What is the function of the red and black sides of table tennis rackets?

For Japanese pen-hold shooting, the front side is red, and the back side must be painted black (the front side is black, the back side is red) to distinguish it, and it is non-reflective. This is a regulation of the International Table Tennis Federation (ITTF).

The International Table Tennis Federation (ITTF) technical manual stipulates that the thickness of the rubber must not exceed 4.0mm, and the color of the rubber can only be red and black. It also stipulates that if the rubber on one side of the racket is red, the other side must is black.

When table tennis developed into the 1950s, many people thought that the pattern of this sport was set. , there won’t be any big changes. However, in the next 40 years, the players found four treasures by chance - sponge, long glue, anti-arc glue and fast glue. The emergence of table tennis "changed beyond recognition", forcing the ITTF to It has been revised and restructured many times. So I personally think that these are the "four great inventions" in the history of modern table tennis. Here I will tell you four short stories collected by the author. Of course, there is some humor in them, believe it or not.

It’s all opportunities

In March 1951, the 18th World Table Tennis Championships was held at the Vienna Concertgebouw. During the fierce battle, the famous French player Rousseau could only be heard complaining: "The ball passed without even hearing the sound." Hungarian main player Joseph Gokian (his sister fought 500 rounds with Qiu Zhonghui in Beijing ten years later) shouted angrily: " This trick should be banned!" Their opponent was the little-known Austrian college student Waldemar Fritsch. With a sponge racket that people have never seen before, Foric has repeatedly made extraordinary achievements for the Austrian team: against Hungary, he defeated Sido and Gaukian; against France, he defeated Hagenauer and others, scoring three points... 32 singles At 16, he fought hard for several rounds with Harangozo, the top player from Yugoslavia, and after knocking his opponent off the ring, the coach said to him, "My left eye was full of tears of happiness, but my right eye was full of sadness." It turns out that his coach is Harangozo’s eldest brother. However, when 16 advanced to 8, Xiduo, who had been fooled once, did not give him another chance. No one expected at the time that this game would be Foric’s first appearance at the World Table Tennis Championships and also his last world competition. Years later, when he was asked about it, Mr. Forich said, "It was all opportunity."

It turns out that Mr. Fu served in the Nazi army during World War II and was captured by the Soviet Red Army. After being released home, he re-entered university. He is an all-rounder in sports. After school, he spends all his time in sports, such as table tennis, football, handball, track and field, swimming, gymnastics... he is good at everything. In early 1951, he went to the club to play table tennis and met a comrade who had been captured by the US military. The man saw that he didn't have a racket, so he gave him one of his old rackets. This racket was really old and the rubber was peeling off. However, supplies were tight in Europe after the war and new rubber could not be purchased. So Mr. Fu found an old black sponge and stuck it on. The effect was extraordinary after he tried it. After practicing hard for more than a month, he joined the Austrian national team. Under the careful guidance of the coach, he practiced skillfully for another four weeks, and he achieved the scene above. After the World Table Tennis Championships, Foric's confidence doubled, he put his homework aside and concentrated on practicing the ball. But on the eve of the World Table Tennis Championships in Mumbai the next year, he learned from the radio that Austria only sent two officials and two female players to participate. Furtsch was so angry that he quit auctioning. He later earned a doctorate in political science and became a director of an insurance company.

Mr. Fu's opportunity for table tennis in just over a year has plunged table tennis into chaos. According to the memory of Mr. Ichiro Ogimura, the former chairman of the ITTF, when he won the world championship for the first time in 1954, the racket was initially made of 8~10mm thick sponge (without rubber), which was like a sofa cushion. Later, he felt that it was difficult to control. , 8 into 4, I changed to 3mm sponge and used it until the finals.

In one match, there was such a big difference between the rackets used before and after. Although it shows that Mr. Ogimura has profound skills, his success was only possible under the background of chaotic equipment at that time. What Europeans and Americans initially thought was how to ban this kind of sponge racquet, but the shrewd Japanese introduced it and developed a yellow soft sponge racquet. As a result, they became the table tennis overlord in the 1950s. The debate about sponge rackets did not come to an end until the ITTF made a standardization decision in 1959, and the world of modern table tennis was thus created.

