured peers. Our results may reflect participants following concussion guidelines/physician guidance to gradually increase PA during concussion recovery as tolerated without symptom exacerbation, leading to less PA engagement compared to controls. Further research into energy needs after concussion may inform therapeutic targets to facilitate recovery.
