Background: This study aimed to investigate the effect of endurance and combination training on serum levels of Fetuin-A and metabolic syndrome of overweight and obese women. Materials and Methods: This was a semi-experimental study and 45 overweight and obese women were randomly divided into three groups: “ control” , “ aerobic exercise” and “ combined exercise” groups. The aerobic exercise and combined exercise groups were active for eight weeks. After blood sampling, Fetuin-A, high-density lipoprotein (HDL), lowdensity lipoprotein (LDL), triglyceride, total cholesterol and glucose were measured. Results: The results showed that after eight weeks in the aerobic and combined groups, Fetuin-A significantly increased (P=0. 022, P=0. 011). Also, LDL was significantly decreased in aerobic and combined groups (P=0. 006, P=0. 024). The results showed that the combined group had a significant decrease in TC, TG, FAT, BMI, and WHR compared to baseline and a significant increase in HDL (P<0. 05). Also, Fetuin-A decreased in aerobic and combined groups compared to the control group. The combined group showed a significant decrease in TC compared to the control and aerobic groups (P<0. 05). Besides, the combined group had lower TG, FAT, BMI, and WHR indices compared to the control group (P<0. 05). Conclusion: The results of this study showed that combined exercises compared aerobic training had significant decreasing effects on Fetuin-A, as well as metabolic syndrome indices in obese and overweight individuals and contributes to the improvement of the dangers of obesity and cardiovascular risk factors.
