Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse

Experimental Physiology, EarlyView.
Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

Skeletal muscle myosin heavy chain fragmentation following exercise may be linked to post‐exercise inflammation and remodelling

Experimental Physiology, EarlyView.
Abstract The purpose of this exploratory investigation was to determine if acute post‐exercise skeletal muscle myosin heavy chain fragmentation (MyHCfrag) coincides with alterations in molecular chaperones and proteolytic enzymes, select markers of mammalian target of rapamycin complex 1 (mTORC1) signalling, and/or specific gene expression signatures ...

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 ...

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

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.
