Impact of living and training at low altitude for several years on endurance performance at higher altitude: Myth or reality

open access: yesExperimental Physiology, EarlyView.
Abstract The physiological adaptations of long‐term high‐altitude residents without high‐altitude genetic ancestry remain poorly characterized. This study investigated whether permanent residence at low altitude (1200 m) influences performance at higher altitude (2500 m). We compared exercise responses at 2500 m in endurance‐trained athletes living for

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.

Intramuscular pathways of maladaptation in overtraining syndrome

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

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${
