In terms of performance, the single-cypress blade has about 150 annual rings on it, which is most suitable for its elastic speed, ball-eating depth and depth. Jiang Penglong and Liu Chengmin are nothing more than that. To be honest, your Dak 600 is over 200 years old. If the performance really cannot keep up with its price. But I have nothing to say if you choose.
The characteristics of single juniper are deep ball penetration, strong spray feeling, and even speed rotation. This is suitable for dispatching fierce players. Just look at Jiang Penglong, Ryu Seungmin, Jin Taeksoo and other famous single cypress players to illustrate this point. Therefore, if you want to make a forehand loop, you can choose the domestically produced Kuang San. It is best if the hardness does not exceed 40. Because the particles of domestic rubber are arranged vertically, it is suitable for arc play. For backhand fast breaks, you can choose Tianji 3, which provides you with exquisite control while being crazy.
However, in the end, I still recommend that you don’t buy this piece easily. After all, the most expensive is not necessarily the best. Moreover, this racket is indeed not made for playing ball, it has its own commemorative and collection value.
The table tennis racket consists of three parts: base plate, rubber and sponge. The reasonable combination of the three determines the quality of a racket. We often refer to table tennis rackets and sponges in terms such as: "speed", "control" and "elasticity", "soft and hard base", etc. In fact, these indicators do not have unified values ??in the industry, but are divided by major manufacturers in order to provide reference for consumers when purchasing.
The performance index of the blade, the so-called "speed", refers to the efficiency of the batting force acting on the ball through the racket, converting it into the flying speed of the ball; the so-called "spin" refers to the efficiency of the batting force The force acts on the ball through the racket, converting it into the efficiency of the ball's rotation speed; the so-called "control" refers to the length of time it takes for the ball to leave the racket when hitting the ball with the same force and method (this is different from the "soft and hard balls" of the blade) "Related to "feel"); the so-called "effective hitting range" or "hitting sweet spot" refers to the position and range where the batting force can be concentrated and transmitted to the blade (this is related to the shape, structure, and material of the blade). The above four aspects of performance not only have different characteristics, but are also interconnected and influence each other. Therefore, when purchasing a baseboard, you should not only look at the appearance and number of layers, but also the wood grain arrangement; not only listen to the sound, but also feel its softness and hardness with your fingers when tapping; not only read the baseboard The relevant indexes indicated on the ball must be weighed with different forces in order to feel its force efficiency and comprehensive performance. In general, after the blade has gone through a period of mixed competition, the labeling of various indicators is now becoming more and more similar. Generally speaking, each blade manufacturer will indicate the two indicators of "speed" and "control". The indicators are divided into grades of 1-10 (or 1-12). From my personal shooting experience, the general indicator indicates 6. It is slightly worse, 7 is average, 8 is good, 8.5 is good, and above 8.5 is very good. But this is only limited to foreign brands such as Butterfly, STIGA, TIBHAR, etc. The domestic division is still somewhat confusing.
Performance indicators of rubber. Positive rubber is also called short-grain rubber. It is characterized by good elasticity, fast speed, stable hitting, and no spin. It is suitable for fast attacks close to the table, especially left-push and right-attack types. The method is one of the most commonly used types of rubber for straight-line fast-break players. In the past, a large number of world champions such as Zhuang Zedong, Li Furong, Jiang Jialiang, Xie Saike, etc. all used positive rubber sponge for pen-hold shooting. Today's world champion Liu Guoliang also uses this type of rubber. If you feel that your wrists are flexible but your arms and waist and abdomen are not strong enough, it is best to choose a rubber racket that wins with speed. There is also a medium-grained rubber on the international market that is between short-grained and long-grained. It has a unique effect of non-spin attack. This rubber is not afraid of the opponent's strong draw or backspin. , in the past, the ball was always non-spin and erratic, making it difficult for the opponent to exert his strength. It is called "magic rubber".
Reverse glue is characterized by strong batting rotation, stable hitting, and easy control. It is suitable for arc type or arc combined with fast break style. Because of its stable hitting and good ball control, it is also the preferred type for beginners. For professional players, there are a variety of anti-adhesive sponge rackets with different properties to choose from. For example, the rubber has strong stickiness and the matching sponge is soft and thick, so it has good "biting" and "wrapping" characteristics of the ball. Reverse sponge rubber is currently the most commonly used rubber for vertical and horizontal shooting players. Almost 100% of European players use this type of rubber, and nearly 80% of Asian players use it. Because this kind of rubber takes into account the requirements of speed and rotation better.
At present, most of the top international players use anti-adhesive rubber. For example, Waldner, Persson, Seve, Ma Wenge, Wang Nan, etc., who combine loop play with fast break play, Gai Ting, Wang Tao, Kong Linghui, Deng Yaping, Li Ju, etc., who combine fast break play with loop play, penholder grip Ma Lin, Yan Sen, Feng Zhe, etc., all of them are made of reverse rubber on the front or both sides. Players who play reverse rubber all hope that the rubber has high binding force, that is, the rubber surface must be sticky, so that it can have a high friction coefficient. Except for professional athletes who have the conditions to change the rubber when playing games, amateurs may not have this condition, so they must know how to protect the stickiness of the rubber. The simplest way is to use a soft foam sponge dipped in water to clean it after each practice. There are also special cleaning agents on the market, which will have better results. After cleaning, cover it with Mylar to protect it from dust and oxidation.
Raw rubber Raw rubber is rubber with upward particles and a diameter greater than its height. Its characteristics are that the ball sinks and the ball spins weakly. Because the raw rubber has the effect of reducing rotation, it is especially easy to control the ball. At present, a group of horizontal and double-attack players adopt a combination of forehand reverse rubber (looping) and backhand raw rubber (quick dial and short swing) in order to obtain changes in batting. Today's world champion Wang Tao and famous players Chen Jing and Geng Lijuan all use the backhand raw rubber playing method. South Korean and North Korean female players are particularly fond of this matching method. Rubber with this kind of performance can be used as an option for back-side rubber for pen-hand shooting and reverse shooting.
