مقدمه: یکی از بافت‌های که در فرآیند چاقی تاثیرگذار است، بافت چربی می‌باشد. هدف از پژوهش حاضر، تاثیر هشت هفته تمرینات تناوبی شدید بر بیان ژن‌های 12.13.diHome، SREBP-1 و ترکیب بدن رت‌های نرویستارچاق بود.
روش‌کار ؛ پژوهش حاضر، 18 موش صحرایی نژاد ویستارنر چاق با سن هشت هفته و وزن 20/42±88/343 گرم، به صورت تصادفی به دو گروه؛ تناوبی شدید (10سر) و کنترل (8سر) تقسیم شدند. موش‌های گروه‌ تجربی به مدت هشت هفته، هفته‌ای پنج جلسه، تمرینات تناوبی شدید با شدت85 تا 90 درصد حداکثر سرعت را انجام دادند و برای اندازه‌گیری بیان ژن 12.13.diHome و SREBP-1 ازروش Real Time-PCR استفاده شد. از روش آماری تی‌مستقل و تی وابسته جهت بررسی داده‌های آماری در سطح معنی‌داری05/0≤P استفاده شد.
نتایج؛ نتایج پژوهش حاضرنشان داد تمرینات تناوبی شدید منجربه افزایش معنادار بیان ژن 12.13.diHome (001/=P)و کاهش بیان ژن SREBP-1 گردید. همجنین، سبب کاهش وزن (001/0=P) و شاخص توده بدن (001/0=P)رت‌ها شد.
نتیجه‌گیری؛ بنابرنتایج این پژوهش، پیشنهاد می‌شود از تمرینات تناوبی شدید که موجب افزایش لیپولیز درون عضلانی و کاهش لیپوژنز کبدی می‌شود؛ در جهت کاهش توده چربی استفاده شود.

Abstract:
Introduction: Adipose tissue is one of the tissues that affects the process of obesity. The aim of the present study was the effect of eight weeks of high intensity interval training on the expression of 12.13.diHome, SREBP-1 genes and body composition of non-obese rats.
working method; In the present study, 18 obese Wistar rats, aged eight weeks and weighing 343.88±42.20 grams, were randomly divided into two groups; high intensity interval training (10 heads) and control (8 heads). The rats of the experimental group performed high intensity interval training with an intensity of 85 to 90% of the maximum speed for eight weeks, five sessions a week, and Real Time-PCR method was used to measure the expression of 12.13.diHome and SREBP-1 genes. Became. Statistical methods of independent t-test and dependent t-test were used to check the statistical data at a significance level of P ≤ 0.05.
Results; The results of the present study showed that high intensity interval training led to a significant increase in the expression of the 12.13.diHome gene (P=0.01) and a decrease in the expression of the SREBP-1 gene. The same embryo caused a decrease in the weight (P=0.001) and body mass index (P=0.001) of the rats.
conclusion; According to the results of this research, it is suggested to use high intensity interval training that increase intramuscular lipolysis and decrease hepatic lipogenesis; To be used to reduce fat mass
