The configuration of hitting the ball and racket
Table tennis is a highly athletic technology, and its complexity is mainly manifested in the diversity of winning factors. In terms of speed, the strength of the ball, the rotation speed and the position of the arc trajectory length can be one of the factors. The winning opponent is in a difficult situation. It is difficult to judge, move and control the ball without mentioning all the winning ways in front of others. The reason is a complicated state, in a sense, because our rackets and operations use different lenses to choose different configurations. There is a subtle relationship between users and devices. This is a kind of play with the front sponge racket, which creates a table-top fast attack play close to it, and the rubber-proof sponge racket creates a racket with a fast loop ball attack play and creates a new play. However, a different user, using the same type of racket in this process, can change some configurations to create different "stunts".
Zhuang Zedong, Qiu Zhonghui and Xu Yinsheng, who can't take the initiative to play sponge, are close to the first generation of table tennis in China. They can make a beat or break it. However, when Rong made his first start after the loss of resources and the Hungarian veteran Sido, he boldly changed his routine and took out his active sponge racket to increase friction and destroy the opponent's rhythm, so the winner in the west did nothing. Finally, at the 25th World Table Tennis Championships, the people of China won the world championship. His famous saying "There are several strokes in the first dream of life" spread like wildfire and spread all over China. As we all know, Zhuang Zedong's choice is the reverse sponge. More importantly, this kind of racket and sponge has the unique characteristics of projectile launching power, and the pen keeps a rapid breakthrough on both sides of the strait. "Little Tiger style, along with. According to the linear thinking mode, someone suggested that he change the hardness of a sponge to further increase the attack speed. The result does not prove that this is a "despicable trick";
China's first flower racket was stamped back to Hongkong, and Jiang Yongning, in the face of vigorous crushing, his domestic monthly is a must. However, Zhang, who really played the backhand with "Magician", was inspired by an unexpected "long rubber stroke" and "anti-rotation". In fact, cutting the ball has become a "rotating" downward rotation push file, but it can cut the loop ball, and it may even become more and more incredible. In order to keep this "secret" game world, shooting for his other ordinary rubber (no racket detection system) is to see his racket make this common, and the only long rubber racket in this game should be put into the bag immediately after the game, so it is not necessary to "reveal" the name of a "magician" to really realize it. The Liang Geliang Tongfang long rubber racket invented by the former world champion has created a lot of serve opportunities in order to make full use of the huge gap between different front-reverse rubber and rubber back lengths (the color of the racket face is not limited) and the same action. Many famous games, he has no choice. Remember, in the national competition, he only lost one game. He was a veteran of the Guangdong team when he won. Everyone runs around and tends to "learn" the truly amazing but successful miracle: "Don't serve, stare at the rubber model." Later, the China team made the world game truly invincible, further improved the "invention" hidden in the "shooting down", and suddenly made a move to pay for the "stamping" sound, resulting in different rubber tee sounds, and so on. This kind of T-shirt and foreign athletes know what to do. In order to crack this T-shirt, they racked their brains, saying that some foreign players' own teammates assigned us to wait on the athletes to observe in the back, indicating that they would become a pair of 1 singles and a pair of "doubles". The change of the long rubber racket should be blown up at this stage, however, the long rubber racket goes further. Deng Yaping's long rubber racket is used to cut, wipe and stick slow-paced balls. It is the first to play a sponge with a thickness of 1mm, and to play a long rubber fast-break bomb to create new skills. She didn't simply rely on the rotation of plastic in playing, but more played the "rhythm" characteristics of the long rubber racket. The flying path of the dragon's attack ball is short "floating", and the 1mm thick sponge racket is really a bit "thief", so it is not easy to use the attack power and anti-sticking forward of the fastball. Deng Yaping often has good continuous footwork and sharp forehand smash. The long rubber attack ball forces the opponent to slow down the hitting rhythm, so she takes the opportunity to smash the opponent's weight sideways and is out of breath. Changed the characteristics of the long rubber racket, she thickened the small sponge, changed the way of hitting the ball, and even played domineering;
The anti-glue racket was first invented in Japan. Later, they invented the loop ball with the anti-glue racket and used offensive friction to hit the ball, which made outstanding contributions to modern table tennis. China's first rubber-proof world singles champion, Ian Court, actually hid a fast rubber-breaking hand. The first hand movement, poor rotation when turning around and not serving, powerful bomb, pushing block and rubber-cycling ball were his third stunt. The apron ball can only deal with reverse rotation, forming a communication force in this respect. There is no switch, which makes him better at the sponge-proof racket. The more you spin, the more powerful the ball is, but it continues to pull red. Coupled with his powerful push, friction attack and impact attack, in order to achieve a perfect combination, he has not been able to win a big game. He finally got his wish at the 32nd World Table Tennis Championships and won the men's singles championship.
