Figure 1

High muscle forces are generated on an eccentric stepper (Eccentron; BTE Technologies, Inc., Hanover, MD, USA) powered by a 2-horsepower motor that drives the pedals. As the pedals move toward the participant (largest arrow), the rider resists by applying force to the pedals (arrow at foot level). Because the magnitude of force produced by the motor exceeds that produced by the rider, the leg extensors (arrows in thigh) work eccentrically (lengthening), creating negative work.
