Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

Diarrhea reduces the rates of cardiac protein synthesis in myofibrillar protein fractions in rats in vivo

, 2001
Although chronic diarrhea affects heart function and morphology, the pathogenic mechanisms are unknown. It was our hypothesis that diarrhea imposes metabolic stress to inhibit the synthesis of new contractile proteins.

Myofibrillar myopathy: A case report

, 2018
Myofibrillar myopathies (MFMs) are a genetically or clinically heterogeneous group of diseases that are characterized by focal myofibrillar dissolution associated with accumulation of myofibrillar degradation products and ectopic expression of multiple ...

The efficacy and physiological bases of small muscle mass exercise in health and disease

Experimental Physiology, EarlyView.
Abstract The conventional approach to aerobic exercise prescription involves large muscle mass exercise and the manipulation of variables such as training intensity, duration and frequency to promote desired adaptations. However, during whole‐body exercise, central limitations (i.e., neural, pulmonary and/or cardiac) constrain exercise tolerance and ...

Thermal gelation of brown trout crude myofibrils and myofibrillar proteins from white and red muscles

, 2001
International audienceHeat-induced gelation properties of brown trout crude myofibrils and of myofibrillar proteins (salt soluble) from white and red muscles were analysed by thermal scanning rheometry. Rheological characteristics of myofibrillar protein

Effects of chemical myosin II cross‐bridge inhibitors on eccentric force production in skinned muscle fibres

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.
