The orientation of the resultant force during a given contraction depends on the architecture
of the muscles involved, and cooperation among muscles may induce force fluctuations in …

Net muscle force recorded during voluntary contractions with multiple agonist muscles is the
summated result of individual muscle forces. The purpose of this article is to synthesize …

During isometric contractions, the fluctuation of the force output of muscles increases as the
muscle fatigues, and the contraction is sustained to exhaustion. We analyzed motor unit …

The purpose of this study was to investigate the asymmetry of force fluctuation in the leg
muscles during isometric knee extension and flexion. Twenty healthy males (21±2 years) …

The study was conducted to contrast exertion-dependent changes in electromyography
(EMG), force fluctuation (FF), and limb acceleration (LA) during isometric contraction to attain …

Alternate muscle activity between synergist muscles has been demonstrated during low-
level sustained contractions [≤ 5% of maximal voluntary contraction (MVC) force]. To …

The aim of this study was to investigate the effects of agonist and antagonist muscle fatigue
on the performance of rapid, self-terminating movements. Six subjects performed rapid …

Mechanomyography (MMG) provides a measure of muscle mechanical changes during
contractions. The purpose of this study was to quantify alterations in MMG signals during …

The purpose of this study was to evaluate whether agonist muscle fatigue changed the
coactivation time and the co-contraction magnitude of the agonist and antagonist muscle …

The aim of this study was to quantify the effects of spatial reorganisation of muscle activity on
task-related and tangential components of force variability during sustained contractions …
