The big secret of table tennis court

When I first started playing table tennis, people often asked how to choose the bottom plate of the table tennis bat. What is the most practical table tennis floor? The choice of table tennis floor varies from person to person, and what suits others may not be suitable for you. The following is the big secret of table tennis floor I compiled for your reference, hoping to help friends in need.

China is a big table tennis country, with nearly 100 domestic and foreign brands and nearly 1,000 varieties. There are many well-known brands with stable quality and good performance. As early as 1950s, the "Shunfeng" brand table tennis bat produced in Shanghai was the goal pursued by many athletes. It is said that this kind of racket is made of plywood accidentally left by fruit packaging boxes imported from Southeast Asia, so it is a racket with six layers of wood plywood. Because they don't know how to deal with the wood of the "downwind" floor, many manufacturers and research institutions have never been able to clone the ball board with the same performance, so there are "old downwind" and "new downwind" in the market. Old SF is out of print, leaving many stories. Zhuang Zedong, the former world champion of China and the triple champion of men's singles in the 26th-28th World Table Tennis Championships, is said to be worried about not having a suitable racket on the eve of entering the competition as a teenager. At that time, Liang Zhuohui, the founding father of the first national table tennis team, gave him his old SF board. Since then, he has left. " Yun Enting, the champion of men's singles in the 32nd World Table Tennis Championships, once bought an "old SF" in Huangmiao second-hand market in the old city of Shanghai. He always took it with him, but in the end he was "borrowed" by disciple Jiang Jialiang and didn't return it, which helped the latter realize his dream of becoming a world singles champion. "One board and two crowns" became a much-told story. 1999 At the Adult Sports Expo, an exquisite showcase was arranged in front of the booth of "Double Happiness", a leading table tennis equipment company in China, but there was a very old racket in it-a long colloidal racket used by former world champion and magician Zhang, which is said to be the floor of "Old Shunfeng". This unique arrangement has become a landscape at the Expo. Other famous rackets in that era were Guangzhou's "Three Lines" and "Literary Federation". At that time, most manufacturers used glue to make and sell finished rackets, so they didn't pay enough attention to the bottom plate, and each batch of racket bottom plates might be different. When an athlete accidentally gets a good ball board, he always puts it down and gets the treasure. At that time, the factory produced the ball board and the market bought the ball board in the "natural" stage.

196 1 The 26th World Table Tennis Championships was held in Beijing, which was the first world competition held in New China. In order to prepare equipment for this competition and organize scientific and technological research nationwide, table tennis, table tennis and rackets are famous all over the world. At that time, China's own "anti-sticking sponge racket" appeared on the market for the first time. I remember that the retail price of the market at that time was about 10 to 20 yuan, which can be said to be the best among high-end goods (because the previous rackets were generally below 5 yuan). Since then, Shuangxi Factory in Shanghai has started the research and development of table tennis soleplates, and it is often seen that they are working hard-taking the newly developed soleplates and tools to the national table tennis team and provincial and municipal professional teams to invite athletes to try them out. If they find the shape, grip or center of gravity of the racket inappropriate, they will take out a file or saw on the spot to correct it. This is Shuangxi 032 and 0 16 soleplates which have made great contributions to table tennis in China. At that time, it was almost impossible to buy such skirting lines in the market, because only professional teams could order them. Fans will be overjoyed if they can get an old cricket board used by athletes through friends.

In the early 1970s, the famous "Ping-Pong Diplomacy" ushered in the spring when table tennis flourished in China. The Asian-African-Latin American Table Tennis Invitational Tournament and the Chinese-foreign Table Tennis Invitational Tournament were held in Beijing one after another. The slogan "Friendship first, competition second" is deeply rooted in people's hearts. Many friends from the third world will accept the invitation of friendship even if their table tennis level is low, and Wan Li will come to Beijing not far away. Tianjin's "Friendship" brand table tennis racket is also in full swing and sold all over the world.

