1, different anti-glues of "direct friction" or "hitting first and then wiping" when hitting the ball.

Although new products emerge one after another, according to the different surfaces of reversal films, they can be divided into two categories: viscous reversal films with China characteristics and fast reversal films with imported characteristics. China's "sticky reverse glue" has a strong rotating ability when pulling the ball. The new anti-glue can often use its surface "stickiness" to stick a table tennis ball from the desktop, which can stick to the surface of the racket for a long time without falling off. Although the "viscous inversion film" is good, its service life is relatively short. It can be said that the more viscous the inversion film is, the more difficult it is to keep the viscosity lasting. Because "anti-adhesive" is more likely to stick to the environment, including the air and dust on the ball, it will soon lose its viscosity. On the contrary, the imported "quick reverse glue" can keep the friction coefficient of the reverse glue film surface for a long time because the surface is only "astringent" rather than "sticky". It's just that the "quick reverse glue" lacks the toughness protection of the surface "glue layer", so it is easy to be broken, especially the edge part often becomes incomplete during use. Because "sticky reverse glue" and "quick reverse glue" have their own advantages, they can not only be pasted on the front and back of the racket by China players to change the hitting performance, but also be endowed with different hitting functions. Generally speaking, China's "anti-sticking glue" is suitable for taking the initiative to attack by pulling down the spinning ball, while the imported "fast anti-sticking glue" is more suitable for fast stalemate techniques such as opposing attack and pulling. To control these two different characteristics of the "reverse glue" racket, different hitting methods are needed. A world champion said: When using China's "sticky reverse glue" to pull the loop ball, you can directly use the "friction hitting" method, but when using imported "fast reverse glue" to pull the loop ball, you need to change it to "hit first and then rub" because "hit first" can avoid this non-sticking.

2. The vertical and horizontal arrangement of "reverse glue" particles affects the hitting speed of horizontal and vertical strokes.

Secondly, it can be subdivided according to the different particle arrangement of reverse glue. I remember that in the early 1990s, Tianjin Rubber Research Institute introduced a new type of anti-adhesive "Friendship Speed -2000", which was specially designed and produced for world champion horses. Ma is an aggressive crosser. It is said that he used this "back pendulum" and got a good evaluation. However, some backhand players have made different comments after playing this "Friendship Speed -2000" backswing. They think that the so-called "speed -2000" backswing is not fast, even worse than the traditional 729 backswing. It is understood that there is not much difference between the raw material formulas for making two kinds of reverse adhesives. Why do you get such different evaluations? Comparing the particle arrangement on the inner surfaces of these two different types of reflective films, we can see that the inward particles of 729 reflective film are horizontally arranged, that is, its particle arrangement density direction is perpendicular to the direction of the racket handle (see Figure -3 1), while the inward particles of Speed-2000 reflective film are vertically arranged-the particle arrangement density direction is parallel to the direction of the racket handle. From the point of view of hitting friction technology, when the racket holder rubs the ball horizontally with his wrist, the spatial position and action of the racket are obviously different from that of the straight shot. The racket held horizontally rubs the ball forward, upward and inward at the "outer upper part" of the athlete's wrist, while the racket held directly rubs the ball forward, upward and inward at the "outer lower part" of the athlete's wrist. Because the horizontal and vertical strokes of the friction ball are different above and below the wrist position, there is a different relationship between the arrangement density direction of the anti-sticking particles and the hitting direction. The trajectory of the racket's friction action in the cross stroke is almost parallel to the inward direction (longitudinal direction) of the high-density particles in the speed -2000 reflection film, so the elastic speed support of the high-density particles arranged in the longitudinal direction is greater than that in other directions (see Figure -32). Looking at the reversal films produced abroad, the inward particle arrangement direction is almost vertical, which may be because most foreign players hold the racket horizontally. However, the birth of "729" film was almost tailor-made for China backhand players. A year later, at the 1973 World Table Tennis Championships, Xi Enting of China won the singles championship with a 729 "rubber sponge-proof" racket, becoming the first world champion in China to use the "rubber sponge-proof" racket. The lateral arrangement of particles inside the 729 anti-film is more suitable for the backhand racket friction motion trajectory, because the backhand stroke friction motion trajectory under the outer side of the player's wrist is almost parallel to the particle arrangement direction (lateral direction) of the density inside the 729 anti-film, so the lateral arrangement of particles with high density will produce greater elastic speed support for backhand friction hitting than other directions.

