Research On Attention Network Characteristics Of Different Levels Of Junior Football Players

Posner and Petersen propose to divide attention into three networks,alertness,directed,and execution functions.ANT test and its calculation method are important tools for the test of attention networks.Physiology,neuroimaging and behavioristics have proved that the three networks are independent and organically unified from different angles.This time we used fNIRS technology to measure alertness networks,orientation networks and execution functions for three different levels of youth football players.We compare behavioral and image analysis to see if there is a significant difference between alertness networks,directed networks,and executive functions between different groups.We discuss and analyze the causes in the results obtained,and explain and forecast the relationship between network characteristics research and youth football training,and discusses the effects caused by the subcomponents of attention networks.In this experiment,three control groups were selected.Each control group selected 20 young football players of different levels with similar age and gender balance,and ensured that the subjects' favorable hands were right hands and their anxiety level and intelligence were normal.Results: Behavioral outcomes were not significantly different between alertness network efficiency and directed network efficiency.Executive Function Efficiency is Professional Group > School Team > General Group.The imaging results show that there is no significant difference between the alertness network and the directed network in the affected activation area and there was no significant difference in pairwise comparison of blood oxygen change.Execution function activation area professional group > school team > general group.In the professional group,the dorsolateral prefrontal lobe and the right temporoparietal lobe were significantly activated.Based on the experimental results,this paper analyzes and discusses the athletes' training level,training period and training environment.At the same time,it proposes the innovation and deficiency of the research using the fNIRS technology and the attention network characteristics of young football players.It looks forward to the in-depth study of the network functions of young football players in the future and how to apply the attention function to the selection and training of athletes.
