The Influence Of The Application Of New Plastic Ball On Table Tennis Training And The Improvement Measure

2014 ITTF to replace the new table tennis rules,the use of new plastic material table tennis instead of the previous celluloid material table tennis,on this basis,the ITTF given two years,so that the world's athletes to adapt to the new Plastic ball,in2016 the new plastic ball officially became the official designated ball,which means that the celluloid material ball out of the table tennis project,the new plastic ball officially appeared in the stage of the game.This paper mainly uses: the common search literature,invites experts to make experimental analysis,image analysis and mechanical analysis and other methods of new plastic ball and celluloid ball flight,rebound and hit the ball and other data analysis.Using the mechanics analysis to establish the mathematical model,the flight of the new plastic ball and the celluloid ball is analyzed and described.Under the same condition simulation,the new material plastic table tennis flight and the rebound stability are better than the celluloid table tennis ball,but in the The minimum force hit two kinds of table tennis when the celluloid table tennis mechanics rebound performance appears drop angle vertical angle,and with the flight arc irregular phenomenon,the new plastic table tennis in the small force hit the rebound when the angle of decline and smooth Arc and so on better than celluloid ball.The flight of the new plastic ball tends to be closer to the net,and the experiment proves that the rebound strength of the new plastic ball is reduced.The quality of the plastic ball is better than that of the celluloid ball.Not jump forward,there is no significant difference between the rise and high point flight,the angle difference between the obvious difference,the new plastic ball falling faster,while the flight distance is shorter than the celluloid table tennis.Athletes hit different materials table tennis image and mechanics analysis,the new plastic ball flying distance is short,the drop speed is greater than the celluloid material table tennis,the athletes hit the new plastic table tennis when the initiative to move forward,with the striking power of the constant Zhengda,the new plastic ball flying far no celluloid ball changes,strength and distance is not a positive correlation.For different characteristics,the grass-roots table tennis training to increase the swing force of the special practice,multi-ball practice coaches always prompt athletes to move forward.Continuous forehand arc ball practice to increase the batting force,before the increase in the amount of training before the hit.Through these two points also require athletes body strength,special physical needs need to be strengthened.For the technical and tactical aspects can no longeradvocate the 'first three board',because the new plastic ball material changes on the hands of the action of the arc,speed and other aspects of the impact of these effects led to the athlete to receive the ball attack rate decreased,the use of Rate is also lower than the celluloid ball.In the serve siege and stalemate in the link,the impact on the athletes is relatively small,due to the new plastic ball hit the arc when the small arc and angle is better than the celluloid ball,making the players in the use of short ball more difficult,The use of more difficult,the overall tactical system from the era of celluloid ball,far from Taiwan to close,the trend of change in the Taiwan offensive.