3. "Anti-sticking" classification of thick sole leather and thin sole leather

Of course, the factors that determine the classification of the hitting performance of the reflective film are not only the difference between the above-mentioned "adhesion surface viscosity" and "particle arrangement", but also the thickness of the reflective film "bottom skin" (hitting layer). I remember when I was a coach in Pakistan, local athletes were convinced of the 729 anti-film with RITC (Tianjin Rubber Research Institute) logo, and thought that this 729 anti-film was flexible and fast. On the contrary, they think that SUPER-729 produced by Tianjin No.2 Rubber Factory has low elasticity and slow speed. In fact, these two kinds of reflective films all use the same raw material formula and process flow, so there should be no obvious difference. Reason: It turned out that a batch of second-class super 729 anti-adhesive with thin bottom cover flowed into the local market, leaving this impression. On the contrary, Iranian athletes believe in Super 729 film and even give it a higher evaluation than RITC-729 film. 1998 cooperated with jinlu company to test new sponge rubber. We designed a combination of an "ultra-thick" sponge with a thickness of 2.4mm and an "ultra-thin" membrane with a thickness of1.5 mm. As a result, we found that although this thin "bottom skin" membrane combined with a "thick sponge" has a very soft hitting feel and excellent ball control feel, the attack explosion elasticity we pursued is excellent. It can be seen that the adhesive with the same nature has obvious influence on the ball speed after the bottom skin is thin, so the adhesive with thick bottom skin is beneficial to attack, while the adhesive with thin bottom skin is beneficial to chop the ball.

4. Other factors affecting the performance of "reverse glue"

In fact, there are other factors that affect the hitting performance of reverse glue, such as particle size, particle height and particle density. The larger the particle size, the harder the anti-glue feeling when hitting the ball. When the particle size is small, the feeling of "reverse glue" is softer when hitting the ball; The "reverse glue" with higher particles can improve the elasticity of "reverse glue"; The "reverse glue" with shorter particles can make the hitting feeling more "stable"; The "reverse glue" with high particle density is faster than the "reverse glue"; The "reverse glue" with small particle density is more "holding the ball". Of course, the decisive factor lies in the quality of "anti-sticking" rubber. If the quality is not high, all other designs will be greatly discounted or even counterproductive.

5, large particles of "positive glue" to deal with the loop ball

The main reason why "positive glue" can't effectively return the loop ball is the low friction coefficient of granular glue. Proper friction to create the necessary "topspin" is the main guarantee of hitting arc, so "positive glue" players must master the hitting skills of "hitting first and then wiping" at the moment of fast break hitting. Only by "hitting" or "bouncing" the ball first, so that the "positive glue" and the incoming ball can maintain greater pressure, can the incoming ball be effectively rubbed and prevented from slipping out of control. When attacking the ordinary topspin, the "positive glue" racket can effectively overcome the topspin of the opponent's incoming ball with little friction, and at the same time make the topspin needed for hitting the ball, thus maintaining a stable hitting arc and ensuring the hitting rate. I remember that there was a left-handed backhand player Wang on the Beijing table tennis team. In 1963, he won the national championship of men's team for Beijing, and won the national championship of men's doubles in cooperation with Xu Dawan of the same team. As a non-national team athlete at that time, it was a blockbuster to achieve such results in the national competition with many experts. All the players he played against reported that he was a bit of a thief. In fact, the "positive glue" he used at that time was different from what everyone used. A pagoda-shaped glue 12 was stuck on his racket. Because the bottom diameter is large and the top diameter is small, the contact area of the top of the particle is small, the impact friction is small and the particle height is high. But now it is the era of loop ball, which is a powerful topspin ball. Because the arc of friction is obvious, it is called "loop ball". In the early stage of using the "glue" racket to return the loop ball, players usually use the methods of fast push, fast block and fast belt to catch the rising period of the incoming ball and hit the ball with their own strength before the rotation of the incoming ball is completely turned around. Later, when an athlete tries to spin a strong loop ball during the peak period or the falling period, it is difficult, because the friction of the "positive glue" is not enough to completely overcome the strong topspin of the incoming ball, so that the "positive glue" cannot effectively create the necessary topspin of its own hitting arc at the moment of hitting the ball, and it also loses its effective control over the hitting arc. In the athlete's sensory language, the hitting arc is down and the ball can't be hung up. Obviously, the traditional "positive glue" can no longer meet the needs of hitting the ball in the arc circle era. In order to solve this problem, the researchers changed the design, increased the diameter of positive glue particles, narrowed the distance between particles, reduced the height of particles, and improved the friction coefficient of positive glue at the moment of hitting the ball. "Friendship" brand 802 large feature film is designed according to this idea. The successful development of 802 positive glue has solved the problem of "friction" ability of "positive glue" in hitting the ball to a certain extent, and improved the stability of "positive glue" in playing the loop ball. Since then, "Friendship -802" feature film has become the first choice for those who insist on "positive glue" fast break.

