چکیده

پژوهش حاضر به صورت بالینی و با هدف مقایسه تأثیر دو روش تمرینی حرکتی-شناختی بر کارکردهای اجرایی سالمندان دارای اضافه وزن انجام شد. شرکت کنندگان تعداد 30 نفر از سالمندان 65 تا 80 ساله (میانگین سنی72 سال) شهر تهران بودند که از طریق نمونه گیری هدفمند انتخاب شدند. ﻳﻚ ﻫﻔﺘﻪ ﻗﺒﻞ پیش آزمون (بازداری پاسخ، حافظه کاری و حل مسئله) به عمل آمد سپس به طور تصادفی به دو گروه تمرینات تکلیف منفرد (15 نفر) و تکلیف دوگانه (15 نفر) تقسیم شدند. پس از پایان جلسه دوازدهم پس آزمون به عمل آمد و دو ماه بعد نیز آزمون پیگیری گرقته شد. از آزمون‌ آماری تحلیل واریانس مکرر برای ارزیابی یافته‌ها استفاده شد. نتایج نشان داد اختلاف معناداری در کارکردهای اجرایی در سه زمان پیش آزمون، پس آزمون و آزمون پیگیری وجود دارد. اما اثر تعاملی دو فاکتور گروه و زمان معنادار نیست. بنابراین دو روش تمرینی بر کارکرد اجرایی سالمندان دارای اضافه وزن اثر یکسانی دارند.

چکیده [English]

The purpose of this study was to investigate the effect of motor- cognitive dual task on executive functions in overweight elderly. Participants were 30 elderly (65-80 years M=72) of Tehran city. After the pretest (response inhibiation, working memory, problem solving) they were taken in two groups, single task group (n=15) and dual task group (n=15 (for 12 sessions. After the last session, the posttest were taken. Repeated measure of ANOVA were used to analyze the data. Results showed the participants` executive functions improved from pre-test to post-test and follow up. But the interactive effect of the two factors of group and time is not significant. Therefore, the two training methods have the same effect on the executive function of overweight elderly people.
