The Behaviour of the Cerebral Circulation during Muscular Exercise

Authors


Abstract

The behaviour of the cerebral circulation during muscular exercise has been studied in 4 healthy males by injecting labelled erythrocytes into the internal carotid arteries and sampling from the internal jugular bulbs. There seems to be little if any increase in the cerebral blood flow and the circulation time through the brain, even though there was a considerable rise in the cardiac output and the arterial blood pressure. The cerebral blood volume was apparently constant
