While aerobic exercise benefits cognition in adults, its impact on the adolescent brain is less understood. This study examined associations between aerobic fitness, learning and memory, and neural mechanisms in 34 male adolescents (ages 15–18) using behavioral tasks and MRI. Higher fitness was linked to improved spatial learning and larger hippocampal volumes, though mediation was not supported. Functional imaging revealed differences in default mode network activity and compensatory recruitment in lower-fit youth. Findings suggest aerobic exercise influences hippocampal structure and memory-related neural function during adolescence.