Loop ball and anti-sticking racket

Loop ball and anti-sticking racket

Author: Wang Jisheng

In the early 1960s, Japanese athletes invented the loop ball. It is called loop ball because the athletes at that time pulled out a powerful topspin ball with obvious arc with a backhand during the falling of the incoming ball. Before 1950s, the world table tennis was once dominated by Europe. Even at the 19 World Table Tennis Championships held in Mumbai in 1952, after the Japanese team Zuo won the men's singles championship for the first time with its new weapon (sponge racket) and new style of play (forehand and long racket attack), Tsumura and Hotan in Japan also had their own styles. However, it can't change the confidence of European players in their chopping style. In Europe, there is Biercek, a rotary knife that only a crane can pull up, and Sido, a veteran of the 25th world men's singles runner-up. Although it is the rise of the Japanese in Asia, the world table tennis is at best an era of attack and confrontation between chopping and long draw. What really dealt them a fatal blow was that in the early 1960s, famous European chippers formed a United team and went to Japan to participate in an away game. As a result, it was defeated in front of Japan's new loop ball technology. At this time, the 26th World Table Tennis Championships will be held in Beijing. The China table tennis team, which was preparing for the war, quickly got this important message, and immediately sent people to Hong Kong to watch the Japanese game, and soon mastered the first-hand information of loop ball technology. For the honor of the country, many outstanding national players at that time, such as Hu Bingquan, Xue, and Li, gave up their original style of play and volunteered to play iron around the world, imitating the style of Japanese athletes and willing to be sparring partners. At the same time, in view of the weaknesses of curling at that time, such as late hitting time, high arc and slow attack speed, China players carefully prepared techniques and tactics such as serving attack, attacking the ball in the table, backhand attack and quick blocking. At the 26th World Table Tennis Championships, the ambitious Japanese team suddenly discovered that their new technology had no secrets. What shocked them even more was that there were many athletes in China who pulled the arc like them. As a result, in the men's team championship battle, which is regarded as the heaviest gold medal, the classic scene of Xu Yinsheng 12 smash hitting the Japanese team's confidence was finally staged. It is said that Hoshino, the all-Japan champion who lost three points in a row, became a scapegoat, and Seitaro, the coach of the Japanese team who became angry after the game, gave him a slap in the face. Since then, many top Japanese curling players have been defeated by China. Zhuang Zedong, known as "Little Tiger Style", defeated Kenji Kimura, the Japanese team's star of hope, with fierce fast breaks on both sides (this gentleman won China's two points in the team competition). Known as the "bomber", Li Furong defeated Shibuya with fierce sideways and forehand fast break; Xu Yinsheng, known as the "intellectual star", defeated Haruki Murakami with his unpredictable serve and quick lane change. Known as the "magician", Zhang used a long rubber racket invented by China to beat former world champion Ichiro Tsumura with its steady chopping and unpredictable rotation. After Japan, China began to climb to the top of table tennis in the world. Since then, the world table tennis has entered an era of confrontation with different attack speed and rotation characteristics between China and Japan, which can also be called the era of confrontation between near-table fast attack and anti-glue loop attack.

In a sense, the anti-adhesive loop ball technology is a bit untimely. It's because China's fast-break play near Taiwan is becoming more and more perfect and mature, so it is impossible to have enough room for the development of loop ball technology, and China's traditional humanistic environment also restricts the further development of loop ball in China. What needs to be pointed out in particular is that the first generation of curling athletes in China started as sparring partners, and most of these unsung heroes are not superb masters. At that time, the idol worshipped by most young athletes was naturally the leader of the fast break near Taiwan who used the traditional rubber racket, so few people learned this Japanese curling technique that was defeated by China's fast break at an early age. The popularization and promotion of loop ball technology and anti-sticking racket took place in the early 1970s. At that time, a new generation of European athletes had changed their ideas, completely abandoned the traditional chopping style, abandoned defense as attack, and integrated Japanese curling with China's near-table fast break, creating the embryonic form of modern curling fast break technology. Until the end of 1980s, at the World Table Tennis Championships in Montreal, the three Swedish swordsmen-Waldner, persson and Apeyilun finally convincingly defeated their old rivals China with a score of 5: 0, realizing their dreams and regaining the long-lost Swislin Cup for Europe. At this point, it is really a sword for ten years. The modern arc fast breaking technology, which combines speed and rotation, has matured and finally become the mainstream recognized in the world. Since then, reverse glue has replaced positive glue and become people's first choice.

