چکیده

هدف: افزایش سن، عوامل التهابی و سندروم متابولیک از عوامل موثر در کاهش BDNF و حافظه‌ی کوتاه‌مدت می‌باشد. هدف از این تحقیق بررسی اثرگذاری 12 هفته تمرین هوازی با شدت متوسط بر سطوح BDNF و حافظه کوتاه مدت زنان 50-65 ساله‌ی مبتلا به سندروم متابولیک می‌باشد. روش: 24 زن مبتلا به سندروم متابولیک به طور داوطلبانه در این تحقیق شرکت کردند. آزمودنی‌ها به طور تصادفی به دو گروه 12 نفره تمرین و کنترل تقسیم شدند. گروه تمرین هفته اول سه ست 8 دقیقه ای با فواصل استراحت پنج دقیقه با شدت 60 تا 70 درصد از ضربان قلب ذخیره ای تمرینات خود را روی تردمیل انجام دادند. با سپری شدن هر هفته، یک دقیقه به مدت زمات ست­های تمرین افزوده می­شد. قبل و پس از 12 هفته تمرین جهت اندازه‌گیری سطوح BDNF نمونه‌گیری خونی انجام شد. میزان سطوح BDNF توسط رادیوایمونواسی، میزان حافظه کوتاه مدت نیز توسط آزمون یادداری عددی مورد بررسی قرار گرفت. برای تجزیه تحلیل داده‌ها از ضریب همبستگی پیرسون، تی مستقل و تی جفتی استفاده گردید. یافته: BDNF و حافظه کوتاه مدت پس از 12 هفته تمرین هوازی نسبت به پیش آزمون بطور معنی‌داری افزایش یافتند (05/0˂P). همچنین هیچ تغییری معنی‌داری در سطوح BDNF (09/0=P) و حافظه کوتاه مدت (16/0=P) قبل از تمرین و پس از تمرین گروه کنترل مشاهده نگردید. نتیجه‌گیری: در اثر 12 هفته تمرین هوازی با شدت متوسط میزان سطوح BDNF افزایش یافت و این افزایش موجب بهبود عملکرد حافظه کوتاه مدت گردید.

The Effect of three month aerobic exercise whit moderate intensity on BDNF, and cognitive performance in 50-65 years old women with syndrome metabolic

چکیده [English]

Aim: The aim of this research was investigation the effect of twelve week aerobic exercise whit moderate intensity on on BDNF, and cognitive performance in 50-65 years old women with syndrome metabolic.
Methods: 24 women with metabolic syndrome (MetS) took part voluntarily and divided in tow group MetS exercise (ME), MetS control (MC). ME group participated in an aerobic exercise training (AT) program (12 weeks), tree session per week, each session contain tree performing part and tow rest part. Also blood samples were conducted before and after training for evaluate levels of BDNF. Cognitive performance measured by Digit span memory test. Data were analyzed using Pearson coefficient, pried-sample T-Test, and independent samples T-Test.
Results: BDNF and cognitive performance after tree month aerobic exercise significantly changed (P˃0.05). BDNF and cognitive performance after tree month in control group didn’t significantly changed (P
