Long‐term passive heat acclimation enhances maximal oxygen consumption via haematological and cardiac adaptation in endurance runners

open access: yesThe Journal of Physiology, EarlyView.
Abstract Figure Legend Endurance‐trained runners completed a 5‐week hot‐water‐immersion (HWI) intervention (≥40°C, 45 min, five sessions per week) and a training‐matched control period in a cross‐over design. HWI induced a 33 g increase in haemoglobin mass (Hbmass) and a 10 mL expansion in left‐ventricular end‐diastolic volume (LVEDV), resulting in a 2.

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

Downregulation of EPAS1 and EGLN1 mRNA Expression Associated With High‐Altitude Adaptive Genetic Variants in Sherpa Highlanders

open access: yesAnnals of Human Genetics, Volume 90, Issue 3, Page 202-214, May 2026.
ABSTRACT Background and Aims Sherpa highlanders exhibit remarkable tolerance to hypoxia, most likely due to genetic adaptations shaped by natural selection at high altitude. This study examined the roles of endothelial PAS domain protein 1 (EPAS1) and egl‐9 family hypoxia‐inducible factor 1 (EGLN1) in the genetic mechanisms underlying this adaptation ...

Dynamic regulation of erythropoiesis: A computer model of general applicability [PDF]

open access: yes
A mathematical model for the control of erythropoiesis was developed based on the balance between oxygen supply and demand at a renal oxygen detector which controls erythropoietin release and red cell production.

Effect of Red Blood Cell Transfusion on Inflammatory and Angiogenic Pathways in Patients With Sickle Cell Disease

open access: yesAmerican Journal of Hematology, Volume 101, Issue 4, Page 718-727, April 2026.
ABSTRACT Sickle cell disease (SCD) is a chronic inflammatory state, characterized by increased plasma values of inflammatory and angiogenic proteins. Although red blood cell (RBC) transfusion is known to have immunomodulatory effects in other conditions, its potential effects on the inflammatory state in SCD remain largely unknown.

Annual Banned‐Substance Review 18th Edition—Analytical Approaches in Human Sports Drug Testing 2024/2025

open access: yesDrug Testing and Analysis, Volume 18, Issue 4, Page 458-482, April 2026.
New insights into drug metabolism, distribution, elimination, and detection assays for drugs and methods of sports doping published between 2024 and 2025 are critically reviewed and evaluated in context with the Prohibited List 2025 as established by the World Anti‐Doping Agency.

Evaluating Transcriptomic Biomarkers for rHuEPO Detection: Assessing the Impact of Exercise and Altitude Exposure

open access: yesDrug Testing and Analysis, Volume 18, Issue 4, Page 581-602, April 2026.
A two‐stage transcriptomic filter comparing rHuEPO, exercise and altitude responses reduced 153 candidate genes to 50 that were unaffected by physiological stimuli. These retained transcripts offer focused biomarker leads to strengthen antidoping detection of rHuEPO.
