Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Corticospinal, reticulospinal and motoneuronal contributions to fatigability during a sustained contraction of the elbow flexors

Experimental Physiology, EarlyView.
Abstract Synaptic input to the motoneuron pool is altered during fatiguing muscle contractions. In humans, the corticospinal tract is often studied, with equivocal findings regarding its role in the reduction of force. To date, the involvement of the reticulospinal tract during states of fatigue has not been explored.

Changes in corticospinal excitability in response to mediolateral gait instability

Experimental Physiology, EarlyView.
Abstract Unpredictable gait disturbances, particularly in the mediolateral direction, pose a significant challenge to stability and are a common contributor to falls. Although the corticospinal tract is critical for gait and postural control, its response to such instabilities remains unclear.

Maximal strength and voluntary activation of adductor pollicis after a single session of acute intermittent hypercapnia or acute intermittent hypoxia

Experimental Physiology, EarlyView.
Abstract Acute intermittent hypoxia (AIH) can increase maximal strength of limb muscles in people with incomplete spinal cord injury (SCI), but it is mostly untested in people without SCI. Acute intermittent hypercapnia (AIC) may engage similar respiratory circuits to AIH, but the effects of AIC on human limb motor output are unknown.

Effects of a high‐sugar mixed meal on cerebrovascular haemodynamics in young, healthy versus middle‐aged adults with cardiometabolic risk factors

Experimental Physiology, EarlyView.
Abstract Consumption of a high‐sugar mixed meal (HSMM) increases both glucose and insulin and elicits mixed vascular effects, with reduced microvascular blood flow but increased conduit artery diameter and blood flow. In this study, we sought to examine: (1) whether an HSMM elicits vascular segment‐specific effects within cerebrovasculature; and (2 ...
