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.

Intermittent low‐intensity contractions cause a dissociation between maximal motor unit firing rates and changes in torque and contractile speed

Experimental Physiology, EarlyView.
Abstract The purpose was to test: (1) whether the decline in maximal motor unit (MU) firing rate is an invariable response when maximal voluntary contraction (MVC) torque is reduced following a submaximal muscle fatiguing task; and (2) whether fatigue‐induced slowing of contractile speed and firing rate decline are co‐dependent. Ten participants (three

Somatosensory processing in long COVID fatigue and its relations with physiological and psychological factors

Experimental Physiology, EarlyView.
Abstract We aimed to quantify somatosensory processing in long COVID and interactions between somatosensory processing, fatigability, fatigue, autonomic function, mood and illness beliefs. Eighty‐eight participants (44 long COVID and 44 controls) were invited to complete two testing sessions, where fatigue was induced by either a cognitive or a ...

A comparison of the neuromuscular, cardiopulmonary and muscle oxygenation responses to single‐ and double‐leg cycling in older adults

Experimental Physiology, EarlyView.
Abstract Previous work in younger adults has shown that during small muscle mass exercise, the tolerable degree of neuromuscular impairment at task failure is greater than during large muscle mass exercise. However, no study has compared the neuromuscular responses to small and large muscle mass exercise whilst matching exercise modality in older ...
