Effect of 8 Weeks Aerobic Interval Training on Glycosylated Hemoglobin and Insulin Resistance Index in Diabetic Mellitus Type 2 Women

Abstract

Aims Any increase in the glycosylated hemoglobin (HbA1c) implies improper glucose control in the diabetic persons. Based on the evidences, a reduction in HbA1c prevents the long-term side-effects of diabetes. The aim of this study was to investigate the effects of 8-week aerobic alternate exercises on HbA1c and insulin resistance index in women with type II diabetes. Materials & Methods In this semi-experimental study, 30 women with type II diabetes referred to the diabetes clinic of Ahwaz Golestan Hospital were studied in 2012 The subjects were selected via available sampling, and randomly divided into experimental and control groups (n=15 per group). The aerobic program consisted of 8-week pedaling on an ergometer bicycle with an intensity of 68 to 80% of maximum power (3days per week). Fasting blood sampling was done before and after the exercise sessions in all the subjects. Data was analyzed by SPSS 17 software using dependent T and covariance analysis test. Findings Following 8-week aerobic alternate exercises, there was no significant reduction in HbA1c and fasting glucose in experimental group (p>0.05). Nevertheless, there were significant reductions in serum insulin and insulin resistance (p<0.05). There was no significant difference between fasting glucose and HbA1c amounts in experimental and control groups. Nevertheless, there were significant differences between serum insulin and insulin resistance in both groups (p<0.05). Conclusion 8-week aerobic alternate exercises with an increasing intensity affect serum insulin level and insulin resistance index in the women with type II diabetes. Nevertheless, the exercises do not considerably affect fasting blood glucose and HbA1c amount. A B S T R A C T A R T I C L E I N F O
