چکیده
هدف این پژوهش زمان‌سنجی انواع تصویرسازی ذهنی در شناگران ماهر و غیرماهر بود. این پژوهش از نوع نیمه تجربی با طرح دو گروهی سری‌های زمانی بود. شرکت‌کننده‌ها شامل 30 شناگر مرد بودند که با استفاده از نمونه‌گیری تصادفی ساده انتخاب شدند و خطای آنها در تخمین زمان تصویرسازی شنای کرال سینه 100 متر اندازه‌گیری و با استفاده از تحلیل واریانس عاملی با اندازه‌گیری مکرر در سطح اطمینان 95 درصد تحلیل شد. براساس نتایج، شناگران ماهر در زمان‌بندی تصویرسازی با بیش‌تخمینی و شناگران غیرماهر با کم‌تخمینی روبرو بودند. گروه ماهر در مقایسه با همتایان غیرماهر از دقت تصویرسازی بالاتری برخوردار بودند. هر دو گروه شناگران ماهر و غیرماهر، در استفاده از تصویرسازی بصری درونی و بیرونی زمان مشابهی صرف کردند، اما مدت زمان تصویرسازی حرکتی بالاتر از زمان تصویرسازی بصری بود. براساس یافته‌ها، نیاز به کنترل خطای زمان‌بندی در مداخلات تصویرسازی ذهنی برای بهینه‌سازی اجرای شناگران مورد بحث است.

چکیده [English]
The purpose of this study was the chronometry of mental imagery types among skilled and unskilled swimmers. It was a quasi-experimental with a two-group time-series design. The participants included 30 male swimmers who were selected using simple random sampling. The error in time estimation of 100-meter front crawl imagery was measured. Data were analyzed using factorial repeated measure analysis of variance in 95% confidence level. Results showed that skilled swimmers encountered overestimation in the timing of imagery, whereas unskilled swimmers encountered underestimation. The skilled group compared to unskilled counterparts had higher accuracy in their imagery. Both skilled and unskilled groups spent similar time for internal and external visual imagery, but the duration of kinesthetic imagery was higher than visual imagery. According to the results, the need for controlling of timing error in mental imagery interventions for optimizing of swimmers’ performance remains debated.
