Intramuscular pathways of maladaptation in overtraining syndrome

The 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

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${

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

The 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 ...

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

The 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 ...

Improved subjective sleep quality in older adults by enhancing the GABAergic system in the sensorimotor cortex

The Journal of Physiology, EarlyView.
Abstract figure legend Sleep disturbances are common in older adults, highlighting the need for accessible interventions to improve sleep quality. Eighteen older adults per group (balance training and control) were assessed before and after 12 weeks. The balance group increased GABA levels (magnetic resonance spectroscopy) and functional connectivity ...
