Research On The Influence Of The Evolution Of Competition Rules On The Main Techniques Of High-level Table Tennis Players In Recent Twenty Years

The changes in the competition rules have had a profound impact on the development of the world table tennis competition.Since 2000,the table tennis competition rules have changed the small ball to the big ball,the 21-point system has been changed to the 11-point system,the shielded serve has been changed to the uncovered serve,and the organic glue racket The appearance of a series of rules,such as changing to inorganic glue rackets,has greatly improved the appreciation of table tennis and the contingency of game results.After consulting a large number of documents,it is found that in recent years,there have been more unilateral studies on the reform of the above four rules,while the comparison of the above four competition rules at the same time is less.Therefore,this article adopts the method of document data,expert interview,video analysis,and Three-stage analysis,mathematical statistics,logical analysis and other methods are used for research.Representative high-level athletes are selected in the competition to conduct comparative research and analysis of the main techniques before and after the 4 rules reform,and the following conclusions are drawn:1.In the big ball era,the number of rounds in the game has increased,and the speed and rotation of the ball have dropped significantly,which has an impact on the players’ pen-hold serve technique and forehand technique,which weakens the stability of pen-hold serve technique and forehand technique.It is conducive to the development of the splitting technique,which reduces the threat of serving and receiving techniques,and puts forward higher requirements on the basic physical fitness of table tennis players.It is necessary to increase the strength,movement speed,cardiopulmonary endurance,and psychology of the athletes.Aspect training.2.The 11-point competition system affects the basic qualities of athletes’ speed,strength and endurance,speeds up the pace of the game,and needs to quickly enter the game state,which is conducive to forehand high toss and low toss short shots to gain an advantage in the opening game,so that forehands and backhands are pushed.Blocking technology is effectively used,so athletes must switch between offense and defense quickly,especially the speed,which needs to enhance the ability to follow-up.The 11-point system requires athletes to prepare for warm-up activities in advance,and the time and intensity of warm-up activities need to be strengthened.3.The implementation of uncovered serve weakens the traditional way of serving,allowing opponents,spectators and referees to fully see the technique of serving,reducing the advantage of the first three bats,but it is conducive to the combination of reverse pull and looping.After serving,quickly control the rhythm of the game and hit the opponent’s weak side position.It is suitable for the long split technique to improve the quality of the return,and it is conducive to the backhand twisting technique to improve the complexity of the return.The technique of unobstructed serve requires athletes to develop good serving habits,find their own technical means,and better adapt to the rules of the game.4.Inorganic glue rackets affect the focus of the offense and defense of the game,and the overall shift to the stalemate stage,and the utilization rate of the start and grab stages has decreased,and the utilization rate of the stalemate stage has increased.Athletes need to strengthen the corresponding technical and physical training to improve the special events.The importance of skill and strength quality can better adapt to the rhythm of the game.Inorganic glue greatly reduces the toxicity of the racket,reduces the health hazards to athletes,spectators and other participants,and is more in line with the concept of green environmental protection.
