چکیده

زمینه و هدف: تمرین استقامتی هوازی به عنوان کارآمدترین شکل تمرین بدنی، آثار متابولیکی سودمندی بر بیماران چاق دارد و در کاهش التهاب مزمن مؤثر است. با توجه به نقش‏ کلیدی آپلین در تنظیم متابولیسم انرژی، شناخت سطوح آپلین در اختلالات وابسته به چاقی حائز اهمیت می‏باشد. هدف مطالعه تأثیر 12 هفته تمرین هوازی فزآینده بر مقادیر آپلین و شاخص‏ های التهابی TNF-α، IL-6 وCRP زنان چاق غیر فعال بود. روش تحقیق: در این مطالعه نیمه تجربی 30 زن چاق غیر فعال (سن 1/75±37/19 سال، شاخص توده بدن 2/42 ±35/01 کیلوگرم بر متر مربع) که هیچ گونه فعالیت بدنی منظمی نداشتند؛ به عنوان آزمودنی انتخاب شدند و به طور تصادفی به دو گروه 15 نفره تجربی و کنترل تقسیم شدند. آزمودنی های گروه تجربی تمرین هوازی فزآینده دویدن را با شدت 60 تا 80 درصد ضربان قلب بیشینه سه روز در هفته و به مدت 12 هفته انجام دادند. میانگین تقریبی زمان هر جلسه طی 12 هفته (از هفته اول تا آخر)، 60 دقیقه بود. نمونه‏ ها‏ی خونی ناشتا قبل و بعد از مطالعه جمع آوری شد. مقادیر پلاسمایی و سرمی نشانگرهای بیوشیمیایی با استفاده از کیت‏ ها‏ی تجاری و با روش الایزا سنجش‏ شدند. برای تعیین تفاوت موجود بین مقادیر پیش آزمون یا پس آزمون در هر گروه نیز از آزمون تحلیل واریانس دو طرفه 2×2 استفاده گردید. میزان معناداری 0/05≥p در نظر گرفته ‏شد‏. یافته ها: نتایج آزمون، کاهش معنادار مقادیر آپلین (p<0/001) و شاخص های التهابی TNF-α  (p<0/001) IL-6 (p<0/001)و CRP (p<0/001) را نشان داد که نتیجه تأثیر تمرین هوازی فزآینده بود. نتیجه گیری: انجام تمرین هوازی فزآینده به طور غیرمستقیم با کاهش توده چربی و به طور مستقیم با کاهش تولید سایتوکاین‏ ها در بافت چربی، منجر به کاهش بیشتر آپلین شده و می‏ تواند سازوکاری برای کاهش التهاب در زنان چاق غیر فعال باشد.

چکیده [English]

Background and Aim: Aerobic endurance training is the most efficient type of physical training. It indicate beneficial effects on obese subjects because of decreasing chronic inflammation. Apelin plays a key role in energy metabolism adjustment. Therefore it is important to study the levels of blood apelin in obese people. The aim of this study was to investigate the effects of 12 weeks of progressive aerobic training on the level of apelin, TNF-α, IL-6 and CRP in obese inactive women. Materials and Methods: In this semi-experimental study, 30 obese inactive women (mean age 37.19±1.75 yr, body mass index 35.01±2.42 kg/m2) with no regular physical training were selected. They were randomly divided into two groups (N=15) including training and control groups. The individuals in the training group performed a progressive aerobic training protocol including running 3 days a week during period of 12 weeks up to the 60 to 80 percent of maximum heart rate. The average of exercise duration in every session was approximately 60 minutes. Fasting blood samples were taken before and after protocol. The concentrations of biochemical markers in plasma and serum were measured by commercial ELISA kits. To extraction of results the two-way ANOVA 2×2 test was applied and the significance level was considered as p≤0.05. Results: Two-way ANOVA was demonstrated the significant decreases in levels of apelin (p<0.001), TNF-α (p<0.001), IL-6 (p<0.001) and CRP (p<0.001) after progressive aerobic training. Conclusion: Progressive aerobic training is related to reduction of fat tissue and cytokines production and consequently decreases in apelin levels. The apelin reduction can be considered as a well-known mechanism to decrease inflammation in obese inactive women.
