Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

open access: yesExperimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

The impact of biological sex and stroke volume constituents on heterogeneity in the Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$ relationship and skeletal muscle saturation during cycling

open access: yesExperimental Physiology, EarlyView.
Abstract Interindividual variability in the cardiac output (Q̇$\dot{Q}$) to the rate of oxygen consumption (V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) slope (Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) in healthy males is related to stroke volume (SV); however, the impact of differences in left ventricular (LV) structure and function as well as ...

Mechanisms of haemoglobin mass expansion following heat stress

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${
