چکیده

هدف: استرس روانی ناشی ازمسابقه با ایجاد تغییراتی در سیستم ایمنی، استعداد بروز بیماریهای عفونی در ورزشکاران را بیش
از فعالیت های ورزشی معمول افزایش میدهد؛ بنابراین مطالعه حاضر باهدف بررسی اثر مسابقه رسمی بر تعداد لکوسیت ها،
و کورتیزول سرمی در کاراته کاران جوان اجرا شد. )IgG( G ،)IgA( A زیرگروه های آن، غلظت ایمونوگلوبولین های

و کورتیزول IgG ،IgA مسابقه، جهت اندازه گیری شمار لکوسیت ها، نوتروفیل ها، لنفوسیت ها، منوسیت ها و ائوزینوفیل ها و نیز غلظت

به طور معنی دار کاهش یافت. )P= 0/ و بلافاصله پس از مسابقه ) 001 )P=0 / پس ازآن، نسبت به قبل از شروع مسابقه ) 003
نتیجه گیری: بر اساس نتایج این مطالعه، مسابقه رسمی موجب سرکوب موقت دستگاه ایمنی هومورال کاراته کاران جوان می شود.
همچنین، دوره دوساعته استراحت پس از مسابقه برای بازیافت تغییرات ایجادشده در شمار لکوسیت ها، زیرگروه های آن و غلظت
ایمونوگلوبولین های سرمی کافی به نظر می رسد.

چکیده [English]

Purpose: Psychological stresses induced by competition, can cause immune system alternations, which predisposes the athletes to infectious diseases more than common exercises. Therefore, the purpose of this study was to examine the effects of official sports competition on leucocyte, and subsets counts, immunoglobulin A (IgA), G (IgG), and cortisol levels in male karatekas.
Methods: Ten male karatekas (aged: 22.9±2.6 yr, height 176.4±8.3 cm, and body mass index 21.2±1.5 kg/m2), acceded to final competition of Ilam province, were selected. Blood samples were collected before, immediately and 2 hours after the competition to measure the number of leukocytes, neutrophils, lymphocytes, monocytes, eosinophil’s counts and IgA, IgG and cortisol levels.
Results: The leucocyte (P=0.001), lymphocyte (P=0.001), and monocyte (P=0.003) counts were significantly increased immediately after the competition but returned to baseline 2h after the competition. Neutrophil and eosinophil counts did not change immediately and 2h after the competition (P>0.05). The serum levels of IgA (P=0.037) and IgG (P=0.04) were decreased significantly immediately after the competition and returned to baseline 2h after the competition. Also, the serum cortisol level was increased significantly immediately after the competition (P=0.0001) but decreased 2h later, compared to before (P=0.01) and immediately (P=0.001) after the competition results.
Conclusion: Based on the findings of the present study, official competition can cause transient depression on humoral immunity in young male karatekas. It seems that 2h rest after the competition is sufficient for the recovery of leucocyte subset counts and immunoglobulin changing induced by competitions.
