فعالیت های ورزشی منظم نقش برجسته و مهمی در فرایند سالمندی دارد. هدف از مطالعه‌ی حاضر، بررسی تاثیر هشت هفته تمرین تناوبی بی هوازی بر آیریزین و نیمرخ لیپیدی مردان سالمند بود. در این مطالعه نیمه تجربی 26 نفر از مردان سالمند شهر سمنان (سن66/3±78//63 سال) به طور در دسترس انتخاب و به طور تصادفی به دو گروه کنترل (12=n) و تمرین (14n=) تقسیم شدند. گروه تجربی تمرین تناوبی بی هوازی را با شدت 70 تا 80 درصد حداکثر ضربان قلب، به مدت هشت هفته و شش جلسه در هفته اجرا کردند. از روش الایزا برای اندازه گیری متغیرهای بیوشیمیایی استفاده شد. نتایج نشان داد که هشت هفته تمرین تناوبی بی هوازی، سطح سرمی آیریزین را به طور معنی داری افزایش داد. همچنین سطوح گلوکز و LDL به طور معنی داری کاهش یافت. بر اساس یافته های پژوهش، انجام تمرینات تناوبی بی هوازی ضمن افزایش آیریزین و ایجاد تغییرات مطلوب در نیمرخ لیپیدی، منجر به بهبود ترکیب بدنی افراد سالمند می گردد.

چکیده [English]

Regular physical activities play a prominent role in the aging process. The purpose of this study was to investigate the effect of eight weeks anaerobic interval training on the Irisin, Insulin and lipid profiles in elderly men. In this quasi experimental study 26 elderly men from semnan city (age 63.78±3.66 years old) were selected and randomly divided into two groups of intervention (n=14) and control (n=12). The intervention group performed anaerobic interval training with 10 to 17 repetitions of 20 seconds running, 70-80% maximal heart rate and 80 second recovery. The ELISA method was used to measure biochemical variables and multivariate analysis of covariance used to analyze the data at a significant level of P≤0.05.
Findings: The results showed that 8 weeks of anaerobic interval training significantly increased the level of Irisin (P=0.001). Also, glucose levels (P=0.001) and LDL (P=0.001) decreased significantly. Based on the findings, performing anaerobic interval training, with increased of Irisin and development of lipid profile leads to improves the body composition of the elderly and brings happiness and vitality to this community of people.
