In vitro muscle contraction: A technical review on electrical pulse stimulation in C2C12 cells

Experimental Physiology, EarlyView.
Abstract Electrical pulse stimulation (EPS) of skeletal muscle cells is increasingly used to model exercise In vitro. The murine C2C12 myotube system has become a common platform for such studies, yet wide variability in EPS protocols hampers reproducibility and cross‐study comparisons.

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 ...

Exercise during 14 days of head down tilt bedrest attenuates motor unit impairments in older humans

Experimental Physiology, EarlyView.
Abstract Head‐down tilt bedrest (HDBR) models the effects of mechanical unloading on neuromuscular function. The efficacy of exercise in preserving motor unit (MU) function in older adults during HDBR remains unclear. This study investigated the effects of 14‐day HDBR on MU properties in older adults and the protective role of exercise.

Cells and ionic conductances contributing to spontaneous activity in bladder and urethral smooth muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Cells and conductances contributing to spontaneous activity in the lower urinary tract. Bladder and urethra exhibit spontaneous contractions at both cellular and tissue levels. Both detrusor and urethral smooth muscle cells display activity that is regular and rhythmic.