The gods shocked everyone

The spring of 1961 was the most bleak day in modern Chinese history. We Longcun people survive by eating a kind of milky white mud called "Guanyin soil" from the mountains. It was during this period that one day, Zhang Xielin received a piece of rubber, a piece of unqualified rubber, a piece of rubber with extra long teeth and small holes on the surface! If it had been any other time, this waste product would have ended up in the garbage dump before it left the factory and would not have reached Zhang Xielin's hands. But in special times, Zhang Xielin, who has always been diligent and thrifty, would not think of the word "throw". Even if I think about throwing it away, I am afraid of being caught as a "typical"; even if I am not afraid of being caught, I am still afraid of making a fuss about "Why don't I eat meat porridge" like Qiu Zhonghui asked the leaf picker "Can this be eaten?" So he put this piece of rubber on and tried it, but it turned out that it was too awkward to fight, and his opponent felt very uncomfortable and was unwilling to spar with him. Lao Zhang's heart brightened: "If I try my best to endure hardship, I will feel uncomfortable enough first and it will become a habit. Isn't it just the other party who will feel uncomfortable?"

Two years later, "Zhang Xielin's God-given Shock" came out and shocked everyone. "The play was staged in Prague. Among the foreign masters, almost no one can score more than 10 points in a game in his hands! The ball he chipped went out of bounds as soon as he pulled it; the ball he blocked went out of the net as soon as he hit it. There was neither applause nor boos. The audience had their mouths open and they were really "dumbfounded"! This is a Prague audience, a Czech audience! In history, the table tennis exhibition match with the largest audience took place in the Czech Republic in the early 1950s, with more than 50,000 people! Of course, it was just an "appetizer platter" before a high-level basketball exhibition game, but what Uncle Sam's family is now serving Jordan and Yao Ming as appetizers are beauties in exceptionally cool clothes, which shows how "beautiful and delicious" table tennis was in the Czech Republic back then. To listen to concerts, you have to go to Austria; to watch table tennis, you have to go to the Czech Republic and Yugoslavia. Therefore, the word "surprise" here has the effect of "knock" in the ancient "Monk knocks on the door under the moon".

The audience was stunned, and the Chinese game commentator was also stunned! I couldn't find words to describe it, so I said Zhang Xielin's save was like "fishing for the moon under the sea". Once he said this, he couldn't catch any horse, and he kept saying it for 40 years. This author has not dared to raise a voice for many years because he was afraid that if he said something wrong and would be laughed at as being ignorant, I would like to ask everyone to help blend it in: Is this "fishing for the moon under the sea"? Why do all the scenes I see show "touching turtles in a jar"? Of course, this is beside the point.

Since then, Zhang Xielin has been known as the "Magician". Another two years later, the magic was deciphered. At the 28th World Table Tennis Championships, after 8 points and 4 points, after more than two hours of five rounds of slicing battle, he was finally eliminated by West Germany's Sauler.

Liang Geliang was the first to become famous for using long glue, which finally alerted Premier Zhou Enlai to intervene. The one with the longest particles is said to be Ge Xinai, who came to the rescue twice (33rd group, 35th singles) when the first main player Zhang Li fell. The Chinese team lost the men's and women's team championship in the 32nd session, and happened to have no rubber. So in Birmingham in 1977, a reporter asked, "Does the Chinese team rely on rackets to win?" Li Furong replied, "It is people, not things, that determine victory or defeat." This is natural. Huang Liang is the only one in the world who still feels aggrieved by spinning the ball with his long rubber hair and making Krampal eat five in a row. However, among our "Five Tiger Generals" at that time, there were three who played long-term rubber. The long rubber cover is difficult to practice and becomes completely passive after being deciphered. It is basically a "disposable" weapon, so Chinese players use it the most. Therefore, the ITTF has revised its rules many times to impose restrictions on long rubber. There are many reasons for the decline of table tennis. The "secret weapon" is difficult for ordinary audiences to understand. The author believes that it should be one of them.

