Physiol. 35(5): 739-740. 1973.A bicycle ergometer suitable for both positive and negative work studies has been described. The motor driving the ergometer provides constant velocities of pedal revolution ranging from 10 to 120 spm, and overcomes all mechanical forces involved in passive The increase in motor torque recorded during leg movements. active exercise provides a more accurate measure of the actual work done by the subject than can be obtained from other conventional ergometers. The subject is seated in a chair behind the ergometer which allows him to relax the nonworking muscles as completely as possible. With this ergometer the subjects’ passive, free-pedaling oxygen consumptions for both forward and reverse pedal directions are found to be close to resting values, varying little with rpm. These are compared to the progressively rising free-pedaling values obtained as pedaling speed is increased when the ergometer is used in the conventional manner. WOODS.
