Different Levels Of Taekwondo Athletes Predict The Eye Movement Characteristics Of Opponents When Using Offensive Techniques

In sports,the sport ability of high level athletes and the low level differences often lead to differences in their way of visual search.The extraction of visual information is the study of athletes psychological activity effective method.Nowadays,science and technology unceasing development,the eye-movement apparatus has been widely used in various fields,eye movement analysis be explore visual information processing features one of the most effective means.This study taekwondo sport-specific as the breakthrough point,visual information processing theory as the starting point,with special cognitive eye movement characteristics of taekwondo athletes as the core,the use of advanced eye movement instrument equipment to understand visual search characteristics of taekwondo athletes.Choose different levels of taekwondo athletes,this study adopts a new paradigm,developed by using the ASL laboratory ASL-H6 wearing eye tracking system records the different levels of taekwondo athletes anticipation competitors use attack technology of reaction time and accuracy motion decision reflect index,quantity and fixation time and total fixation point,the size of the pupil,the interest area gaze number,stay time,gaze fixation point percentage and eye movement indices such as eye movement trajectory.By SPSS19.0statistical software as tools to the corresponding data statistics and analysis,understand the subjects in the process of visual information processing and dynamic note that search path and psychological activity process,find out the differences of different levels of taekwondo athletes,athletes visual search rule,enrich the existing sports psychology research,reveal the monitoring information of different levels of taekwondo athletes and combined with psychology,sports training theory,draw anticipation taekwondo offensive attack technology and concealment training method,in different levels of taekwondo athletes training,improve the training effect.The results show that:1.The different levels of taekwondo athletes in anticipation opponent using the reaction time and accuracy of attack techniques have significant difference,high level athletes is shorter and more accurate;Three experiments increasing difficulty,the control group and experimental group participants,as the task harder,two groups of participants accuracy will reduce gradually,the low level athletes are more significant changes.2.In anticipation opponent attacking skills,high level of taekwondo athletes fixation point number is more,in the process of visual search and distribution is more concentrated,more distributed in the upper part of the key areas;And the low level taekwondo athlete has a large number of fixation points,the distribution is more diffuse,there is no law,the target is blurred,the search efficiency is relatively low.The expert's ineffective gaze is significantly less than the novice.3.The pupil of the high level taekwondo athlete is slightly larger than the low level taekwondo athlete when the opponent USES the offensive technique.4.When the opponent USES offensive technology,the number of interest areas of the different level of taekwondo athletes and the duration of the fixation time are significantly different.High levels of interest in high level athletes are high and there is more time to stay in critical areas.5.Anticipation opponents use attack,high levels of taekwondo athletes watching interest area percentage points higher than the low level of taekwondo athletes,tend to focus on key areas;Low levels of taekwondo athletes are more likely to be free from the critical areas and less efficient.6.High level athletes eye movement trajectory is relatively simple and clear,the path is clear,back to the point of view,the distribution is relatively concentrated,accurate observation area,watching track formed in the opponent the upper part of the area,and low level of taekwondo athletes track complex,back to the point of view,throughout the whole body,formed in the lower area of the athletes.7.From the experimental results of the distribution of the two groups of subjects,the experimental group was found to be located on the top of the torso,and concentrated in the area of the trunk.And the control group is more dispersed,and the population is generally lower;The experimental group focused on the start of the technique,while the control group focused on the end of the technique.8.Anticipate the better time and body parts of your opponent's offensive techniqueStraight punch: when the starting stage of the punch is in the shoulder,the shoulder is better than the time point of the shoulder,and the shoulder is the better part of the pre-judged technique.Turning kick: the waist of the shoulder begins to move forward quickly to better predict the time,shoulder,chest,abdomen is the better pre-judged area.Front legs kick: the beginning stage of the front leg kick,the front shoulder begins to move forward to the better pre-judged time point,the front shoulder is a better pre-judged area;The front shoulder up is also a prejudged time,but it is not the best,and the pre-judged area is the front shoulder.The shoulder begins to rotate inward,the front leg has finished lifting the hip,the final judgment time,then the prejudgment should focus on the knee joint of the front leg.Axe kick: from the position of preparation to the starting position of the lower cut,a better pre-judged time point,head,shoulder,chest,and hip are preferred.The start point is also a prejudged time point,but not the best one.Dack kick: when entering the body of the body,it is better to prejudge the time,the head is thebetter pre-judged area.360°kick: at the beginning of the movement,the head becomes a better pre-judged time point when the head starts to turn.Reverse kick: after entering the swing stage of the kick,the hip starts to contract quickly and is a good time to prejudge,and the waist-hip area is a better pre-judged area.
