Table tennis racket rubber standards

Table tennis is an interesting sport that can arouse people's emotions. Sometimes when you encounter something annoying, you will sweat profusely after playing table tennis for a while. That unique comfort can refresh your spirit. Below I will introduce the rubber standards for table tennis rackets to everyone. Welcome to read.

Table Tennis Racket Rubber Standard 1

The ITTF stipulates that the rubber on the table tennis racket shall not exceed 2 mm, and the sponge and rubber shall not exceed 4 mm.

The base plate is generally It is about 6.5mm, the reverse glue is 1.8mm-2.0mm, the positive glue is 0.8mm-1.0mm, and the long glue is more than 1.5mm.

Choose a suitable blade according to the type of playing style:

(1) Close to the table fast break type

This is the Chinese table tennis team in the world table tennis world It has been a traditional style of play that has remained popular for decades. Athletes who use this style of play usually use positive rubber sponge rackets or reverse rubber sponge rackets. World champions Liu Guoliang and Deng Yaping are the leaders in this style of play. The fast attack near the table first requires a fast batting rhythm and strives to attack the rising and highest points of the incoming ball on the table. The range of batting movements is small, and force methods such as explosive power and extra force are used. In order to improve the explosive power and suddenness of small-movement shots, athletes usually choose heavier rackets first. The weight of the pen-hold racket blade covered with sponge rubber on one side should be about 95 grams. The weight of the racket blade covered with sponge rubber on both sides should be lighter. Generally, exist. Below 90 grams.

In order to increase the speed of the ball, fast break players near the table require the hitting arc to be as low and flat as possible. Therefore, they often use techniques that require less friction and more hits to make the ball come off the board faster, such as: Hurry Up , quick pull, fast break, bounce and smash and other offensive techniques. This requires the sponge to be softer and thinner, and the batting feel of the blade to be relatively firm. Therefore, athletes usually choose a seven-layer blade or a thick blade with a thickness of more than 6.5 mm.

In order to ensure the speed of attacking the ball close to the table, fast-break players usually choose positive glue with outward-facing particles or reverse glue with medium surface viscosity, shorter particles, and faster speed. Positive rubber is a kind of rubber with hard glue, outward-facing and larger particles. It can hit the ball faster and produce a certain amount of rotation. It should usually be matched with a rubber with a thickness of 1.8-2.1 mm and a hardness of about 35 degrees. Sponge; reverse glue should be matched with a sponge with a thickness of 1.5-2.0 mm and a hardness of about 40 degrees.

(2) Loop fast break type

This is a loop ball scoring style that combines rotation and speed, and is the current mainstream style of play. World champions Kong Linghui, Wang Nan, Li Ju, etc. all belong to this style of play. Athletes use reverse rubber pads. The loop fast-break style requires the unity of rotation and speed, so "whip-type" attack techniques that combine friction and smashing are often used, such as: picking, pulling, reverse tearing, reverse belt, wiping, skimming and other techniques. In order to ensure sufficient friction and bounce speed when hitting the ball, the ball lever selected should not only have enough depth to eat the ball, but also have sufficient base strength. Therefore, athletes often choose a five-layer baseboard with soft wood and good elasticity. The loop fast break technique uses more changes in speed and rhythm than the wide game. Sometimes it is close to the table, sometimes it is away from the table, sometimes it is the rising period and high point period of the hit ball, and sometimes it is the falling period of the hit ball, so it not only has a large range of movement , and the range of the hitting action is larger and the force is exerted more independently, which requires the weight of the racket to be lighter to ensure free swing and better feel when hitting the ball quickly. Therefore, the weight of a straight board is generally about 85 grams, especially a straight board covered with sponge glue on both sides should be lighter; the horizontal board should also be less than 90 grams. In order to ensure the rotation of the loop attack, you should choose a reverse glue with better surface viscosity and slightly longer particles; in order to ensure the speed of the smash attack, you should choose a harder (above 45 degrees) and thicker (2.1-2.2 mm) sponge.

(3) Fast break combined with loop offensive play

This style of play combines fast break technology and loop technology, and has the characteristics of both styles of play. Usually use a reverse rubber sponge racket or a reverse rubber side and a raw rubber sponge racket, such as world champions Wang Tao, Wang Chen, and national players such as Yan Sen and Ma Lin. The fast break combined with loop offensive style of play requires the selection of a paddle that is both suitable for fast breaks and can draw loop balls, and is used to combine fast breaks with loop balls. People who use more looping skills should choose a five-layer blade with a softer feel and thinner thickness. On the contrary, people who use more fast-break skills should choose a harder and thicker seven-layer blade. The thickness of the base plate is generally about 6.5 mm. The weight of a straight base plate with sponge glue on one side is about 90 grams, and the base plate with sponge glue on both sides should be less than 85 grams. The weight of a horizontal plate is usually between 90-95 grams. For reverse glue, you can choose a sponge with a thickness of 2.1 mm and a hardness of about 45 degrees. Since most backhand attacks on the horizontal board are near the table, the sponge used for backhand shots should be thinner than that for forehand, which is more conducive to fast attack techniques. application.

There are also some people who choose to use raw rubber sponges for fast attacks. Raw rubber is a kind of positive rubber with soft gel, greater elasticity and larger particles. It can attack the ball quickly but has poor rotation. , so the attack arc is relatively flat (sinking), so the corresponding sponge degree should be 1.8-2.0 mm and the hardness should be around 35 degrees; some people also use long rubber or semi-long rubber to attack.

