Experimental Study On The Characteristics Of Eye Movement In The Preset Passing Direction Of Basketball Players At Different Levels

With the improvement of basketball competition level,the competition of basketball players on the field is becoming increasingly fierce.Vision is the main way for athletes to obtain information in the game.Studies have shown that there are differences in eye movement characteristics such as visual response and pre-judgment accuracy of athletes at different levels during exercise,and good visual response.And pre-judgment accuracy has a very important role in motion decision-making and behavioral execution.Eye movement characteristics are closely related to human information processing and psychological cognition.The passing process of basketball players on the court is a process of rapid information processing and behavioral operation of athletes' brain.The research on the eye movement characteristics of basketball players is to further clarify the visual response time and the accuracy of visual pre-judgment affecting athletes.The physical and mental factors of behavioral decision making make it important to enhance the athlete's behavioral decision-making ability in the arena.Based on the existing research,this study selects college students' high-level basketball players and ordinary college basketball players as the research objects.Through the Insight Eye Tracker of Beijing Mind Ark Company,the eye movement characteristics of basketball players of different levels in pre-judgment pass are carried out.Experimental research,the results are as follows:1.The experimental results of the pre-judgment response and the pre-judgment correctness rate of the two groups of participants were: the professional group was tested and the non-professional group had significant differences(t reaction =-4.702,t correct)Rate = 5.143,p < 0.05),the professional group basketball players have higher pre-judgment correct rate than the non-professional group basketball players,and use less time;male subjects and female subjects have significant differences(t professional-male-female reaction Time =-3.27,t non-professional-male and female reaction time = 2.4,t professional-male and female pre-judgment correct rate = 2.437,t non-professional-male and female pre-judgment correct rate = 3.235),male basketball player predicts reaction when compared with female basketball player Fast,and the correct rate is also higher;in the variance analysis of group and gender factors and reaction time and pre-judgment correctness rate,the two main effects are significant(F reaction-group = 41.158,F-reaction-gender = 40.483),the interaction effect is not significant.2.The experimental results of gaze time and number of gaze at different positions in the two groups were: there were significant differences in gaze time and gaze times between the subjects in the professional group and the non-professional group.In the professional group,the subjects in the "ball-handed hand","offensive position" and "defender position" were longer than the non-professional group,and the number of gaze was more than that of the non-professional group;In the professional group,the subjects in the "bearer's head","the ball-bearer's foot","ball" and other positions were more gaze-keeping and gaze times than the professional group.There were significant gender differences in the subjects in the professional group,and the gender differences in the non-specialized subjects were not significant.In the analysis of variance between the two factors of group and gender and the time of gaze and the number of gaze,the group was found to be the main factor affecting the change of the dependent variable.3.The experimental results of the two groups of subjects in the blinking frequency are: the number of blinks in professional basketball players is significantly different from that of non-professional basketball players(Z professional group-non-professional group =-3.773),and the number of blinks of professional basketball players Less,indicating that the professional group basketball players are more focused in the experiment.There was no significant difference in the number of blinks between the male basketball player and the female basketball player(Z-men test-female subject = 1.423),indicating that the number of blinks may not be affected by gender.4.The correlation between the two groups in the response time,the correct rate,the blinking,and the gaze time and the number of gaze in different positions were: the indicators that were positively correlated with the response time and the correct rate in the professional group were only " The gaze time and the number of gaze at the two positions of the ball holder's head and the ball holder's hand;the position that is positively correlated with the correct rate in the non-professional group is " the player's hand The number of gaze,while the reaction has no positively significant relative position.In basketball teaching and training,we must not only pay attention to the training of skills and tactics,but also focus on the training of visual predictive ability,so that it can respond quickly and accurately in behavior decision-making.Paying attention to the training and improvement of information processing and attention distribution ability of athletes at different levels,it is necessary to implement dynamic monitoring to discover the individualized characteristics of athletes' decision-making ability in behavioral performance,to teach students in accordance with their aptitude,and to target athletes efficiently.Scientific training.