The credit of the sun

At the 31st World Table Tennis Championships in Nagoya in 1971, an unknown French player Jean Paul Weber (also translated as Weber) He shined brightly, defeating famous players such as Bengtsen and Xi Enting, and contributed greatly to the French team's seventh place in the team. His unique shot attracted people's attention.

Mr. Weber is still teaching golf to this day. Mr. John Schneider of tabletennis.about.com in the United States found the website of Mr. Weber’s club. There is an explanation: Once after Mr. Weber glued the racket, he put it on the window sill and forgot to put it away. I didn’t think about it until I played ball at night. It looked like the rubber had been burned, but it was too late to re-glue it, so I had to use this racket. Unexpectedly, the effect was so good that he went to the 31st World Table Tennis Championships as the "secret weapon" of the French team. From then on, the anti-arc rubber was born.

The famous foreign players who used anti-arc rubber from the 1970s to the 1980s include Hungary's Brzisser, the Simile brothers and the Bogen brothers of the American team, and the English weirdo Hilton, etc. Although they They all made small achievements, but they did not have a particularly big impact. Instead, Cai Zhenhua used arc-proof rubber to the extreme. With a clear mind and flexible wrists, he combined Liang Geliang's stomping serve with Hilton's false loop, and added the word "quick". The opponent didn't have time to see the looping ball he pulled, so he could only guess whether it was real or fake. If he got it wrong, he would make a mistake. For example, if you block a non-spin ball as a strong topspin ball, it will go down the net. Therefore, you must catch his serve faster and more actively than receiving other people's serves, and try to avoid being overtaken by him and falling into the trap of his serve. Want to know how powerful Cai Zhenhua’s serve is? Let me give you an example: Cai Zhenhua played against Gayle Gay in Game 6 of the 36th World Table Tennis Championships Men's Team Finals in 1981. After each team won one game, the third game ended in a tie at 15. The big score at this time is that the Chinese team leads 3:2. If Cai Zhenhua wins this set, the score will be 4:2. In the seventh set, Xiesek will be unstoppable against Krampal, who is accustomed to hitting downwind balls. On the contrary, the score was 3:3. Not only was Xiesek difficult to beat, but Shi Zhihao, who had lost two sets, was at a disadvantage against Gergei. In the end, Cai Zhenhua also had to beat Yonier, who was unable to serve well. The outcome was difficult to say. At this critical moment when he had to win, Xiao Cai showed off his unique serve and fed Gale Guy 5 times in a row! It can be said that these 5 serves determine the outcome of the entire game.

After the 36th World Table Tennis Championships, various schools and factions stepped up their research on Cai Qiu. Many papers have been published, but there are no effective methods. Different from the long rubber, the true and false loop shots are proactive and the speed is much faster and there is no time to judge. Not only can outsiders not break it, but even the brothers who have practiced together for many years are not easy to deal with. It is said that at that time, he won the most in the internal training competitions between his fellow disciples. Therefore, the ITTF made a decision after the 37th World Table Tennis Championships in Tokyo in 1983 that the colors on both sides of the table tennis racket must have a sufficiently large contrast. Later, the "enough contrast" was changed to red and black. In the 38th World Table Tennis Championships in 1985, Cai Zhenhua only participated in doubles and won the mixed doubles championship with Cao Yanhua. Subsequently, a large number of 23- and 24-year-old world champions such as Cai Zhenhua, Xie Saike, Cao Yanhua, Qi Baoxiang, and Ni Xialian retired, kicking off the "Wolf Crying" drama in China's table tennis.

