Some knowledge about table tennis

The ball will spin more when looping, but it won't spin when pulling the ball back. These abnormal changes often make the opponent make mistakes or return a high ball, which can often be easily won against people who are not familiar with the properties of long rubber. However, using this rubber to play ball, not only the opponent makes many mistakes, but also it is not easy for his own team to master, which greatly reduces the ornamental and entertainment of table tennis. In May 1998, the ITTF held a board meeting in Durban, South Africa. By 19 votes to 18 votes, it made a decision to ban the use of long rubber and stipulated that the ratio of height to diameter of positive rubber should not be greater than 1:1. Young athletes should never use long glue. On the one hand, long glue is difficult to master, on the other hand, a little carelessness can easily lead to wrong stereotypes. The Chinese Table Tennis Association has clearly stipulated that no long glue should be used in juvenile competitions.

● Anti-arc rubber

There is also a kind of anti-rubber sponge rubber called "Anti-arc rubber" which is specially used to deal with the arc ball. This kind of rubber is non-sticky, with a smooth and slightly astringent surface. The speed of hitting the ball is slow, the arc is short, and it sinks and drifts after landing, making it difficult for opponents to judge according to the routine, which is especially effective to deal with the arc ball. As mentioned earlier, this kind of rubber was pasted on the back of Cai Zhenhua.

In the above-mentioned table tennis racket covers, attention should be paid not only to the selection of rubber properties, but also to the selection of sponges, that is, to the thickness and thinness, hardness and softness of sponges. Generally speaking, the thick sponge eats the ball deeply, bites the ball for a long time, and hits the ball with sufficient stamina, which is more obvious when pulling the ball; On the contrary, the thin sponge eats the ball for a short time, hits the ball quickly and controls the ball well, but the ball has insufficient stamina and is not easy to kill the opponent. As for the hard sponge, it has the characteristics of short biting time and fast ball speed, which is suitable for fast attack; Soft sponges, on the other hand, are inferior in ball speed, but they control the ball better. Generally, people play more smoothly and stably.

In addition to sponge and rubber, glue used to bond sponge rubber also has a very important position in today's high-tech era. A special odorless quick glue can greatly exert its "drug effect" (it is said that it can improve the elasticity of rubber by 2%-3%) before the game, just like giving a racket a stimulant. This wonderful feature was accidentally discovered by Hungarian player KLAMPER. At that time, after he lost a game, he felt that the rubber of his forehand was not well glued, so he posted it again. Unexpectedly, this semi-dry rubber ball made the ball speed improve a lot. Nowadays, it is no secret that instant glue is used, but some people have become too superstitious about its function.

At present, it is not only required that the sponge rubber should comply with the regulations of ITTF, such as the total thickness of the adhesive should not be more than 4 mm, one side of the rubber must be bright red, the other side must be dark black, etc., and the rubber approved by ITTF and the glue used for sticking the rubber must be selected for participating in major competitions. At present, many varieties have been approved in China, and their edges have clearly visible trademark models and ITTF ITIF marks.

my recommendation is to use double-sided reverse rubber sponge as the main material, supplemented by positive rubber sponge on the front and reverse rubber sponge on the back. As an anti-adhesive sponge suitable for both professional athletes and amateurs, it is advisable to choose a type with strong viscosity and moderate elasticity. With the improvement of the understanding of table tennis rotation and the strengthening of ball control ability, in order to obtain the change of the ball, sponge rubber sheets with different properties can be arranged on the forehand and backhand sides. In a word, the choice of rubber, the configuration of positive and negative rubber types must vary from person to person. Qiu Zhonghui, a former world champion, said that table tennis is a sport with a strong "personality", and the types and models of rubber sheets are ever-changing, so we should rationally weigh them from our own conditions and technical characteristics.

