| Prediction refers to pre-estimating the events that have not yet occurred or are happening,and are not clear enough,and speculate on the future development trend of things,in order to help them grasp the law of things development and other conditions in order to make the most reasonable judgment And decision making.Tennis is a skill-led segregated net confrontation project,and the technical and tactical changes are varied.Athletes need to quickly predict the event and make decisions in a very limited time.Receiving and serving technology is one of the most important technical links in tennis,and it is also an important link in the game.The unique rules of tennis make the sport full of charm.Athletes want to break the balance of the game,they have to make breakthroughs in the opponent's serve.This requires the athlete to have a good ability to receive and serve in the game and be able to judge in time.Fast movement,and accurate response to the ball,which shows that the ability to receive the ball is very important in the game.With the continuous improvement of the current tennis technical and tactical capabilities,the speed of tennis hitting is getting faster and faster,especially in the process of the opponent's serving,the receiving party needs to quickly and effectively identify the incomplete hitting information in a very limited time,And make judgments and decisions,in order to reduce the chance of opponents scoring directly.Therefore,the research on the pre-judgment ability of serve will help to deeply understand the information processing characteristics of high-level athletes during the pre-judgement process,and can find the factors that affect the accuracy of the athletes 'pre-judgement,and further provide a theoretical basis for the improvement of athletes' athletic ability 3.Experience guidance.Predictability is a very important psychological quality for environment-led projects.In order to explore the differences between the tennis players of different experience levels in receiving and the neural mechanism behind them,this study adopts the expert-sub-expert-novice paradigm,and selects 20(21.05 ± 1.395)second-level and above sports training students as the expert group.20(22.30 ± 1.129)junior and senior junior college students who teach tennis as the intermediate level group,and 20(21.85 ± 1.309)public sports tennis elective students as novice groups,with the help of time blocking technology and E-prime3.0 programming conducts experimental research on three different levels of subjects.In the pre-judgment service experiment,the results show that: in the behavior experiment of viewing the service picture material:(1)there are significant differences in the pre-judgment of the service training group,the sports education group,and the public body group for the service reception.The specific advantages are: operation training group> sports education group> public sports group;(2))in the picture materials at different time points(time 1,time 2,time 3,time 4),the pre-judgment performance of each group of participants It is: time 4> time 3> time 2> time 1.The high-level group can obtain more early action information in the pre-judgment task;therefore,the perceptual prediction in each time series is faster than the intermediate level group and the novice,and the accuracy is higher.Through further analysis of the above experimental results,we have summarized the following conclusions:(1)High-level players have a deeper understanding of the sports scene,and they are fast and accurate in the pre-judgment process,showing obvious advantages.(2)After long-term training of athletes,the advantages of athletes' information processing capabilities have been expanded.(3)High-level athletes can quickly use the information highly related to the task in the stimulation task.(4)High-level athletes can activate the corresponding brain regions earlier,use their memory systems accumulated for a long time to estimate and make decisions,and use top-down information processing methods. |
