Diminished dynamic cerebral autoregulatory capacity with forced oscillations in mean arterial pressure with elevated cardiorespiratory fitness

L Labrecque, K Rahimaly, S Imhoff… - Physiological …, 2017 - Wiley Online Library
The effect that cardiorespiratory fitness has on the dynamic cerebral autoregulatory capacity
during changes in mean arterial pressure ( MAP ) remains equivocal. Using a multiple‐…

Comparable blood velocity changes in middle and posterior cerebral arteries during and following acute high‐intensity exercise in young fit women

L Labrecque, A Drapeau, K Rahimaly… - Physiological …, 2020 - Wiley Online Library
The cerebral blood flow response to high‐intensity interval training (HIIT) remains unclear.
HIIT induces surges in mean arterial pressure (MAP), which could be transmitted to the brain, …

Dynamic cerebral autoregulation and cerebrovascular carbon dioxide reactivity in middle and posterior cerebral arteries in young endurance-trained women

L Labrecque, A Drapeau, K Rahimaly… - Journal of Applied …, 2021 - journals.physiology.org
The integrated responses regulating cerebral blood flow are understudied in women,
particularly in relation to potential regional differences. In this study, we compared dynamic …

Impact of sex on the cerebrovascular response to incremental aerobic exercise in moderately trained endurance athletes

…, MA Roy, F Billaut, K Rahimaly… - Journal of Applied …, 2023 - journals.physiology.org
The cerebrovascular response to incremental aerobic exercise is comparable between males
and females. Whether this response can be found in moderately trained athletes remains …

Multi-metrics assessment of dynamic cerebral autoregulation in middle and posterior cerebral arteries in young fit women

L Labrecque, A Drapeau, K Rahimaly, S Imhoff… - bioRxiv, 2020 - biorxiv.org
Individuals with low orthostatic tolerance show greater decrease in posterior cerebral artery
mean blood velocity (PCAv mean ). Since young fit women often experience presyncopal …

Elevated Cardiorespiratory Fitness is Associated with Blunted Cerebral Pressure‐Flow Relationships

…, O Le Blanc, S Malenfant, K Rahimaly… - The FASEB …, 2017 - Wiley Online Library
There appears to be a “hemodynamic paradox” associated with elevated cardiorespiratory
fitness; in that it has a differential impact on cerebral blood flow and orthostatic tolerance. A …
