Abstract
Aim: Adipokines are molecules secreted from adipose tissue that are related to insulin resistance, metabolic syndrome, diabetes and cardiovascular diseases. Therefore, the effect of 8 weeks of resistance training along with green tea extract (GTE) supplementation on the concentration of adipokines apelin and chemerin in obese women was investigated.
Method: Thirty untrained women with a body mass index (BMI) above 30 kg/m2 were selected from among obese women using a randomized, double-blind, placebo-controlled design method and were divided into three groups including training and green tea extract (GT), training and placebo consumption (PT) and green tea extract consumption (G). GT and G groups took 600 mg.kg-1 of GTE daily and PT group also took 600 mg of placebo for 8 weeks. The resistance training program consisted of 3 sessions per week for 8 weeks (60-70 minutes with an intensity of 65% to 80% of a one repetition maximum). Serum level of adipokines was measured using ELISA method.
Results: The results of ANOVA with repeated measures indicate a significant decrease in serum levels of apelin and chemerin in GT and PT groups compared to G. Also, a significant decrease in the level of these adipokines was observed in the post-test compared to the pre-test in all three groups. Conclusion: 8 weeks of GTE intake and resistance training decreased inflammatory adipokines in obese women, and the combinatory effect of resistance training with GTE was more effective than the other two conditions.
