چکیده

زمینه و هدف: به نظر می رسد که فعالیت بدنی بتواند از طریق افزایش تولید سطوح در گردش آیریزین، بر بهبود هموستاز گلوکز و چربی های خونی موثر باشد. لذا، هدف از پژوهش حاضر بررسی اثر هشت هفته تمرین هوازی بر سطح سرمی آیریزین، هموستاز گلوکز و چربی های خون دختران تمرین نکرده بود.
مواد و روش ها: این مطالعه نیمه تجربی در 20 زن داوطلب یکی از دانشگاه های شهر رشت در دو گروه انجام شد. گروه کنترل فعالیت های معمول روزمره خود را انجام دادند، اما گروه تجربی در تمرینات هوازی 65 دقیقه ای، سه جلسه در هفته به مدت مدت هشت هفته متوالی شرکت کردند. چربی های خونی، هموستاز گلوکز و آیریزین در گردش در ابتدا و بعد از 8 هفته مداخله ارزیابی شدند. بررسی داده توسط نرم افزار SPSS نسخه 22 در سطح معناداری 05/0P< انجام شد.
یافته ها: در گروه تمرینی، بعد از هشت هفته مداخله انسولین (02/0=p) و HOMA (04/0=p) کاهش و HDL-C (00/0=p) افزایش یافت، اما میزان قند خون ناشتا، تری گلیسرید، کلسترول، LDL-C و آیریزین تغییر معنی داری را نشان نداد (05/0p>). در گروه کنترل، به دنبال دوره هشت هفته ای مطالعه قند خون ناشتا (04/0=p)، انسولین (01/0=p)، HOMA (00/0=p)، تری گلیسرید (03/0=p) و آیریزین (03/0=p) افزایش یافتند. بعد از مداخله، شرکت کنندگانی که تمرینات ورزشی را انجام داده بودند، میزان کلسترول (00/0=p)، تری گلیسرید (02/0=p)، انسولین (00/0=p) و HOMA (00/0=p) کمتر و HDL-C (00/0=p) بالاتری در مقایسه با گروه کنترل داشتند.
نتیجه گیری: به نظر می رسد تمرین هوازی در زنان بی تحرک با بهبود هموستاز گلوکز و HDL-C به صورت مستقل از تغییرات آیریزین همراه است.

چکیده [English]

Background: It seems that exercise training can be effective in improving glucose homeostasis and blood lipids by inducing circulating level of irisin. Therefore, the purpose of this study was to evaluate the effect of eight week aerobic training on serum irisin, blood lipid and blood sugar in untrained women.
Materials and Methods: This semi- experimental study was conducted on 20 sedentary volunteer women among a university of Rasht city in two groups. The control group conducted the routine daily activities, but the experimental group participated in 65 min aerobic training, three times a week for eight consecutive weeks. Blood lipids, glucose homeostasis and circulating irisin were assessed at baseline, and after 8 weeks of interventions. Data were analyses using SPSS version 22 and A P-value of P< 0.05 was considered statistically significant.
Results: In the training group, insulin (p=0.02) and HOMA (p=0.04) were decreased and HDL-C (p=0.00) was increased following 8-weeks of intervention. However, there were no significant changes in fasting blood sugar, triglyceride, cholesterol, LDL-C and irisin (P>0.05). In the control group, fasting blood sugar (p=0.04), insulin (p=0.01), HOMA (p=0.00), triglyceride (p=0.03) and irisin (p=0.03) were increased following 8-weeks of study period. After intervention, participants undergoing exercise training had significantly lower cholesterol (p=0.00), triglyceride (p=0.02), insulin (p=0.00) and HOMA (P=0.00) and higher HDL-C (p=0.00) compared with the control group.
Conclusion: It seems that aerobic training in sedentary women is associated with an improvement in glucose homeostasis and HDL-C independently of the irisin changes.
