Fig. 2From: Submaximal cardiopulmonary thresholds on a robotics-assisted tilt table, a cycle and a treadmill: a comparative analysisRobotics-assisted tilt table (RATT) with visual feedback system. The visual feedback screen shows the target work rate and the subject’s work rate. The subject’s work rate was calculated from the forces in the thigh cuffs and the angular velocitiesBack to article page
