A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

open access: yesExperimental 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 ...

Maximal strength and voluntary activation of adductor pollicis after a single session of acute intermittent hypercapnia or acute intermittent hypoxia

open access: yesExperimental Physiology, EarlyView.
Abstract Acute intermittent hypoxia (AIH) can increase maximal strength of limb muscles in people with incomplete spinal cord injury (SCI), but it is mostly untested in people without SCI. Acute intermittent hypercapnia (AIC) may engage similar respiratory circuits to AIH, but the effects of AIC on human limb motor output are unknown.

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

open access: yesExperimental 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

open access: yesExperimental 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${\dot V_{{{\mathrm{O}}_2}}}$)

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).
