Purpose: it has been determined that physical activity ameliorates inflammatory status caused by obesity andaging process. This study investigated effect of swimming endurance training on serum visfatin levels, insulinresistance index (HOMA-IR) and lipids profile in obese women. Methodology: Participants included 16sedentary post menopausal obese women (BMI=30.16±1.15 kg/m2, mean aged 54.25±3.9 years) randomlyassigned to two experimental and control groups, participated in 10 weeks of swimming endurance training(50-60% of maximal heart rate), 3 days per week. Serum visfatin levels, HOMA-IR, lipids profile andanthropometric measurements were assessed before and 48 hours after training. Statistical analysis was doneby paired and independent t -test and Pearson correlation, and P value < 0.05 was considered significant.Results: 10 weeks of endurance training reduced visfatin level (P=0.045, 28.5%) and HOMA-IR (P=0.005,34.85%) and improved lipids profile and anthropometric indices (P<0.05). Although Pearson correlationshowed significant correlations between the primary concentrations of visfatin and primary levels of TG(P=0.044, r=0.720) and HDL-C (P=0.032, r= -0.750), no significant correlations existed between changes invisfatin levels and changes in none of variables assessed (P>0.05). Hence, changes in HOMA-IR hadsignificant correlations with changes in weight (P=0.002, r=0.898), BMI (P=0.000, r=0.942) and waistcircumference (P=0.002, r=0.906). Conclusion: Endurance training reduces visfatin concentration andimproves lipids profile and body composition in sedentary postmenopausal obese women.
