Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

open access: yesExperimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...

Muscle oxygen saturation plateau: Definition and verification in different oxygen availability conditions in locomotor and non‐locomotor muscles

open access: yesExperimental Physiology, EarlyView.
Abstract Novel wearable near‐infrared spectroscopy devices allow for a better understanding of muscle oxygenation kinetics during exercise. A muscle oxygen saturation (SmO2) plateau is often applied in the scientific literature, but clear criteria for its definition remain unestablished to date.

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...

Early acclimatization to high altitude: Acid–base and fluid balance dynamics during the first 2 days at 3100 m

open access: yesExperimental Physiology, EarlyView.
Abstract Immediate responses to hypoxia at high altitude are hyperventilation and successive respiratory alkalosis. Alkalosis, in turn, can affect cerebrospinal fluid pH and ventilatory control. The kidneys compensate metabolically for respiratory alkalosis.

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

open access: yesExperimental 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.
