Research On New Material Table Tennis Ball(40~+) For Technological Change Of The Top Level Man Players With Shake-hand Grip Loop

This paper focuses on investigating the technological characteristics of top level man players in using new material table tennis ball(40~+)with shake-hand grip loop.And It will also offer theortical reference for the table tennis exercise and matches in new table tennis era.In this paper,the author uses documentary analysis method,video statistics method,expert interview method and data collection method to make a systematical analysis and research on 34 mathes during new material table tennis ball age and celluloid table tennis ball era.The conclusions are as follows:(1)Comparing with the techniques in using celluloid table tennis ball,internal pull technology frequency of man players in using new material table tennis ball is less.There are great difference in the using techniques in celluloid table tennis ball and new material table tennis ball.The using frquency of pendulum technique with new material table tennis ball is less than that of celluloid table tennis ball.Within it there are great difference.The material of the table tennis ball has been changed and the ball has been enlarged.With which,the drage force of air among the rotation,speed and energy of table tennis ball will be enlarged.And in this situation,players can not internally pull the ball very well.With which,it is no good for the next ball.There is great difference in internal pull technique with the application of new material table tennis ball and celluloid table tennis ball.And with this,it is harder for player to gain score by using internal pull techniques.Hence,the frequency of using internal pull techniques decreases.(2)There is a variety of differences in the application of new material table tennis ball and celluloid table tennis ball such as serving ball and catching ball.It is harder to gain score in serving ball with the application of new material table tennis ball.(3)The most frequent technique in the horizontal position loop of using new material table tennis ball is backhand loop technique.The score of backhand loop in using new material table tennis ball is different from that in using celluloid table tennis ball.Backhand loop techique is widely used in attack stage and enable the match to be more competitive.(4)The horizontal position loop in using new material table tennis ball has a big difference with that of using celluloid table tennis ball.The competition of backhand loop within is more intense.(5)Backhand loop has a distinct difference between new material table tennis balland celluloid table tennis ball.The change of material and volume of table tennis ball reduce the ball speed.And it also make the hitting point forward and the new competition era of backhand loop technique.Backhand loop technique influences the match trend greatly.(6)The holding plate number of new material table tennis ball varies grealy with that in using celluloid table tennis ball.The rounds in new material table tennis ball increase.The competition of top spinning ball is more intense.During mid rally strokes the score in using new material table tennis ball varies greatly in using celluloid table tennis ball.The stalemate in using new material table tennis ball is more intense and competitive and the most exicting part of the match will be in the second harlf of the match.
