Different Levels Of Women's Football Players In Tactical Situations Research On Visual Search Features

In football scenes,players need to observe complex situations at any time and make corresponding action choices.Eye movement recording can objectively show the process of effective information processing of football players in sports situations.This research adopts the "experts-new research paradigm",in a different sport level of women's football athlete as the research object,combines the technique of eye movement record to circumstances in the offense,discusses different levels of the women's athletes in the tactical decisions in the process of cognitive regularity and characteristics of visual search and provide theoretical basis for improve the visual search ability of athletes.In circumstances of football tactics,visual search in different levels of the women's athletes have adopted different eye patterns,expert and novice group in football tactics scenario,two groups of participants in the eye patterns when searching for information is shown as: the panel's visual search visual search speed faster,faster than a novice group expert group than novice group in a tactical choice way more reasonable;Panel can in a short period of time to quickly search information effectively,the important area of information looking time is long,the panel in the three sites are looking times the average of less than novice group,the expert group compared with the novice group,looking at different areas,the expert group in different parts of the fixation point distribution is more law,show the fixation point more broad,and focused.The fixation trajectory of the expert group in different regions is shown as cyclic and repeated fixation,and the all-round fixation in different regions;In the novice group,there was no uniform pattern of fixation trajectory,and the fixation trajectory in different areas was single and scattered.Research conclusion:In the context of football tactics,the process of information processing and tactics selection is as follows: the agility of expert group is better than that of novice group;The expert group has a more reasonable tactical choice than the novice group.In the context of football tactics,in terms of fixation time and fixation frequency indicators,the expert group has more effective information than the novice group,more fixation times for important areas,longer fixation time and faster visual cognitive processing.In the context of football tactics,in terms of the gaze trajectory indicators,the focus of the focus trajectory of the expert group on the important areas,the all-round gaze of different areas,the novice group's gaze trajectory is relatively scattered,single.In the context of football tactics,through the analysis of the rationality of the response time and the tactical choice of the expert group and the novice group,the agility and the rationality of the tactical choice of the two groups of subjects are different because of the difference in the central nervous system processing information "capacity".
