Sex differences in cerebral pulsatility and damping: A 4D flow MRI study

open access: yesExperimental Physiology, EarlyView.
Abstract Cerebral pulsatility is a potential marker of cerebrovascular health, yet little is understood about sex differences in cerebral pulsatility with age, especially within different cerebral arteries. Additionally, cerebral damping can blunt cerebral pulsatility and might decline with age.

Temporal summation in human peripheral axons when stimulated transcutaneously with a 10‐kHz waveform

open access: yesExperimental Physiology, EarlyView.
Abstract Transcutaneous spinal cord stimulation, as used for rehabilitation of impaired motor function after spinal cord injury, often involves a 10‐kHz waveform modulated to produce repetitive bursts of stimulation. Kilohertz‐frequency waveforms may facilitate the summation of subthreshold depolarisations, but the optimal burst duration for nerve ...

Effects of 12 weeks of upper‐body rowing exercise on autonomic cardiovascular control and vascular structure in spinal cord‐injured humans

open access: yesExperimental Physiology, EarlyView.
Abstract Spinal cord injury (SCI) is characterized by autonomic cardiovascular dysfunction that may contribute to the three‐ to fourfold greater risk of heart disease and stroke compared to non‐injured individuals. While exercise training elicits beneficial changes in autonomic function and vascular structure in healthy individuals, it is unclear if ...

Heat to hypoxia cross‐adaptation: Effects of 6‐week post‐exercise hot‐water immersion on exercise performance in acute hypoxia

open access: yesExperimental Physiology, EarlyView.
Abstract Cross‐adaptation occurs when exposure to one environmental stressor (e.g., heat) induces protective responses to another (e.g., hypoxia). Although post‐exercise hot‐water immersion (HWI) induces heat acclimation, its potential to elicit cross‐adaptation remains unclear.

Blood flow restriction exercise during microgravity exposure in parabolic flight

open access: yesExperimental Physiology, EarlyView.
Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

Cerebral haemodynamic responses to inspiratory muscle work

open access: yesExperimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Use of transcutaneous spinal cord stimulation to explore inhibitory and facilitatory circuits in muscles of the human lower limb

open access: yesExperimental Physiology, EarlyView.
Abstract The aim of this study was to explore the primary afferent depolarization mechanism, to determine whether the soleus transspinal evoked potential (TEP), elicited through transcutaneous spinal cord stimulation over the L1–L2 level, is modulated by presynaptic inhibition and heteronymous facilitation, similar to the Hoffmann (H) reflex, elicited ...
