Excitatory drive to the α-motoneuron pool during a fatiguing submaximal contraction in man

Abstract

1. This study was undertaken to examine changes of excitatory drive to the triceps surae alpha-motoneuron pool during fatiguing submaximal isometric contractions in man. Eight healthy subjects maintained isometric plantar flexions at 30% of maximum voluntary contraction (MVC) until the limit of endurance (range, 6-9 min)
