The purpose of this study was to investigate the effects of 12-week aerobic exercise training on cardiac QT intervals and cardiovascular risk profiles in type 1 diabetic children. Eleven type 1 diabetic children aged 9-17 years took part in this study as subject. The participants performed aerobic exercise training three times a week for total 12 weeks. The intensity of the training was adjusted at HRR 45% until three weeks and at HRR 55% since four weeks. After a 12-week aerobic exercise training systolic (p<0.05) and diastolic (p<0.05) blood pressure of the subjects was decreased. There was significant decrease in cardiac QT intervals (p<0.05), TC level (p<0.05), and HDL-C level (p<0.05). Therefore, the results of this study suggest that long-term regular physical activity of type 1 diabetic children considered exercise intensity and frequency may effect and play a important role in the prevention of diabetic complications and cardiovascular health care.
