Eighteen adolescents with various forms of cerebral palsy performed tests on a mechanically braked ergometer bicycle. VO2 was measured at different loads and net mechanical efficiency calculated. It was found that efficiency was poor at light loads for most of the students but that there were significant intergroup differences in mechanical efficiency at higher loads. The leveling-off plateau demonstrated by healthy adolescents was only attained by a few of the disabled students. It was concluded that the muscle hypertonia and involuntary movements were responsible for the high level of energy expended in the mechanical work performed.
