The aim of this study was to examine the effect of 12 weeks of progressive aerobic training with omega supplement on serum levels of chemerin and insulin resistance in obese inactive women. In this semi-experimental study, 32 obese inactive women (age 36 ± 3 yr, body mass index 35.52 ± 5.23 kg/m2) who had no regular physical activity were selected as the sample and randomly divided into four groups of 8 subjects: training (T), training - omega (T-OM), omega (OM) and control (C). The subjects in groups T and T-OM performed progressive aerobic training at an intensity corresponding to 60-80% of maximum heart rate 3 days/week for 12 weeks. The subjects in groups T-OM and OM consumed 7 omega-3 capsules, each containing 1000 mg omega-3 every week and subjects in groups T and C consumed placebo during the same period. Fasting blood samples were taken before and after 12 weeks of aerobic training and supplementation. Results of two-way ANOVA demonstrated the interaction of training – omega significantly reduced serum levels of chemerin (P=0.010) and improved insulin resistance index (P=0.010) and glucose (P=0.004) in obese inactive women. Compared with the effect of training and omega separately, the combined intervention of training - omega led to a further reduction in serum levels of chemerin in obese inactive women, but this interaction appears to be less effective in relation to the further improvement of insulin resistance index.
