چکیده

هدف: آدیپوکاین‌ها، مولکول‌های مترشحه از بافت چربی هستند که با مقاومت به انسولین، سندروم متابولیکی، دیابت و بیماری‌های قلبی عروقی ارتباط دارند. بنابراین، تاثیر 8 هفته تمرین مقاومتی به همراه مصرف مکمل عصاره چای سبز (GTE) بر غلظت آدیپوکاین‌های آپلین و کمرین در زنان چاق مورد بررسی قرار گرفت. روش کار: در یک طرح نیمه تجربی، 30 نفر از زنان تمرین نکرده با شاخص توده‌بدنی (BMI) بالاتر از 30 کیلو گرم بر مترمربع از میان زنان چاق به صورت هدفمند و در دسترس و سپس به روش طرح تصادفی، دوسوکور کنترل شده با دارونما انتخاب شدند و به سه گروه شامل تمرین و مصرف عصاره چای سبز (GT)، تمرین و مصرف دارونما (PT) و مصرف عصاره چای سبز (G) تقسیم شدند. گروه‌های GT و G، روزانه 600 میلی گرم GTE و گروه PT نیز 600 میلی گرم دارونما به مدت 8 هفته مصرف نمودند. برنامه تمرین مقاومتی شامل 3 جلسه در هفته به مدت 8 هفته بود. اندازه-گیری سطح سطوح سرمی آدیپوکاین‌ها با استفاده از روش الایزا انجام شد. یافته ها: نتایج تحلیل واریانس با اندازه‌گیری مکرر حاکی از کاهش معنی‌دار سطح سرمی آپلین و کمرین درگروه‌های GT و PT نسبت به G می باشد. همچنین، کاهش معنی-داری در سطح این آدیپوکاینها در پس‌آزمون نسبت به پیش آزمون در هر سه گروه مشاهده شد. نتیجه‌‌گیری: 8 هفته مصرف GTE و تمرین مقاومتی سبب کاهش آدیپوکاین‌های التهابی در زنان چاق گردید و تمرین مقاومتی همراه GTE به صورت همزمان اثربخشی بیشتری نسبت به دوشرایط دیگر داشت.

چکیده [English]

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.
