Fig. 3From: Are there two forms of isometric muscle action? Results of the experimental study support a distinction between a holding and a pushing isometric muscle functionExemplary signals of MMG of the triceps muscle. Displayed are the isometric phases of offset raw MMG signals of the triceps muscle during the holding isometric muscle action (HIMA; above) and during the pushing isometric muscle action (PIMA; below) at 80% of the MVC. The zoomed areas show a one-second sequenceBack to article page
