Impact of heat exposure during immobilization‐induced de‐training and re‐training on aerobic capacity and haemoglobin mass

Experimental Physiology, EarlyView.
Abstract The aim of this work was to assess the effect of heat exposure on cardiorespiratory and haematological responses during de‐training and re‐training. Nineteen men (33.8 ± 2.7 years; 182 ± 5.7 cm, 84.4 ± 9.3 kg) completed 4 weeks of pre‐training followed by heat exposure (HEAT; n = 9) or control (CON; n = 10).

Haematological adaptations to high‐altitude and heat acclimation training in elite male cyclists

Experimental Physiology, EarlyView.
Abstract High‐altitude training is widely adopted by endurance athletes with the aim of increasing total haemoglobin mass (tHbmass) and thereby endurance exercise performance. However, divergent effects on tHbmass and exercise performance have been reported in athletes commencing altitude camps with initial high baseline levels for tHbmass, questioning

High altitude adaptation, common high-altitude disorders and the effects of high altitude on mental health A narrative review

Sports Psychiatry
: Introduction: The human brain is a highly oxygen-dependent organ. Low environmental oxygen availability (e.g., hypobaric hypoxia at altitude) is a major challenge to the brain and numerous endogenous cellular and systemic hypoxia responses therefore ...

Effect of live‐high, train‐low strategy induced by chronic low‐dose carbon monoxide exposure on haematological parameters and performance in trained individuals

Experimental Physiology, EarlyView.
Abstract Altitude training enhances haematological adaptations and endurance at sea level, typically requiring exposure to ∼2500 m altitude for 3–4 weeks. Emerging evidence suggests that low‐dose carbon monoxide (CO) inhalation might mimic hypoxia and might be used by elite athletes.

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

Experimental 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?

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 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 ...

A high altitude respiration and SpO2 dataset for assessing the human response to hypoxia

Scientific Data
This report presents the Harespod dataset, an open dataset for high altitude hypoxia research, which includes respiration and SpO2 data. The dataset was collected from 15 college students aged 23–31 in a hypobaric oxygen chamber, during simulated ...
