Physical activity reduces the risk of cardiovascular disease by modification of inflammation. The purpose of present study was to compare the effect of 8 weeks high intensity interval and moderate-intensity aerobic continuous training on predictive factor of heart failure in sedentary postmenopausal women. In this study, 30 healthy sedentary postmenopausal women (mean ± SE: age, 55.45 ± 0.49 years; weight, 71.26 ± 1.59 Kg) were selected in Isfahan and the subjects were randomly divided into three groups high intensity interval training, moderate-intensity aerobic continuous training and control. The high intensity interval training group participated in an exercise program at 60–90% of heart rate reserve and the moderate-intensity aerobic continuous training group participated in an exercise program at 50–65% of heart rate reserve but the control group did not participate in any regular physical activity program during this period. C-reactive protein and lipid profiles were compared using repeated measure ANOVA before and after 8 weeks in three groups. The results showed a significant decrease in C reactive protein and increase in high intensity lipoprotein of high intensity interval training group in comparison of other groups. A significant increase in HDL-C/LDL-C was seen in both training groups compared to the control group. Results of this study showed that high intensity interval training have more effective role than moderate-intensity aerobic continuous training exercises in preventing of cardiovascular diseases in postmenopausal women.
