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

The 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.

The 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).

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

The 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.

Mechanisms of haemoglobin mass expansion following heat stress

The 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${

Erythropoiesis in health and disease: Distinguishing defective and ineffective erythropoiesis

Erythropoiesis is a finely regulated process ensuring continuous red blood cell production to maintain oxygen delivery. Disruptions in this process give rise to defective erythropoiesis, characterized by impaired lineage commitment and progenitor ...

Endocrine and androgenic response to altitude training in professional cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

Functional Characterization of Erythropoiesis in Fyn-/- mice: a Novel Role of Fyn in Stress Erythropoiesis

, 2018
Erythropoiesis is a dynamic complex multistep process going from committed erythroid progenitors to erythroid precursors and circulating mature red cells. Erythroid maturation is strictly dependent on EPO signaling cascade. EPO physically interacts with its receptor (EPO-R), which expression is downregulated after the basophilic erythroblasts stage.7 ...
