Experimental Physiology, EarlyView.Abstract Mechanical ventilation (MV) is a life‐saving intervention applied to critically ill patients. A common consequence of MV is ventilator‐induced diaphragm dysfunction (VIDD), which is characterized by significant diaphragm atrophy and reduced contractile function. Older patients who receive MV are more likely to develop VIDD, have worse recovery,

Myosin folding boosts solubility in cardiac muscle sarcomeres. [PDF]
The polymerization of myosin molecules into thick filaments in muscle sarcomeres is essential for cardiac contractility, with the attenuation of interactions between the heads of myosin molecules within the filaments being proposed to result in ...

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 ...

Experimental Physiology, EarlyView.Abstract Eccentric muscle contractions are essential for locomotion and daily activities. Force during these contractions depends on both cross‐bridge (XB) and non‐cross‐bridge (non‐XB) elements, including titin, with contributions varying by fibre type and contraction velocity.

The Journal of Physiology, EarlyView.Abstract figure legend Using a multiscale computational model of left ventricular electromechanics, we investigated how sarcomere dynamics influence the end‐systolic pressure‐volume (ESPV) relationship in ejecting beats compared to isovolumetric beats.

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 ...
