چکیده
هدف از این تحقیق بررسی اثر دستورالعمل‌های کانون توجه بر کارامدی عضلانی و عملکرد حرکتی افراد ماهر بود. طرح تحقیق پیش‌آزمون- پس‌آزمون، 30 گلف باز ماهر مرد با دامنه سنی 28 تا 32 سال به‌صورت داوطلبانه انتخاب، و به‌صورت تصادفی در 3 گروه 10 نفری توجه بیرونی، درونی و کنترل قرار گرفتند. شرکتکنندگان در پیش‌آزمون، به اجرای 20 کوشش ضربه گلف پرداختند؛ و همچنین EMG عضلات دلتوئید، تحت کتفی و درون گرداننده گرد نیز ثبت گردید. مداخله در 3 روز متوالی انجام گرفت که در هرروز، آزمودنی‌ها 20 ضربه گلف را اجرا کردند و همچنین هم‌زمان با اجرای ضربات EMG عضلات نیز ثبت گردید. بعد از اتمام جلسات تمرین، پس‌آزمون ضربه گلف در 20 کوشش مشابه با پیش‌آزمون اجرا گردید. همچنین در مرحله پس‌آزمون مشابه با پیش‌آزمون EMG عضلات دلتوئید، تحت کتفی و درون گرداننده گرد نیز ثبت گردید. دادهها به روش تحلیل واریانس مرکب تحلیل شد. نتایج در بخش رفتاری نشان داد که بین دقت ضربه گلف در گروه‌های تحقیق تفاوت معناداری وجود دارد؛ که این تفاوت‌ها به نفع گروه توجه بیرونی بود. همچنین نتایج این تحقیق در بخش نوروفیزیولوژیکی نشان داد که از بین گروه‌های تحقیق گروه کانون توجه بیرونی منجر به کاهش معناداری در میانگین فعالیت عضلات شد که این کاهش نتیجه در اقتصاد بیشتر حرکت و روان‌تر بودن حرکت می‌دهد. این پژوهش نشان می‌دهد که در هر دو بخش رفتاری و نوروفیزیولوژیکی یک استراتژی کانون توجه بیرونی می‌تواند جهت بهبود دقت ضربه و کاهش فعالیت الگوی عضلانی در افراد ماهر مفید و مؤثر باشد.

چکیده [English]
The aim of study was investigate the effect of focus of attention instructions on muscle efficiency and motor performance of skilled Individuals. In this semi-experimental study with a pre-test-post-test research design, 30 skilled male golfers with an age range of 25 to 35 years were voluntarily selected and randomly divided into 3 groups of 10: external focus, internal and control group. In the pre-test, the participants performed 20 golf Putting trials; Also, EMG of deltoid, subscapular and Pronator teres muscles were also recorded. The intervention phase was carried out in 3 consecutive days, and on each day, the subjects performed 20 golf Putting, also, the EMG of the muscles was recorded simultaneously with the execution of the golf Putting. After the training sessions, the golf shot post-test was performed in 20 trials similar to the pre-test. Also, in the post-test phase, similar to the pre-test, the EMG of the deltoid, subscapular and Pronator teres muscles was also recorded. The data was analyzed by the Mix variance analysis method. The results of the behavioral section showed that there is a significant difference between the accuracy of the golf putting in the research groups; that these differences were in favor of the external focus group. Also, the results of this research in the neurophysiological section showed that among the research groups, the external focus group led to a significant decrease in the average activity of the muscles, which resulted in greater economy of movement and smoother movement.
