چکیده

ممقدمه و هدف: امروزه کسب موفقیت ورزشی بدون توجه به مهارت‌های روان‌شناختی امکان‌پذیر نیست. هدف پژوهش حاضر بررسی اثر یک دوره تمرین مهارت‌های روان‌شناختی بر عملکرد ورزشی مهاجمان فوتبال ساحلی شهر سمنان بود.
روش شناسی: به این منظور، سه نفر از مهاجمان حاضر در لیگ تیم فوتبال ساحلی شهر سمنان، به‌صورت نمونۀ در دسترس انتخاب شدند. در این پژوهش از طرح تک‏آزمودنی با خط ‎پایۀ چندگانه جهت بررسی عملکرد ضربۀ سر دقیق، شوت صحیح و پاس دقیق استفاده شد. پس از اعمال یک دورۀ برنامۀ تمرین مهارت‎های روانشناختی به منظور بررسی تغییرات نیم‌رخ عملکرد شرکت‌کنندگان نسبت به قبل و بعد از مداخله از شاخص ام.بی.دی و اندازۀ اثر با محاسبۀ دی‌کوهن استفاده شد.
یافته‌ها: در این پژوهش آزمودنی‌ها در مجموع به 66/50% بهبودی و اندازۀ اثر 57/3 در عملکرد ضربۀ سر دقیق، 52% بهبودی و اندازۀ اثر 4/3 در عملکرد درصد شوت صحیح و همچنین به 46/54% بهبودی با اندازۀ اثر 61/3 در عملکرد پاس دقیق دست یافتند که به ترتیب به معنای بهبودی نسبی و معناداری آماری می‌باشد.
بحث و نتیجه‌گیری: نتایج این پژوهش نشان می‌دهد که تمرین مهارت‌های روان‌شناختی زمینه ساز بهبود عملکرد ضربۀ سر دقیق، شوت صحیح و پاس دقیق و به‌تبع آن بر عملکرد ورزشی فوتبالیست‌های مهاجم رشتۀ فوتبال ساحلی است. احتمالاً افزایش خودآگاهی ورزشکاران نسبت به نقاط قوت و ضعف خود زمینه‎ساز این تغییرات بوده است . بنابراین پیشنهاد می‌گردد مربیان و روان‌شناسان ورزشی از این تمرینات برای بهبود عملکرد ورزشکاران خود استفاده کنند.
