In a small group of men and women ages 60 to 80 it was found that those who did 3 hours of aerobics per week for ten consecutive years had much less abnormal twisting of the blood vessels in their brain, reflecting brain circulation patterns of younger adults.
The research was done using non-invasive magnetic resonance (MR) angiography, which could examine the number and shape of blood vessels in the brain. The narrowing and twisting of blood vessels is a common feature of the aging brain – something these aerobically fit seniors were able to significantly prevent.
