A Research On Performances And Differences Of Prejudgment Of Table Tennis Players In The Per-motion Situation

Table tennis is an action of fine, technical and tactical flexibility, intenseconfrontation athletics project. Before the table tennis players only to make themovement on the other side, through the extraction and analysis of field informationfast, accurate, can accurately predict to each other to find the direction of the ball.In order to more systematically and comprehensively understand athletes suchhigh strategic project of information utilization and processing process, it is necessaryto different amount of information in the context of action before the athletes predictperformance are discussed. Therefore, in this study, Capital Institute of PhysicalEducation table tennis majors and non-major students as subjects, by far closer to thereal scene shooting game for college table tennis athletes in the forehand attack usingvideo, video clips and video barrier technology, carries on corresponding processingto the obtained video material, and then through the processing of the video programon the subjects of experiment and obtain experimental data. Different amount ofinformation analysis of game and different operation scenarios of table tennis playerson the ball line predict the speed, accuracy and confidence characteristics, analysis oftable tennis beginners and experts in table tennis ball line expected differencejudgment; exploring thinking activity characteristics in the return process of tabletennis players.The results are as follows:1. Table tennis players have obvious anticipation phenomena in the opponentwill make back the ball before the situation, the prediction performance: on the onehand because of different subjects and differences, on the other hand, because of theinformation before in the context of different differences.2. The expert group of athletes’ anticipation accuracy higher than the group ofathletes, the expert group athletes’ anticipation reaction is faster than the novice group,that prediction accuracy and speed of response is effective index to evaluate the levelof athletes. Different level of choice reaction time, predict self-confidence nodifferences between the groups, that choice reaction time and predict self-confidencefor athletes before the situation to predict performance has no significant effect,effective evaluation index and its not the athletes level. Description of athletes ofdifferent levels to predict performance differences mainly manifested in two aspects:prediction accuracy and prediction speed. 3. The action scenes before the different amount of information, the prejudgmentperformance differences. With the increased action of the scene can be extracted andthe amount of information, the two groups of subjects to predict performance isimproved and the expert group changes more obvious than novice group. Group ofexperts on the action those athletes before the scene information extraction and usemore fully, more quickly.4. Table tennis athletes in the game quickly and accurately predict, largely due totheir entire game information acquisition and analysis.