In 1980s, China entered the era of reform and opening up. After 1990s, there began to be more table tennis equipment on the market, and consumers began to have more choices. As far as table tennis floor is concerned, Japanese famous foreign brands such as Butterfly, TSP, Jasaka and Nitagu, Swedish Stedica, Banda and abala, and German Daunic, Tiba and Sunshine have since flooded into China. They all want to occupy a place in China, the largest table tennis market in the world, otherwise their real dream of "brand" will not be realized. At this time, due to the influence of the planned economic system, domestic enterprises are slow to act, with single products and rough workmanship, which can't keep up with the development and demand of the market. In fact, as early as the mid-1980s, the fast loop technique has gradually become the mainstream of table tennis in the world, but the floor in China is still the same. I remember a coach from China went abroad to teach football, and gave his domestic "famous brand" skirting board to local young athletes, but he was embarrassed and refused. After careful inquiry, I realized that the other party thought that these China skirting boards were too heavy and hard to play hoop ball. Our coach also thinks that the racket must be very forward when the ball is pulled continuously with the domestic soleplate. However, the racket modeling that leans forward too much will directly affect the combination with fast break and smash, which makes the combination of racket modeling and fast break very difficult. In the early 1990s, a famous Swedish enterprise wanted to enter the China market, and took the initiative to design five-story and seven-story floor boards for China athletes. Because I am not sure of my success and dare not rashly use my own brand, I got a new name "Abala" and marked it for the Chinese national table tennis team. Of course, if they use this brand well, they will become famous overnight, but if they don't use it well, it won't affect them. I didn't expect it to be an instant hit because it combined the characteristics of China athletes and joined the European understanding of the technical requirements of loop ball. Because domestic flooring can't produce corresponding products for a long time, it gradually withdrew from the leading position of national table tennis team and excellent sports teams in provinces and cities.

It was not until the mid-1990s that the emerging enterprises headed by "Yunenting" brand began to make great strides. As one of the founders of this brand, I realized the important role of the bottom plate in technology from my coaching career. In the late 1970s, the author accidentally got an imported packaging board and made two horizontal boards on a whim. Because he was not satisfied with the uniformity of the style of the racket handle in China at that time, he specially made the racket handle into a "waist-closed" shape with reference to the picture. Later, these two substrates were given to the then table tennis player Ito. It was these two skirting boards that were broken and then repaired. After being repaired and reused, he has been accompanying him into the national team and won the national championship, the Asian Cup champion, the World Cup champion and the world champion. In order to prevent it from being lost, his coach always keeps another floor specially for him. When the bottom plate in his hand is worn out, the coach will give him another one and take the broken one to repair. Also because of the preciousness of this board, I became interested in studying it. "Yunenting" brand soleplate is the first series of products in China divided by performance and price, but before that, the development and production of soleplate were mostly to meet the needs of athletes, and no product could meet the market demand. "Yunenting" brand soleplate not only introduced products suitable for different technical types, such as attack, all-around and defense, but also developed handles with different styles, such as waist-closing, long oblique, gourd, long straight, short oblique and short straight, and also divided them into several different price points according to market tolerance, and began to beautify the soleplate with different dyed handles. Because it is the first product that conforms to the laws of market economy, it still has many shortcomings, but it is fast. The rise of the brand "Yunenting" has inspired many domestic manufacturers, and since then, the types of domestic cricket boards on the market have become increasingly rich.

For a long time, due to the limitation of materials and technology, the appearance of domestic floors is always not as beautiful as that of expensive imported products. In order to change this situation, the Palme d 'Or Company invested by Hong Kong in Qinhuangdao took advantage of its unique advantages and took the lead in introducing imported dyed wood to decorate their products. Domestic boards can be compared with imported products, and since then Pairio has become a well-known table tennis equipment brand in China.

Another good quality board on the market is Yinhe. Because its founder, Mr. Korea Hua, is a retired engineer of the former Friendship Racket Factory, he is proficient in industrial production technology, and they are also a township-run enterprise system. Not only the quality of the boards produced is stable, but also the cost is low and the price is advantageous. Moreover, it is flexible in responding to the market and has a good market among many fans.

But it should be said that in the mid-1990s, many imported brands flooded into the China market, occupying most of the market share of high-end ball boards, while most domestic brands at that time were still in the primary imitation stage in R&D and production. They not only imitate the five or seven layers of imported brands in wood, material and structure, but also try their best to imitate others' shapes and handle colors in appearance, and some even make the packaging very similar to their own, hoping to cater to the trend of chasing foreign goods in the market and thus maintain their position in the market. Once, in order to regain the lost "floor" market, a large manufacturer specially hired a graduate student from a forestry college to help them develop products. When they brought several newly developed soleplates to Beijing for trial operation, people saw almost the same structure and materials as imported soleplates. At that time, graduate students asserted that imported materials must be used, because the wood in China was not good, so the imitation trend was general.

