چکیده

 
هدف تحقیق حاضر، بررسی تاثیر 12 هفته تمرین هوازی فزاینده به همراه مکمل امگا بر سطوح سرمی کمرین و شاخص مقاومت به انسولین در زنان چاق غیر فعال بود. در این مطالعه نیمه تجربی، 32  نفر از زنان چاق غیر فعال (سن 3 ± 36 سال و شاخص  توده بدن 5.23 ± 35.52  kg/m2)، که هیچ گونه فعالیت بدنی منظمی نداشتند، به عنوان آزمودنی های تحقیق انتخاب و به طور تصادفی در چهار گروه 8 نفری:  تمرین (T)، تمرین - امگا (T-OM)، امگا (OM) و کنترل (C) تقسیم شدند. آزمودنی های گروه  T و T-OM تمرینات هوازی فزاینده را با شدت 60 تا 80% حد اکثر ضربان قلب هر فرد، سه جلسه در هفته و به مدت 12 هفته انجام دادند. همچنین آزمودنی های گروه T-OM و OM، هر هفته 7 کپسول هر کدام حاوی هزار میلی گرم امگا-3 و آزمودنی های گروه T و C نیز در همین مدت دارو نما مصرف کردند. نمونه های خونی ناشتایی قبل و بعد از 12 هفته تمرین هوازی و مصرف مکمل جمع آوری شد. نتایج آزمون آماری تحلیل واریانس دو راهه نشان داد، تعامل تمرین-  امگا منجر به کاهش معنادار سطوح سرمی کمرین )0/010 (P=، و بهبود شاخص مقاومت به انسولین
)0/010 (P=و گلوگز  )0/004 (P=در زنان چاق غیر فعال می شود. مداخله ی توام تمرین- امگا منجر به کاهش بیشتر سطوح سرمی کمرین ؛درمقایسه با اثر تمرین و امگا به صورت مجزا؛ در زنان چاق غیر فعال می شود، اما به نظر می رسد این تعامل در رابطه با بهبود بیشتر شاخص مقاومت به انسولین تاثیر کمتری داشته باشد.

چکیده [English]

The aim of this study was to examine the effect of 12 weeks of progressive aerobic training with omega supplement on serum levels of chemerin and insulin resistance in obese inactive women. In this semi-experimental study, 32 obese inactive women (age 36 ± 3 yr, body mass index 35.52 ± 5.23 kg/m2) who had no regular physical activity were selected as the sample and randomly divided into four groups of 8 subjects: training (T), training - omega (T-OM), omega (OM) and control (C). The subjects in groups T and T-OM performed progressive aerobic training at an intensity corresponding to 60-80% of maximum heart rate 3 days/week for 12 weeks. The subjects in groups T-OM and OM consumed 7 omega-3 capsules, each containing 1000 mg omega-3 every week and subjects in groups T and C consumed placebo during the same period. Fasting blood samples were taken before and after 12 weeks of aerobic training and supplementation. Results of two-way ANOVA demonstrated the interaction of training – omega significantly reduced serum levels of chemerin (P=0.010) and improved insulin resistance index (P=0.010) and glucose (P=0.004) in obese inactive women. Compared with the effect of training and omega separately, the combined intervention of training - omega led to a further reduction in serum levels of chemerin in obese inactive women, but this interaction appears to be less effective in relation to the further improvement of insulin resistance index.
