Effects of a Physical Activity Program on Metabolic Control and Cardiovascular Fitness in Children with Insulin-dependent Diabetes Mellitus

The purpose of this investigation was to determine the effects of a regular vigorous physical activity program on children aged 5–11 yr with insulin-dependent diabetes mellitus (IDDM). The experimental group of children (N = 9) took part in a 30-min vigorous exercise program three times a week for 12 wk; the control group (N = 10) did not. Hemoglobin A₁ (HbA₁) and fasting blood glucose (FBG) were used to determine metabolic control. Oxygen consumption was evaluated by treadmill testing and analyses of expired air. The experimental group significantly (P < 0.05) decreased their HbA₁ and FBG while the control group showed no change. The experimental group significantly (P < 0.05) increased their peak aerobic capacity (ml/kg min) when compared with baseline values (47.14 ± 1.94 versus 50.69 ± 1.30). It was concluded that a carefully applied program of regular vigorous physical activity can beneficially influence metabolic control and cardiovascular fitness in young children with IDDM.
