تأثیر تکلیف ثانویه بر دقت پرتاب آزاد بسکتبال در شرایط انسداد تحت فشار بازیکنان ماهر

نویسندگان

چکیده
هدف از این تحقیق تعیین اثرات تکلیف ثانویه مرتبط و نامرتبط با مهارت پرتاب آزاد بسکتبال بر دقت پرتاب بازیکنان ماهر تحت شرایط انسداد بود. 20 بسکتبالیست زن (30-18 ساله) راست دست با سه سال سابقه پس از تکمیل پرسشنامه اضطراب صفتی ایلی نویز (SCAT) و دست برتری آنت (AHQ) و اندازه‌گیری‌ ویژگی‌های آنتروپومتریکی وارد مطالعه شدند. آنها‌ در دو جلسه آزمون با فاصله 2 روز شرکت کردند. در جلسه‌ اول (بدون فشار) و دوم (فشار بالا)، پس از گرم کردن به انجام 10 پرتاب آزاد در سه وضعیت 1) پرتاب آزاد بسکتبال، 2) پرتاب آزاد بسکتبال+ تکلیف ثانویه مرتبط، 3) پرتاب آزاد بسکتبال+ تکلیف ثانویه نامرتبط پرداختند. نتایج نشان داد که تکالیف ثانویه مرتبط و نامرتبط با پرتاب آزاد، بر دقت پرتاب بازیکنان ماهر تحت شرایط انسداد پایین (012/0=P، 001/0=P) و بالا (001/0=P، 018/0=P) تأثیر دارند و بین تکلیف ثانویه مرتبط و نامرتبط با مهارت بر دقت پرتاب در شرایط انسداد بالا تفاوت معنی‌داری وجود دارد (001/0=P).

به طور کلی برای کاهش فشار وارده بر ورزشکاران در شرایط انسداد می­توان از تکالیف ثانویه مرتبط و نامرتبط و همچنین، برای افزایش دقت افراد ماهر در این شرایط می‌توان از تکلیف ثانویه مناسب مرتبط با پرتاب آزاد استفاده کرد.

چکیده English

The aim of this study was to determine the effect of secondary task relevant and non-relevant to the free throw basketball skill on the free throw accuracy of basketball skilled players in choking under pressure. Twenty right-handed female players (aged 18-30) each with at least three years of experience in basketball took part study after completing the Sport Competition Anxiety Test (SCAT), Annett Handedness Questionnaire (AHQ) and measuring their anthropometric characteristics. The study included two testing sessions with an interval of 2 days. In the first and second session (no-pressure and high pressure, respectively) participants warmed up and performed 10 free throws in three conditions: 1) free throw, 2) free throw with relevant secondary task, 3) free throw with non-relevant secondary task. Results showed that the secondary relevant and non-relevant tasks to free throw have effects on accuracy in no-pressure (P=0.012, P=0.001) and high pressure (P=0.001, P=0.018) conditions. Also, there was significant differences between relevant and non-relevant tasks effects on accuracy in high pressure situation (P=0.001).

Overall, it may be used the secondary relevant and non-relevant tasks in choking under pressure situations for reduction of pressure imposed on athletes. Also, properly designed secondary tasks for free throw may be used to increase the accuracy of skilled participants under the pressure situations.
