چکیده

مقدمه
انجام انواع تمرین­های ورزشی به همراه مصرف مکمل­های گیاهی، به­عنوان شیوه­ای مهم درکنترل و پیشگیری از چاقی توصیه شده است. هدف از تحقیق حاضر بررسی اثر 8 هفته تمرین ایروبیک موزون با شدت متوسط به همراه مصرف مکمل چای­سبز بر برخی شاخص­های متابولیکی و ترکیب بدنی زنان چاق بود.
روش کار
در این مطالعه نیمه تجربی، 30 زن چاق غیرفعال، به­طور هدفمند بر اساس شاخص توده بدن (BMI) انتخاب شدند. سپس به­طور تصادفی در سه گروه 10 نفری شامل گروه تمرین ایروبیک موزون به­همراه مصرف مکمل چای­سبز (BMIمعادل28/2±69/35کیلوگرم/مترمربع)، تمرین ایروبیک موزون (BMIمعادل25/2±18/36کیلوگرم/مترمربع) و کنترل (BMIمعادل02/3±65/34کیلوگرم/مترمربع) تقسیم شدند. پروتکل تمرین ایروبیک موزون به صورت 8 هفته و 3 جلسه در هفته برای هر دو گروه تجربی اجرا شد و گروه مکمل روزانه، کپسول حاوی 500 میلی­­گرمی چای­سبز دریافت کردند. متغیرهای متابولیکی و ترکیب­بدنی در مراحل پیش­آزمون و پس­آزمون اندازه­گیری شدند. نتایج با استفاده از آزمون­های t همبسته، تحلیل کوواریانس و آزمون تعقیبی بونفرونی در سطح معنی­داری 05/0>p استخراج گردید.
نتایج
اجرای 8 هفته تمرین ایروبیک موزون با و بدون مصرف مکمل چای­سبز، باعث کاهش معنی­دار (05/0>p) در وزن  و BMI (هر دو به­ترتیب 3% و 2%)، دورکمر (به­ترتیب 4% و 1%)، سطوح سرمی گلوکز (به­ترتیب 7% و 5%)، تری­گلیسرید (به­ترتیب 11% و 4%) و مالون­دی­آلدئید MDA (به­ترتیب 25% و 9%) شد.
نتیجه ­گیری
هر چند تمرین ایروبیک موزون موجب بهبود شاخص­های سطوح سرمی­تری­گلیسرید، گلوکز، MDA و ترکیب­بدنی زنان چاق شد؛ تمرین ایروبیک موزون به همراه مصرف مکمل چای­سبز، تاثیر کاهشی بیشتری بر دور کمر، سطوح ­سرمی تری­گلیسرید و MDA داشت.

چکیده [English]

Introduction: Exercising with herbal supplements is recommended as an important way to control and prevent obesity. The aim of the study was to evaluate 8 weeks moderate intensity rhythmicaerobic exercise with green tea supplementation on some of metabolic and body composition indices of obese women.
Materials and Methods: In the semi-experimental study, 30 inactive obese women, purposefully, based on body mass index (BMI) were randomly divided into 3 groups of 10 people. They were rhythmic aerobic exercise with green tea supplement group (Experimental1, BMI:35.69±2.28 kg/m2), rhythmic aerobic exercise group (Experimental2, BMI:36.18±2.25 kg/m2) and control group (BMI:34.65±3.02 kg/m2). The rhythmic aerobic exercise protocol was performed 8 weeks and 3 sessions per week for both experimental groups. The supplement group received one capsule containing 500 mg of green tea daily. Metabolic and body composition indices were measured in pre-test and post-test stages. Paired t-tests, covariance analysis and bonferroni post hoc test were used for data analysis (p<0.05).
Results: Eight weeks of rhythmicaerobic exercise with and without green tea supplement led to significant decrease (p<0.05) in body weight and BMI (both of them respectivly 3%,2%), waist circumference(respectivly 4%,1%), serum glucose(respectively 7%,5%), triglyceride (respectively 11%,4%) and malondialdehyde (MDA) (respectivly 25%,9%).
Conclusions: However, rhythmic aerobic exercise improved body composition and serum levels of triglycerides, glucose and MDA in obese women; rhythmic aerobic exercise with green tea supplement had a more significant effect on the waist circumference, serum levels of triglyceride and MDA.
