Fig. 2From: 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 curve of pressure signal during HIMA including the isometric parts. The different parts of the pressure signal were used inter alia for the cut of the other signals. The following parts can be differentiated: the pressure increase (gray), the total isometric phase (black), single isometric phases (orange) and the longest single isometric phase (red). The serrated deviations of the line show moments of jerky yieldingBack to article page
