A Comparison of Moderate Intensity Continuous Training and High Intensity Interval Training on Serum Levels of Resistin and Insulin Resistance in Type-2 Diabetic Obese Women

The present study intended to compare two types of aerobic training on serum levels of resistin and insulin resistance in type-2 diabetic women. 24 middle-aged type-2 diabetic women (mean age 41.8±3.45 yr, weight 76.8±3.61 kg, BMI 31.1±1.02 kg/m2, body fat percentage 41.6±1.38 and WHR 0.94±0.05) were purposively selected and then randomly assigned to three groups: highly-intensity interval training, moderate-intensity endurance training and control. The two experimental groups performed the training protocol for 16 weeks, 3 sessions per week. After 12 hours of fasting, blood samples were collected and serum resistin concentration and insulin were measured. The data were analyzed by Kolmogorov –Smirnoff test, one-way ANOVA, Bonferroni post hoc test and paired t testat the significance level of P>0.05. Findings showed no significant statistical difference between highly-intensity interval training and moderate-intensity endurance training in serum resistin and insulin resistance. Both types of training significantly reduced resistin, insulin resistance, BMI and body fat percentage (P>0.05), but they could not significantly change WHR (P>0.05). The results showed no significant differences between 16 weeks of highly-intensity interval training and moderate-intensity endurance training in resistin, anthropometric index and insulin resistance. Both types of training can improve insulin resistance and reduce serum resistin. This reduction can signal the reduction of cardiovascular and metabolic risk factors.
