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.

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 ...

Semaglutide impacts skeletal muscle to a similar extent as caloric restriction in mice with diet‐induced obesity

The Journal of Physiology, EarlyView.
Abstract figure legend Four weeks of semaglutide treatment causes significant reductions in total body weight, fat mass, lean mass, and grip strength in mice with diet induced obesity. Mice treated with semaglutide lost a greater amount of total body weight and fat mass compared to mice fed fed a calorie matched diet.

Excessive training does not induce mitochondrial dysfunction or impair insulin signalling within skeletal muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Three weeks of overtraining in trained endurance athletes reduced exercise performance without impairing glucose tolerance. In skeletal muscle, overtraining was associated with increased expression of lipid metabolism‐related proteins, enhanced mitochondrial biogenesis and preserved insulin signalling, despite elevated oxidative ...

NSAID ingestion augments training‐induced muscle hypertrophy and differentially affects muscle mRNA expression, but not strength gains, in trained men

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the impact of NSAID ingestion on resistance exercise training‐induced changes in muscle morphology, function and gene networks relative to placebo ingestion in trained males. Abstract Non‐steroidal anti‐inflammatory drugs (NSAIDs) are widely overused in sports.

Resistance training load does not determine resistance training‐induced hypertrophy across upper and lower limbs in healthy young males

The Journal of Physiology, EarlyView.
Abstract figure legend In healthy young males, we found that skeletal muscle hypertrophy following a period of resistance exercise training (RET) was consistent within and between subjects, as assessed using a variety of established methods. The skeletal muscle hypertrophic response was independent of external load.

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

The 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 ...

The role of group III/IV afferent feedback in the ventilatory, pressor and metabolic responses to exercise in normoxia and hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,

Non‐steady‐state modelling reveals reduced skeletal muscle protein synthesis as the primary driver of disuse‐atrophy in young, healthy females

The Journal of Physiology, EarlyView.
Abstract figure legend We used a unilateral model of divergent contractile stimuli, in which one leg was subjected to 10 days of unloading and the contralateral leg was simultaneously subjected to loading. We examined how accounting for changes in protein pool size, using steady‐state and non‐steady‐state modelling approaches, impacted rates of muscle ...
