چکیده
زمینه و هدف: چاقی و اضافه وزن در دوران کودکی و نوجوانی از اهمیت ویژهای برخوردار است. بنابراین، هدف از تحقیق حاضر بررسی تاثیر 10 هفته تمرین ترکیبی بر میزان کمرین، آیریزین، مقاومت به انسولین و نیمرخ لیپیدی در دختران دارای اضافه وزن بود. روش تحقیق: تعداد 24 نفر از دانش آموزان دختر دارای اضافه وزن (با میانگین سنی 62/0±23/11 سال و شاخص توده بدن 48/0±97/27 کیلوگرم بر مترمربع) به صورت تصادفی ساده به دو گروه کنترل (12=n) و تمرین ترکیبی (12=n) تقسیم شدند. آزمودنی های گروه تجربی به مدت10 هفته به اجرای برنامه تمرین ترکیبی پرداختند و گروه کنترل نیز بدون مداخله تمرینی به فعالیت های روزانه خود مشغول بودند. اندازه گیری آیریزین، مقاومت به انسولین و نیمرخ لیپیدی (کلسترول، تری گلیسیرید، لیپوپروتئین با چگالی کم و بالا) قبل و پس از پایان پروتکل تحقیق انجام گرفت. برای تجزیه و تحلیل آماری از آزمون کوواریانس استفاده شد و سطح معنیداری نیز 05/0 p≤ در نظر گرفته شد. یافته ها: نتایج پژوهش حاضر نشان داد که 10 هفته تمرین ترکیبی باعث کاهش معنی دار کمرین، انسولین، کلسترول، تری گلیسیرید و LDL-C شد (001/0>p). با این حال، مقادیر آیریزین، گلوکز و HDL-C تحت تاثیر تمرین ترکیبی قرار نگرفت (به ترتیب، 18/0=p، 37/0=p، 06/0=p). نتیجه گیری: تمرینات ترکیبی میتواند به عنوان بخشی از برنامه ورزشی دختران دارای اضافه وزن توصیه شده و جایگزین مناسبی برای تمرینات مرسوم هوازی باشد.

چکیده [English]
Background and Aim:Obesity and overweight in children and adolescence is very important. So, the aim of this study was to investigate the effects of 10 weeks of concurrent training on chemerin, irisin, insulin resistance and lipid profile in children girls with overweight. Materials and Methods: Twenty- four obese children girls (mean age=11.23±0.62 y. and body mass index=27.97±0.48 kg/m2) was divided into control (n=12) and concurrent training (n=12) groups. Training group underwent concurrent training for 10 weeks while control group performed daily activity. Chemerin, irisin, insulin resistance and lipid profile (cholesterol, triglyceride, low- density lipoprotein and high- density lipoprotein cholestrol) were measured before and after study protocol. It is applied the ANCOVA test for statistical analysis at the significant level of p<0/05. Results: Ten weeks of concurrent training significantly decreased level of chemerin, insulin resistance, cholesterol, triglyceride and LDL-C (p<0.001); however, irisin, glucose and HDL-C concentration didn’t affect by concurrent training (p=0.18, p=0.37, p=0.06 respectively). Conclusion:concurrent training could suggest as part of exercise training in overweight children girls and it may be an alternative training for traditional aerobic training.
