Table tennis has developed to this day. Some of the common equipment used by everyone may not be noticeable, but do you have a deeper understanding of their development history?
Reform of the ball tennis table
The FIFA was established in 1926 and has the world’s first table tennis manual. Table tennis was also called indoor tennis at first. The prototype of its racket was a thread imitation tennis racket, and then she was shot on sheepskin. In 1902, the Europeans invented the rubber shot, covering a layer of single rubber on the wooden shot, and they were all positive glue. The shape of the particles was also strange. At that time, it was found that the rubber shot could make high friction and high rotation, but the height of the net at that time was 19.02 cm and the table was 146.4 cm wide, which limited the offensive means. Later, there were too many defense balls, and it was changed to 15.25 cm high and 152.5 cm wide. The system guaranteed the feasibility of offensive play in the system.
Reform of sponge glue
In 1951, Austrian players added a layer of sponge under the rubber to enhance the flexibility. The world is called “sandwiches”. Unfortunately, the brother’s ball skills are not bad, and the sponge glue failed to attract attention. In 1952, the Japanese Hiroji Satoh shocked four with sponge rubber skills, becoming the first world champion of non -European players, and has since opened the road of sponge rubber. Now that some people have achieved good results with sponge rubber, some people will use them to imitate them. Players of various countries have shot Shanghai cotton to increase their elasticity to get the speed of the ball. Unexpectedly, some people find that the thicker the thickness of the sponge, the greater the elasticity, and the faster the goal, the thicker the sponge on the racket. The famous Japanese player Yoshimoto Yoshiro won the world championship is a very thick layer of sponge but did not cover the rubber.
At this time, there were two voices within the ITTF: prohibited still in favor of sponge rubber. In view of this situation, the International Table Tennis Federation made a regular standard setting for the rubber sponge for the first time. The ping -pong manual in 1959 stipulates that the bottom plate must be wood, the surface coverage (glue) must be granular gel. Whether it is positive or anti -sticker, the total thickness of the sponge cannot exceed 4 mm, and the thickness of the single glue cannot exceed 2 mm.
The start of China’s anti -glue
At that time, most of China used positive glue particles to push left and right to attack. The requirements of the particles were short and large in diameter. After matching the thick sponge, the ball was fast. This is the standard configuration of the positive glue player. With the development of the Japanese arc offensive play, in 1960, the national team appeared in the 8 -person arc team members such as Yu Changchun, Zhou Shusen, and Liu Hengshu. They formed an 8 -person arc circle group. At that time, there was only a manufacturer of Red Shuangxi in China. The rubber supplied was positive glue particles. Obviously, the design of the positive glue particles limited the development of the arc. In order to cater to their play, the national team specially provided them with Japanese -made earth -made anti -glue, and this is the originator of Chinese anti -glue arc. It is difficult to see the Earth’s anti -glue, and it is still the inverted grain (the root of the tooth is small and the top is larger). Later, it was eliminated because the ITTF banned the inverted grain glue.
The collision of the long glue
At that time, there was another milestone event in the national team: the original racer Zhang Yilin also used positive glue. Once in the team, the raw rubber was damaged. There are many adhesives around from time to time to prevent from time to time. In a hurry, the bishop was in a hurry, and the rubber with a long grain made Zhang Yilin posted it. It was surprising that this rubber was originally used for trying to try the anti -glue. Now it has become a positive glue. On the racket of Zhang Yilin, and this glue still has special performance, the opponents get the ball, the more they go back to the ball, the goal will not turn, it will not turn back, Zhang Yilin has found more and more on it. Experience, this created the era of long glue strange balls. From then on, long glue came out and was used by the Chinese team as a secret weapon.
Reform of the same color on both sides
Since the advent of Changjiao, in order to use the two -sided performance but color -like rubber, the inverted technology has also developed to achieve the effect of fully confusing the opponent’s judgment. Although the professional team and even the national team have used long -pair combination of inversion technology, there are very few tricks, but in the 1970s and 1980s, table tennis pouring technology was definitely advanced technology. At that time, Lin Huiqing, Zheng Minzhi, Cai Zhenhua, Chen Xinhua and other athletes all rely on this inverted technology! Among them, Chen Xinhua’s inverted technology was the most honored. At that time, in order to enhance the flexibility of the inverted board, his design of his racket handle was cylindrical, and the shot handles of other athlete rackets were slightly flat. Until 1983, the ITTF stipulated that the two sides of the racket must be different colors. In 1985, it was stipulated that it must be red and black. In 1993, it stipulated that the red surface must be bright red, and since then, the door to the same color racket was completely closed.
