Cerebral blood flow and oxygenation at maximal exercise: the effect of clamping carbon dioxide

JT Olin, AC Dimmen, AW Subudhi, RC Roach - Respiratory physiology & …, 2011 - Elsevier
During exercise, as end-tidal carbon dioxide ([Formula: see text]) drops after the respiratory
compensation point (RCP), so does cerebral blood flow velocity (CBFv) and cerebral …

Regulation of cerebral blood flow during exercise

JS Querido, AW Sheel - Sports medicine, 2007 - Springer
Constant cerebral blood flow (CBF) is vital to human survival. Originally thought to receive
steady blood flow, the brain has shown to experience increases in blood flow during …

CO2 supplementation dissociates cerebral oxygenation and middle cerebral artery blood velocity during maximal cycling

RK Hansen, PS Nielsen, MW Schelske… - … journal of medicine …, 2020 - Wiley Online Library
This study evaluated whether the reduction of prefrontal cortex oxygenation (ScO2) during
maximal exercise depends on the hyperventilation‐induced hypocapnic attenuation of …

[HTML][HTML] On the limits of cerebral oxygen extraction

AR Bain, PN Ainslie - The Journal of physiology, 2014 - ncbi.nlm.nih.gov
There are over 60 peer-reviewed reports of cerebral blood flow (CBF) changes during
exercise. A recurrent finding is that CBF increases by 10–30% from rest to 60% of peak …

Cerebral blood flow and metabolism during exercise

K Ide, NH Secher - Progress in neurobiology, 2000 - Elsevier
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 …

Cerebral blood flow during exercise: mechanisms of regulation

S Ogoh, PN Ainslie - Journal of applied physiology, 2009 - journals.physiology.org
The response of cerebral vasculature to exercise is different from other peripheral
vasculature; it has a small vascular bed and is strongly regulated by cerebral autoregulation …

The Effect of Adding CO2 to Hypoxic Inspired Gas on Cerebral Blood Flow Velocity and Breathing during Incremental Exercise

JL Fan, B Kayser - PloS one, 2013 - journals.plos.org
Hypoxia increases the ventilatory response to exercise, which leads to hyperventilation-
induced hypocapnia and subsequent reduction in cerebral blood flow (CBF). We studied the …

Cerebral blood flow during submaximal and maximal dynamic exercise in humans

SN Thomas, T Schroeder… - Journal of applied …, 1989 - journals.physiology.org
Cerebral blood flow (CBF) in humans was measured at rest and during dynamic exercise on
a cycle ergometer corresponding to 56%(range 27–85) of maximal O2 uptake (VO2max) …

Does cerebral oxygen delivery limit incremental exercise performance?

AW Subudhi, JT Olin, AC Dimmen… - Journal of Applied …, 2011 - journals.physiology.org
Previous studies have suggested that a reduction in cerebral oxygen delivery may limit
motor drive, particularly in hypoxic conditions, where oxygen transport is impaired. We …

Effect of end‐tidal CO2 clamping on cerebrovascular function, oxygenation, and performance during 15‐km time trial cycling in severe normobaric hypoxia: the role of cerebral O …

JL Fan, N Bourdillon, B Kayser - Physiological reports, 2013 - Wiley Online Library
During heavy exercise, hyperventilation‐induced hypocapnia leads to cerebral
vasoconstriction, resulting in a reduction in cerebral blood flow (CBF). A reduction in CBF …
