How do physiological networks respond to normobaric hypoxia and isometric exercise?

Experimental Physiology, EarlyView.
Abstract The dynamics of physiological systems are impacted by both exercise and hypoxia. Network models can be used to map the interactions between various physiological components in environmental physiology and exercise using the concepts of information theory.

A new method for non‐invasive determination of effective pulmonary blood flow and cardiac output in spontaneously breathing subjects

Experimental Physiology, EarlyView.
Abstract The differential Fick method is well established for measuring effective pulmonary blood flow (EPBF) and cardiac output (CO) but until now it has only been used for patients on mechanical ventilation. Here we present and evaluate a new approach adapted to spontaneous breathing situations.

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 ...

Impaired nitric oxide‐dependent endothelial function in young male individuals with obesity before the onset of symptoms and complications

Experimental Physiology, EarlyView.
Abstract Endothelial dysfunction drives obesity‐related complications. Doppler ultrasound measurement of blood flow during 1‐min passive leg movements (PLM) is a valuable non‐invasive tool for assessing endothelial function and nitric oxide (NO)‐mediated vasodilation.

Sex and performance‐level differences in aerobic and haematological parameters among elite ski mountaineering athletes

Experimental Physiology, EarlyView.
Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...