Granular glue reform
After the appearance of long glue, due to its unique performance, Europeans are not easy to adapt. In the T4 document of the 1990s, the International Table Tennis Federation stipulated that the positive glue particles include long glue. It is found that this regulation failed to completely suppress the performance of long glue. In the T6 file, the ratio of granular glue to its diameter should not be greater than 1.1, which means that from the perspective of the granularity, the particles are probably square. Therefore, the previous granular granules were not approved by the International Table Tennis Federation. Now the long glue sold on the market is produced in accordance with the new standards.
In 1995, after the Chinese men’s table tennis fought over, a group of positive glue players represented by Liu Guoliang achieved excellent performance. Therefore, the ITTF federation once again shot again, stipulated that the height of the positive glue particles must be greater than 1.0 mm. The speed of pride, this move greatly hurts the positive glue player, so that fewer and fewer people now play the positive glue, and the positive glue near the desk of the Chinese people is less and less. To this day, some old players who are accustomed to positive glue are still pursuing the old -fashioned tradition of positive glue skin, requiring large granules, low height, and 2.3 mm thick sponge on the 12th. The configuration has reached the end of the valuable noise!
What is classic! It is the world. Remember that the anti -glue is the world of Europeans. With the birth of the two major brands of Red Shuangxi and 729, it is represented by PF4 and 729. Chinese players use their own anti -glue! China’s anti -glue is slightly different from the European anti -glue. The biggest difference is the surface stickiness. In order to pursue the rotation effect, Chinese players require the stickiness of the surface of the glue to become higher and higher. The International Table Tennis Federation is the same as China, and the restriction order is launched again: It is stipulated that the light of the surface of the glue should not be measured at a 60 -degree angle spectrometer. Today’s regulations are that the 45 -degree angle light illumination instrument must not be greater than 24 degrees. The stickiness of the rubber is limited, because the greater the light of the rubber during the production process, the stronger the viscosity.
At that time, players with high brightness and strong glue in China did not like to change their rubber casually, so the manufacturer continued to make according to the original process. When testing, you can use your mouth to increase the fog. In the end, at the 2000s of the Sydney Olympic Games, Chinese rubber was measured during training, and it was prohibited from using it, and even if it was corrected, the original model could not be used. Fortunately, Hong Shuangxi Company was in danger. He took out the company’s long -standing registered rubber model Cyclonus 2 and Cyclonus 3. According to the daily requirements of the players, the glue is made, and it was quickly sent to the field. The rubber passed the test smoothly. Very easy to use. The Olympic champion is naturally the Chinese team, and the glue of the Cyclonus series has since begun to have an infinite age!
Reform and reform again, reform and reform
In the 21st century, the ITTFs have made new tricks. In Cantonese, it is: fresh pots in pots. First, the small ball was changed to a big ball. There are two kings and one horses such as a reserve force, and then organic glue to change inorganic glue. I want to reduce the ball speed and weaken the Chinese team. This reform, the two kings and one horse accompanied by the end of the organic era. Mission, Tibetan Mastiff, Dragon, and Python three -legged, carrying the Chinese team!
As the so -called you have Zhang Liangji, I have had a wall ladder, and the manufacturers have become accustomed to changes in rules. As long as there are rules, you can produce equipment that solves the problem accordingly. Based on the slowdown of the ball speed today, manufacturers have made articles on the bottom board and sponge itself. The original organic glue contains raw materials and other raw materials. After infiltrating the sponge, it will have a swelling effect. After the sponge is swollen, it can be fully elastic, and it has always been loved by athletes! After changing to inorganic glue, red doubles, Haifu and other manufacturers came up with the method of expanding the sponge with sponge expansion agent and then brushing inorganic glue. This method is also what we call oil.
Unfortunately, the good times did not last long. Today, the latest measures are to make the sponge in expansion during production. The sponge aperture is large and elastic, so that the athletes can feel the existence of power.
In the 2014 World Cup, Zhang Jike won the first World Cup champion to use the new material ball, which confirmed that no matter how you change your ITTS Federation, the result is that the Chinese team is getting stronger and stronger!
On March 1, 2016, a decision was passed, increasing the height of the net! Intersection It has greatly weakened the quality of serving, adding a lot of difficulty to the fast -down technique of near -Taiwan. The arc circle play will also increase the arc due to the height of the net. The power weakens, the number of rounds is more, and the athlete’s physical fitness requirements are higher.
Each reform of table tennis rules will bring a evolution in equipment. Whether it is a professional athlete or amateur enthusiast, you will feel the charm brought by the development of table tennis in it: the equipment helps us to progress, and we are also promoting the development of equipment!
