title: Cardiovascular, hormonal and metabolic responses to graded exercise in juvenile diabetics with and without autonomic neuropathy.
abstract: Thirteen juvenile diabetics were studied in order to determine if decreased beat-to-beat variation during deep respiration, indicating abnormal autonomic nerve function, imply that cardiovascular, hormonal and metabolic responses are impaired. Patients with decreased beat-to-beat variation had to be more heavily stressed during exercise to reach a certain heart rate or catecholamine level. The relation between other metabolic and hormonal response is discussed.
