Researchers at New Mexico Highlands University discovered that walking sends pressure waves through the arteries and increase blood supply to the brain.
The research used non-invasive ultrasound to measure the internal carotid artery blood velocity waves and arterial diameters to obtain hemispheric cerebral blood flow to both sides of the brain of 12 healthy adults during standing test and walking.
They found that walking produces pressure waves in the body that increases blood flow to the brain.
Brain blood flow depends directly on aortic pressure that relate retrograde pressure pulses from foot impacts.
