چکیده
زمینه و هدف: رابطه معکوسی بین میزان فعالیت بدنی و نشانگرهای زیستی التهابی وجود دارد؛ بنابراین هدف از پژوهش حاضر، بررسی تأثیر 6 هفته تمرین تناوبی با شدت بالا بر سرعت رسوب گلبولهای قرمز خون مردان جوان غیر فعال است. روش تحقیق: به این منظور، 18 مرد جوان غیر فعال (میانگین سن: 71/1±80/23 سال، قد: 89/5±22/178 سانتیمتر و وزن: 91/6±27/74 کیلوگرم) بهصورت داوطلبانه در پژوهش شرکت کردند و به طور تصادفی به دو گروه تجربی و کنترل تقسیم گردیدند. آزمودنیهای گروه تمرین به مدت 6 هفته و هر هفته 3 جلسه تمرین تناوبی با شدت بالا (بالای 90 درصد حداکثر ضربان قلب) را اجرا کردند. از همه آزمودنیها قبل و بعد از 6 هفته تمرین تناوبی با شدت بالا در حالت ناشتا خونگیری به عمل آمد. سرعت رسوب گلبول های قرمز با روش وسترگرن و میزان هماتوکریت، تعداد سلولهای قرمز و هموگلوبین به روش فلوسیتومتری اندازه گیری شدند. جهت تجزیه و تحلیل دادهها از آزمونهای آماری t مستقل و t همبسته در سطح 05/0>p استفاده گردید. یافته‌ها: یافته های پژوهش حاضر نشان داد که 6 هفته تمرین تناوبی با شدت بالا منجر به کاهش معنی دار سرعت رسوب گلبولهای قرمز (004/0=p)، درصد چربی (01/0=p)، هماتوکریت پلاسما (002/0=p)، تعداد سلولهای قرمز پلاسما (001/0=p)، هموگلوبین پلاسما (001/0=p) و افزایش حجم پلاسما (001/0=p) در گروه تمرین نسبت به گروه کنترل شد. نتیجه گیری: احتمالاً تمرین تناوبی با شدت بالا، یک عامل کارآمد برای بهبود متغیرهای خونی مرتبط با عوامل خطرزای بیماری های قلبی ـ عروقی در مردان غیر فعال است.

چکیده [English]
Background and Aim: There is inverse relationship between physical activity and inflammatory biomarkers; so the aim of this study was to investigate the effect of a high intensity interval training course on erythrocyte sedimentation rate of sedentary young men. Materials and Methods: For this purpose, 18 sedentary male (age=23.80±1.71 years, height=178.22±5.89 cm, weight=74.27±6.91kg) were voluntarily chosen and randomly divided into training and control groups. The training group performed high intensity interval training (high 90 percent) for 6 weeks and 3 sessions per week. The hematocrit, hemoglobin and red blood cells and erythrocyte sedimentation rate were measured by flow cytometry and Westergren method respectively, before and after 6 weeks of high intensity interval training from all subjects, in the fasting state. The dependent t-test and independent t- test were used to analyze the data of study at p< 0.05. Results: The results of this study showed that six-weeks of high intensity interval training reduce the significantly erythrocyte sedimentation rate (p=0.004), body fat (p=0.01), plasma hematocrit (p= 0.002), plasma hemoglobin (p=0.001) and plasma red blood cell count (p = 0.001) and increase the volume of plasma in the training group. Conclusion: The results suggest that the high intensity interval training could be considered as a important factor to improve blood variables associated with the reduction of risk of cardiovascular disease in sedentary young men.
