Cerebral blood flow and metabolism during exercise.
During exercise regional cerebral blood flow (rCBF), as blood velocity in major cerebral arteries and also blood flow in the internal carotid artery increase, suggesting an increase in blood flow to a large part of the brain. Such an increase in CBF is independent of the concomitant increase in blood pressure but is modified by the alteration in arterial carbon dioxide tension (PaCO(2)). Also, ...
متن کاملTitle : Cerebral blood flow during exercise ; mechanisms of regulation 1
21 The response of cerebral vasculature to exercise is different from other peripheral 22 vasculature; it has a small vascular bed, and is strongly regulated by cerebral 23 autoregulation and the partial pressure of arterial carbon dioxide (PaCO2). In contrast to 24 other organs, the traditional thinking is that total cerebral blood flow (CBF) remains 25 relatively constant and is largely unaff...

متن کاملCerebral blood flow and metabolism during exercise: implications for fatigue.
During exercise: the Kety-Schmidt-determined cerebral blood flow (CBF) does not change because the jugular vein is collapsed in the upright position. In contrast, when CBF is evaluated by (133)Xe clearance, by flow in the internal carotid artery, or by flow velocity in basal cerebral arteries, a approximately 25% increase is detected with a parallel increase in metabolism. During activation, an...
متن کاملThe effect of changes in cerebral blood flow on cognitive function during exercise
No studies have identified the direct effect of changes in cerebral blood flow (CBF) on cognitive function at rest and during exercise. In this study, we manipulated CBF using hypercapnic gas to examine whether an increase in CBF improves cognitive function during prolonged exercise. The speed and the accuracy of cognitive function were assessed using the Stroop color-word test. After the Stroo...
