Cortical Structures Associated With Sports Participation in Children: A Population-Based Study

We studied cortical morphology in relation to sports participation and type of sport using a large sample of healthy children (<i>n</i> = 911). Sports participation data was collected through a parent-reported questionnaire. Magnetic resonance scans were acquired, and different morphological brain features were quantified. Global volumetric measures were not associated with sports participation. We observed thicker cortex in motor and premotor areas associated with sports participation. In boys, team sports participation, relative to individual sports, was related to thinner cortex in prefrontal brain areas involved in the regulation of behaviors. This study showed a relationship between sports participation and brain maturation.
