چکیده

زمینه و هدف: CRP یک شاخص حساس التهاب سیستمیک است که افزایش آن همواره با افزایش خطر بیماری‌های قلبی عروقی همراه است. هدف از این مطالعه مقایسۀ شدت­های مختلف یک جلسه فعالیت ترکیبی بر میزان پروتئین واکنش­گر C است.
روش بررسی: در این تحقیق 10 مرد سالم فعال (4/1±5/21سال) با شاخص تودۀ بدنی طبیعی (2/1±2/22 کیلوگرم بر متر مربع) به طور داوطلب با دارا بودن شرایط لازم شرکت کردند. هریک از شرکت­کنندگان فعالیت ترکیبی (ترکیب فعالیت هوازی و مقاومتی) را در سه شدت: کم، متوسط و زیاد انجام دادند برای مقایسۀ شدت­های مختلف، مرحلۀ هوازی فعالیت به شکل دویدن روی تردمیل با سرعت 8، 6/9 و 2/11 کیلومتر بر ساعت و هزینه مشابه 300 کیلوکالری و مرحلۀ مقاومتی بر اساس 45، 65 و 85 درصد حداکثر قدرت بیشینه در شش حرکت یکسان­سازی شدنمونه­گیری خون قبل، بلافاصله بعد و 24 ساعت بعد از هر جلسه فعالیت انجام شد.
یافته­ها: تجمع لاکتات پلاسما بلافاصله بعد از فعالیت در مقایسه با قبل و 24 ساعت بعد از فعالیت افزایش یافت(05/0P<). فعالیت ترکیبی حاد در شدت­های مختلف به­ طور معناداری به تغییرات در میزان CRP منجر نشد (05/0<P).
نتیجه­گیری: نتایج تحقیق نشان داد که شدت­های مختلف فعالیت ترکیبی بر میزان CRP مردان فعال تأثیر چندانی ندارد که احتمالاً نشان­دهندۀ اهمیت حجم فعالیت نسبت به شدت فعالیت است.
