Abstract :
Background: The term diabetes mellitus describes a metabolic disorder of hyperglycemia with disturbances of carbohydrate metabolism resulting from defects in secretion and action of insulin. The aim of this study was to investigate the effects of aerobic exercise on physical fitness indices and the amount of insulin taken in boys with type 1 diabetesMethods: For this purpose, 64 adolescents boy with diabetes type I were selected and were divided into 2 groups: Aerobic training group (AE) (n = 32) and control group (CO) (n = 32).Aerobic training group did aerobic exercises for 6 weeks (3 days a week), while the control group did not do any exercise. Training program consisted of: a) warm-up (10 minutes); b) the original class (30 minutes); c) cooling (5 minutes). At first both groups performed fitness physical tests that include of flexibility (sit and reach test), muscular endurance test (sit-up test), aerobic capacity test (run 6 minutes’ walk), agility test (T-test) and anaerobic capacity (Running-based Anaerobic SprintTest), also were recorded the amount of insulin consumption as a pre-test and then after six weeks both groups performed the same tests as a post-test.Result: The results showed that 6 weeks of aerobic training has a significant effect in increasing agility, flexibility, muscular endurance, aerobic power and anaerobic power in boys with type I diabetes (p<0.05). In addition, aerobic exercise group significantly reduced the amount of insulin than the control group (p<0.05).Conclusion: The result of this study showed that the application of aerobic exercise is effective for improvement of physical fitness indices. This may reduce the amount of insulin in children and adolescents with type 1 diabetes and they are more likely to participate in sports activities.
