There is evidence to suggest that exercise can improve memory. The University of Illinois found that regular aerobic exercise improved cognitive function and memory in adults aged 55 to 80. The researchers believe that the increased blood flow and stimulation to the brain due to exercise leads to the improvement in memory.
Another study published in the journal Neuropsychology found that aerobic exercise programs led to significant improvements in cognitive function and memory in older adults with mild cognitive impairment. These findings suggest that regular exercise may help to improve memory in older adults.
