چکیده

مقدمه: مولکول چسبان بین سلولی sICAM-1 به عنوان یکی از شاخص‌های بیماری‌های قلبی-عروقی و آترواسکلروز شناخته شده است. هدف این پژوهش مطالعه‌ی اثر 12 هفته تمرین استقامتی بر مولکول چسبان بین سلولی sICAM-1 (عامل التهاب عروقی) و پروفایل لیپید مردان سالمند بود.روش‌ها: بدین منظور از بین افراد سالمند داوطلب شرکت در این پژوهش، تعداد 24 نفر به طور تصادفی به عنوان نمونه انتخاب شدند و به دو گروه شاهد (12 نفر) و تجربی (12 نفر) تقسیم شدند. برنامه‌ی تمرینی به مدت 12 هفته و هفته‌ای 3 جلسه، با مدت و شدت مشخص (بین 50 تا 75 درصد ضربان قلب حداکثر) اجرا شد. پس از 14 ساعت ناشتا بودن و 24 ساعت پس از آخرین جلسه‌ی تمرین و با شرایط مشابه از هر دو گروه نمونه‌ی خون گرفته شد. برای آنالیز بیوشیمیایی و سنجش مقادیر sICAM-1 از کیت تجاری DiacLone ساخت کشور فرانسه و برای سنجش میزان پروفایل لیپید از کیت‌های آزمایشگاهی شرکت پارس آزمون توسط دستگاه Elisa Reader مدل Hyperion استفاده شد. داده‌های حاصل با استفاده از آزمون‌های kolmogorov-smirnov، Paired-t و Student-t در سطح معنی‌داری 05/0≥α با نرم‌افزار SPSS نسخه‌ی 15 تجزیه و تحلیل شدند.یافته‌ها: نتایج این پژوهش نشان داد، 12 هفته تمرین استقامتی کاهش معنی‌داری در مقادیر sICAM-1 (05/0 >P ) ایجاد کرد. اگر چه در مقادیر پروفایل لیپید مردان سالمند (کلسترول، تری‌گلیسرید، LDL، HDL)) تغییر معنی‌داری دیده نشد (05/0 ≤P ).نتیجه‌گیری: بنابراین، با توجه به کاهش معنی‌دار شاخص التهابی sICAM-1 در مقابل عدم تغییرات معنی‌دار پروفایل لیپیدی در نتیجه‌ی تمرین استقامتی، شاید بتوان sICAM-1 را به عنوان شاخصی حساس‌تر و دقیق‌تر برای پیش‌گویی بیماری‌های قلبی-عروقی معرفی کرد.

چکیده [English]

Background: Soluble intercellular adhesion molecule-1 (sICAM-1) has been identified as a biomarker of cardiovascular diseases and atherosclerosis. The purpose of this study was to examine the effects of 12 weeks of endurance training on sICAM-1, as a cardiovascular inflammation factor, and lipid profiles of elderly men.Methods: Among elderly men who volunteered to participate in this study, 24 persons were randomly selected and divided into two groups of control (n = 12) and intervention (n = 12). Training was performed 3 sessions a week for 12 weeks. The time and intensity (50-75% of maximum heart rate) of exercises were fixed. Blood sampling was conducted after 14 hours of fasting and 24 hours after the last session of training both in similar conditions. The commercial kit of Diaclone (France) was used for biochemical analysis and evaluation of sICAM-1 values. In order to evaluate lipid profiles, an enzyme-linked immunosorbent assay (ELISA) reader (Hyperion, Pars Azmoon Co., Iran) was used. The resulting data was analyzed in SPSS15 using Kolmogorov-Smirnov, paired-t, and student's-t tests at a significance level of α ≤ 0.05.Findings: The results of this study revealed that 12 weeks of endurance training significantly reduced sICAM-1 values (P ≤ 0.05) as a new biomarker for the prediction of cardiovascular accidents. However, no significant reduction (P ≥ 0.05) was observed in lipid profile values (total cholesterol, triglyceride, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol) of elderly men.Conclusion: By noticing significant reductions in inflammatory biomarker of sICAM-1, despite the absence of significant reductions in lipid profile values, caused by endurance training, perhaps sICAM-1 biomarker can be introduced as a more sensitive and accurate marker for the prediction of cardiovascular diseases.
