Abstract
Objective: Mental fatigue, which is defined as the result of performing a hard cognitive activity, can disrupt visual search, speed of movement, or tactical choices in sports, so the purpose of this study was to investigate the effect of mental fatigue on the pattern of gaze behavior and decision-making in the badminton overhead shot.
Methods: The current research is a semi-experimental type that was conducted in pre-test and post-test with the control group. For this purpose, 36 students (age: 20-35, gender: female) from Alzahra University were selected as the available sample. The participants were randomly divided into the mental fatigue and control groups. In the pre-test, a 20-test video of badminton overhead shots was shown, interrupted at the moment of the racket-ball contact. Participants decided the direction of the shot while wearing an eye-tracking device. 48 hours after the pre-test phase, the participants filled out the visual analog scale questionnaire to measure mental fatigue before and after the Stroop test for 60 minutes. The control group did their daily routine, then the post-test was performed according to the pre-test steps.
Results: The results showed that mental fatigue led to an increase in the number of fixations and a decrease in fixation duration, and the decision-making accuracy decreased and its time increased.
Conclusions: The results show that mental fatigue disturbs the accuracy and speed of decision-making in badminton. These disturbances are probably related to changes in visual search behavior.
