چکیده

هدف از پژوهش حاضر، مقایسه­ی آثار تمرینات هوازی و ترکیبی بر پاسخ آندوتلیالی در مردان سالمند می­باشد. برای این منظور تعداد 21 نفر مرد سالمند داوطلب سالم غیرورزشکار در محدوده­ی سنی 80-60 سال انتخاب و به صورت تصادفی به 3 گروه تجربی تمرینات هوازی، تمرینات ترکیبی و گروه کنترل تقسیم­بندی شدند. برنامه تمرینی هوازی شامل راه رفتن یا دویدن با شدت 60-50% حداکثر ضربان قلب بیشینه به مدت 45 دقیقه، هفته­ای 3 جلسه بود. آزمودنی­ها در گروه دوم پس از اجرای 22 دقیقه تمرینات مقاومتی با وزنه، سه دوره با 12-10 تکرار در هر جلسه و با شدت 60-40% یک تکرار بیشینه و زمان استراحت 90-60 ثانیه و 22 دقیقه تمرینات هوازی، با شدت 60-50% حداکثر ضربان قلب بیشینه شرکت نمودند. گروه کنترل تا پایان پژوهش مداخله­ای دریافت نکردند. خون­گیری در آغاز و پایان 48 ساعت پس از اتمام تمرینات در شرایط تجربی اجرا شد. یافته‌‌های این پژوهش نشان داد که سطوح ICAM-1 در گروه هوازی (9/39%، 02/0=P) و ترکیبی (68/45%،02/0=P) با کاهش معنی‌دار همراه بوده، اما اختلاف بین گروه­ها معنی‌دار نمی­باشد ) (05/0P>). مقادیر وزن، درصد چربی و شاخص توده­ی بدنی، سطوح TC و TG در دو گروه تجربی کاهش معنی‌داری یافته است (05/0P<). در نهایت تمرینات هوازی و ترکیبی با کاهش در sICAM-1 سرم همراه است. اگر چه این کاهش، در نتیجه­ی تمرینات ترکیبی ممکن است بیش از تمرینات هوازی به تنهایی باشد.

چکیده [English]

The aim of this study was the comparison of the effect of aerobic and combines training of endothelial response on elderly men. Twenty one healthy inactive elderly men (60-80 years old) voluntary selected and randomly allocated in three groups. Aerobic training program (running 3 d/w, 50-60% HRmax, 45 min) and combine training (resistive: 3 d/w, 40-60% 1RM, 10-12 R aerobic 50-60% HRmax, 22 min) were performed for 10 weeks. Fasting blood sample were taken before and at the end of study. Data analysis showed that ICAM-1 level in aerobic training (39.9%, P=0.02) and combine training (45.68%, P=0.02) were significantly decrease, but the difference between gropes weren’t significant (P>0.05). The weight, BF%, BMI, TC and TG levels in experimental gropes were significantly decrease (P<0.05). Finally, aerobic and combine training by mediating serum ICAM-1, although the decline of ICAM-1 levels maybe occurs higher than aerobic training.
