چکیده

مقدمه: فعالیت نیروهای آتش نشان در محیط های سخت و فشار آفرین موجب کاهش تضعیف دستگاه ایمنی از طریق افزایش هورمونهای استرسی و سایتوکاین های التهابی میشود. هدف تحقیق حاضر بررسی تاثیر دو شیوه تمرین مهارتی – عملیاتی و ترکیبی بر شاخص های سیستم ایمنی در مردان آتش نشان بود. مواد و روش ها : 36 آتش نشان مرد (با میانگین سن 56/3±3/38 سال، وزن 63/5±10/81 کیلوگرم و سابقه کاری 35/4±66/13 سال) داوطلب شدند و به صورت تصادفی در سه گروه مهارتی- عملیاتی(12 نفر)، ترکیبی(12 نفر) وکنترل (12 نفر) قرار گرفتند. گروه مهارتی- عملیاتی به مدت هشت هفته (سه جلسه در هفته) در یک برنامه تمرینی مهارتی- عملیاتی شرکت کردند. این برنامه شامل شش مهارت شغلی صعود از برج، حمل وسایل و تجهیزات، حمل مصدوم، حمل و گسترش نردبان، ورود اجباری (ضربان پتک)و حمل و کشیدن لوله آب بود. برنامه تمرین ترکیبی شامل 15دقیقه دویدن هوازی با شدت 60 تا 70 درصد حداکثر ضربان قلب و پنج تمرین قدرتی منتخب بالا تنه و پایین تنه درنظرکرفته شد. قبل از شروع دوره تمرینی و 48 ساعت پس از آخرین جلسه تمرین برای تعیین شاخص های IL6 , CD40 و کورتیزول از تمام آزمودنی ها در حالت ناشتایی خونگیری به عمل آمد. داده ها با استفاده از روش آماری Tزوجی و آنالیز واریانس در سطح معنی دار ی 05/0 P

چکیده [English]

Introduction:. The purpose of this study was to investigate the comparison of the effectiveness of two methods of operational-skills and combined exercises training of immunity systems in male firefighters. Materials and methods: 36 men firefighters were selected voluntarily. The participants of first experimental group were participated in one program of operational-skills training about eight weeks. This program was consisted of stair climb, equipment carry, victim rescue, ladder heel and raise, forcible entry, and hose drag. The treatment of the combined training program was included 15 minutes of aerobic running with 60 to 70 percent of maximum heart rate and five selected strength training for upper and lower parts of the body. Blood test was obtained with all the samples in fasted stated to determine the parameters of IL6, CD40 and cortisol before starting the training period and 48 hours after the last training sessions. The collected data were analyzed according to paired-samples t and analysis of variance with the significant level of P< 0.05. Results: The collected data revealed that the level of cortisol and serum IL6 were decreased significantly in two experimental groups in comparison with the control group. But the level of soluble CD40 had significantly differences in the first experimental group in contrast with the other groups, and there were no differences between two other groups. Conclusions: the results of this study suggested that, it is better the male firefighters use operational- skills training to strengthen the immune system and reduce risk factors in cardiovascular disease
