Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

open access: yesExperimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Physical activity partly inhibits autonomic imbalance, immune dysfunction and quality of life induced by chronic shiftwork in policemen

open access: yesExperimental Physiology, EarlyView.
Abstract Chronic shiftwork can impair autonomic cardiovascular regulation and immune homeostasis. However, the interaction between occupational status and physical activity level in military police officers remains incompletely understood. This cross‐sectional factorial study included 102 men stratified according to occupational status and physical ...

A 45 min bout of hot‐water immersion induces transient plasma volume contraction without a detectable increase in circulating erythropoietin

open access: yesExperimental Physiology, EarlyView.
Abstract Heat acclimation is increasingly used to induce haematological adaptations and enhance endurance performance. Although repeated hot‐water immersion (HWI) has been shown to increase haemoglobin mass, the acute physiological responses that might underpin these longer‐term adaptations remain poorly understood.

Altitude or heat training to increase haemoglobin mass and endurance exercise performance in elite sport

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Upper panel, high‐altitude training typically encompasses 3–4 weeks of altitude exposure combined with training either at altitude or at sea level. Following this, a response for haemoglobin mass (Hbmass) is seen in two of three studies, which coincides with some performance gains in <50% of studies.

Angiotensin‐converting enzyme and exercise adaptations: Genetic variability, pharmacological modulation and future directions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend ACE I/D genotype, enzyme activity and integrated physiological adaptations. Upper panel: Conceptual framework linking the ACE I/D polymorphism (left) with circulating/tissue ACE activity (centre; violin plots based on hypothetical data for illustration) and strength/power versus endurance phenotypes (right).
