چکیده

افزایش مقادیر پلاسمایی FIB(فیبرینوژن)، TNFα (عامل نکروز تومور آلفا)، IL-6(اینترلوکین 6)،HCY(هموسیستئین) وCRP(پروتئین واکنشیc ) به عنوان شاخص های خطر بیماری های قلبی ـ عروقی شناخته شده­اند . از این رو هدف، پژوهش حاضر بررسی تاثیر 8 هفته برنامه تمرین هوازی بر شاخص های خطر بیماری های قلبی ـ عروقی در زنان چاق غیر فعال بوده است. 20 زن چاق غیر فعال باKg/m230 BMI ≥ انتخاب و به طور تصادفی در دو گروه تمرین هوازی و کنترل داوطلب شرکت در پژوهش حاضر شدند. برنامه تمرینی به مدت 8 هفته، هفته ای سه جلسه، هر جلسه به مدت 30 دقیقه با 60 تا 65 درصد ضربان قلب بیشینه اجرا شد. از گروه تمرین هوازی و کنترل، قبل و بعد از اتمام برنامه تمرینی در شرایط ناشتا برای سنجش مقادیر متغیرهای پژوهشی با استفاده از روش آزمایشگاهی آنزیم ایموانسی (ELISA) نمونه گیری خونی به عمل آمد. داده های پژوهش با استفاده از آزمون آماریt  همبسته و t مستقل در سطح معناداری (05/0P<) تجزیه و تحلیل شدند. نتایج تحلیل آماری نشان داد برنامه تمرین هوازی به طور معناداری میزان HCY (001/0p= FIB(001/0p=TNFα (002/0p=IL-6(038/0p=) و CRP(001/0p=) زنان چاق را کاهش می دهد. همچنین، نتایج آزمون t مستقل نیز نشان داد بین دو گروه تمرین هوازی و کنترل در متغیرهای پژوهشی تفاوت معناداری وجود دارد (05/0P<). یافته های پژوهش حاضر نشان داد یک برنامه 8 هفته ای تمرین هوازی کنترل شده و منظم می تواند نقش موثری در کاهش مقادیر شاخص های التهابی بیماری قلبی ـ عروقی در زنان چاق داشته باشد .

چکیده [English]

The rise in plasma levels of FIB (fibrinogen), TNFα (tumor necrosis factor-alpha), IL-6 (Interleukin-6), HCY (homocysteine), and CRP (C-reactive protein) are known to be indexes of risk factors for cardiovascular events. The aim of the present study was to investigate the effect of 8 weeks of an aerobic exercise program on indexes of risk factors for cardiovascular events in inactive obese women. 20 inactive obese women with BMI≥30 kg/m2 were volunteered to take part in this study and were randomly divided into two groups of aerobic and control. The exercise program consisted of 8 weeks, three sessions per week, each session 30 min. with 60-65% MHR. Before and after the exercise protocol, blood samples of both groups (in fasting state) were collected by ELISA method to measure the variables under study. The data were analyzed through paired t test and independent t test (P<0.05). The results revealed that aerobic exercise program significantly decreased HCY (P=0.001), FIB (P=0.001), TNFα (P=0.002), IL-6 (P=0.038), and CRP (P=0.001) in obese women. Also, the results of independent t test indicated a significant difference between aerobic exercise and control groups in research variables (P<0.05). The results showed that a regular and controlled 8-week aerobic exercise program can play an effective role in reducing inflammatory markers of cardiovascular events in obese women.