This situation did not change significantly until the late 1990s. The arrival of the 40mm ball era has greatly stimulated and enriched the enthusiasm and imagination of domestic manufacturers to develop new products. At Changsha Sports Expo in 2000, many manufacturers launched a series of new products with big balls. The wooden floor structure has also developed from the traditional five-story and seven-story to nine-story, ten-story or even more. Among them, the RG series soleplate developed by Shiaode, a well-known domestic brand, which has always paid attention to performance and quality, is particularly eye-catching, because the RG series soleplate not only has a clear technical design for the characteristics of the big ball, but also is the first high-performance product in the world with three layers of different fiber materials, which has created an era of independent intellectual property rights of the ball plate structure. RG series ball boards are often in short supply after entering the market. They are widely praised by professional and amateur players and exported to Japan at the same price as international brands, which proves the truth that "national is international".

Natural wood used to make floors does have different physical properties. Can domestic materials really make a cricket board suitable for high-level professional athletes? In this regard, Dragon Sword made a bold attempt. After repeated testing and screening, we finally developed a high-performance professional floor made of national materials and named it Dragon Sword. When it was given to the professional athletes of the national table tennis team and some provincial and municipal sports teams for trial use, the feedback was: "Its performance can be comparable to that of imported brand-name floors". In this way, we have another way to use local materials to create "excellent weapons" for our athletes. Of course, we can also recommend "domestic products" to Chinese people and players from all over the world without technical obstacles.

Faced with many dazzling brands in the market, I watched the excellent "foreign guns and foreign guns" in the hands of China players, as well as many fans and imitation shows attracted by the charm of the world champion Superman. It is always a puzzling question to choose what kind of bottom plate to choose for yourself. A young golfer once confided to me the confusion of choosing the soleplate: he took an imported soleplate signed by a former world champion and bought imported sponges of two bomb brands at a high price, but he couldn't play hard, couldn't play fast, and spent a lot of money and made a lot of trouble. I don't know that professional athletes have not only experienced long-term hard training, but also have good special qualities, which are incomparable to ordinary people. Moreover, before each practice or competition, they should coat the sponge with multiple layers of quick-drying glue, and use the solvent contained in the glue to volatilize gas, so that the micropores of the sponge are filled with gas in a short time, thus greatly improving the elastic speed of the racket. Most fans and fans do not have the above conditions, so even if you choose the full configuration of the world champion, it can only be a "similar not" result. What's more, most imported soleplates have been developed for a long time according to the feedback from foreigners. Different nationalities, different styles of play and different habits have different emphasis on the requirements of sole plates. The author thinks that we should choose the floor that suits us according to our own characteristics in order to fully display our own style. And blind obedience can only be an enthusiast at most.

The party's reform and opening-up policy has brought great richness to the market. At present, products of more than a dozen foreign brands can be bought in the market. Japanese products, led by Butterfly and other brands, are characterized by more oriental materials such as Japanese specialty wood and Asian paulownia, thicker straight boards, and more emphasis on the selection of bottom plates. They are the first to introduce products with various special materials such as carbon and aryl, which represents the understanding of table tennis bottom plates in the process of Japan's manufacturing industry connecting with the world. European products, led by brands such as "Stedica", are characterized by more wood from northern Europe and Africa, thinner board, and prefer the technology and structure of the ball board, such as hollow handle and ultraviolet radiation to increase hardness. This is the conclusion drawn by Europeans on the table tennis field when the world collided. Of course, with the process of international economic integration, Eurasian products are also learning from each other and integrating with each other. Tung wood is also used in new products in Europe, and many European varieties are included in Japanese product series. I believe that in the near future, China's products will stand on their own feet in the world table tennis arena by virtue of their all-round understanding of the world table tennis.

Expand the connection: the influence of table tennis venue on playing table tennis

The heavier (1) is, the faster it can be produced.

The speed at which you play is determined by the following three factors.

1. The opponent's playing speed.

2. The quality of the hitting object (mainly the racket).

3. The speed of the racket.

Even if you swing fast, a table tennis bat made of cardboard can't produce faster speed. Because the racket with light specific gravity is not easy to produce acceleration.

(2) An overweight racket will slow down the swing speed.

So, the heavier the racket, the better? Of course not. You must estimate the strength of your muscles to choose the weight of the racket, otherwise you can't swing at the best speed. Because the racket swings too slowly, the ball can't produce speed.

If you are a person who can only show your skills by swinging slowly, you can choose a heavier racket. However, these people must have some conditions. Because of long-term continuous operations, they must have strong physical strength. In addition, patience is also necessary.

