چکیده
هدف از این پژوهش، بررسی تأثیر سطوح مختلف خستگی ذهنی بر ظهور مهارت برجسته در بسکتبال بود. پژوهش حاضر از نوع مطالعات توصیفی- همبستگی و به لحاظ هدف، کاربردی است که با استفاده از بازیکنان بسکتبال دانشگاهی در سه سطح خستگی ذهنی ( پایین، متوسط و بالا) انجام شد. آزمودنیها (هر گروه 8 نفر)، 210 پرتاب را از هفت زاویه که از هر زاویه 30 پرتاب در سه سطح خستگی ذهنی اجرا کردند. برای تحلیل دادهها از آزمونهای رگرسیون ساده و چندگانه، تیتک نمونهای و تحلیل واریانس چند متغیره استفاده شد. نتایج آزمون رگرسیون مهارت برجسته را در اجرای هر سه گروه نشان داد. همچنین گروه خستگی ذهنی پایین عملکرد بهتری نسبت به بقیه گروهها داشت. در نتیجه میتوان گفت که با توجه به ظهور مهارت برجسته با وجود خستگی ذهنی، پارامترهای اختصاصی شده هنوز به قوت خود باقی ماندهاند و موجب ظهور مهارت برجسته شدند.

چکیده [English]
This study aimed to investigate the effect of different levels of mental fatigue on the emergence of especial skill in basketball. The study was a kind of descriptive correlational studies and was an applied research in terms of objective that was performed recruiting university basketball in three levels of mental fatigue (low, medium and high). The subjects (8 person per group) had 210 throws from seven angles (the angles of 45, 60, 75, 90, 105, 120 and 135 degrees) that conducted 30 throws from any angle in three levels of mental fatigue. The regression results showed the existence of especial skill in the performance of all three groups. Low mental fatigue Group also had better performance than the rest of groups. In conclusion, with the emergence of especial skills with mental fatigue, remain in force specialized parameterization, yet the especial skill emerged.
