چکیده

مقدمه و اهداف
افراد سالمند اغلب تحت تاثیر شرایط التهاب خفیف قرار دارند که می­تواند با افزایش سطوح سایتوکین­ها و پروتئین­های مرحله حاد در این دوران همراه باشد. با این حال نتایج تحقیقات حاکی از آن است که شیوه­های مختلف تمرینات ورزشی منظم می­تواند اثرات مفیدی بر غلظت شاخص­های التهابی داشته باشد. لذا پژوهش حاضر با هدف بررسی تاثیر تمرینات ورزشی موازی بر غلظت پروتئین واکنشگر-C (CRP) و فیبرینوژن پلاسما در مردان سالمند صورت پذیرفت.
مواد و روش­ها
24 مرد سالمند که به­صورت داوطلبانه در پژوهش حاضر شرکت کردند در دو گروه همگن شده­ی تمرین و کنترل قرار گرفتند. افراد گروه تمرین 14 هفته به انجام تمرینات ورزشی ترکیبی پرداختند. سپس قبل از شروع تمرینات و 72-48 ساعت بعد از آخرین جلسه تمرینی، نمونه­های خون وریدی جهت اندازه­گیری CRP و فیبرینوژن جمع­آوری شد. همچنین در هر دو مرحله شاخص­های پیکرسنجی و ترکیب بدنی مورد اندازه­گیری قرار گرفت. داده­ها با استفاده از آزمون­های آماری آنالیز واریانس با اندازه­گیری­های مکرر و ضرب همبستگی پیرسون مورد تجزیه و تحلیل قرار گرفت.
یافته­ ها
بعد از انجام 14 هفته تمرینات موازی، کاهش معناداری در غلظت CRP و فیبرینوژن در گروه تمرین در مقایسه با گروه کنترل مشاهده شد (05/0P<). میانگین شاخص­های ترکیب بدنی وزن، درصد چربی بدن، محیط کمر، شاخص توده بدنی پس از 14 هفته اجرای تمرینات موازی در گروه تمرین کرده به­طور معناداری کاهش پیدا کرد (05/0‌>P)، در حالی­که این شاخص­ها در گروه کنترل بدون تغییر باقی ماند (05/0‌<P). به­علاوه رابطه معناداری بین تغییرات شاخص­های CRP و فیبرینوژن با تغییرات درصد چربی بدن و و دیگر شاخص­های ترکیب بدن مشاهده شد (05/0‌>P).
نتیجه­ گیری
بر اساس یافته­های حاصل از پژوهش می­توان اظهار داشت که انجام تمرینات ورزشی موازی می­تواند روش تمرینی مناسبی برای بهبود ترکیب بدن و تعدیل شاخص­های التهابی پیش­بینی کننده بیماری­های قلبی-عروقی در مردان سالمند باشد.

چکیده [English]

Background and Aim: Older persons are often affected by a low-grade proinflammatory state characterized by increased levels of cytokines and acute phase proteins. Previous studies indicate that different methods of exercise training have beneficial effects on the cytokine concentration. Hence, the present study was conducted to evaluate the effects of concurrent training on C-reactive protein (CRP) and fibrinogen levels in elderly men.
Materials and Methods: A total of 24 elderly men who volunteered to participate in the study were equally assigned to training and control groups. Participants in the training group performed 14 weeks of concurrent training. Then, at the beginning of the study and at 48–72 h after the last training session, blood samples were collected to measure CRP and fibrinogen levels. Moreover, at both times, body composition and anthropometric indices were measured. Data were analyzed using repeated measures analysis of variance and Pearson's correlation coefficient tests.
Results: After 14 weeks of concurrent training, the CRP and fibrinogen levels were significantly lower in the training group compared with those of the control group (P<0.05). Concurrent training significantly decreased body weight, body fat percent, body mass index, and waist-to-height ratio in the training group (P<0.05), while these parameters remained unchanged in the control group (P>0.05). Moreover, a significant correlation was observed between the mean changes in CRP and fibrinogen levels and the body fat percent and other body composition indices (P<0.05).
Conclusion: The results of the current study indicated that concurrent exercise training is a suitable method for improving body composition and modulating the levels of cytokines predictive of cardiovascular disease in elderly men.
