Moderate aerobic exercise helps boost blood flow to the brain in older women, new research reveals.
The findings offer insight into how vascular health affects brain health, lead researcher Rong Zhang, of the Institute for Exercise and Environmental Medicine at Texas Health Presbyterian Hospital in Dallas, explained.
How the study was done
Zhang and the other researchers used Doppler ultrasonography to chart blood flow in the women's carotid arteries, which are located in the neck and supply the brain with crucial glucose and oxygen-rich blood. The blood also gets rid of brain metabolic wastes such as amyloid-beta protein (implicated in Alzheimer's disease) that have been released into the brain's blood vessels.
