Researchers find high-intensity exercise improves memory in seniors

Researchers at McMaster University who examine
the impact of exercise on the brain have found that high-intensity workouts improve memory
in older adults. The study, published in the journal Applied
Physiology, Nutrition and Metabolism, has widespread implications for treating dementia,
a catastrophic disease that affects approximately half a million Canadians and is expected to
rise dramatically over the next decade. Researchers suggest that intensity is critical. Seniors who exercised using short, bursts
of activity saw an improvement of up to 30% in memory performance while participants who
worked out moderately saw no improvement, on average.
