| The volleying technique,one of important contents in tennis teaching,is a highly aggressive technical action.Generally,high-quality volley has the characteristics of fast speed,powerful strength,open angle and strong threat.And it can be used as an important means of scoring points in a game.Therefore,in the tennis game,athletes need to use the incomplete information on the court to quickly predict the trajectory and landing point of the volley and make sufficient preparations for the returning strategy.This research adopts the expert-novice research paradigm with the perspective of sports cognitive psychology.In this experiment,15 tennis special college students with the national second-level qualification were randomly selected from Shenyang Sports University as the subjects of the expert group,and 15 college students from minor class were selected as the novices group.With the application of eye-movement recording method,the thesis recorded the behavior of predicting the falling points of volley and their eye movements at different levels in the context of different time pressure and different information.With comparison,this thesis disclosed the advantages of the expert group on predicting the point,which can provide a reference for the teaching of tennis volleying.Through the processing and analysis of the experimental results,the conclusions are as follows:(1)The higher the level students have,the more obvious the advantages of volleying falling point prediction is.Compared with students of minor classes,tennis professional students enjoy the advantages of quick response and high accuracy in prediction.(2)The more sports experience students have,the more significant the advantage of information search and processing for tennis learners is.Compared with the students in the minor classes,the information searching and processing ability of the tennis professional students have the advantages of stronger initial representation ability,more concentrated and regular watching position,less watching times and shorter duration of the first watching point.(3)Different time pressures have different effects on the prediction of tennis learners.Compared with students in minor courses,the prediction of tennis professional students is less affected by the change of time pressure.(4)Different information content has different influence on the prediction of tennis learners.Compared with students of minor courses,tennis professional students have significant advantages in their ability to start in advance and their ability to start regularly under different information content situations. |