Long glue This is a thin and long rubber covering a thin sponge. The rubber sponge was invented in my country in the 1960s. At that time, Zhang Xielin used this kind of rubber to create unpredictable balls, and he was called a magician in the table tennis world. This is because this kind of rubber ball will produce abnormal rotation on the racket surface. Typical changes are: the backspin ball played by the opponent will fly back with top spin when the opponent uses long rubber to rub it; the topspin ball played by the opponent will fly back. , your side uses long rubber to block and then flies back with backspin; when you use a chip to hit the opponent's loop ball, the ball will spin more, but when you use a chip to return the ball, it will not spin. These abnormal changes often cause the opponent to make mistakes or return high balls. People who are not familiar with the performance of long rubber can often win easily when playing this kind of ball. However, when playing with this kind of rubber, not only will the opponent make many mistakes, but it is also difficult for one's own side to master the ball, which greatly reduces the viewing and entertainment of table tennis. In May 1998, the ITTF held a council meeting in Durban, South Africa, and made a decision by 19 votes to 18 to ban the use of long rubber, and stipulated that the ratio of the height to diameter of the long rubber should not be greater than 1:1. . Young athletes must not use long glue. On the one hand, long glue is difficult to master. On the other hand, if you are not careful, it can easily cause wrong shaping. The Chinese Table Tennis Association has already made it clear that long rubber is not allowed to be used in youth competitions.
Anti-arc rubber is also used to deal with looping balls. There is also a reverse-adhesive sponge rubber called "anti-arc rubber". This kind of rubber has no stickiness on the racket surface, and the surface is smooth and slightly astringent, making it easier to hit the ball. The running speed is slow, the arc is short, and the ball sinks and erratic after landing, making it difficult for opponents to make conventional judgments. It is especially effective against loop balls. As mentioned above, Cai Zhenhua used this kind of rubber on the back. Among the various table tennis racket surface coverings mentioned above, in addition to paying attention to the selection of rubber characteristics, you should also pay attention to the selection of sponge, that is, pay attention to the thickness or thinness, hardness or softness of the sponge. Generally speaking, thick sponges eat the ball deeper, bite the ball for a longer time, hit the ball with more stamina, and have more obvious characteristics when pulling the ball; on the contrary, thin sponges eat the ball for a short time, hit the ball quickly, and control the ball well, but The ball does not have enough stamina to kill the opponent easily. As for the hard sponge, it has the characteristics of short bite time and fast ball speed, which is suitable for fast break play; while the soft sponge has slower ball speed, but has better control of the ball. Most people can hit it more smoothly and more steadily.
About choosing a wooden racket
Before choosing a wooden racket, you must first determine your grip. Horizontal shooting is generally suitable for players who are tall, have a large range of movement, and are more powerful; while pen-hold shooting is more suitable for players with quick reactions, many changes, and flexible bodies. From the material point of view, the racket surface materials currently on the market include: composite board, all-wood board, cork plus carbon fiber, all wood plus carbon fiber, all wood plus titanium fiber, etc. The wooden board of the racket surface is divided into several layers. Mr. Song, a salesperson at a table tennis equipment store, told reporters: "The layers of racket boards now generally range from three to more than ten layers. There are also single-board ones, but the number is small. The price is also relatively expensive, and most people commonly use five-layer rackets. "As for the handle, there are weights. "The one with a heavy head and a light handle is suitable for offensive players, and the one with a light head and heavy handle is suitable for defensive players, and the center of gravity is in the middle. is suitable for a comprehensive play style.
Nowadays, there are not only hollow handles on the market, but also handles with adjustable center of gravity. It is a good choice for beginners, especially those who do not have a fixed playing style. ”
About choosing rubber
Except for cheaper rackets that are finished rackets, it is generally necessary to select additional rubber for the racket. Rubber can be divided into positive rubber, reverse rubber, and long rubber. Its selection and playing style are inseparable. "The positive rubber particles are facing outward, and the ratio of particle height to diameter does not exceed 1:1. It hits the ball stably and quickly, and can also cause a certain amount of spin, and is not easy to spin. , suitable for close-to-the-table fast-break style of play. The anti-adhesive particles face inward and the smooth side faces outward. It has greater viscosity and friction, which can easily cause strong rotation. It is suitable for players who play loops and slices. It is also the most commonly used rubber at present. Long rubber also has particles facing outward, but its particles are long and soft, and the rotation changes strangely. Generally, the incoming ball determines the rotation intensity of the return ball, and produces opposite rotation, making it difficult for the opponent to adapt. The user must have comprehensive skills and The style of play is varied. "Beginners should still choose conventional rubber such as reverse rubber or positive rubber," Mr. Song said.
About choosing a sponge
The last thing to talk about is the sponge. The main things to consider for the sponge are its hardness and thickness. "The thickness of the sponge is generally between 0.5 mm and 2.4 mm, and the hardness is between 30 degrees and 50 degrees. Generally, the harder and thicker the sponge, the greater the elasticity and the faster the hitting speed. However, this does not mean that the harder the sponge, the thicker it will be. The better, because not only will the racket be too heavy, but it will also be too elastic and difficult to control. Beginners are advised to choose a reverse rubber sponge with a thickness of 1.8 to 2.0 mm and a hardness of about 40 degrees or a positive rubber sponge with a hardness of about 35 degrees. However, most of the ones currently sold on the market are sponges and rubbers that have been glued together, and the models are easy to match, and generally sales staff will provide free sticking services when they are sold. ”
