The central drive to the muscle reduces when muscle force wanes during sustained MVC, and this is generally considered the neurophysiological footprint of central fatigue. (nature.com)
Our data suggest that force and central drive to the muscle are not determinants of fatigue induced by short-lasting un-resisted repetitive finger movements, even in the presence of increased inhibition of the motor cortex. (nature.com)
The twitch-interpolation technique evaluates central fatigue by assessing the level of central drive to the muscle (also called voluntary activation, VA). It involves a first percutaneous electric stimulation (PNS) of a nerve (or muscle motor point) during a maximal voluntary contraction (MVC), which normally increases the ongoing force-torque developed by the muscle (interpolated twitch). (nature.com)

Activation order of motor axons in electrically evoked contractions. (colorado.edu)
Intermittent hypoxia-induced pLTF is associated with greater ERK phosphorylation (activation) in the region of the phrenic motor nucleus ( Wilkerson and Mitchell, 2009 ), and pLTF requires ERK (not Akt) activation in its underlying mechanism (M. S. Hoffman and G. S. Mitchell, unpublished observation). (jneurosci.org)

Plasticity is a hallmark of the respiratory control system, including plasticity in spinal respiratory motor nuclei ( Mitchell and Johnson, 2003 ). (jneurosci.org)
Here, we use phrenic motor facilitation (pMF) as a general term, including pLTF after acute intermittent hypoxia and other forms induced, for example, by spinal administration of receptor agonists. (jneurosci.org)

Because another growth/trophic factor that signals via a receptor tyrosine kinase (brain derived neurotrophic factor) elicits a long-lasting facilitation of respiratory motor activity in the phrenic nerve, we tested the hypothesis that VEGFA-165 elicits similar phrenic motor facilitation (pMF).
