Fig. 2From: Robot-assisted assessment of muscle strengthSchematic 5-min all-out test to determine critical force or critical moment. Dots represent 60 maximal intended isometric muscle actions for a given motor task with a 60% duty cycle (3 s force exertion, 2 s rest). The achieved end-test force or end-test moment corresponds to the critical force and critical moment, respectively, which are indicative of an individual’s neuromuscular fatigue thresholdBack to article page
