Effects of Acute Aerobic Exercise and Task Repetition on the Neural Correlates of Executive Function in Young and Older Adults: A Crossover fMRI Study

This study investigates how acute aerobic exercise and task repetition influence brain activity related to executive function in young and older adults during a task-switching paradigm. The results indicate that older adults show greater task-related brain activation compared to younger adults, and while task repetition reduces activation across both age groups, acute aerobic exercise appears to preserve certain neural functions without significant behavioral improvements. Overall, the findings suggest that exercise may have a modest impact on executive function neural correlates, particularly in older adults.
