چکیده

هدف: به نظر می‌رسد با افزایش سن، سرعت و میزان ساخت پروتئین‌های انقباضی و سنتز پروتئین های میتوکندریایی عضلات کاهش می‌یابد. هدف از پژوهش حاضر بررسی تأثیر هشت هفته تمرین مقاومتی فزاینده و مکمل کراتین هیدروکلراید بر بیان ژن مایوژنین و HSP70 عضله سولئوس رت‌های نر سالمند بود.
روش‌شناسی‌: 32 سر موش صحرایی نر 24 ماهه در 4 گروه کنترل، مکمل (کراتین HCL)، توام (تمرین مقاومتی+ مکمل) و تمرین تقسیم شدند. تمرین مقاومتی شامل هشت هفته تمرین نردبان با شدت متوسط (70 درصد از MVCC) و پنج روز در هفته بود. در گروه‌های مکمل و توام 5 روز در هفته و به مدت 8 هفته، مکمل کراتین هیدروکلراید و به میزان 200 میلی گرم به ازای هر کیلوگرم وزن بدن به صورت گاواژ دریافت شد. مایوژنین و HSP70 با استفاده از روش Real-time PCRبه دست آمد. تجزیه و تحلیل ﺁﻣﺎری با تحلیل واریانس دوطرفه، یکطرفه ﻭ ﺁﺯﻣﻮﻥ تعقیبی توکی انجام شد.
یافته‌ها: نتایج بیانگر افزایش معنی‌دار بیان ژن HSP70 و مایوژنین عضله سولئوس در گروه توام نسبت به گروه‌های مکمل و کنترل بود (001/0=p). تفاوت معنی داری بین دو گروه کنترل و مکمل مشاهده نشد (158/0=p).
نتیجه‌گیری: به نظر می‌رسد افزایش HSP70 و مهار آپوپتوز عضلانی ناشی از سارکوپنی و افزایش عملکرد میتوکندری و همچنین تاثیر افزایش یافته مایوژنین بر هیپرتروفی عضلانی و ایجاد یک محیط آنابولیک برای رشد عضلات در سنین سالمندی نشان دهنده اهمیت تمرینات مقاومتی و مصرف مکمل‌ کراتین هیدروکلراید در سنین سالمندی باشد.
واژگان کلیدی: تمرین مقاومتی، کراتین هیدروکلراید، مایوژنین، HSP70 و سارکوپنی.

چکیده [English]

Objective: It seems that with increasing age, the speed of contractile proteins and the synthesis of mitochondrial proteins of muscles decreases.The purpose of this study was to investigate the effect of eight weeks of resistance training and creatine-hydrochloride supplementation on myogenin and HSP70 gene expression in the soleus muscle of aged male rats.
Methodology: 32 old male were randomly divided into 4 groups: control, supplement, combined and exercise. Resistance training consisted of eight weeks of ladder training with moderate intensity (70% of MVCC) and five days a week. Rats in the supplement and combined groups received creatine-HCL at the rate of 200 mg/kg of body weight by gavage 5 days a week for 8 weeks. myogenin and HSP70 were obtained using real-time PCR method. Statistical analysis was performed with two-way and Tukey's post hoc test.
Results: The results showed a significant increase in the expression of HSP70 and myogenin gene in the soleus muscle in the combination group compared to the control and supplement groups (p=0.001). No significant difference was observed between the control and supplement groups (p=0.158).
Conclusion: It seems that the increase of HSP70 and the inhibition of muscle apoptosis caused by sarcopenia and the increase of mitochondrial function as well as the increased effect of myogenin on muscle hypertrophy and the creation of an anabolic environment for muscle growth in old age indicate the importance of resistance training and the consumption of protein supplements in old age.
Keywords: Resistance training, creatine-hydrochloride, myogenin, HSP70.
