Regional cerebral blood flow distribution during exercise: Influence of oxygen

Highlights ► The increase in velocity of the middle cerebral artery is greater than that of posterior cerebral artery during exercise. ► Increases of velocity of middle cerebral artery blood flow was not different during normoxic and hypoxic exercises. ► Posterior cerebral artery velocity was signif...

Description
Summary:Highlights ► The increase in velocity of the middle cerebral artery is greater than that of posterior cerebral artery during exercise. ► Increases of velocity of middle cerebral artery blood flow was not different during normoxic and hypoxic exercises. ► Posterior cerebral artery velocity was significantly increased during hyperoxic exercise. ► Absolute increases in posterior cerebral velocity and middle cerebral velocity during hyperoxic exercise are similar.
