Timeline of adjustments in cycling speed and resistance level over the course of two experiments in an exemplary subject: one with high resistance (top) and one with low resistance (bottom). The left-hand portions of the plots show the initial warm-up and ramp-up phases. The Borg rating of perceived exertion (RPE), in purple, shows the value reported by the subject during the sustained pedaling phase after ramp-up