In fact, the attack speed of using the backhand to pull the loop ball is not slower than that of the positive glue. The hitting speed of positive glue fast break is mainly manifested in the fast hitting rhythm near the table, that is, we strive for the rising point and the highest point of hitting the ball, and strive for the initiative with the rhythm speed of combining the landing point with the light and heavy power. In addition, because the coefficient of rubber friction ball is not as good as that of reverse rubber, and the ball plate is thick and hard, the hitting speed is fast and the arc is easy to be flat. Therefore, some foreigners call China's real glue fast break "colorful flag on the stage", as the name implies, it is to gain time advantage by playing fast, with a flat arc and short distance. However, the modern fast loop ball attack technology using backhand can not only hit the rhythm speed of the positive glue and the flying speed when hitting the ball vigorously, but also create a strong topspin when attacking, so that the ball can move forward or arch after landing, resulting in acceleration and speed change that the positive glue does not have. In other words, in the same recent attack, reverse glue has one more speed winning factor than positive glue. Even in the off-stage attack that loses rhythm and speed, the reverse glue can still maintain the fast flying speed and the acceleration and speed change of the forehand, which are not easy for the positive glue racket to do. Because the anti-sticking racket has many speed advantages, it is the inevitable result of the development of table tennis technology that most people choose the anti-sticking racket.

People who use reverse glue rackets are often troubled by the service life of reverse glue. Unlike reverse glue, reverse glue rackets sometimes have a short service life. Generally speaking, even if it is well protected, it will only take 3-4 months at most. But there are exceptions I met an American old man who loves table tennis in Beijing this summer. He treasures his racket very much. According to him, he insists on practicing more than three times a week, and each time it is more than 1 hour. However, his anti-sticking racket has been used for two years, and it seems to be new. It turned out that he specially made a plexiglass racket clip for his racket. After each use, he will clean it with a special racket face cleaner, and then clamp the anti-sticking surface with a racket clip to isolate the anti-sticking from the air. In order to prevent the racket clip from separating from the racket, he also installed bolts at the four corners of the racket clip. The old man never allows others to touch the anti-sticking surface of his racket casually. Indeed, his racket is very well protected. According to rubber experts, rubber molecules are intertwined like lines. After vulcanization, sulfur molecules and rubber molecules will be arranged in an orderly manner. A new type of anti-sticking agent with good surface friction coefficient is mainly caused by the short head and gap of rubber linear molecular arrangement. However, the release agent becomes non-stick for two main reasons. First, the gaps between anti-sticking molecules are filled with dust and debris, which makes the anti-sticking surface physically change. Another reason is that the anti-sticking molecules further react with chemicals in the air, which leads to chemical changes on the bonding surface. According to the above principle, as long as you keep the playing environment clean and sanitary, and at the same time carefully protect your anti-adhesive racket like that old American man, the anti-adhesive life will definitely last longer.

Experience of turning and not turning to serve

Experience of turning and not turning to serve

My forehand backhand turn and non-turn are both successful. Although my overall level has not reached the level of top amateurs, many of my servers are hungry. Ordinary amateurs can learn from it. Don't laugh at the master

1, absolute rotation must not be emphasized in serving, because no matter how the ball rotates, it will be useless as long as the opponent sees it. Be sure to let your serve exceed your opponent's judgment. The more unexpected it is, the more effective it will be. The really good strong backspin is that the lighter the action, the more turns.

