This study evaluated the effect of aerobic versus resistance training on metabolic control in type-1 diabetes patients. Thirteen non-active patients, ranging in age from 13-30, were submitted to a 12-week aerobic exercise (Group A, n = 7) or resistance training (Group B, n = 6) period. Group A training consisted of a 40 min walk or run and Group B training consisted of resistance exercises three times a week. Blood samples were obtained before and after the 12-week training period. When these samples were compared, results showed that in Group A there were no changes in glycated hemoglobin, lipid profile, fast glucose level or body mass index (BMI). There was, however, a reduction in waist circumference and in average self-monitored blood glucose levels, measured after each exercise session. In Group B, there were no changes in the parameters evaluated. In both groups the total insulin dosage was reduced. As other authors have shown, resistance/aerobic training did not improve glycated hemoglobin in type-1 diabetes patients.
