Abstract

omentin-1 is a newly discovered adipokine with improving insulinsensitivity. The aim of this study was to investigate the effect of eight weeks of circuit resistance training on plasma omentin-1 levels in obese men. 28 obese men (mean age: 35. 7 ± 8. 0 yr, weight: 95. 5 ± 14. 3 kg, and BMI: 31. 8 ± 4. 3 kg/m2) voluntarily participated in this study, and were divided into control (n=12) and resistance training (n=16) groups. Subjects in training group performed 8 weeks of circuit resistance training with 50-85% 1RM (3 days/week). Blood samples were collected from all subjects before and after the training program. Anthropometric parameters, plasma fasting glucose, insulin, and omentin-1 levels, as well as Insulin resistance index (HOMAIR) were measured at the baseline and at the end of the study. Paired and independent sample t tests were used to analyze the data. The correlation of variables was determined by Pearson correlation coefficient. resistance training significantly reduced body weight, BMI and body fat percentage (P<0. 05). Significant reductions in plasma insulin concentration and HOMA-IR scores were found when compared with control group (P<0. 05). No significant changes were observed in plasma omentin-1 concentration. These findings indicated that resistance training did not affect plasma omentin-1 circulating levels despite changes in body composition and metabolic parameters. Therefore, it seems that other mechanisms other than changes in body composition and Insulin resistance may be involved in regulating plasma omentin-1 levels.
