چکیده

اهدف: خون به عنوان حامل اکسیژن، دی اکسید کربن و دیگر مواد مورد نیاز بافت ­ها بسیار مهم است. هماتولوژی ورزشی یک شاخه جدید از فیزیولوژی ورزش است، که سابقه آن در جهان بیش از 30 سال نمی­ باشد .فعالیت های ورزشی احتمالاً می‌توانند بر شاخص‌های خونی مرتبط با عملکرد اثر بگذارند. هدف از پژوهش حاضر بررسی تاثیر شش هفته تمرین مقاومتی با ترتیب حرکتی متفاومت بر تغییرات هماتولوژیک (شامل هموگلوبین، هماتوکریت، تعداد گلبول‎های قرمز، تعداد گلبول‎های سفید، میانگین حجم گویچه‌ای، میانگین هموگلوبین گویچه‌ای، میانگین غلظت هموگلوبین گویچه‌ای، پهنای توزیع گلبول قرمز، تعداد پلاکت و حجم متوسط پلاکتی) در دختران دارای اضافه وزن (شاخص توده بدن بین 30-25 کیلوگرم بر متر مربع) بود.مواد و روش ها: 31 دانشجوی دارای اضافه وزن انتخاب و به طور تصادفی در سه گروه: تجربی 1 (شروع حرکات از عضلات بزرگ به عضلات کوچک،10 نفر)،تجربی 2 (شروع حرکات از عضلات کوچک به عضلات بزرگ، 11نفر) و کنترل (بدون هیچ برنامه تمرینی،10 نفر) قرار گرفتند. برنامه تمرین مقاومتی شامل 6 هفته (3 جلسه در هفته) بود. متغیرهای هماتولوژیک قبل و پس از دوره­ی تمرینی در شرایط استراحتی اندازه‌گیری شدند.یافته ها: یافته‌های تحقیق با استفاده از آزمون تحلیل واریانس یک طرفه نشان داد، متغیرهای هماتولوژیک مورد بررسی در تحقیق حاضر، بین سه گروه تفاوت معناداری نداشتند.نتیجه­ گیری: در کل یافته‌های حاضر نشان داد اجرای برنامه میان مدت تمرین مقاومتی و همچنین تغییر در شیوه اجرای حرکات مقاومتی- هیچ کدام- تاثیری بر پاسخ های هماتولوژیک ندارند.

Effect of six weeks resistance training with different exercise order on hematological variables in overweight women

چکیده [English]

Abstract
Aims: blood is particularly important as it carries oxygen, carbon dioxide, and other substances required by tissues. Sport hematology is a new branch in the field of exercise physiology with a history of not more than 30 years in the world. Exercise can influence hematological parameters related to performance. The purpose of present study was to investigate the effects of resistance training with different resistance order on hematological changes (include HGB, HCT, RBC, WBC, MCV, MCH, MCHC, RDW, PLT and MPV) in overweight women (BMI= 25-30 Kg/m2).
Methods: 31 overweight students were objectively selected and then randomly were divided into three groups: The experimental group 1 (exercises from large to small muscles, n= 10), the experimental group 2 (exercises from small to large muscle, n= 11) and the control group (without any training program, n= 10). Resistance training consists of 6 weeks (3 sessions per week). The Hematological variables were measured in resting conditions before experiment and again after completion of the training period.
Results: Findings with the use of one-way ANOVA revealed there were no significant differences in any of the hematologic variables levels between three groups.
Conclusion: In general, the present findings indicated that medium-term resistance training program and so changing the sequence of performance of resistance exercise – none of them – do not have any effect on hematologic responses.
