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

To determine quantitatively the features of alternate muscle activity between knee extensor
synergists during low-level prolonged contraction, a surface electromyogram (EMG) was …

The study examined the hypothesis that altered synergistic activation of the knee extensors
leads to cyclic modulation of the force fluctuations. To test this hypothesis, the force …

Introduction: We quantified the alternate muscle activity among four synergists of the
quadriceps femoris (QF), including the vastus intermedius (VI), during low‐level sustained …

Nonlocal muscle fatigue occurs when fatiguing 1 muscle alters performance of another
rested muscle. The purpose of the study was to investigate if fatiguing 2 separate muscles …

Coactivation is antagonist muscle activity that occurs during voluntary contraction. Recently,
we showed that the extent of coactivity in the knee flexors decreases after a short period of …

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 …

The purpose of this study was to investigate the functional interrelationship between
synergistic muscle activities during low-level fatiguing contractions. Six human subjects …

Purpose The aim of this study was to examine control strategies among synergistic muscles
after fatigue of a single muscle. It was hypothesized that the compensating mechanism is …

1 In keeping with the 'muscular wisdom hypothesis', many studies have documented that the
firing rate of the majority of motor units decreased during fatiguing isometric contractions …
