Introduction: vision is one of the most important senses in sports performance, which gives the athlete the ability to interpret spatial orientation information, timing, organ coordination, balance, reaction to stimuli and predicting actions. Cognitive styles affect people's performance and learning. Response inhibition is defined as a person's ability to inhibit some cognitive or behavioral responses. Response inhibition, which is one of the cognitive components, which is the ability to suppress responses, associations, and pay attention to irrelevant stimuli, which plays an important role in visual tracking, memory, word retrieval, and problem solving. It should be noted that response inhibition is also dependent on the information available from vision. Is. The current study was the effect of sports vision and handball exercises on the inhibition control and handball shot accuracy of beginners.
Key words: vision exercises, response inhibition, pattern and accuracy
Methodology: The type of research was semi-experimental and pre-test-post-test with a control group. To evaluate the three-step jump test, the participants made three attempts, and for the accuracy test, they performed 5 throws for each hand (left, right), and a computerized Stroop test was performed to measure response inhibition. The statistical population included female students of Shahid Beheshti University who did not have vision problems. 20 students in the age group of 24-18 were selected as available and were homogeneously divided into 2 groups of 10 people. Both experimental (combined) and control (physical) groups performed their respective exercises for six weeks and two sessions a day.
For data analysis, compound analysis of variance (2*2) was used with the between-group factor of group and the within-group factor of time at a significance level of 0.05. Also, the independent t-test was used to compare the performance of the experimental and control groups in the pre-test and post-test, and the dependent t-test was used to compare the performance of the control group in the pre-test and post-test.
Findings: Based on the statistical findings to improve response inhibition, it showed that the reaction time and error rate in the Stroop test in the pre-test and post-test were not significant between the two groups, but the accuracy in the Stroop test was significant (p=0.05) and also in the shot accuracy. Handball, the difference between pre-test and post-test in both experimental and control groups was significant (p=0.01).
Discussion and conclusion: The results showed that visual training has improved the cognitive skill of response inhibition, so it is recommended to use visual skills training to improve cognitive skills. And visual training improves the accuracy of the three-step shot and the correct pattern of the three-step shot in handball players, so it is suggested to use this type of training along with other specialized exercises of this sport.