So, when you have a strong backspin, you can't go all out. You can't cooperate with your whole body like a high wind, although it's easy to make a powerful rotation. But every part of your body exposes the rotation of your ball to each other (except for the fake action). Therefore, the strong downward rotation is dominated by the wrist, supplemented by the forearm and slightly driven by the waist. Maybe you will say, it's all sent like this. But my experience here is that if you want to go far beyond your opponent's judgment, the whole service should be soft and not even hard. For example, backhand backspin can be done by gently moving your wrist, even without shaking your wrist, because once you find that you are shaking your wrist, it is easy for the other party to judge your backspin. And if you serve hard, the ball will float very hard, and it is easy for the opponent to judge from it. And you seem to be inadvertently issued, it is difficult for the other party to see that you issued a strong downward rotation. However, how to make a strong downward rotation without exerting force or even moving slightly is a level. This requires touch. Friction doesn't have to be fast, but it must be enough. It doesn't matter whether the ball is thrown high or low, but the thickness of friction must be controlled. This kind of friction is the absolute key, and the whole service process is completed in a fairly relaxed situation, and it is absolutely impossible to shake it hard and quickly. Be sure to try to be gentle and slow. In addition, be sure to wipe it to the lower center of the racket. It is also the key. F 1 rubber is the best for hair, because f 1 belongs to internal energy type. In this way, the slight friction of the rubber will automatically convert the energy of throwing the ball into the rotational energy of the moment of friction. I almost used crazy 3. Let's practice this full hand rubbing and rubbing time slowly, but never fast. The backspin I am sending now is not a spin at all in the eyes of others, but it is actually quite strong, and even many people think it is more spinning than the sharp backspin that most experts are trying their best to send. This contrast is big enough. This is the case when the service is good to a certain extent. Of course, my serve is far from the national team's backspin. But my serve is similar to theirs, except that the feel of friction is much better than that of ordinary people. Anyway, you must never think about how strong your backspin is. The really good backspin is that the lighter the action, the more turns. That hard downward rotation is useless to the master.

2. The same action will not start.

If you can make a backspin that is far beyond the opponent's imagination with a light action like me, then you can serve like an ordinary person with the same action, that is, a person with poor serve, that is, a person with poor friction and bad hitting time. Of course, this kind of service is not very good, and opponents will eat it. If you change the hitting point on the racket again, use the top edge or leading edge of the racket to serve, but the racket face should be flat when serving, so that the opponent can't easily see it. In this way, even the master can eat the ball. If you use some shaking and full body strength to match the hair, other things will be more easily eaten by your opponent. Maybe someone will ask, didn't you say that you can't use the whole body coordination and wrist jitter to make a strong downward rotation? You can't spin the ball. Why are you doing this? The reason for this is that if you add jitter and whole body, the absolute speed of downward rotation is of course higher. But if you want to serve the backspin, it is easy to be seen, and the opponent who can't serve the ball is more likely to be considered as a strong backspin, the better. Of course, sometimes it should be noted that it is empty and empty is real. Now many people judge that my serve is basically a guess. They know I don't push hard, but my movements are usually sharp backspin (it's not easy to see from my ball hitting). Because my serve really looks slow but doesn't float, you can see it by looking at the logo, but sometimes it seems difficult for me to serve faster, and I can serve slowly by looking at the logo, at least in time), so when I serve with a really strong backspin, they will regard it as a slow catch, which is really dazzling, so I have to occasionally do a few really strong backspins with an ordinary strong backspin. In this way, their chances of being cheated are not high. However, it is better to practice serving a ball with great rotational contrast with ordinary slow movements. Because this kind of thing depends on the change of feel. Rather than a simple change in the hitting part. When the hair doesn't turn, the smaller the change of the hitting part, the better. Don't be too close to the edge of the racket, which makes it more difficult for the opponent to see clearly, but it is also difficult to have a strong contrast. Once you develop a sense of touch, the initiative is entirely on your own side, because the change in the feeling of hand friction is invisible to the other person's eyes. Only one's own proprioception can feel the change of this friction. Basically, it is a bit thick and thin and the timing of friction, the feeling of friction and so on. It's hard to tell with the eyes. This is also the reason why many of my serve masters are very confused now. They can't figure out why I have such a strong rotation with a light shot, but sometimes I don't turn at all. This is kung fu and level. I usually rub my hands well, so I also rub my serve well. I suggest that if you want to improve your serve, you should also improve your serve. After all, we have to rub the ball many times every day. Multi-use is the premise of good practice.

In addition, the speed and impact point of the ball have changed greatly. For example, the forehand position can occasionally serve like this, and he is ready to let his opponent pull it. If he can't judge the mistake correctly, the chances are quite high. I serve now, even if the opponent judges the backspin, it's not easy to pull it up, because now amateurs pull forward and generally have a great chance of making strong backspin mistakes like me, so it's better to pull it up and hang it, but those who are afraid of not turning around sometimes dare not lift it hard, which is a headache. With the same preparation action, suddenly two big corner kicks came over. The backhand sends a bigger angle. The pressure on the other side is even greater.

Well, I've told you all about my experience. Whether I can serve depends on your efforts. I hope that some server experts will criticize and correct me.

What are the characteristics of positive glue, reverse glue, long glue and raw glue?

