Fig. 6From: Are there two forms of isometric muscle action? Results of the experimental study support a distinction between a holding and a pushing isometric muscle functionItems of the endurance measurements comparing the PIMA (blue) vs. HIMA (gray). The bars display the duration time [s] of different items of maintaining 80% of MVC comparing the pushing isometric muscle action (PIMA; blue) vs. the holding isometric muscle action (HIMA, gray). *p < .05, ** p < .01Back to article page
