Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

A cascade model of dynamic cerebral autoregulation

The Journal of Physiology, EarlyView.
Abstract figure legend This study examined a two‐component cascade model linking upstream dynamic cerebral autoregulation (dCA) with downstream microvascular function (MF) to explain how blood pressure oscillations influence cortical oxygenation. Transfer function analysis in the frequency domain was applied to quantify H1(f) (MAP→CBFV; dCA), H2(f ...
