Eleven subjects performed isometric knee extensor contractions at maximum voluntary
contraction (MVC), and at 70% of MVC preceding and following a fatigue test. The fatigue …

The purpose of this study was to investigate the behavior of electromyographical (EMG) and
vibromyographical (VMG) signals in the time and frequency domains during a fatigue …

The proposal of this study was to analyze the behavior of electromyographic activity of the
Rectus Femoris, Vastus Lateralis and Vastus Medialis muscles during Maximum Isometric …

The purpose of this study was to compare the power outputs associated with the onset of
neuromuscular fatigue in the superficial muscles of the quadriceps femoris group by …

The purpose of this study was to investigate neuromuscular activation of the vastus
intermedius (VI) muscle during fatiguing contraction. Seven healthy men performed …

Isometric knee extensions until exhaustion at 30%, 50%, and 70% of maximum voluntary
contraction were performed by 18 healthy subjects. During muscle fatigue, surface …

The objective of this study was to analyze the electromyographic (EMG) signal behavior of
rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL) and biceps femoris (caput …

The present study aimed to investigate the shift in the mean frequency (fmean) of the power
density spectrum of the electromyogram (EMG) during endurance tests of the knee …
