Introduction. The purpose of this study was to examine neuromuscular activation and ratings
of perceived exertion (RPE) at 10% and 80% quadriceps MVC in healthy males. Methods …

Contracting the knee flexor muscles immediately before a maximum voluntary contraction
(MVC) of knee extension increases the maximal force that the extensor muscles can exert. It …

Eighteen adults performed isometric muscle actions of the leg extensors at 25, 50, 75, and
100% maximal voluntary contraction (% MVC) at leg flexion angles of 25, 50, and 75°. The …

The purpose of this study was to examine the differences in electromyographic activity of
agonist and antagonist knee musculature between a maximal and a submaximal isokinetic …

The purpose of this study was to examine coactivation patterns of the lateral and medial
quadriceps and the lateral and medial hamstrings during low-and moderate-speed …

Electromyographic (EMG) activity was recorded from the five components of the quadriceps
during maximum knee extension with the limb in six combinations of hip and knee flexion …

Neuromuscular electrical stimulation (NMES) has been used to increase muscle strength
and physical function. However, NMES induces rapid fatigue, limiting its application. To …

We aimed to test the hypothesis that the magnitude of differences in muscle activation of the
knee and hip extensor muscles between high-intensity interval exercise (HIE) and moderate …

Introduction To compare the power spectral changes of the voluntary surface
electromyogram (sEMG) and of the compound action potential (M wave) in the vastus …

The clinical application of EMG requires that the recorded signal is representative of the
muscle of interest and is not contaminated with signals from adjacent muscles. Some …
