چکیده
هدف از پژوهش حاضر، مقایسۀ عملکرد پیش‌بینی با شرایط انسداد زمانی تکواندوکاران نخبه و غیرنخبه بود. جامعۀ آماری پژوهش را کلیۀ تکواندوکاران مرد بزرگسال در سال (1394) تشکیل دادند که از میان آن‌ها 20 نفر انتخاب شدند. از فرم ثبت داده‌ها و خطاها، نرم‌افزار شنیداری ـ دیداری ادوب پریمیر و نرم‌افزار مخزن تصاویر به‌عنوان ابزار استفاده گردید. تصاویر با انسداد زمانی مشخص (050/0، 100/0 و 150/0 ثانیه) جهت تشخیص و پاسخ به آزمودنی‌ها ارائه شد. یافته‌ها نشان‌‌دهندۀ تفاوت معنادار در میانگین پیش‌بینی تکواندوکاران نخبه و غیرنخبه در شرایط انسداد می‌باشد. همچنین، پیش‌بینی در (050/0) ثانیه قبل از ضربه، بهترین زمان جهت تشخیص نوع ضربه است. می‌توان گفت که با افزایش زمان پیش از ضربه از (050/0) ثانیه به (150/0) هزارم ثانیه، خطای پیش‌بینی تکواندوکاران غیرنخبه به‌طور معناداری بیشتر از تکواندوکاران نخبه می‌شود.

چکیده [English]
The purpose of this study was to compare the performance of prediction with conditions of time occlusion in elite and non-elite taekwondo players. The population of this study were all adult male taekwondo players in 2015 that 20 taekwondo players were selected. The errors and data record form, Adobe Premiere audio-visual software, and the repository software for images were used as the instrument. The images with specified time occlusion (0.050, 0.100, and 0.150 seconds) were presented to subjects to detect and to respond. The results showed a significant difference between elite and non-elite taekwondo players’ prediction mean in time occlusion. The prediction in 0.050 seconds before the hit was the best time to identify the type of hit. Non-elite taekwondo players’ error of prediction was significantly more than elite taekwondo players with the increasing of time of before the hit from 0.050 seconds to 0.150 thousandth of a second.
