Fig. 1From: Are there two forms of isometric muscle action? Results of the experimental study support a distinction between a holding and a pushing isometric muscle functionSetting for measuring HIMA and PIMA with the pneumatic system. The MMG/MTG of triceps brachii muscle and its tendon as well as the MMG of the abdominal external oblique muscle are recorded with piezo-sensors. The pressure is regulated with the control unit. All signals pass the A/D-converter and are recorded with DIAdem 10.2 on the measuring laptopBack to article page
