Abstract

Physical exercise has been linked to improvements in cognitive function, particularly executive control in older adults. However, the optimal intensity of aerobic training for cognitive benefits remains debated. This study randomly assigned middle-to-old age adults to moderate-intensity, vigorous-intensity, or a control (non-exercise) condition over a 12-week training program. Participants completed a battery of executive function tests — including Stroop interference, trail-making, and working memory tasks — before and after the intervention. Both exercise groups showed significant improvements relative to controls, but vigorous-intensity training produced larger gains on inhibitory control measures. Moderate-intensity training showed advantages for cognitive flexibility. These findings indicate that exercise intensity differentially recruits neuroplastic mechanisms supporting distinct executive function components, informing exercise prescription for healthy aging.
