title: Physical aptitudes to exertion in children with Down's syndrome.
abstract: The individual with Down's syndrome is characterized by apathy towards physical exercise. Ten untrained subjects with Down's syndrome and a control group have been tested at rest and after exercise on a bicycle ergometer. In subjects with Down's syndrome, the authors have observed: (a) a lower orthostatic index at rest; (b) a lower indirect maximal oxygen consumption; (c) a shorter performance time and a lower maximal workload; (d) a higher urinary catecholamines excretion; (e) a blood pressure which did not rise regularly with the workload increment. It is concluded that, in subjects with Down's syndrome, the low level of physical fitness is not only explained by lack of motivation but also by physiological impairments.
