چکیده
هدف از اجرای پژوهش حاضر، تعیین تأثیر تمرین نروفیدبک با تأکید بر برتری دستی بر یادگیری مهارت پرتاب دارت بود. 39 دانشجوی دانشگاه شهید رجایی تهران (میانگین سنی: 57/2 ± 62/21 سال) به‌طور هدفمند در این پژوهش شرکت کردند. شرکت‌کنندگان پس از آموزش و مشاهدة فیلم مربوط به مهارت پرتاب دارت و اجرای پیش‌آزمون (10 کوشش) در یکی از گروههای نروفیدبک راست‌دست، نروفیدبک چپ‌دست، کنترل راست‌دست و کنترل چپ‌دست قرار گرفتند. مرحلة اکتساب شامل هشت جلسه تمرینی بود که در آن شرکت‌کنندگان در هر جلسه 20 کوشش تمرینی را پس از مداخلة نروفیدبک انجام دادند. 72 ساعت پس از اتمام مرحلة اکتساب، آزمون یادداری و سپس آزمون انتقال با دست غیربرتر انجام شد.تحلیل یافتهها در مرحلة اکتساب نشان داد که اثر جلسات تمرین معنادار است؛ به‌عبارت‌دیگر، عملکرد پرتاب دارت شرکت‌کنندگان در طول جلسات تمرینی پیشرفت معناداری را نشان داد. همچنین، نتایج تحلیل واریانس یکراهه نشان داد که تفاوت بین چهار گروه تمرینی در آزمون یادداری معنادار است؛ به این معنی که هریک از گروههای نروفیدبک در آزمون یادداری، نمرات بیشتری را در مقایسه با گروه کنترل به دست آوردند؛ اما تفاوت معناداری بین گروه نروفیدبک راست‌دست و چپ‌دست وجود نداشت. از سوی دیگر، گروههای آزمایشی در مرحلة انتقال، تفاوت معناداری با یکدیگر نداشتند. پروتکل اس‌ام‌آر/تتا با تقویت ریتم حسی ـ حرکتی و به دنبال آن بهبود فرایندهای توجهی، به ارتقای عملکرد در مهارت پرتاب دارت منجر میشود و به نظر میرسد استفاده از این پروتکل میتواند به تسریع روند خبرگی در رشتة دارت کمک کند.

چکیده [English]
The purpose of this study was to investigate the effects of neurofeedback training with a focus on handedness, on learning of dart throwing skill. Thirty-nine Students of Shahid Rajaee Teacher Training University )mean age: 21.62±2.57 years) purposefully participated in this research. After instructing and observing dart throwing film by participants, a pretest includes of 10 trails was conducted and then participants were assigned into four groups (right-handed neurofeedback, left-handed neurofeedback, right-handed control and left-handed control) according to pretest scores. Acquisition phase includes of 8 training sessions, participants completed 20 trials per session after neurofeedback intervention. 72 hours after the last training sessions, the retention test and then transfer test with non-dominant hand was conducted. Factorial analysis of variance with repeated measures on training sessions indicated that training sessions main effect was significant, that is, participants showed significant improvement in dart throwing performance during acquisition phase. In addition, one-way ANOVA revealed that there were no significant differences among groups in transfer test, while this difference was significant in retention test. In other words, neurofeedback groups achieved better scores than control group, but significant difference between right-handed and left-handed neurofeedback groups was not found. Theta/SMR protocol leads to sensory motor rhythm and attentional process enhancement, consequently increase in dart throwing performance. It appears that this protocol may help accelerating expertise process in dart.
