چکیده

زمینه و هدف: عموماً اعتقاد بر این است که سردکردن فعال برای ارتقای ریکاوری پس از ورزش مؤثرتر از سردکردن غیرفعال بدون ‏فعالیت است. با این حال، تحقیق در مورد این موضوع هرگز ترکیب نشده است که آیا این باور درست است یا خیر. این بررسی تاثیر حاد ‏سردکردن فعال و غیرفعال بعد از ورزش بر تغییرات فشارخون و ضربان قلب بازیکنان نوجوان پسر بسکتبالیست مقایسه کرد.‏

روش‌ها: پژوهش حاضر بر تعداد 20 پسر نوجوان بسکتبالیست بین سنین 12 تا 14 سال از آکادمی بسکتبال مهر اراک بود که به ‏صورت داوطلبانه و سپس به طور تصادفی در دو گروه برابر 10 نفری تقسیم بندی شدند. داده‌های پایه شامل قد، وزن، شاخص توده بدن ‏و میزان ضربان قلب و فشارخون افراد در مرحله پیش‌آزمون و پس‌آزمون اندازه‌گیری شد. گروه اول آزمودنی ها با روش سردکردن فعال ‏‏(ایستا) و گروه دوم با یک سردکردن غیرفعال شامل نشستن، دراز کشیدن یا ایستادن (بدون راه رفتن) 1 ساعت پس از تمرین مورد ‏ارزیابی قرار گرفتند. جهت تجزیه و تحلیل داده ها از آزمون کولموگروف اسمیرنوف و از آزمون تی دو نمونه مستقل جهت بررسی ‏معناداری تفاوت بین گروه‌ها استفاده شد.‏

یافته ها: نتایج، احتمال بی تاثیر بودن سردکردن بر فشارخون و ضربان قلب بسکتبالیست های پسر نوجوان را نشان داد.‏

نتیجه گیری: بر اساس شواهد تجربی موجود ، سردکردن فعال تا حد زیادی برای بهبود بیشتر فشارخون و ضربان قلب پس از ورزش بی ‏اثر است، اما با این وجود ممکن است در مقایسه با سرد کردن غیرفعال فوایدی را ارائه دهد.‏

چکیده [English]

Background and Objective: Active cool-down is generally believed to be more focused than passive cool-down ‎without activity for promoting post-exercise recovery. However, research has never been done to see ‎if this belief is true. This study compared the acute effect of active and passive cool-down after ‎exercise on blood pressure and heart rate of teenage boy basketball players.‎

Methods: The current research was on the number of 20 teenage basketball players between the ‎ages of 12 and 14 from Mehr Arak Basketball Academy, who were voluntarily and then randomly ‎divided into two groups of 10 people. Basic data including height, weight, body mass index, heart rate ‎and blood pressure were measured in the pre-test and post-test stages. The first group of subjects ‎was evaluated with an active (static) cool-down method and the second group with a passive cool-‎down including sitting, lying or standing (without walking) 1 hour after exercise. To analyze the data, ‎the Kolmogorov-Smirnov test and the t-test of two independent samples were used to check the ‎significance of the difference between the groups.‎

Finding: The results showed the possibility that cool-down has no effect on the blood pressure and ‎heart rate of teenage boy basketball players.‎

Conclusion: Based on the available empirical evidence, active cool-down is largely ineffective for ‎further improvement in blood pressure and heart rate after exercise, but may nevertheless provide ‎benefits compared with passive cool-down.‎
