Percent duration of force for both groups and cadences. Subjects with CP spent a smaller percentage of the revolution applying positive force (pushing into the pedal) and a greater percentage of the revolution applying negative force (pulling away from the pedal) than did subjects with TD regardless of the cycling cadence (P < .001). There was no main effect of cadence (P > .05) and no interaction effect of group and cadence (P > .05). TD30 = subjects with typical development cycling at 30 rpm, TD60 – subjects with typical development cycling at 60 rpm, CP30 –subjects with cerebral palsy cycling at 30 rpm, CP60 – subjects with cerebral palsy cycling at 60 rpm.
