Abstract
The aim of this study was to compare the effects of two frequencies of equal volume aerobic exercises and detraining following these exercises on resistin and adiponectin levels, hemoglobin glycosylate, insulin resistance and body composition in obese women with type 2 diabetes. 36 obese women with type 2 diabetes were randomly divided into three groups (each group, n=12): 1= LFT, 2= HFT, 3= control. Group LFT and HFT performed 8 weeks of aerobic exercises (LFT=3 sessions and HFT=6 sessions a week, with the same volume) with intensity of 60-75% of maximum heart rate. Blood samples, anthropometric and functional variables were measured at pretest, 48 hours later and two weeks after the last exercise session. Depended t test was used for within-group comparisons and ANCOVA test was used to investigate the differences among the groups. The within-group results showed that after 8 weeks of intervention, weight, body fat, BMI, adiponectin, glucose and glycosylated hemoglobin in LFT group and resistin, insulin, insulin resistance and maximal oxygen consumption in both experimental groups significantly decreased (P<0.05). Also, ANCOVA test results showed a significant difference among all studied groups in all research variables in the posttest (P<0.05) and in the body fat, BMI, adiponectin and insulin resistance in the sustainability stage (P<0.05). Regarding the results of this study, longer exercises can better control type 2 diabetes than repeated short-term physical training especially in obese people.
