Brain function critically depends on a close matching between metabolic demands,
appropriate delivery of oxygen and nutrients, and removal of cellular waste. This matching …

The effects of physical activity on cerebral blood flow (CBF) and cerebral autoregulation
(CA) have not yet been fully evaluated. There is controversy as to whether increasing heart …

Non‐technical summary Exercise capacity is limited at high altitude where hypoxia (ie
decreased amount of inspired oxygen resulting in decreased oxygen in the blood) is …

We examined the relationship between changes in cardiac output and middle cerebral
artery mean blood velocity (MCA Vmean) in seven healthy volunteer men at rest and during …

Although cerebral autoregulation (CA) appears well maintained during mild to moderate
intensity dynamic exercise in young subjects, it is presently unclear how aging influences …

Blood flow in the cerebral circulation, as in other regional circulations, is regulated by four
primary factors; metabolic stimuli, perfusion pressure, chemical stimuli, and autonomic …

We tested the hypothesis that pharmacological reduction of the increase in cardiac output
during dynamic exercise with a large muscle mass would influence the cerebral blood …

In 1923, Nobel Laureate AV Hill proposed that maximal exercise performance is limited by
the development of anaerobiosis in the exercising skeletal muscles. Variants of this theory …

A substantial number of people who sustain a mild traumatic brain injury report persistent
symptoms. Most common among these symptoms are headache, dizziness, and cognitive …

Cerebral autoregulation is the ability of the cerebral vasculature to maintain stable blood
flow despite changes in blood pressure (or, more accurately, cerebral perfusion pressure) …
