چکیده

تمرین ورزشی به بهبود آسیب عملکرد پروتئین‌ها و آنزیم‌های میتوکندری در سالمندی منجر می‌شود. هدف پژوهش حاضر تاثیر 12 هفته تمرین تناوبی خیلی شدید (HIIT) بر بیان پروتئین‌های میتوکندریایی PGC-1α, SIRT1 ERRα, در رت‌های سالمند بود. در این مطالعه تعداد 30 رت نژاد ویستار سالمند به صورت تصادفی به دو گروه HIIT و گروه کنترل (CTR) تقسیم شدند. تمرین ورزشی در گروه HIIT در هفته اول 16 دقیقه (2 دقیقه با شدت 85 تا 90 درصد VO2max و 2 دقیقه با شدت 45 تا 50 درصد VO2max) آغاز شد و به تدریج تا هفته دوازدهم به 28 دقیقه رسید. مقادیر بیان پروتئین-های PGC-1α, SIRT1 و ERRα عضله دو قلو به روش وسترن بلات سنجیده شد. از روش آماری تی مستقل برای تجزیه تحلیل داده‌ها استفاده شد. وزن بدن و وزن عضله دو قلو بعد از 12 هفته HIIT تفاوت معنا داری نداشت. بیان پروتئین PGC-1α و ERRα در گروه HIIT در مقایسه با گروه کنترل افزایش معناداری داشت (p <0.001). بیان پروتئین SIRT1 در گروه HIIT در مقایسه با گروه کنترل افزایش معناداری داشت (p <0.01). به نظر می رسد HIIT به وسیله شدت بالا و ماهیت تمرین تناوبی باعث افزایش بیان پروتئین‌های PGC-1α, Sirt1 ERRα, عضله دوقلو رت‌های سالمند شده است.

چکیده [English]

Exercise training improved impaired mitochondrial protein and enzymatic functional induced aging. The purpose of this study was to investigate the effects of 12-weeks of high-intensity interval training on mitochondrial proteins of SIRT1, PGC-1α and ERRα in gastrocnemius muscle in aged rats. In this study 30 aged Wistar rats were randomly divided into HIIT and control group. Exercise training was performed 3 days per week for 8-weeks. Exercise training in the HIIT group was started in the first week by 16 minutes (four intervals (T=2min) at 85-90% VO2max with 4 recovery periods (T=2min) at 45-50% VO2max), which reached 28 minutes in the 12th week. Gastrocnemius was removed 48 h after the final training session. The expression levels of SIRT1, PGC-1α and ERRα proteins in gastrocnemius were assessed by Western blot method. Data analysis was done with independent samples t test. There were no significant differences in body weight and gastrocnemius muscle weight after the intervention. The protein expression of PGC-1α and ERRα were significantly increased in the HIIT compared to control group (p < 0.001). Moreover, SIRT1 expression was significantly elevated in the HIIT compared to control group (P <0.01). It seems that HIIT due to its high intensity and interval nature leads to an increased expression of SIRT1, PGC-1α and ERRα proteins in the gastrocnemius muscle of aging rat models.
