Reform of table tennis from "small ball" to "big ball"
In the early 1980s, after the China team won seven championships in the 36th World Table Tennis Championships, some people put forward the suggestion of increasing table tennis and nets, but this suggestion didn't get people's attention.
Since then, the technology of table tennis has been developing continuously, and the ball speed is getting faster and faster, and the rotation is getting stronger and stronger. Many athletes have fewer rounds against each other; Sometimes the ball flies like lightning before the audience can see it clearly, and the outcome has been decided, which weakens the interest of table tennis fans. Therefore, Ichiro Okimura, former president of ITTF, once considered increasing table tennis events. As the president of ITTF, Xu Yinsheng put this matter on the agenda.
1in may, 996, ITTF parliament agreed to the proposal of testing big ball &; In order to slow down the speed and rotation of the ball and increase roundness and appreciation, it is suggested to increase the diameter of table tennis by two millimeters. ITTF is going to do an experiment in the youth championship in Japan next year, but Japanese manufacturers gave up because of too much opinion. At that time, I just suggested changing a big ball. In order to produce big balls, manufacturers need to invest money to remake molds and adjust the process. If the proposal is finally rejected, the money will be wasted.
In order to support the reform of table tennis, Shanghai Double Happiness Table Tennis Group resolutely undertook the trial-production task, and produced a number of high-quality big balls as required, which were sent to member associations for trial use by ITTF. The only table tennis association in the world that has instruments to measure the speed and rotation of dynamic table tennis has taken the initiative to undertake the testing work. Researchers from the Scientific Committee of the Chinese Table Tennis Association made an experiment on the influence of table tennis with different diameters and weights on hitting speed and rotation. The experimental conclusions are as follows: the ball with large diameter is slower than the ball with small diameter, and the rotation is weaker than the ball with small diameter; For balls with the same diameter, a ball with large weight and elasticity is faster and more powerful than a ball with small weight and elasticity.
1997 During the 44th World Table Tennis Championships, the first big ball test was conducted, but it had little impact. 1In the spring of 998, the Suzhou International Table Tennis "Big Ball" competition proposed by Xu Yinsheng was tested for the second time. The Chinese Table Tennis Association took the initiative to undertake the funding for the Suzhou trials. 1999, another international competition was held in Copenhagen, Denmark, using big balls.
1999 At the ITTF Congress held during the 45th World Table Tennis Championships in Dawei, the proposal of "Big Ball Reform" was shelved because it did not get a three-quarters majority. Of the members of 124, 84 voted for it, 30 opposed it, and 10 abstained. Shalala, then the new president of ITTF, said that some delegates abstained or voted against the reform because they didn't understand the impact of the reform, and he would explain and convince them.
On February 23rd, 2000, ITTF Special Congress and Congress adopted the reform plan of 40mm big ball in Kuala Lumpur, and decided to start with 65438+ 10/in June, 2000, that is, after the Sydney Olympic Games, the big ball with a diameter of 40mm and a weight of 2. The table tennis match will use 7g instead of 38mm balls.
At present, China Double Happiness and Pisces have developed seamless table tennis, which uses a whole piece of material to make the ball more durable. This new ball will be popularized after the London Olympic Games.
In addition, the reform of table tennis also includes "implementing &; Lsquo 1 1 system &; Rsquo replacement &; lsquo； 2 1 system &; Rsquo "and" open serve ". From September 1 2008, the "glue ban order" was officially implemented and inorganic glue was used instead. Solvent glue with volatiles is usually called organic glue or dry glue. Its main components are viscous colloid and organic solvent. The latter refers to a chemical solvent with low toxicity and poor volatility, which can dissolve adhesive colloid and contain toxic components such as toluene and xylene. ITTF has certain restrictions on toxic components in glue. Organic glue can increase the elasticity of sponge and improve the hitting speed. Every athlete needs to brush his racket with glue several times before the competition, which is also regarded as an indispensable weapon in table tennis. Inorganic glue is colorless and tasteless, and its dilution is similar to that of water, which will not increase the elasticity of sponge. It only needs to be brushed once, and the bottom plate of this glue is easy to clean without leaving any residue.
