The purpose of this study was to compare the neuromuscular activation patterns of the
individual muscles of the quadriceps femoris (QF), including the vastus intermedius (VI) …

The purpose of this study was to examine the effect of voluntary contraction efforts on the
median frequency (f med) of the electromyogram (EMG) recorded from the quadriceps …

We compared vasti muscle electromyograms for two knee joint angles during fatiguing
tetanic contractions. Tetanic contraction of the knee extensors was evoked for 70 s by …

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 …

PURPOSE: This study attempted to assess if the resisted contraction of medial rotators of the
tibia increases the ratio between the activity of vastus medialis (VM) and vastus lateralis (VL) …

The aim of this study was to examine superficial quadriceps femoris (QF) EMG and torque at
perceived voluntary contraction efforts. Thirty subjects (15 males, 15 females) performed 9, 5 …

Background and Purpose: The purpose of this study was to determine the difference in the
muscle activities of the Vastus Medialis Oblique (VMO), Vastus Medialis Longus (VML) …

This study determined the effects of a short period of knee isometric training on the
quadriceps muscles accessible to surface electromyography (EMG). For this purpose, a …

The purpose of this study was to determine test–retest reliability for median frequency (MDF)
and amplitude of surface EMG during sustained fatiguing contractions of the quadriceps …
