چکیده
التهاب مزمن با خطر ابتلا به بیماری‌های مختلفی مانند اتروسکلروزیس و دیابت مرتبط است. هدف از تحقیق حاضر بررسی تأثیر هشت هفته تمرین مقاومتی بر تغییرات پروتئین واکنش‌پذیر C و سیستاتین C در مردان ورزشکار بود. به همین منظور 20 آزمودنی از والیبالیست‌های شهرستان سنندج داوطلبانه در تحقیق شرکت کردند و به‌صورت تصادفی در دو گروه مقاومتی فزاینده (10n= ) و کنترل (10n= ) قرار گرفتند. تمرینات مقاومتی فزاینده به‌صورت سه جلسه در هفته و به مدت هشت هفته با شدت 70 درصد یک تکرار بیشینه انجام گرفت و در پایان هفتۀ هشتم به 90 درصد یک تکرار بیشینه رسید. نمونه‌گیری از خون پیش و پس از دورۀ تمرینی برای ارزیابی پروتئین واکنش‌پذیر C و سیستاتین C در پلاسما صورت گرفت. نتایج نشان داد که در تعامل زمان در گروه تفاوت معناداری در سیستاتین C وجود داشت (047/0P=). با وجود این اثر زمان و نیز اثر زمان در گروه در CRP معنادار نبود (05/0P>). نتیجه گرفته می‌شود که هشت هفته تمرین مقاومتی فزاینده می‌تواند موجب کاهش سیستاتین C به‌عنوان یک شاخص التهابی جدید شود. با وجود این چنین پروتکلی تأثیری بر میزان غلظت CRP پایه ندارد.

چکیده [English]
Chronic inflammation is associated with the development of various diseases such as atherosclerosis and diabetes. The aim of this study was to investigate the effect of 8 weeks of resistance training on changes of C reactive protein (CRP) and cystatin C in male volleyball players. For this purpose, 20 volleyball players voluntarily participated in the study and were divided randomly into progressive resistance training (PRT, n=10) and control (Con, n=10) groups. PRT was conducted for 8 weeks, 3 sessions per week with the intensity of 70% maximal repetition (1RM) and reached 90% 1RM by the 8th week. Blood samples were collected before and after PRT to analyze CRP and cystatin C in the plasma. The results showed that in the interaction of time× group, there was a significant difference in cystatin C (P=0.047). However, the effect of time and the effect of time x group were not significant in CRP (P>0.05). It can be concluded that 8 weeks of progressive resistance training reduced cystatin C as a new inflammatory index. However, this protocol had no effects on basal CRP concentration.