If you are a right-brain player and inspired by winning or losing in billiards, you should choose a lighter racket that can swing quickly. If you are a left-brained player and want to wait until your opponent is tired before turning things around, you can choose a heavier racket.

(3) the thickness will cause dullness

The thicker the racket, the faster it can be thrown, but the speed of the ball is difficult to control, so it is a common performance to play with a thick racket. If you can play the same quality ball patiently at any time, it is suitable to use a thicker racket. If you are a person who plays hard or makes the ball changeable, you'd better choose a thinner racket.

People with insufficient strength want to rely on the elasticity of the racket to produce speed, so they should choose a thick racket. A good man must rely on his own strength to produce speed. When they want to stop the ball, they can stop it by the thinness of the board, which is suitable for using thinner rackets. A table tennis player with feeling and inspiration had better use a thinner racket.

Looking at table tennis players of all ages, the players who work use thicker rackets, because these people don't like changes and tend to win by patience and physical strength. Tactics, techniques and rackets must be consistent.

If you belong to the feeling school, fast break school, change school, or you are a player with this personality, it is better to choose a thinner racket. A thicker racket is suitable for opponents to perform outside the stage, and a thinner racket is suitable for opponents to perform on the stage.

Table tennis hitting technique

1, hit the arc

The hitting arc refers to the flight path of table tennis after it is hit. It is formed because the ball is subjected to gravity and air resistance during flight. The first arc (also called release arc) and the second arc (also called bounce arc) form a hitting arc.

The first arc refers to the flight path of the ball after being hit by the racket until it falls on the opponent's table. The second arc refers to the flight path of the ball from the opponent's table until it touches other objects (such as racket, ground, etc.). A reasonable first arc can increase the threat of the ball.

2, hitting speed

In table tennis competition or practice, the flying speed of the ball is a prerequisite for gaining time and initiative. The speed of the ball is determined by the swing speed and hitting power.

The "speed" of table tennis refers to the time it takes for the ball from the other side to land on our table (the second arc of the ball) to bounce back and land on the other side's table (the first arc of the ball).

The shorter the time, the faster the ball speed. Therefore, to improve the hitting speed, that is, to shorten the time between the second arc of the ball and the first arc of the ball. However, it is not enough to simply study the ball speed, but also to study the athlete's reaction speed and footwork movement speed.

Step 3 hit the ball and spin it

Rotation is also a very important technical factor in table tennis.

In mechanics, to make an object rotate, there must be a moment, which is equal to the product of force and arm of force, that is, M=FL. As can be seen from the formula, the greater F and L, the greater M, and the harder the object rotates.

According to the formula F=KN, the friction force (f) is directly proportional to the friction coefficient (k) and the positive pressure (n) between objects. Therefore, the elasticity, sponge thickness, hardness, rubber properties, hitting power, action time and so on of the racket bottom plate directly affect the rotation degree of the ball.

In addition, the mass, diameter, moment of inertia and smoothness of the spherical surface of table tennis itself are also important factors affecting the rotation.

4. Strike force

The hitting power is also one of the important winning factors in table tennis. Those who are strong and heavy-headed, when they encounter the opportunity ball, can often solve it in one board.

The table tennis circle in China has always regarded the weight of the board head as one of the important symbols of the basic skills and technical level of attacking athletes. The strength of hitting the ball depends on the swing speed of the racket and the coordination ability of the whole body at the moment of hitting the ball.

5. Landing point

The landing point refers to the landing point where the ball hits the opponent's table. Accurate and changeable placement can expand the opponent's movement range, give him some preparation time, create more opportunities for attack, and increase the difficulty for the opponent to give way, such as attacking and chasing the ball.

The function of forearm in table tennis hitting.

(1) Because the forearm can bend and stretch, it has the characteristics of speed lever, so it can increase the hitting power.

(2) The forearms are rotated forward and backward to guide the wrists and fingers to adjust the angle of the racket shape (because the wrists can only bend, stretch and rotate), especially when the backhand is pushed to the backhand block, the forearms must be rotated backward to reach a sufficient forward angle. Many students have overlooked this point.

(3) Form an appropriate angle with the upper arm according to different incoming balls. When the incoming ball is low, the angle between the forearm and the upper arm is slightly larger to ensure that the swing has enough acceleration distance; When the incoming ball is high, the angle between the forearm and the upper arm is slightly smaller, but it is necessary to explosively contract the forearm and speed up the swing speed of the arm, so as to speed up the hitting speed, increase the hitting power and friction to the ball, and improve the accuracy and lethality of hitting the ball.