What are the characteristics of positive glue, reverse glue, long glue and raw glue?

Rubber used for sticking rubber particles outward is considered as positive rubber. Because the rubber particles are outward when sticking, the rubber particles are directly impacted by the ball and produce elastic deformation (the deformation degree of the same rubber particle is different because of the different speed and strength of the incoming ball). The greater the deformation, the greater the instantaneous resilience and the faster the return speed, but its disadvantage is insufficient rotation. Long rubber, as a special rubber particle in cathode rubber, is long and soft with good toughness. When inclined to one side, the loop is erratic and the ball sinks. Known as "magic rubber particles" in the industry. Raw rubber is a kind of rubber between long rubber and positive rubber, and its performance is also the best of the two. It has the characteristics of long rubber particles preventing rotation and hitting the ball, and it also has the advantage that positive rubber particles are good at fast attack.

Rubber particles stick inward and can be used as reverse glue normally. Because the particles on the rubber surface are extruded and deformed at the moment of hitting the ball, the elastic deformation of the particles increases the rebound strength of the rubber surface and improves the ball speed. Compared with the positive glue, the reverse glue has a larger friction surface, which increases the friction and enhances the rotation.

Basic knowledge of table tennis-several basic steps

Basic knowledge of table tennis-several basic steps

1) step by step.

1, the moving method takes one foot as the axis, the other foot moves in different directions, and the body center of gravity falls on the moving foot.

2. Practical application: ① Close to tennis; 2 cut and chase the ball; ③ One-step sideways attack is often used when the incoming ball falls slightly to the left of the center line, or when the ball is pushed sideways or pulled in the middle.

(2) stride

1. moving method: when one foot is on the ground, the other foot takes a big step in the moving direction, followed by half a step or a small step, and the center of gravity of the body moves to the foot.

2. Practical application: ① Near-table fast break, which is used to handle the incoming ball slightly away from the body; (2) Chopping the ball and hitting the ball by moving it left and right; (3) Step sideways attack: When the incoming ball is slow but slightly away from the body, the left foot takes a big step to the left, and the right foot immediately takes a small step, and at the same time cooperates with the waist to turn right to complete the sideways action.

(3) step by step

1. moving method: first move one foot to the other for half a step or a small step, and then move the other foot to the ball immediately after landing.

2. Practical application: ① Fast break players attack or pull the ball while moving left and right; ② Chopper's forehand and backhand chop; (3) Step by step sideways attack, mostly used for pulling and chopping. The right foot first moves to the left foot, then steps to turn, and then the left foot moves to the side.

(4) Jump

1. Self-moving method, the foot on the other side of the ball hits the ground hard and both feet jump in the direction of the ball at the same time.

2. Practical application: ① Fast-break players move left and right to hit the ball, which is often used in conjunction with the stride; (2) When the intermediate platform moves left and right, it is usually played with loop ball; 3 jump sideways to attack or pull, but you need to complete the waist-turning action in the air; (4) Choppers are often used when receiving an assault, but small jumps are often used to adjust the position.

(5) Take a step

1. The moving method uses the foot close to the incoming ball as the supporting foot, and adjusts the toe to point to the moving direction. The foot far away from the direction of the incoming ball crosses in front of the body and takes a big step in the direction of the forward ball, then the body rotates in the direction of the forward ball and supports the foot to take another step in the direction of the forward ball. This is a step forward. The back cross step is to complete the cross action behind the body.

2. Practical application: ① Fast break or loop ball is used for sideways attack, and the right corner is played after pulling, or the right corner backhand stroke is changed; (2) Cutting the ball while walking; (3) Chop the ball to catch the short ball or chop the highlight.

Four basic factors affecting table tennis skills

Four basic factors affecting table tennis skills

There are many different ways of playing table tennis and many tactics. No matter what style of play, no matter how changeable tactics, table tennis skills are inseparable from four basic factors, namely strength, speed, rotation and placement.

Power acts on the ball, which is manifested in the forward speed and rotation intensity of the 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.

If you are strengthening the spin, whether it is topspin or backspin, then you must rub the ball hard.

In order to minimize the opponent's preparation time, you 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. This is speed.

In order to increase the difficulty of the opponent's counterattack, we can also make all kinds of spinning balls to force the opponent to "give a chance" after returning the ball. This is rotation.

The table tennis table is not big. To make your ball more powerful, you must mobilize your opponent to move or run back and forth. So pay attention to placement.

Therefore, strength, speed, rotation and placement are the basic elements of table tennis technology.
