چکیده
افت گرم‌کردن، کاهشی زودگذر در اجرا است که به‌دنبال یک دوره استراحت کوتاه به‌وجود می‌آید. جهت انجام پژوهش حاضر، 60 آزمودنی به‌صورت تصادفی در شش گروه تصویرسازی و نوع مهارت (شامل درونی ـ بسته، بیرونی ـ بسته، کنترل ـ بسته، درونی ـ باز، بیرونی ـ باز و کنترل ـ باز) قرار گرفتند و به‌مدت 15 دقیقه به اجرای تکلیف پرداختند و امتیاز10 اجرای پایانی آن‌ها ثبت شد. در زمان استراحت، گروه‌ها به تصویرسازی درونی یا بیرونی پرداختند و درادامه، پنج کوشش دیگر را انجام دادند. نتایج نشان می‌دهد که در هر دو مهارت باز و بسته، بین گروه‌های تصویرسازی و کنترل تفاوت معناداری وجود دارد. همچنین، در تصویرسازی بیرونی بین گروه‌های باز و بسته (در استراحت پنج دقیقه‌ای) تفاوت معناداری به نفع گروه مهارت باز مشاهده می‌شود. براساس نتایج می‌توان گفت که تصویرسازی، روش مناسبی برای کاهش افت گرم‌کردن بوده و پیشنهاد می‌شود که به‌ویژه برای مهارت‌های حرکتی باز از تصویرسازی بیرونی استفاده گردد.

چکیده [English]
The warm-up decrement is a temporary drop in performance that is followed by a short period of rest. 60 subjects were randomly divided into six groups of imagery and skill types including: internal-closed, external-closed, control-closed, internal-open, external-open and control-open. Each group performed their tasks for 15 minutes and their points for ten final trials were recorded. During the rest period, the subjects performed internal and external imagery followed by five other trials. The results showed that there was a significant difference between the imagery and control groups in both open and closed skills. In the external imagery between open and closed groups (at a five-minute rest), there was a significant difference in favor of the open skill group. Based on the results, the imagery is an appropriate method for the improvement in warm-up decrement and it is recommended to use external imagery especially for open motor skills.
