چکیده
زمینه و هدف: فعالیت های ورزشی احتمالاً می توانند بر شاخص های خونی مرتبط با عملکرد اثر بگذارند. پژوهش حاضر با هدف بررسی تاثیر یک جلسه تمرین شبه رقابتی بر شاخص های هماتولوژیک اعضای تیم ملی ایروبیک ژیمناستیک انجام شد. روش تحقیق: در این مطالعه نیمه تجربی 7 نفر از اعضای تیم ملی ایروبیک ژیمناستیک مردان ایران با میانگین سنی 1/72± 22/87 سال، وزن 3/50±68/50 کیلوگرم و قد 4/80± 172/50 سانتی متر، به صورت داوطلبانه شرکت کردند. جلسه تمرینی حدود 32 دقیقه به طول انجامید که شامل: 10 دقیقه گرم کردن عمومی، 1دقیقه و 45 ثانیه انجام حرکات اختصاصی به صورت گروهی همراه با موزیک، 10 دقیقه گرم کردن اختصاصی، 6 دقیقه مرور حرکات، 4 دقیقه استراحت و تمرکز و در پایان برنامه اصلی، مسابقه به مدت 1 دقیقه و 45 ثانیه بود. پیش و بلافاصله پس از تمرینات ویژه، مقدار 10 میلی لیتر خون از ورید بازویی ورزشکاران اخذ گردید. از t همبسته جهت بررسی متغیرهای هماتولوژیکی در مراحل پیش و پس آزمون استفاده شد ( 05/p<0).یافته ها: پس از جلسه تمرین شبه رقابتی ایروبیک ژیمناستیک، تعداد گلبول های سفید خون (01/p=0). درصد پلاکت های خون ( 02/p=0)، و تعداد لنفوسیت ها ( 001/p=0) به طور معنی دار افزایش یافتند؛ اما سایر متغیرهای هماتولوژیک، تغییر معنی داری نکردند ( 05/p>0). نتیجه گیری: با توجه به عدم تغییر عمده شاخص های هماتولوژیک مورد بررسی در پژوهش حاضر، به نظر می رسد اجزاء برنامه فعالیت شبه رقابتی اختلالی در عوامل خونی به واسطه نوع فعالیت ایجاد نمی کند.

چکیده [English]
Background and Aim: Exercise can influence hematological parameters related to performance. The purpose of this study was to determine the acute effect of single session of competition like specific exercise on hematological indices in members of Iranian national aerobic gymnastics team. Materials and Methods: In this semi-experimental study, seven male members of Iranian national aerobic gymnastics team (mean age 22.78 ± 1.72 years; weight, 68.50 ± 3.50kg; height, 172.50 ± 4.07 cm) voluntarily participated. The exercise session was about 32 min consisting of 10 min of general warm-up, 1 min and 45 seconds of specific group exercises with music, 10 min of specific warm-up, 6 min of reviewing the exercises, 4 min of relaxation and meditation, and 1 min and 45 seconds of the main competition at the end. 10 ml blood samples pre and post exercise were taken from arm vena. To examine changes in the hematological variables, dependent t-test was used at PResults: Significant increases were found in platelet percent (p=0.02), blood cell count (p=0.01) and lymphocyte count (p=0.001); while other hematological parameters did not change significantly (p>0.05) after a session of competition like specific exercise. Conclusions: Based on many unchanged hematologic parameters in this study, it seems that details of exercise training program don’t disturb hematological factors induced by exercise mode in aerobic gymnastic athletes.
