چکیده

مقدمه و هدف: هدف تحقیق حاضر تعیین آثار30 دقیقه پیش­سرمایش بر شاخص­های عملکرد بی هوازی  مردان فوتسالیست بود.
مواد و روشها: 12 آزمودنی مرد به صورت تصادفی و به روش متقاطع در دو جلسه جداگانه به فاصله 3 روز از جلیقه معمولی و جلیقه یخ استفاده کردند. پروتکل پیش سرمایش شامل سرد کردن بدن به مدت 30 دقیقه با جلیقه یخ بود که آزمودنی­ها پس از آن به گرم کردن پرداخته و سپس آزمون توان بی هوازی RAST را اجرا کردند. متغیر های دما ،لاکتات خون، ضربان قلب ،توان بیشینه ،متوسط و کمینه اندازه گیری شدند. برای مقایسه تغییرات بین گروهی از روش آماری t مستقل استفاده شد.
یافته ها: نتایج تحقیق نشان داد که در گروه پیش­سرمایش، میانگین برون ده توان بیشینه، توان متوسط، توان کمینه، تغییرات ضربان قلب و دمای مرکزی، نسبت به گروه کنترل بالاتر بود و تفاوت معنا­داری در مقایسه با گروه کنترل مشاهده شد (p نتیجه گیری: این نتایج پیشنهاد می­کنند که 30 دقیقه پیش­سرمایش موجب بهبود تکرار اجرای فعالیت شدید از طریق انسداد عروق پوستی که احتمالا موجب افزایش جریان خون به عضلات کاری می شود، می­گردد.

چکیده [English]

Background & Purpose: The purpose of this study was to determine the effects of 30 minutes whole body pre-cooling on anaerobic performance indices in men futsal players.
Material and Methods: 12 male subjects were tested in random order in cross over study after  either 30 minutes of precooling using ice jackets  or under control conditions(no precooling).Tests were separated by minimum of three days. This was immediately followed by RAST anaerobic power test. TET-350 digital thermometer and hp-cosmos lactometer were used to measure core temperature and blood lactate, respectively. T-independent test were also used to compare changes between groups.
Results: Findings showed that maximum, mean and minimum power output, heart rate and core temperature after precooling were significantly higher than the control group (P< 0/05) but, significant differences between the groups were not observed in blood lactate levels (PConclusions: These results suggest that 30 minutes of precooling improve repeated bouts of intensive activity through the occlusion of Skin Vessels to stimulate blood flow to the working muscles.
