Table tennis racket purchase basic knowledge particle surface
The rubber of the table tennis racket mainly consisted of normal rubber, raw rubber, and long rubber. Positive glue: the largest and most flat particle, which is characteristic of fast ball speed and slightly heavy. The use of positive glue required the user to have small movements, fast retracting of the forearm, and more hits when touching the ball. There was little friction or even no friction. There were fewer players who played the positive rubber style. President Liu Guoliang, France's Yuan Jianan, and India's Batra all played the positive rubber style. [Uncooked rubber: The granules are slightly slender. Its characteristic is that the control of the up-and-down spin needs to be played more to be better mastered. The route of the ball is erratic. This characteristic makes it difficult for opponents who are not familiar with the uncooked rubber to deal with it.] Ito Miho and Sun Mingyang used raw rubber. The raw rubber ball was fast, stable, and stable. The thinner the sponge, the weirder the ball would be. The thicker the sponge, the faster the ball would be. It was usually used in the backhand of the racket. The " bounce " was the most lethal weapon of raw rubber. It had the characteristics of fast speed and heavy return. Long rubber: The particles are the thinnest and most slender. It is usually used by the players who cut the ball. However, in the past two years, the use of raw rubber for cutting the ball has gradually increased. The long rubber particles were very long and basically did not take the opponent's rotation. After receiving the impact of the ball, the long particles acted as a buffer. If it was an offensive long rubber, the sponge should be thicker to ensure the speed of the bounce, while the long rubber sponge of the ball cutter was thin, and it was more sought after to be able to discharge the power of the ball. When choosing a grain-faced rubber, in addition to considering the characteristics of the rubber itself, it was also necessary to take into account the characteristics of one's own fighting style, basic skills, and the base plate. If you are a close-up fast-attack player, normal rubber may be more suitable; if you want the ball to be strange, fast, and have a certain sinking effect, you can consider raw rubber; if you are good at cutting the ball, you can consider long rubber. At the same time, he also had to pay attention to the rules of the International Table Tennis Federation on the rubber of the table tennis racket. For example, the surface of the racket used to hit the ball should be covered with a layer of ordinary particle glue with the particles facing outward, together with the glue, the thickness should not exceed 2 mm; or covered with sponge glue with the particles facing inward or outward, together with the glue, the thickness should not exceed 4 mm.

Basic Skills of Table Tennis Beginner
The basic skills of table tennis beginners included many aspects. The first was the practice of basic postures. Correct postures were the foundation for mastering basic movements. For example, standing posture, footsteps, and other aspects needed to be maintained correctly. If a beginner could get the guidance of a table tennis coach or the help of a friend with standard movements to correct his movements, his level would improve faster. In terms of hitting skills, the one-point attack of the forehand was the first training subject that many people came into contact with. Although the movement was simple, it was very important. The two-point attack of the forehand required the movement of the feet on the basis of the one-point attack of the forehand. The backhand fixed-point/two-point attack and the forehand attack training method were basically the same. In addition, he also needed to master basic hitting techniques such as sideways attacks and backhand shots. Serve was also an important part of basic skills. One had to practice using different ways to serve the ball at different speeds, with different rotations, and with different landing points. Receiving the ball was also crucial. It required accurate judgment, quick reaction, and reasonable control of strength to return the ball to the opponent's uncomfortable place. As for the pace, you should pay attention to avoid problems such as the center of gravity not leaning forward. Tilting forward (the left foot is in front of the right foot, the forefoot is exerted, and the body is tilted forward by about 45 degrees) helps to relax the balance when starting and standing. If the body is not tilted forward enough, it will cause problems such as slow movement and insufficient shooting distance. In addition, beginners need to master the correct grip, the wrong grip will affect the performance; they also need to master more skills such as rubbing the ball, picking, pulling the loop, etc.; practice with more friends can make the practice more close to the actual game; and pay attention to the control of the rhythm and power of the ball. If it was just amateur practice, the basics of attacking the ball with both hands, footwork, pulling the ball with both hands, and rubbing the ball needed to be mastered. It was also important to shape the movements. This was the cornerstone of stable performance. One could use people with solid basic skills to feed the ball, serve the ball, feed the ball (it was better to practice more balls), imagine the ball, and other methods to shape the movements. During the practice process, one technique should be the main focus, and at the same time, it should assist in the comprehensive practice of the techniques that one already knew. Finally, the various technical movements would be shaped. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

The ball had to bounce back and forth on the table. The players had to hit the ball after it bounced up and before it hit the ground, hitting the ball to the opponent's table. If one side cannot hit the ball, return it out of bounds, or drop it into the net, the opponent gets a point. 2. ** Basic Awareness Cultivation ** - He had to develop the awareness of moving to the right position before hitting the ball. According to the direction, speed, and landing point of the ball, he quickly moved to the right position to hit the ball. ** 2. Basic Skills Learning ** 1. ** Batting Skills (Basic Skills)** - [Forehand attack: This is one of the most basic hitting skills.] The horizontal racket user had to master the correct movements, including turning the waist, leading the racket, hitting the ball, and swinging the racket.

After hitting the ball, you must return in time. - ** Cross Step **: Mainly used for large movements in the side position, such as when hitting the ball from the backhand position to the forehand position. 3. ** Serve ** - One had to learn a variety of serving methods, such as serving sideways and serving with the backhand. The changes in the serve's rotation were also very important, such as backspin, topspin, side spin, and running ball. For example, a backspin ball could cause the ball to sink on the opponent's table, making it easier for the opponent to return the ball to the net; a topspin ball would make the ball feel like it was rushing forward, making it easier for the opponent to return the ball out of bounds. 4. ** Defend ** - Ask your teammates to carry out targeted practice, let your teammates use the same offensive means to attack continuously, and you continue to defend yourself. Experience the key feelings of defense, such as controlling the landing point of the ball, controlling the speed of the ball, etc., and try to make the ball return to the position on the opponent's table that is not easy to attack. ** 3. Training methods and mental adjustment ** 1. ** Training Method ** - ** Wall practice **: This is a good way to practice your hand feel. By hitting the ball against the wall, you can get familiar with the ball and improve your control of the ball. - ** Dual training **: Practice with your partner. You can practice both backhand and backhand attacks, pulling, serving, and receiving. - ** Single movement practice **: Practice each basic movement separately, such as serving, receiving, sideways attack, backhand shot, etc., to practice each movement skillfully. 2. ** Mentality adjustment ** - He had to maintain patience and perseverance, because the improvement of table tennis skills required a lot of repetitive practice.
