چکیده

فاکتور نوروتروفیک مشتق از مغز (BDNF) که از نظر ساختاری شبیه فاکتور رشد عصبی است، در قسمت هیپوکامپ تولید می‌شود و یکی از فاکتورهایی است که در دوران سالمندی در اثر فقدان فعالیت کاهش می‌یابد. کاهش BDNF بر حافظه، یادگیری و شناخت، ، جذب غذا و متابولیسم انرژی تأثیر می‌گذارد و سبب اختلال رفتاری می‌شود؛ با فعالیت ورزشی می‌توان این کمبود را جبران و حتی از بروز آلزایمر جلوگیری کرد. هدف از اجرای این پژوهش، بررسی اثر تمرینات پیلاتس بر سطح BDNF سرم در مردان سالمند بود. برای این منظور20 مرد سالمند به‌طور تصادفی در دو گروه تجربی و کنترل با میانگین سنی (گروه کنترل 67/2±65 سال، گروه تجربی 62/2±64 سال) و میانگین وزن (گروه کنترل 59/3±73 کیلوگرم، گروه تجربی 54/3±71 کیلوگرم) تقسیم شدند. از کلیۀ آزمودنی‌ها 24 ساعت قبل از شروع تمرینات و 24 ساعت پس از پایان دورۀ تمرینی، به‌صورت ناشتا خون‌گیری به‌عمل آمد. سپس گروه تجربی به مدت 12 هفته (هر هفته 5 جلسه و هر جلسه به مدت 60 دقیقه) برنامۀ ورزشی پیلاتس را دریافت کردند. درحالی‌که گروه کنترل هیچ مداخله‌ای دریافت نکردند و تنها پیگیری شدند. به‌منظور مقایسۀ درون‌گروهی از آزمون آماری t همبسته و برای مقایسۀ بین‌گروهی از t مستقل استفاده شد. یافته‌ها نشان داد که سطوح BDNF سرم در گروه تجربی در مقایسه با گروه کنترل به‌طور معناداری افزایش یافت (05/0>P). نتایج این تحقیق نشان می‌دهد که تمرینات پیلاتس به‌عنوان یک روش ایمن و مؤثر، سبب افزایش سطوح BDNF سرم مردان سالمند می‌شود. بنابراین، با توجه به اینکه BDNF در دوران سالمندی بر اثر بی‌تحرکی کاهش می‌یابد، می‌توان کمبود آن را با اجرای تمرینات کم‌هزینه و بی‌خطر پیلاتس جبران کرد.

چکیده [English]

Brain-derived neurotrophic factor (BDNF), which is structurally similar to nerve growth factor is produced in the hippocampus and is one of the factors that is reduced by age due to lack of activity. Reduced BDNF has effects on memory, learning and cognition, behavioral disorders, food intake and energy metabolism that can be compensated with exercise and the incidence of Alzheimer can be prevented. The aim of this study was to investigate the effect of Pilates exercise on serum BDNF level in elderly men.  20 elderly men were randomly divided into experimental and control groups with mean age (control: 65 ± 2.67, experimental: 64 ± 2.62) and mean weight (control: 73 ± 3.59, experimental: 71 ± 3.54). Fasting blood samples were collected 24 hours before and 24 hours after the end of protocol. Then, experimental group received Pilates exercise for 12 weeks, 5 sessions per week, and 60 minutes per sessions while the control group received no intervention but were followed. Paired t test was used for intragroup comparisons and independent t test was used for intergroup comparison. Findings showed that BDNF levels significantly increased in experimental group compared to control (P<0.05). The results of this study suggested that Pilates exercises as an effective and safe method increased serum BDNF levels in elderly men. Thus, as BDNF decreases in the elderly due to their sedentariness, it can be compensated by safe and cost-effective Pilates exercises.
