Abstract:
هدف از تحقیق حاضر مقایسه اثر تمرین با تداخل بالا، پایین و فزاینده بر دقت و ساختار بازنمایی ذهنی پرتاب آزاد بسکتبال بود. به این منظور 30 شرکتکننده مبتدی به صورت تصادفی به سه گروه تصادفی، مسدود و افزایشی تقسیم شدند. شرکتکنندگان بر اساس گروه بندی و ترتیب تمرین مشخص شده به مدت سه روز هر روز سه بلوک و هر بلوک شامل 30 کوشش-پرتاب آزاد بسکتبال را از فواصل مختلف (96/3، 57/4، و 18/5 متر) تمرین کردند. سه روز بعد از آخرین جلسه تمرین آزمون های یادداری و انتقال اجرا شد. نتایج نشان داد گروه افزایشی نسبت به دو گروه دیگر دقت بالاتری در یادداری داشت. این اثر برای مرحله انتقال نیز مشابه بود. نتایج متغیر بازنمایی ذهنی نشان داد گروه افزایشی نسبت به دو گروه دیگر بازنمایی ذهنی ساختاریافته تری دارد و این بازنمایی بیشتر با بازنمایی ذهنی شرکتکنندگان ماهر مشابه بود. این نتایج با توجه به پردازش بهتر اطلاعات و همچنین چارچوب نقطه چالش تفسیر شدند.
This study was aimed to compare the effect of practice with high, low, and increasing interference on accuracy and mental representation of basketball free throw. For this purpose, 30 novice participants were randomly divided into random, blocked, and increasing groups. The participants practiced the basketball free throw from different distances (3/96, 4/57, and 5.18 meter) for three consecutive days-three blocks each day and each block included 30 trials- according to the given grouping and practice order. Three days after the last training session retention and transfer tests were performed. Results showed that the increasing group had higher accuracy than the other two groups. The results during the transfer test were similar to the retention test. The results for the mental representation measure showed that the increasing group had a more structured mental representation that two other groups and this mental representation were more similar to the mental representation of the skilled participants. These results were interpreted according to the efficient processing of the information and also according to the challenge point framework

همراستا با این یافتهها نشان داده شده است در تکلیفی مانند ضربه گلف که تداخل در سطح پارامتر ایجاد شده بود، تمرین تصادفی نسبت به تمرین مسدود علاوه بر عملکرد بهتر در آزمون یادداری منجر به بازنمایی ذهنی ساختار یافتهتری نیز میشود (فاضلی و همکاران، 2017).
The population of the present study included Iranian elite male and female athletes (participation in premier leagues and membership in national teams) in various sports who had experience of living in home quarantine in the last 60 days.
The results of the present study showed that home quarantine had different positive and negative psychological effects on Iranian elite athletes due to the prevalence of Quaid-19 disease.
