Alteration in sympathoadrenergic activity at rest and during intense exercise despite normal aerobic fitness in late pubertal adolescent girls with type 1 diabetes

An impaired sympathoadrenergic response to hypoglycaemic episodes has been described in young Type 1 diabetic subjects. It is unknown if this altered response occurs with exercise, and if it could influence aerobic power.Body composition (skinfold thickness), physical activity (questionnaire) and aerobic power (PWC170 and VO2max) were assessed in 19 post-menarcheal Type 1 diabetic (T1D) girls (13.3-18.2 years) and 19 healthy siblings. At rest...
