چکیده
هدف از پژوهش حاضر بررسی تأثیر روشهای معرفی روتین، تصویرسازی و ترکیبی بر اجرا و بازنمایی ذهنی سرویس موجی والیبال بود. بدین‌منظور، 40 دختر به‌صورت تصادفی به چهار گروه معرفی روتین، تصویرسازی، ترکیبی و کنترل تقسیم شدند. پس از پیش‌آزمون، شرکت‌کنندگان بر‌اساس گروه‌بندی مربوطه، تکلیف را به‌مدت هفت روز (هر روز پنج بلوک 10 کوششی) تمرین نمودند. یک هفته پس از آخرین روز تمرین، شرکت‌کنندگان پس‌آزمون را انجام دادند. نتایج نشان می‌دهد که گروه ترکیبی نسبت به دو گروه تجربی دیگر عملکرد بهتری داشته است. گروه معرفی روتین نیز نسبت به گروه تصویرسازی عملکرد بهتری را نشان می‌دهد. با‌این‌حال، در متغیر بازنمایی ذهنی، گروه تصویرسازی نسبت به دو گروه دیگر بازنمایی ساختاریافته‌تری داشته است. علاوه‌‌بر‌این، گروه ترکیبی نسبت به گروه معرفی روتین از بازنمایی ساختاریافته‌تری برخوردار می‌باشد. این نتایج با توجه به مکانیزم‌های زیربنایی این روشهای تمرینی مورد بحث قرار گرفته است.

چکیده [English]
The purpose of this study was to investigate the effect of routine introduction, imagery and mixed methods on performance and mental representation of volleyball overhand float-serve. To this purpose, 40 girls were randomly divided into routine introduction, imagery, mixed and control groups. After a pre- test, participants practiced the task for seven consecutive days (each day 5 blocks 10 trials each) according to their grouping. One week after the last practice session, participants performed the post- test. Results showed that mixed group performed better than two other experimental groups. Also, routine introduction group outperformed than imagery group. However, in mental representation measure, the imagery group had a more structured mental representation than two other groups. In addition, the mixed group had a more structured mental representation than routine introduction group. These results were discussed in relation to the underlying mechanisms of these methods of practice.
