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 ...

Interpreting peripheral oxygen saturation variability in critical illness: A directional framework adjusted for hypoxia severity

Experimental Physiology, EarlyView.
Abstract Peripheral oxygen saturation (SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$) exhibits a complex pattern of fluctuations during hypoxia, which can be quantified using entropy measures. SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$ entropy analysis provides insights into dynamic physiological regulation by non‐invasively reflecting the body's capacity to ...

Cardiovascular, respiratory and splenic responses to rebreathing and apnoea during exercise

Experimental Physiology, EarlyView.
Abstract We investigated integrative physiological responses to eupnoeic exercise (EX), rebreathing exercise (RB), dynamic apnoea (DA) and dynamic apnoea with cold‐water face immersion (DAFI) in 20 healthy participants. Trials involved non‐steady‐state cycle exercise at 60 W for an average duration of 66 s.

Postexercise muscle oxygen uptake kinetics in older breast cancer survivors and healthy individuals: Association with myosteatosis

Experimental Physiology, EarlyView.
Abstract Reduced cardiorespiratory fitness is common among breast cancer survivors and, although traditionally attributed to cardiac dysfunction, might also be related to peripheral skeletal muscle abnormalities. We examined peak and submaximal plantar‐flexion exercise and recovery kinetics for lower‐leg oxygen uptake (V̇O2${\dot V_{{{\mathrm{O}}_2}}}$)
