Physical activity is one of the recommended therapeutic and preventive methods for type 2 diabetic patients with non-alcoholic fatty liver (NAFLD). The aim of current study was to compare the effects of interval and continuous aerobic exercise training on metabolic syndrome in type 2 diabetic patients with NAFLD
30 women (40 to 55 years old) with type 2 diabetes with NAFLD were randomly divided into three groups. The groups included: interval aerobic exercise group (mean weight 72.7 ± 7.4 kg) with 75-80% of maximum heart rate, continuous aerobic exercise group (mean weight 73 kg ± 8.2 kg) with severity of 60-75% of maximum heart rate, and control group (mean weight 79.2 ± 15.5 kg). The exercise training groups were performed exercises by cycle ergometer for 8 weeks and three days a week. The control group did not have regular exercise during the study. The Variables includes waist circumference, triglyceride levels, HDL cholesterol, blood pressure, fasting blood glucose and insulin. Descriptive statistics were used to calculate the mean and standard deviations of data. For analysis and comparison between groups, one-way ANOVA was used. The t-dependent test was used for intra-group compression (α≤0.05).
There were no differences in the descriptive characteristics of the subjects between the three groups in the pre-test. In the continuous training group, was significant changes in waist circumference (p=0.001), fasting blood glucose (p=0.038), systolic blood pressure (p=0.024) and diastolic (p=0.014) and insulin (P=0/027). In the continuous aerobic exercise group, changes in waist circumference (p=0.000), fasting blood glucose (p=0.003), triglyceride (p=0.016), HDL cholesterol (p=0.037), systolic blood pressure (P=0.016) and diastolic (p=0.018) and insulin (p=0.036) were significant. In control group, none of the variables was significant. No significant variables were found in the intergroup comparison.
Regarding the fact that interval aerobic exercise had the greatest effect on metabolic syndrome in type 2 diabetic patients with NAFLD. Aerobic exercise in two training groups improved further metabolic syndrome factors including waist circumference, blood glucose, some lipid profiles and insulin. Therefore, it is recommended that these patients do aerobic exercise, in particular interval aerobic exercise.
