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.
