What is our national ball?

Of course, it is one of table tennis and ball games. It is conducted on a table with a horizontal net in the middle, which is 274 cm long and 5 cm wide. 152. The diameter of the ball is 40.00 mm and the weight is 2, 40-2 and 53 grams. It is white or yellow, made of celluloid or plastic, and has a ping-pong sound when playing, hence the name. The player stood on one side of the table and hit the ball with a racket. The hitting methods are blocking, drawing, cutting, rubbing and pulling. The ball must bounce off the stage before it can return to the net. It is effective to leave it on the other side's table. The game is divided into one game with 1 1, and the best of three games or the best of five games is adopted. There are several kinds of competitions, such as team competition, singles and doubles. Table tennis originated in England at the end of19th century. It started as an active game. This ball is made of light and elastic material. A wooden board like a cigar box cover hits the table like tennis, so it is called "table tennis". 1900 or so, due to the development of light industry, the ball was changed into a hollow ball made of celluloid. Since then, table tennis has gradually developed. The first large-scale table tennis competition was held in February 1900 in London, England. More than 300 people took part in the competition. During the competition, male athletes should wear shirts and starched vests, while female athletes should wear skirts and even hats. 1926, the International Table Tennis Federation was formally established and decided to hold the first World Table Tennis Championships. In the past 50 years, the development of table tennis has gone through three stages. Although the rackets used by early athletes have different shapes, they are all made of wood, and the hitting speed is slow. Small strength, not to mention any rotation; The play is monotonous, just pushing the ball around. 1903, an Englishman Goodall invented the rubber racket, which strongly promoted the development of table tennis technology. From 1926 to 195 1, most players around the world use rubber bats with cylindrical particles on their surfaces. When hitting the ball, the elasticity and friction increase, which can make the ball rotate to a certain extent, so the defensive style of cutting off the rotating ball appears. This style of play has been popular in Europe for a long time, and many athletes have won the world championship with this style of play. The advantage of table tennis in this period was in Europe, among which Hungary scored the most outstanding. 1 17 world champions won 57 or 5 times, accounting for half of the European team. In the early 1950s, the Austrian invented the sponge racket, and the Japanese athletes' morality was used in world competitions, winning four championships in the 19 World Championships in one fell swoop, breaking the monopoly position of European athletes. Because Japanese players used this racket to create a long-range attack style, which has the advantages of strong forehand attack, fast speed and great threat of serve attack, it gradually replaced the defensive style of slow speed, weak rotation and weak attack in Europe, which made Japan win the advantage of table tennis in the 1950 s. From 1952 to 1959, Japan won 24 of the 49 world championships. This is the first big improvement in table tennis. From 65438 to 0959, after Rong Guotuan won the men's singles championship in the 25th World Table Tennis Championships, China athletes began to enter the international table tennis arena. Gradually formed a "fast, accurate, ruthless, changing" technical style of the fast-break style. In the 26th World Championships of 196 1, China not only broke through Europe, but also defeated the Japanese player who won the secret weapon-"curling ball" and won the men's team world championship for the first time. And won the 27th and 28th men's team championships in succession. The advantage of China's near-table fast break is its close position, high speed, flexible action and free use of forehand and backhand, which is a great progress compared with Japanese long-distance draw. In 1960s, China's table tennis skills were in the forefront of the world, and its advantages were transferred from Japan to China. This is the second big improvement in table tennis. With the development of table tennis in Japan and China, European athletes have learned from their failures. After nearly 20 years of hard work, they finally created an advanced style of play that suits them, that is, the combination of loop ball and fast break. The representative figures are Hungarian Crampa and Jonel. The combination of fast break and loop ball is based on forehand and backhand fast break as the main technique, backhand fast break as the initiative and forehand loop ball as the scoring means. Representative figures are Gehlsen of Sweden and Olovsky of Czech Republic. These two styles of play are characterized by strong landing point, fast speed, strong pulling and hitting ability, low pulling and high hitting, and large room for manoeuvre. Table tennis has developed to a new height, and its position and speed are closely combined. This is the third big improvement in table tennis. Since 1970s, due to the strengthening of international exchange and study, various styles of play complement each other, which makes the development and improvement of table tennis technology faster. For example, China's near-table fast break, straight-shot fast break combined with loop ball, and horizontal-shot fast break combined with loop ball have all developed and innovated, and achieved excellent results in international competitions. Now, table tennis has developed into one of the favorite sports of people all over the world. The International Table Tennis Federation also has 127 member associations/one of the largest sports organizations in the world. ITTF and table tennis federations of all continents have organized numerous world championships, World Cups, intercontinental competitions and international competitions of all sizes and forms. From 1982 to 1988, the decision of the international Olympic Committee to list table tennis as an official Olympic event will surely attract more attention from all countries in the world and promote the faster development of table tennis. The origin of table tennis and other names in the history of sports, table tennis can be regarded as a young sport with a history of only 100 years. Compared with track and field (more than 2000 years), it is also a veritable junior. 1890, several naval officers stationed in India came across that playing tennis on a small table was quite exciting. Later, they used a small hollow ball instead of a solid ball with little elasticity and a wooden board instead of a racket to play this novel "tennis match" on the table, which is the origin of the name table tennis.

The extensive development of table tennis has promoted the great progress of rackets and balls. The original racket was a slightly processed board. Then 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 1950s, the Japanese invented the thick sponge racket. The original ball was a rubber ball similar to tennis. 1890, British athlete Gibb brought back some celluloid balls from America as table tennis toys. Among all kinds of table tennis competitions, the most famous is the World Table Tennis Championships, which was held once a year at first.
