    Abstract:
    BACKGROUND: Omentin, chemerin and vaspin are novel adipokines that are secreted from adipose tissue and improved insulin sensitive. The purpose of this study was to examine the effects of rhythmic aerobic exercise plus core stability training on serum omentin, chemerin and vaspin levels and insulin resistance (IR) of overweight women. METHODS: Forty aged healthy women (age; 25-45 years old, waist circumference [WC]>88 cm; Body Mass Index (BMI)>25 kg/m2) were selected purposely and divided in two control (N.=16) and experimental (N.=19) groups. Five dropped out during the study. The experimental group trained 12 weeks (3 sessions per week, one hr/session). The exercise program consisted of rhythmic aerobic exercise (55-85% maximum heart rate) along with core stability training. Serum chemerin, omentin, vaspin and insulin concentration were assayed by commercially ELISA kit. IR was evaluated according to the Homeostasis Model Assessment of Insulin Resistance Index (HOMA-IR). Data were analyzed by dependent and independent t-test to compare pre-test and post-test in each group and to compare the amount of changes in experimental and control training groups after twelve weeks. RESULTS: The result showed that exercise training had significant effect on BMI (P=0.00), WC (P=0.00), body fat (P=0.05), chemerin (P=0.041) and vaspin (P=0.045). But, this training had non-significant effect on plasma omentin level (P=0.090), plasma glucose level (P=0.670), insulin (P=0.11) and IR (P=0.07). CONCLUSIONS: Despite the fact that this kind of intervention could be an effective treatment to improve some adipokine levels and was accompanied by decreased body fat and waist circumference. However, more intense training is required to significantly change IR and serum omentin level in overweight women.