The development of anti-adhesive racket in the past 70 years shows great potential in advocating the traditional environment in China. The habit of promoting the use of anti-sticking racket to hit the ball and learning to change the circulation technique in an all-round way has been controversial, which has led us to miss this opportunity to take the lead in reform and innovation. Until the World Table Tennis Championships in Montreal, the Swissling Cup finally ended with 1989. The Swedish "Three Musketeers-1" Arup Waldner, persson and Elon of Apex beat them by their persuasive cycling fast break ability. With the years of the China team, Jiang Jialiang, Chen Longcan and Ito, the three best fast-break players in the world, who are active in sponge shooting, finally lost one. 0:5 table, the fact finally makes China table tennis circle, which has been wandering in inheriting the tradition of "innovation" and "change", understand that "development is the last word", and the technical upgrade of anti-sponge racket has changed the trend of table tennis in the world. Cyclic attack technology not only affects the development and integration of simple "hanging" and "forward" friction "cyclic attack technology, but also becomes rich skills such as drawing, pulling, red, hanging tears, drawing, writing, sealing, twisting, picking, hitting, smashing, grabbing and buckling. Liberated a group of outstanding China table tennis players' overall advantages of great creativity. In a short period of six months, China's table tennis has another spring recycling. Since the 43rd World Championship was held in Tianjin in 1995, China table tennis team has quickly broken through the modern concept and become the world champions in the square-Kong, Liu, He Wang, Zhang Yining, Wang Nan and other dazzling stars.
With the development of recycling technology, we have also experienced many changes in our concepts. With the racket on the first floor, I quickly stood on the glue and quickly attacked. More people only emphasized that the way of things was "influenced by the main assault backspin". The combination of hitting and rubbing will affect the speed. Some hard people think that the extra-thick floor is better, because they pursue the rhythm and speed of fast break near Taiwan Province Province, but they are considered to have lost their "speed" and been beaten? . During training, we often see a new baffle coach behind athletes-blocking their retreat, cultivating awareness, hitting the front desk and refusing support. On the premise of improving the rhythm and speed, the rising point and the highest point of the ball are trying to get close to the stage and hit the hit rate on the stage. During this period, arcing is very important, so the efficiency of using more ball speed is the main driving force. In addition, hitting the ball before the low arc is more deadly, the hard floor has a shorter heat preservation time, and the converted hitting power is low. -A ball with low friction will produce an arc. These functions are only to meet the requirements of the recent fast break. Moreover, the fast break is close to the power of the striker in the table, and it is often necessary to use "power" (commonly known as gentle power). This is because the ball bounces and hits the ball hard, which form a joint force to quickly hit the ball back in the near stage or stage. This is a very high skill. With the help of hitting the ball hard, the fast break often gives the opponent a full return. At such a distance, it is too late, but they often resort to rebound and fall into a passive position. Therefore, this kind of blow needs the efficient impact of backboard, and the harder backboard is just to meet this requirement. Some athletes can use the hard floor to return the ball at a faster speed in a short distance, while another nearby hitting arc requires a faster swing speed, so the ball has a smaller range of motion and must pass through? A method that often forces the ball close. In order to improve the hitting power of middle distance, athletes need to choose heavier weight backboards. Heavy wood is a natural component of the hard bottom plate, and the thickened plate itself can improve the weight of the racket and the center of gravity of the forward stroke. Many athletes have added a layer of 2mm thick and 6,7 mm thick paulownia wood at the back to improve the "potential" of the lens and increase the power of hitting the ball. Even now it has entered the era of arc fast attack, but judging from the traces left by that era, the requirements for the bottom plate are still the times. Our shop, a golfer in his fifties, introduced his backhand and double-sided loop. According to the routine, he recommended a suitable ball on both sides of the arc-Chaojie -B: 5.7mm in thickness and 90g in weight, but a few days later, he got its back: the speed of a rebound. There's nothing wrong with checking the backboard. I have never heard of such a reaction. I think maybe it is just transitional or untrue, because service is zero-risk communication and can't be defiled. She gave him a B-ultrasound, and he tried to think that we could take it away. But two days later, he came back and said that the board was a little hard and the feeling of pulling the ball was a little lacking. Can you change the range between the back panel and the front panel? This time, I asked him about several curling balls, and found that his curling balls all hit the ball near the table by pulling force and driving force. It was not what we thought, but his hair was pulled away from the standing force and rushed in. So I suggest Zhang Chaojie -A: thickness 6.2 mm, weight 95 g ... This result is very satisfactory, and he embarked on a journey. It gives an inspiration: fans of different ages and backgrounds have different playing times, friends, physical fitness and hitting habits. Everyone says that they have mastered some cycles, but the choice of the thickness of the ball plate should be different. With this experience, one day, a young player who claimed to combine fast break and loop ball played in storage and chose a super A bar, so we suggested that he choose a lighter, thinner and slightly softer super B bar. He is very satisfied that he has passed the exam. about
