چکیده
هدف: تاثیر تمرینات مقاومتی در کنار مکمل های گیاهی بر مسیر پیام رسان mTOR در بافت های غیرعضلانی کمتر بررسی شده است. هدف از تحقیق حاضر ارزیابی تاثیر یک دوره تمرین مقاومتی و مکمل اسپیرولینا بر مسیر ژنی TSC2(RAGs)/mTOR /4E-BPs بافت کلیه موش های صحرایی نر بود. روش: تعداد 32 موش صحرایی 3ماهه و با میانگین وزن 20±150 گرم به طور تصادفی به چهارگروه کنترل، تمرین مقاومتی، مکمل اسپیرولینا و تمرین+مکمل اسپیرولینا تقسیم شدند. گروه های مکمل هرروز 200 میلیگرم اسپیرولینا مصرف می کردند. پروتکل تمرین مقاومتی به مدت هشت هفته، هفته ای 3 روز و یکبار در روز انجام شد. میزان بیان متغییرهای وابسته تحقیق با روش Real Time_PCR اندازه گیری و با تحلیل واریانس دوراهه مورد تجزیه قرار گرفتند. یافته‌ها: افزایش معناداری در میزان بیان ژن 4E_PBs در گروه تعاملی مکمل اسپیرولینا و تمرین مشاهده شد (012/0 P=)، ژن TSC2 در هیچ کدام از گروهها نسبت به گروه کنترل افزایش معناداری نداشت. در فاکتور RAGs افزایش معناداری در هر سه گروه مکمل اسپیرولینا (001/0 P=)،گروه تمرین مقاومتی (001/0 P=) و گروه تعامل تمرین مقاومتی و مکمل (001/0 P=) مشاهده شد. همچنین افزایش معناداری در میزان بیان ژن mTOR در گروه مکمل اسپیرولینا (001/0 P=) و گروه تمرین مقاومتی (014/0 P=) مشاهده شد. نتیجه گیری: با توجه به اینکه که در گروه تعامل تمرین مقاومتی با مصرف مکمل اسپیرولینا افزایش معناداری در بیان ژن mTOR مشاهده نشد و همچنین به دلیل نقش بافت کلیه در عملکرد فیزیولوژیکی بدن، انجام تحقیقات بیشتر در این زمینه امری ضروری بنظر می‌رسد