The author used to have a sense of mystery about anti-arc rubber. I've seen two types of basketball recently. The surface of one feels like fine sand, and the elasticity of the sponge is similar to that of anti-glue, so the ball pulled out will spin very weakly; the surface of the other type is reflective, and the elasticity of the sponge is poor, so it will naturally reduce force when used to block the ball. True and old The rubber is somewhat similar. It is said that the old rubber was used when Sarkhoyang of the Soviet Union eliminated Xu Shaofa at the 32nd World Table Tennis Championships (formerly). No matter what kind of anti-arc knife it is, if it is used on both sides, it is probably impossible to hit the ball. Therefore, the story about Bolzisai using a double-sided anti-arc knife to defeat Xi Enting is probably a rumor.

The Discovery of the Prodigal Son

The influence of quick glue on modern table tennis is well known. On our table tennis home (ttball.net), some netizens said, "If I don't use glue, I won't be able to play." On the American table tennis website, someone said, "Glue will help me gain at least 50 points of skill." So what’s the secret to quick glue, and where does it come from?

It is generally believed that the secret of quick glue is that its volatile gas fills the pores of the sponge, causing the sponge to expand in volume and increase elasticity, while the degree of control does not change much. This principle still needs to be confirmed by more detailed research. I would like to talk about my understanding of its origin here.

The first time I heard about the role of glue was during the summer vacation of 1975. Two table tennis classes from the Jianghan District Sports School in Wuhan City came to our place to "open their doors", but they "acted against Chairman Mao's instructions" to "eat, live and work together" - they lived in our school and did not He was willing to train with us, saying he was afraid that we would "lead the children bad."

The other members of our school's table tennis team were all "wooden sailboats that couldn't withstand a cannonball", so I thought they were afraid of me and were very proud of me, often provoking others. In the end, I offended a child who was not afraid and flattened me nine times while their teacher was away. Although there were two 20 draws, I never won a game.

After playing football, we went to the experimental field of the Institute of Agricultural Sciences, pulled out some "ton and a half" rice ears that had just been grouted, and burned them outside the school wall where the bad students smoked. The two of us had eaten it several times, and the yield of this excellent variety, which was 3,000 jin per acre, became 2,990 jin, so it was not popularized later. After eating the grain, he helped me analyze the reasons for the loss: poor basic skills and poor continuous offensive ability were the main factors, and there was also a secondary factor: "the racket was too bad."

"Yours is Double Happiness, and mine is also Double Happiness, so what the hell is wrong?"

"My Double Happiness is professional. You don't know, when the rubber is newly applied, , It’s so good. If you don’t believe it, try it.”

I took it and looked at it. His racket was heavier, darker, and had a thicker blade, while mine had a seven-clip blade. It's five clips, but the rubber is the same.

"Then let me try it. If it is really good, please help me buy one in Wuhan."

"I can't buy it. Our teacher got it from the province." "

As soon as I heard this, I quickly returned the racket to him, for fear that I would not be able to pay for it if it was damaged. But the words "new rubber is easy to beat" are as delicious as new rice, and I will remember it for a lifetime. Whenever someone tells me that quick glue is a European invention, I will say, "Nonsense. That is the gunpowder in our hometown. I knew it when I was a kid." However, later I saw that Cai Zhenhua was obsessed with sticking glue. When reporting on the punishment of Ma Wenge, I was full of doubts again, "Is it the same as hitting the back of the straight, something that even a kid knows, but the national team doesn't know?"

This mystery was finally revealed by Krampa last year Mr. Er untied it when he visited the ITTF website. Lao Ke said that when he was a little kid, he liked to hear the "bang bang" sound of newly put rubber on the ball when playing ball. When playing ball with his brother, he would re-attach the rubber every time. One time I didn't stick to it, and I lost miserably. Therefore, after he became a professional golfer, he cooperated with equipment manufacturers and successfully developed quick glue.

It is not difficult to find out that the new rubber is easier to hit, and both Chinese and foreign kids know it. But the purpose of the Chinese little boy wearing rubber is to repair his racket or replace it with new rubber. For things that are intact, they are afraid of being "broken." Therefore, before every round of playing, first make the "good" racket "bad", and then engage in the "good" and "prodigal" behavior. Only Krampal, who is considered a "bad" among foreigners, would think of it. .
