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 ...

Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.

Herbs in exercise and sports

open access: yesJournal of Physiological Anthropology, 2012
The use of herbs as ergogenic aids in exercise and sport is not novel. Ginseng, caffeine, ma huang (also called 'Chinese ephedra'), ephedrine and a combination of both caffeine and ephedrine are the most popular herbs used in exercise and sports.

Mechanisms of haemoglobin mass expansion following heat stress

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${

Spirulina Ameliorates Oxidative Damage and Inflammation in Rotenone-Induced Neurotoxicity in Male Mice

open access: yesInternational Journal of Medical Toxicology and Forensic Medicine, 2022
Background: Rotenone, a chemical compound produced naturally by leguminous plants, has conventionally been used as a pesticide by blocking the uptake of oxygen by body cells.

Augmenting erythropoiesis using recombinant human erythropoietin at sea level blunts the high altitude induced increase in erythropoiesis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Pharmacologically augmenting erythropoiesis with rEPO at sea level blunts the high altitude induced erythropoiesis. Abstract Erythropoiesis increases with high altitude (HA) acclimatization. Recombinant human erythropoietin (rEPO) induces erythropoiesis.

Glucose and fructose contributions to exogenous carbohydrate oxidation and performance at moderate altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Co‐ingesting fructose with glucose increases exogenous carbohydrate oxidation at sea level, but its effect at altitude is unclear. This study compared glucose–fructose (GLU–FRU), glucose alone (GLU) and placebo during 120 min of running at 70% V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$ at 2500 m in eight males.

Impact of Sprint Duration With Fixed Recovery on Acute Physiological and Performance Responses to Repeated Cycle Sprints in Hypoxia in Male and Female Sprinters

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 10, October 2026.
ABSTRACT Repeated short sprints (≤ 10 s) in hypoxia are often used to enhance performance, but acute responses to longer sprints (> 10 s) performed in a repeated‐sprint format with short recovery periods (∼30 s) remain unclear. We examined performance and physiological strain during repeated short (10‐s) and long (15‐s) sprints with identical recovery (
