We assessed the effect of knee joint angle on the EMG amplitude and frequency of the four
individual muscles in the quadriceps femoris during repetitive fatiguing maximum voluntary …

The objective of the present study was to examine the superficial quadriceps femoris (QF)
muscle electromyogram (EMG) during dynamic sub-maximal knee extension exercise …

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

The objective of this study was to examine the superficial quadriceps femoris (QF) muscle
electromyogram (EMG) during fatiguing knee extensions. Thirty young adults were …

This study tested the hypothesis that fatigue of a single member of musculus quadriceps
femoris (QF) would alter use of the other three muscles during knee extension exercise …

The purpose of this study was to evaluate gender and muscle differences in
electromyographic (EMG) amplitude and median frequency mean and standard deviation …

The purpose of this study was to assess neuromuscular activation of the three superficial
portions of the quadriceps femoris muscles during linearly increasing isometric contraction …

Objectives and Methods: Isometric, fatiguing knee-extensions at 30%, 50% and 70%
maximum voluntary contraction (MVC) were performed by 18 healthy human subjects …