The long rubber particles will be overwhelmed by the incoming ball at the moment of hitting the ball and immediately bounce back in different directions. Therefore, it is not easy to rub the incoming ball and cause autonomous rotation, so the hitting ball often has the counter-rotation of the incoming ball. At the same time, because the particles falling in different directions are not equal, the direction of the rebound force is also different, so the arc of the return ball is erratic. The thickness of the sponge usually selected for long rubber offense is 1.0-1.5 mm, and the thickness is high. This can not only maintain a certain batting speed, but also make the return arc erratic and sinking.

(4) Combination of attack and cutting

Although this style of play is called a combination of attack and cutting, it is by no means 50% attack and 50% cutting. People use the serve to attack and cut back as the main means of scoring. The change of cutting the ball is just to disturb the opponent and create opportunities. This is the case for world champion Ding Song. At first, many people thought that he was a defensive player and treated him as a defender. There are also some people who use chipping changes as the main scoring method, and offense is just a way to disturb the opponent, such as the national player Wang Hui. Athletes who combine attacking and cutting methods must have a comprehensive technical mastery. In order to ensure the rotation of cutting and loop attacks, they usually choose anti-glue with better surface viscosity and slightly longer particles; in order to ensure their cutting and defensive performance. With good control, always choose a sponge with moderate thickness (1.5-2.0 mm) and moderate softness and hardness (about 40 degrees). The core of the combination of attack and slice is "change" - rotation change, attack change, landing point change and rhythm change, etc. Therefore, the racket selected must also fully reflect and adapt to this change. Many people choose rackets with different performances on both sides. For example, one side has reverse rubber for active rotation and attack, and the other side uses an extremely thin sponge with a thickness of less than 0.8 mm with long rubber, regular rubber, or raw rubber; some people also use it. Anti-arc rubber, which is a kind of reverse rubber with low elasticity and non-stick surface, is used with a very soft low-elastic sponge with a thickness of about 1.5 mm for chip control and change. The blades used in combined attack and chipping styles are usually larger in size, so the batsman is softer and can control the ball for a longer time. The narrower surface of the board moves the center of gravity forward when hitting the ball, which is also helpful for hitting the ball hard off the table. Table Tennis Racket Rubber Standard 2

(1) The size, shape and weight of the racket are not limited, but the bottom plate should be flat and hard;

(2) The thickness of the bottom plate should be at least 85% Natural wood, the adhesive layer of the reinforced base plate can be made of fiber materials such as carbon fiber, glass fiber or compressed paper.

Pay attention to the strength of the serve

When it comes to the strength of the serving technique, especially the strengthening of the serving technique, people often Think of the consequences of adding force: Either the ball flies out of bounds, or the ball bounces too high. But in fact, when you serve a short ball with added force, the ball is short, turning, low, and has a good landing point; when you serve a long ball with added force, the ball is long, fast, turned, and lands in the left and right corners. The artistry and technology of table tennis. Not only can it be done in practice, it is also correct in theory. As long as we control the ratio of impact force and friction force when adding force, appropriately increase the length of the ball when it rubs on the racket, reduce the friction thickness, and appropriately extend the time when the ball rubs on the racket, we can achieve the above effect.

Spin Skills

The variety of table tennis spins and the richness of the resulting curves are unique among all ball sports. So how to create a variety of rotations, especially rotations with similar actions but different properties? The following should be mainly noted:

⑴ Use different parts of the racket to hit the ball and rub the ball to produce balls with different spins. If you use the underside of the racket surface and the upper side of the racket surface to hit the ball and rub the ball, you can produce a rotating or non-rotating ball at the corresponding time;

　⑵Use a spiral to lead the racket. Hitting and rubbing the ball will produce different spins.

Touching the ball in the downward spiral direction will produce a downward spiral; touching the ball in the upper spiral direction will produce an upward spiral;

⑶ Different ways of exerting force with the wrist will produce different rotations: if it is a bullet firing force, then It does not rotate very much. If it is an upward spiral linear friction force, it is an upward spiral rotation;

⑷ Increase the thickness of the sponge appropriately to enhance the stickiness of the racket, which can enhance the rotation of the table tennis ball. Especially after using a big ball, this issue becomes more important;

⑸ Increase the time and distance when the resultant force acts on the racket: For example, when serving an extra side spin ball: apply a ball close to the right side of the racket surface rub the ball; if you are serving a side spin ball that does not spin: use the part close to the left side of the racket surface to rub the ball;

⑹ Increase the movement appropriately, speed up the swing speed, and cut it thin: in this way, when swinging Under the condition that the speed direction is far away from the center of the ball, the faster the swing speed is, the greater the hitting force will be, and the force of the racket rubbing against the ball will also increase, so the rotation of the ball will be strengthened; when hitting the ball and rubbing the ball on the upper side of the racket, You can send the ball with or without turning at the corresponding time;

Changes in skills

The service technology is unpredictable and often makes the opponent at a loss. But we often see that in competitions, including some major competitions, some athletes only use one or two serving techniques from beginning to end. The serving technique is monotonous and the landing point is also monotonous, which often makes the opponent adapt quickly and puts him in a passive position of being beaten. Therefore, prepare more sets of serving techniques, such as forehand, backhand, sideways serving technique, upper side spin, lower side spin, long side spin, short side spin, etc., give full play to the initiative in the serving technical stage, and strive to achieve: six combinations + combination, and preparing several sets of service techniques and attack routes when serving, often put us in an invincible position!

Technical innovation:

Continuously improving the quality of serving technology and constantly creating new serving technology are the needs of the development of table tennis and are also a manifestation of the vitality of table tennis. In the face of a new high-quality serving technology, because the opponent is unfamiliar with it, the conditioned reflex has not yet been established in the mind. Therefore, when hitting the ball, you feel uncoordinated, uncomfortable, or even helpless, which leads to direct or indirect scoring with the serving technology, which fully demonstrates the great power of the new serving technology.
