Brisk walking does not only contribute in keeping a healthy and fit body, but it also helps increase blood flow to the brain, which lead to the reduce of Alzheimer’s disease risk, new research revealed.
The study involved 16 elderly women aged over 60 years who walked briskly for 30-50 minutes three or four times a week for 3 months. At the end of the study, the amount of blood flow to the brain in the participants increased by about 15 percent. An increased blood flow to the brain is known to reduce the risk of Alzheimer’s disease, a most common form of dementia that affects many older people.
“There are many studies suggest that exercise improves brain function in elderly people, but we don’t know exactly why the brain improves. Our study indicates it might be linked to an improvement in the supply of blood flow to the brain,” said Rong Zhang, lead researcher of the Institute for Exercise and Environmental Medicine at Texas Health Presbyterian Hospital in Dallas.
Moreover, researchers also discovered that regular brisk walking increased the women’s VO2 max (maximum capacity to transport and distribute oxygen throughout the body) by 13 percent, lowered blood pressure by 4 percent, and decreased their heart rates by 5 percent.
