چکیده
هدف از این پژوهش، مطالعۀ اثر خستگی بر تصمیم‌گیری و رفتار جستجوی بینایی بازیکنان مبتدی و ماهر فوتبال بود. شرکت کنندگان 14 فوتبالیست مرد مبتدی با میانگین سنی 5/22 سال و 14 فوتبالیست مرد ماهر با میانگین سنی 4/27 سال بودند. هر دو گروه ﻓﯿﻠﻢﻫﺎﯾﯽ از ﻣﻮﻗﻌﯿـﺖ 1در مقابل 1 حمله‌ای را ﻣﺸﺎﻫﺪه ﮐﺮدﻧﺪ. سپس تصمیم خود را که حرکت به چپ، راست و شوت بود در دو حالت بدون خستگی و خستگی اعلام کردند. نتایج آزمون t همبسته نشان داد که بین نمرات تصمیم‌گیری بازیکنان ماهر و مبتدی در قبل و بعد از خستگی تفاوت معنی‌داری وجود ندارد (05/0<P). تعداد و زمان تثبیت‌ها با آزمون تحلیل واریانس مرکب با اندازه‌گیری مکرر ارزیابی شد. نتایج تعداد تثبیت‌ها نشان داد که اثر اصلی سطح مهارت معنی‌دار بود (05/0>P)، امّا اثر اصلی مراحل آزمون معنی‌دار نبود (05/0<P). همچنین اثر تعاملی سطح مهارت در نقطه خیرگی، تعامل مهارت با مراحل آزمون، تعامل مناطق خیرگی با مراحل آزمون و تعامل سطح مهارت در مناطق خیرگی با مراحل آزمون معنی‌دار نبودند (05/0<P). نتایج زمان تثبیت‌ها نشان داد که اثر اصلی سطح مهارت و مراحل آزمون معنی‌دار نبودند (05/0<P). اثر تعاملی سطح مهارت در مراحل آزمون و تعامل سطح مهارت، نقاط خیرگی در مراحل آزمون معنی‌دار بودند (05/0>P). پیشنهاد می شود که بر اساس شناسایی نقاط مهم اطلاعات به بازیکنان آموزش داده شود که در شرایط خستگی به مناطق مهم‌تر توجه کنند.

چکیده [English]
The goal of this study is to compare the effect of fatigue on decision-making and visual search behavior of novice and expert soccer players. Participants were 14 male novice soccer players (mean age= 22.5 years) and 14 experts (mean age= 27.4 years). Both groups watched films of 1 Vs. 1 attack situations. Then they announced their decision to move left, right, or shoot in two circumstances of not fatigue and fatigue. The results of t-test showed that there was no significant difference between the scores of decision making of both groups in pre-test and posttest. (P>0.05).The number and duration of fixation were evaluated by ANOVA. The results of the number of fixations showed that the main effect of skill level was significant (P<0.05), but the main effect of the test stages was not significant (P>0.05). Also, the interactive effect of skill level at the gaze points, skill interaction with the test stages, interaction between the gaze areas with the test stages and interaction between the level of skill in the gaze areas of the test stages were not significant (P>0.05). The results of fixation time showed that the main effect of skill level and test stages was not significant (P>0.05). The interactive effect of skill level in the test stages and interaction of skill level, gaze points in the test stages were significant (P<0.05). It is suggested that players to be trained to pay attention to critical points of opponents body in fatigue situations.
