| چکیده | ||
| شواهد بسیاری از مطالعات انسانی و حیوانی وجود دارد، مبنی بر اینکه ورزش تأثیرات سودمندی بر سیستم عصبی مرکزی و شناخت دارد. ازاین‌رو هدف از پژوهش حاضر، تعیین تأثیر فعالیت ورزشی مقاومتی بر حافظه و سازوکارهای احتمالی این اثر، یعنی عوامل نوروتروفیکی دانشجویان کم‌تحرک بود. بدین منظور 30 دانشجوی کم‌تحرک (میانگین سنی 6/1±8/23 سال)، به‌صورت تصادفی به دو گروه مقاومتی و کنترل تقسیم شدند، و بعد از نمونه‌گیری خونی و آزمون حافظه، تمرینات خود را براساس پروتکل تمرین مقاومتی، به مدت پنج هفته ادامه دادند. در پایان، آزمون حافظه و نمونه‌گیری خونی، به‌منظور حذف آثار موقت تمرین، حداقل 48 ساعت پس از آخرین جلسۀ تمرین به‌عمل آمد. برای تجزیه‌وتحلیل داده‌ها از آزمون‌های تحلیل کوواریانس و ضریب همبستگی پیرسون، در سطح معناداری 05/0> P استفاده شد. نتایج نشان داد تمرین به پیشرفت معنادار نمرۀ حافظه منجر شد (05/0>P)؛ هرچند میزان BDNF پیشرفت شایان توجهی در اثر تمرین داشت، بیان هیچ‌یک از عوامل نوروتروفیکی تحت تأثیر تمرین قرار نگرفت (05/0>P). همچنین نتایج نشان داد همبستگی بین تغییرات نمرۀ حافظه و بیان هیچ‌یک از عوامل نوروتروفیکی از نظر آماری معنادار نبود (05/0>P). یافته‌های این تحقیق نشان داد فعالیت ورزشی می‌تواند به بهبود حافظه منجر شود. | ||

| چکیده [English] | ||
| There are evidences in both animal and human studies which show that exercise has beneficial effects on the central nervous system and cognition. So, the aim of this study was to investigate the effect of resistance exercise on memory and probable mechanisms of this effect (i.e. neurotrophic factors) in sedentary students. 30 sedentary students (mean age, 23.8±1.6 yr) were randomly divided into two groups: control and resistance. After blood sampling and memory test, they continued their exercises for 5 weeks based on the resistance training protocol. In the end, at least 48 hours after the last training session, the memory test and blood samples were collected in order to eliminate the temporary effects of exercises. For analysis of the data, Covariance test and Pearson correlation coefficient were used (P≥0.05). Results showed that resistance exercises significantly increased memory score (P<0.05). Although BDNF significantly increased after the exercises, the exercises did not influence the expression of any neurotrophic factors (P˂0.05). Furthermore, there was no significant correlation between variations of memory scores and variations of expression of neurotrophic factors (P˂0.05). The findings indicated that exercise can improve memory. | ||
