چکیده

زمینه و هدف: از آن­جا که اضطراب از جمله عوامل مؤثر بر عملکرد ورزشکاران به‌شمار می­رود، پژوهش حاضر با هدف بررسی اثربخشی تحریک الکتریکی فراجمجمه­ای مغز در کاهش اضطراب ورزشکاران رزمی‌کار انجام شد
مواد و روش­ها: این پژوهش از نوع نیمه‌آزمایشی با طرح پیش‌آزمون-پس‌آزمون با گروه کنترل بود. جامعه آماری پژوهش حاضر، دربرگیرنده کلیه ورزشکاران رزمی‌کار شهر اردبیل در سال 1401 بود که با روش نمونه­گیری در دسترس از ورزشکاران رزمی‌کار شهر اردبیل 30 نفر انتخاب شد. آزمودنی­ها به‌صورت تصادفی ساده در دو گروه آزمایش و کنترل (15 نفر در هر گروه) جایگزین شدند. گروه آزمایش تحت 10 جلسه 20 دقیقه­ای تحریک الکتریکی فراجمجمه­ای مغز قرار گرفت. گروه کنترل مداخله­ای را دریافت نکرد. از پرسش‌نامه اضطراب حالت- صفت (مارتیز، 1990) در دو مرحله پیش­آزمون و پس­آزمون به‌منظور جمع­آوری اطلاعات استفاده شد. داده­ها با استفاده از نرم­افزار SPSS و تحلیل کوواریانس چندمتغیره تجزیه‌وتحلیل شدند.
یافته ­ها: نتایج نشان داد بین نمرات پس­آزمون گروه آزمایش نسبت به گروه کنترل، تفاوت معنی­داری وجود داشت. به عبارت دیگر، تحریک الکتریکی فراجمجمه­ای مغز منجر به افزایش معنی­دار نمرات اعتمادبه‌نفس و کاهش معنی­دار نمرات اضطراب جسمانی و شناختی ورزشکاران شد (0/05>P).
نتیجه‌گیری: براساس نتایج این پژوهش، درمان تحریک الکتریکی مستقیم مغز، مداخله مؤثری در کاهش اضطراب ورزشکاران رزمی‌کار است و راهی مناسب، کم‌هزینه و در دسترس است که ورزشکاران می­توانند از آن استفاده کنند.

چکیده [English]

Introduction: Since the anxiety is one of the effective factors in athletes, The aim of this study was to evaluate the effectiveness transcranial direct current stimulation (tDCS) on reducing anxiety in Martial Athletes.
Materials and Methods: The research method was semi-experimental with a pretest-posttest design and control group. The statistical population of the present study consisted of all Martial Athletes in Ardabil in 2022. 30 people were selected by available sampling method and randomly assigned in experimental and control group (15 people in each group). Transcranial direct current stimulation (tDCS) was implemented in 10 sessions, each session lasting 20 minutes, but the control group received no training. Data was collected using State-Trait Anxiety Questionnaire (Moritz, 1990), which were administered in two stages of pre-test and post-test. Data were analyzed using SPSS software and multivariate analysis of covariance (MANCOVA).
Results: The results showed that there was a significant difference between the post-test scores of the experimental group compared to the control group. In other words, transcranial direct current stimulation (tDCS) led to a significant increase in the self-confidence scores and a significant decrease in the physical and cognitive anxiety scores of the athletes (P<0.05).
Conclusion: According to the results of this study, the treatment of transcranial direct current stimulation is an effective intervention on reducing anxiety in Martial Athletes and is a suitable, low-cost and accessible way that athletes can use.
