Pre‐season friendly match‐play as a double‐edged sword: Performance gains and inflammatory cost in semi‐professional soccer players (a natural experiment)

open access: yesExperimental Physiology, EarlyView.
Abstract Pre‐season training prepares soccer players for competition, but the longitudinal effects of friendly match exposure remain unclear. We investigated whether cumulative late pre‐season match‐play is associated with physiological adaptation in semi‐professional players.

The contributions of nocturnal hypoxaemia and sleep disturbances to acute mountain sickness

open access: yesExperimental Physiology, EarlyView.
Abstract Acute mountain sickness (AMS) is common after ascent to altitude, yet individual susceptibility remains difficult to predict and diagnosis relies on subjective report. Sleep disturbances and nocturnal hypoxaemia at altitude may provide insight, but their relationship to AMS is incompletely understood.

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 ...

Determinants of maximal oxygen uptake in highly trained females and males: a mechanistic study of sex differences using advanced invasive methods

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...
