Can exercise actually improve one's cognitive skills? Cite examples from research to support
ANSWER:
Research clearly shows that brain plasticity is enhanced by aerobic exercise. For example, Erickson and colleagues (2009) were interested in whether aerobic exercise had any effect on the volume of the hippocampus, a brain structure involved in memory. Participants exercised on a treadmill, completed a spatial memory task, and had MRIs to determine hippocampal volume. Results indicated that higher fitness levels were associated with greater hippocampal weights, which in turn were associated with greater performance on the spatial memory task.
