Study On Eye Movement Characteristics Of Female Football Players In Open Scenes

From the perspective of athletes’ special cognitive level,it is an important research topic of sports psychology to explore the development characteristics of special sports psychological ability and reveal the training mechanism of special sports psychological ability.In the process of sports,visual information extraction is its basic psychological support.Different patterns of visual information extraction may reflect the difference of cognitive ability between high-level athletes and general-level athletes.Eye movement analysis is considered to be one of the most effective means to study the process of visual information processing,and has been widely used in the study of various sports.Based on the theory of information processing and using different football offensive videos as experimental materials,this paper studies the eye movement characteristics of football players in judging the process of offensive mode in open scenes.Eighteen participants participated in the experiment.Two participants whose eye movement characteristics were not obvious were excluded.The remaining 16 participants were divided into expert group and novice group according to the level of football.The expert group consisted of eight participants in women’s Football League matches.The long-term systematic participation in training and competition lasted for more than four years.The novice group consisted of eight football students from Sports College of Liaoning Normal University.Form All subjects had a certain football foundation,normal vision or corrected vision(corrected visual acuity reached 5.0),colorless blindness,weak color,physical and mental health.In the experiment,three-to-three counter-shot video of simulated real competition was used as stimulating material.Dikablis Pro head-mounted eye tracker produced by Ergoneers in Germany was used to analyze the eye movement index of athletes in the judgment process.The eye movement data were analyzed by D-Lab software and SPSS21.0 statistical software.Research conclusions:(1)From the analysis of decision-making response indicators,the rationality and agility of tactical choice of expert group subjects are higher than that of novice group subjects.(2)From the analysis of the time and frequency of gaze,the eye movement characteristics of expert group subjects show the characteristics of more gaze and less glance.This gaze way is more conducive to athletes to obtain effective information of competition and provide effective help for athletes to make tactical choices more quickly and accurately.(3)From the analysis of the distribution of the gaze area,the group of experts focused more on the observation of meaningful offensive clues such as running and empty space of their own players,while the gaze time of defensive elements was shorter.Meanwhile,the group of experts focused on a wider range of subjects to avoid the omission of effective information on the field.(4)According to the analysis of the dispersion degree of eye gaze in each gaze area,the visual concentration ability of expert group participants in a single gaze area is stronger,and the dispersion degree of longitudinal gaze point is much less than that of horizontal gaze point;there is no significant difference between different gaze areas.
