Changes of visfatin concentration, insulin resistance index and lipids profile following 10 weeks of swimming endurance training in obese women

Abstract

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). 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.
