(2) Must-answer questions

1. What improvements have table tennis rackets and balls undergone?

("Small ball" becomes "Big ball"

In the early 1980s, after the Chinese team won 7 championships in the 36th World Table Tennis Championships, some people Suggestions were made to make the table tennis balls larger and the nets higher, but this suggestion was not taken seriously.

Since then, table tennis technology has continued to develop, and the ball speed has become faster and faster, and the spin has become stronger and stronger. . Many athletes have fewer rounds when playing against each other; sometimes the ball flies like lightning, and the winner has been decided before the audience can see it clearly, which weakens the interest of table tennis enthusiasts. For this reason, the former chairman of the ITTF, Ogimura Ichiro, once considered table tennis. The ball increased. Xu Yinsheng put this matter on the agenda after he became the chairman of the ITTF.

In May 1996, the ITTF Board of Directors agreed to the proposal to experiment with larger balls - in order to slow down the speed and rotation of the ball, increase the round and ornamental value, it was recommended to increase the diameter of the table tennis ball by two millimeters. The ITTF planned to conduct a trial at the Youth Championship in Japan the following year, but gave up because the Japanese manufacturers had too many objections. At that time, changing the size of the balls was just a suggestion. If manufacturers wanted to produce larger balls, they would need to invest money to remake the molds and adjust the process. If the suggestion was ultimately rejected, the money would have been 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 batch of high-quality balls as required, which were given to member associations by the ITTF for trial use. The China Table Tennis Association, the only company in the world that has instruments for measuring dynamic table tennis speed and rotation, took the initiative to undertake the testing work. Researchers from the Scientific Committee of the Chinese Table Tennis Association conducted "experiments on the effects of table tennis balls of different diameters and weights on batting speed and spin." The experimental conclusion is: a ball with a large diameter is slower than a ball with a small diameter, and its rotation is weaker than a ball with a small diameter; for balls with the same diameter, the ball with greater weight and elasticity is faster and has stronger rotation than the ball with smaller weight and elasticity.

The first test of a big ball was held during the 44th World Table Tennis Championships in 1997, but it had little impact. In the spring of 1998, the Suzhou International Table Tennis "Big Ball" competition proposed by Xu Yinsheng conducted its second trial. The Chinese Table Tennis Association took the initiative to bear the funds for the Suzhou trial competition. In 1999, another international competition using the big ball was held in Copenhagen, Denmark.

At the ITTF Congress held during the 45th World Table Tennis Championships in Dawei in 1999, the "Big Ball Reform" proposal was shelved because it did not receive a three-quarters majority vote. 84 of the 124 members voted in favor, 30 opposed and 10 abstained. The then newly appointed ITTF President Shalala said that some representatives abstained or voted against the vote because they did not understand the impact of this reform measure, and he would do the work of explanation and persuasion.

On February 23, 2000, the ITTF Special Conference and Congress passed the 40 mm ball reform plan in Kuala Lumpur and decided that from October 1, 2000, that is, after the Sydney Olympics, table tennis The ball game will use large balls with a diameter of 40 mm and a weight of 2.7 grams to replace the small 38 mm balls.

In addition, the reforms of table tennis also include "implementing the '11-point system' to replace the '21-point system'" and "unobstructed serving." The "glue ban" was officially implemented on September 1, 2008, and inorganic glue was used instead. Solvent glue with volatile substances is usually called organic glue or quick-drying glue. Its main components are adhesive colloid and organic solvent. The latter refers to a low-toxic, volatile chemical solvent that can dissolve adhesive colloid, which contains toluene, Xylene and other toxic ingredients, the ITTF has certain restrictions on toxic ingredients in glue. Organic glue can increase the elasticity of the sponge and increase the speed of the bat. Every athlete needs to apply glue to the racket several times before participating in the competition. This is also regarded as an essential weapon in table tennis competitions. Inorganic glue is colorless and odorless. The dilution is similar to water. It does not increase the elasticity of the sponge. It only needs to be brushed once. The base plate of this glue is easy to clean without leaving any residue. )
