چکیده

هدف از پژوهش حاضر، بررسی تأثیر ترکیب روش‌های تمرینی مشاهدة عمل، تصویرسازی حرکتی و تمرین جسمانی بر استواری حرکات درون‌مرحله و برون‌مرحله بود. نمونة آماری پژوهش حاضر را 64 دانشجوی دختر رشتۀ تربیت بدنی با دامنة سنی 28ـ20 سال تشکیل دادند که به­صورت تصادفی به چهار گروه 16 نفری (گروه تمرین جسمانی، گروه تمرین جسمانی ـ مشاهدۀ عمل، گروه تمرین جسمانی ـ تصویرسازی حرکتی و گروه مشاهدۀ عمل ـ تصویرسازی حرکتی) تقسیم شدند. پروتکل اجرای پژوهش شامل: سه مرحلۀ پیش از تمرین (پیش­آزمون)، مرحلۀ تمرین و مرحلۀ آزمون (پس­آزمون) بود. در این پژوهش، الگوی درون­مرحله ترکیبی از چرخش داخلی و خارجی ساق پای راست و چپ به­­طور هم­زمان بود، به­صورتی که هر دو پا روی سطح افقی و حول محور عمودی بدن، هم­زمان به سمت داخل و خارج بدن (نسبت به مرکز بدن) حرکت می­کردند. الگوی هماهنگی برون­مرحله نیز شامل حرکت دورانی هر­یک از پاها روی سطح سهمی و حول محور عرضی­ بود. به­منظور تحلیل داده­ها از آزمون تحلیل واریانس یک­راهه و آزمون تعقیبی بونفرونی در سطح P<0.05 استفاده شد.­ نتایج نشان می­دهد که روش ترکیبی مشاهدة عمل ـ تمرین جسمانی در هر دو حرکات درون­مرحله و برون­مرحله، دارای عملکرد بهتر و معناداری نسبت به گروههای دیگر می­باشد (P<0.001). همچنین، گروه ترکیبی تمرین جسمانی ـ تصویرسازی حرکتی نیز عملکرد بهتر و معناداری نسبت به گروههای تمرین جسمانی و مشاهدة عمل ـتصویرسازی حرکتی دارد (P<0.05). براساس نتایج پژوهش حاضر به مربیان پیشنهاد می­شود جهت یادگیری این نوع مهارت­های حرکتی و صرفه­جویی در وقت و هزینه، از روش ترکیبی تمرین جسمانی ـ مشاهدة عمل بهره گیرند.

چکیده [English]

The purpose of this research was to examine the combination effect of action observation, motor imagery and physical training differences methods on stability of in-phase and anti-phase movements. The statistical sample included 64 girl students in physical education field with age range of 20-28 years old. Subjects were divided randomly in four experimental groups (action observation-physical training, physical training-motor imagery, action observation-motor imagery and physical training) based on inclusion and exclusion criteria. The training protocol was consisted 3 stages such as pre-training (pre-test), training and Execution (post-test) Stages. Results showed that the action observation– physical training combination group in both in-phase and anti-phase movements has better performance than other groups (P<0.001). Furthermore, the physical training – motor imagery combination group has better performance than physical training and action observation- motor imagery combination groups (P<0.05). Based on present research results could be recommended to coaches that used the action observation– physical training combination method for learning of these motor skills types.