The emergence of table tennis is purely accidental. It was caused by two British youths playing. At the end of 19th century, two young people in London went to a restaurant for dinner. While waiting for the waiter to deliver the meal, they were bored, so they took the lid of the cigar in their hands to play with it, and at the same time pulled the cork off the bottle. At the dinner table, they came and went, hitting each other. As a result, they were so fascinated that they even forgot to eat. As a result, this table game quickly evolved into a table tennis match and swept across London, forming a table tennis craze for a while. To commemorate the country that invented it, in 1926, the first World Table Tennis Championship was held in London.

When people played table tennis earlier, most of them liked to stick a layer of leather or cork on the wooden racket. The rubber racket was first invented and used by an Englishman, Goodall. One day, after the game, Goodall went to the drugstore to buy medicine on his way home. When the drugstore owner threw him the change, the coin fell on the rubber plate and bounced. Goode's eyes suddenly lit up, so he bought a rubber plate from the drugstore owner and put it on his racket, carefully reforming his original racket. Later, Goode entered the competition with the world's first rubber-coated racket, and easily defeated all his opponents. Since then, the rubber racket has been made public.

The origin of the name of table tennis and others

In the history of sports, table tennis can be regarded as a young sport, with a history of only over 1 years. Compared with track and field (more than 2, years), it can be regarded as a veritable junior.

in p>189, several navy officers stationed in India happened to find it exciting to play tennis on a small table. Later, they used a small hollow ball instead of a solid ball with little elasticity, and used a wooden board instead of a racquet to play this novel "tennis match" on the table, which is the origin of the name table tennis.

soon after its appearance, Table Tennis became a popular sport. At the beginning of the 2th century, the United States began to produce complete sets of table tennis equipment. Initially, table tennis had other names, such as Indoor tennis. Later, an American manufacturer coined the new word ping-pong with the sound made by ping-pong when it hit, and used it as the registered trademark of his "ping-pong" patent. Ping-pong later became another official name of table tennis. When it spread to China, people coined the new word "table tennis".

in Japanese, table tennis is called "table tennis". Many words in table tennis are derived from tennis. The ball used in table tennis is called ping-pong ball or table-tennis ball, the table tennis table is called ping-pong table, the table top is called court, the net in the middle is called NET, and the shelf supporting the net is called net support.

table tennis singles usually adopt the best of three games or the best of five games system, which is called "game" and is set in English. Serve is called serve.

table tennis originated in Britain. Europeans have called it "tennis on the table" so far. It can be seen that table tennis developed from tennis. At the end of 19th century, tennis was popular in Europe. However, due to the limitation of space and weather, some college students in Britain moved tennis indoors, using the dining table as a table, books as a net, parchment as a racket and playing it around at the dining table.

At the beginning of 2th century, Table tennis flourished in Europe and Asia. In 1926, an international table tennis invitational tournament was held in Berlin, Germany. Later, it was regarded as the first world table tennis championship. At the same time, the International Table Tennis Federation was established.

The extensive development of table tennis has greatly improved the racket and the ball. The original racket was a slightly processed board. Later, someone put a layer of sheepskin on the racket. With the development of modern industry, Europeans put rubber with rubber particles on rackets. In the early 195s, the Japanese invented rackets with thick sponges. The original balls were rubber balls similar to tennis. In 189, British athlete Gibb brought back some celluloid balls as toys from the United States for table tennis.

Among various table tennis competitions, the most famous one was the World Table Tennis Championships, which was held once a year at first. After 1957, it was held biennially.

In p>194, Wang Daowu, the owner of a stationery store in Shanghai, bought 1 sets of table tennis equipment from Japan. Since then, table tennis has been introduced to China.

Table tennis originated in Britain at the end of the 19th century, and then spread to the United States, central Europe, Japan, China and South Korea. At first, table tennis was regarded as an entertainment activity by many people, but up to now, it has become one of the major sports in the world. Table tennis was recognized by the Olympic Games in 1988 and officially became a competition, including men's singles, women's singles, men's doubles and women's doubles.