(4) The swing direction of forearm determines the rotating nature of hitting the ball. Forearm swings from bottom to top, hitting topspin, and vice versa; Forearm swing from left to right, right hand, and vice versa.

Functions of wrists and fingers

(1) Accelerating wrist rotation (abduction and adduction) under forearm guidance is the key to enhance rotation.

(2) Adjust the racket face direction and angle, make a reasonable arc, and determine the hitting line.

(3) Moderate wrist and finger tension is beneficial to fixing the racket shape and improving the accuracy of hitting.

(4) Returning to tennis mainly depends on the wrist and fingers.

Jianxin yizhi table tennis

Table tennis is made of plastic and is spherical. The standard ball should be 40mm in diameter and 2.5g in weight. The racket is made of a wooden bottom plate and a surface covering, and its size, shape and weight are not limited. There are two kinds: direct and transverse.

Players choose rackets with different performances according to different styles and techniques. The table tennis table is rectangular, with a length of 2.74m, a width of1.525m and a height of 0.76m from the ground. The countertop should be parallel to the horizontal plane. The standard net height is 15.25 cm, perpendicular to the table. The net divides the table into two equal table areas.

What are the benefits of playing table tennis?

1. Safe, because table tennis is a net, which is safer than physical contact sports such as football and basketball, and is suitable for middle-aged and elderly enthusiasts who like fitness.

2. Stay healthy. Table tennis can fully exercise the human body, so that the human respiratory system, digestive system and sports system can be fully exercised.

3. Puzzle, table tennis can not only develop people's physical qualities such as speed, agility, strength, endurance and coordination, but also exercise and cultivate people's good psychological qualities such as courage, tenacity, wit and decisiveness.

4. Collaboration, table tennis makes people's reactions faster, their thinking sharper and their movements more coordinated. Table tennis doubles can also strengthen the spirit of teamwork and cultivate a sense of tacit understanding between the two.

5. Comfortable, playing table tennis can also adjust people's mood and make people feel happy and cheerful; It can develop human brain intelligence, improve thinking ability and promote intellectual development.

How to play table tennis well

There are many different ways of playing table tennis and many tactics. No matter how much table tennis tactics change, its technique can not be separated from four basic factors, namely strength, speed, rotation and landing point.

1. strength, hitting strength is one of the winning factors of table tennis. Those with great strength can often solve the problem when they meet the opportunity ball. If you smash hard in the middle of the attack, so that the other side can't catch well, then you must play with your strength.

2. Speed, "quickness" is one of the main winning factors in table tennis, and it is also an important means to strive for initiative, create spike opportunities, make opponents unprepared and score directly. As a table tennis term, speed refers to the time of table tennis flight and the length of hitting interval.

In order to minimize the opponent's reaction time, preparation time and action completion time, we must seize the time and try to return the ball to the opponent's table in the shortest and fastest time, so that the opponent is caught off guard.

3. Spinning, in order to increase the difficulty of the opponent's counterattack, you can also make various spinning balls to force the opponent to make mistakes. Now the development of table tennis technology requires both rotation and fast ball speed.

4. Landing point, compared with the table of table tennis, the area of table tennis is relatively small. It is also important to make your ball more powerful. The landing point of table tennis refers to the landing point on the table.

Proper landing point and hitting line can force opponents to run back and forth, left and right, force opponents to change hitting methods, and increase the difficulty for opponents to return the ball.

Correctly judge the speed of the ball

Table tennis moves in an arc, so the speed of the ball can be measured by the time it takes to run an arc.

No matter what hitting method, strength, arc requirements and other factors are adopted, as long as the ball runs in the arc for a short time, it means that the ball is fast; A long time means that the ball is slow. The range of the arc is determined by two time periods.

The time to prepare for hitting the ball (that is, section A-B) starts at the moment when the opponent hits the ball in the first arc, starts at the moment when the ball hits the table in the second arc, and ends at the moment when the opponent swings the ball and touches it. As long as the arc running time is shortened, that is, the batting preparation time is shortened. If you hit the ball early, the return speed will be faster, and vice versa.

The running time of the ball in the air is from the moment when the racket hits the ball to the moment when the ball falls on the opponent's table, which is called the first arc. If the arc is low, the running speed is fast and the hitting distance is short, it also means that the ball speed is fast, and vice versa.