In the age of the ball, the bottom plate of the ring was thinner (except for single wood) and lighter. Because of the change of hitting mode, the combination of friction and impact, and the sudden difference of forward stroke cycle explained by the head coach of the national team: friction forces the forward stroke to bounce suddenly, so it is not surprising that it softens. We can see the modern cycle of development and progress. Elastic deformation and recovery, shooting elasticity is shown as thick and hard spherical sponge ball, deformation and recovery. The elastic efficiency he showed should mainly be the conversion efficiency of the rebound force of the ball, and the conversion efficiency of the ball to speed or speed through the backboard without impact force. Pull-ring backboard needs to be played for a long time immediately-which affects the deep deformation, and the deformation and recovery speed are faster-at least greater than the influence of the friction force of the ball rebound speed and the resultant force of the financial long moment, so the thinner and softer ball board is more suitable for pulling the loop ball. In addition, the above cycle is basically a completely independent development effort, and shooting needs to try to solve the problem of insufficient rebound caused by short ball or friction. For example, the ball board with high rebound efficiency of the pull ring overcomes the problem that the time ball board is easy to be hit more effectively than the force. The thinner and softer ball board is undoubtedly used to measure the ball, but it also has better power conversion efficiency in a dynamic swing force, which makes you feel that your hard ball is directly proportional to the static speed of the ball. But the ball board is excellent and hard to kill, but you will feel that the Force is inefficient. In the early 1990s, most athletes were still playing hard court and traditional thick bottom, a China-DPRK championship. In fact, Chen Zhijian is the backhand of Jin Chengxi, a continuous red lead medicine, far exceeding the half-lob. Chen Zhibin is a continuous North Korean athlete, but he is one of the best players in the national team. This ball looks very cold. Xu Yinsheng, President of Table Tennis Association: Why do our players rush in front of many round rackets? However, when a foreign player shoots, the board just leans forward slightly and can easily pull the button. We have also tried to improve the training, but fortunately, the NRK 12 board feels that the falling ball is constantly pulled forward, ensuring the arc of pursuing speed to increase the upward strength, and sacrificing the flying speed to increase the moment when the sponge rubber ball penetrates into the ball. You can't have your cake and eat it, let alone a simple method. Long-distance stretching in sponge rubber cannot produce the required energy and higher speed. Later, after using a softer and thinner ball board, the above problems were solved.
Because of the independent power of the loop ball, the hitting time can choose more motion range than the running range, and the fast exchange in the fast break can be increased in the near stage. The big action of hitting the ball will naturally choose a lighter ball board, which not only saves energy, but also increases the swing speed. Since the 1990s, no one in Europe would like a cricket bat with an extra 90g. Now, the younger generation of China fans and friends have begun to like this lightweight cricket bat.
On the contrary, with the development of the times, the sponge configuration has been replaced by a big backboard. In the past, fast-break players were all close to Taiwan, such as the soft sponge DHS sponge, which is most suitable for fast-break near Taiwan on rubber rackets, and the world-famous Japanese TSP raw rubber sponge 12. At H40 degrees, its hardness (indicated by the Shore hardness system of the Department of Homeland Security) will be lower. Sponges as soft as near-table fast break lie in the way they choose and try to hit the ball-the main influence. They need to give full play to the exact role of the strong impact of the bottom plate at the moment of hitting the ball. The hitting force of the ball board controls the fast, curved and released ball through the ball speed. But a sponge that is too thick and powerful will directly affect the feel of the ball and make them feel the number of people with the ball. This is the so-called state's most advanced power mechanism-the shooting power of bullets. In any case, Zhuang Zedong couldn't change the reason for using a hard sponge. Later, he volleyed Deng Yaping's famous sponge until it was only 1.5mm thick. We all experienced it. Once, a middle-aged golfer came to our store from Zhuozhou to buy a racket. He chose three pens with lighter weight (85g) and carbon overspeed -B, because his self-introduction was based on a fast break cycle. But two days later, he came back and said "bang, bang" when playing golf, so you don't have to listen, so you can't find the feeling of hitting the ball. At first we thought the backboard was too soft. She gave him a hard board, but it still didn't work properly. He tried to play, and I found that his attacking ball was a traditional pen-because he still kept a quick impact, he had no time to try again in an emergency, so I suggested that he only changed a sponge with a 40-degree 2. 1 mm, and his doubts disappeared, and our staff didn't know until evening. At this point, everyone's heart also fell to the ground with a stone.
The arc-drawing sponge has always been hard and thick, and the thick sponge has a large deformation depth when pulling the ball, which is easy for the ball. It is said that the hard and thick sponge has deformation and energy storage, and it is bound to have higher toughness for shooting and chief financial requirements, while the rotation speed rotates. Only change, because playing the big ball to adapt to the increased venue has brought about the softening and slowing of the ball path. Athletes adjust their own sponges, appropriately increase the thickness of sponges (2.2 mm) and reduce the hardness of sponges (below 46 degrees). Of course, the thickening thickness of anti-adhesion sponge should be considered. According to ITTF rules, the total thickness of sponge rubber should not exceed 4 mm.
The short racket is the material, and the material is the foundation. A correctly configured racket, of course, allows people to give full play to their own style at their convenience. However, people should learn advanced technical skills and tactical changes, so that the racket spirit in their hands can study hard and master a variety of skills to become a real "weapon", which is the essence expressed by the dialectical spirit in the reaction.
