Table tennis is a sport with many styles of play. Because of different types of play, their basic skills are also different.

Basic technology is generally divided into single technology and combined technology. Single technique refers to all kinds of single technical movements, which beginners must master carefully. Combined technique refers to the combined application of various single techniques, which is the basis of tactical training and application.

The grip method is closely related to the hitting action. Every stroke is done through the cooperation of arms, wrists and fingers. Therefore, a better grip method should not only suit the characteristics of playing ball, but also affect the flexible use of arms, wrists and fingers.

There are two ways to hold the racket: the straight racket and the horizontal racket. These two grips are different because of their different playing characteristics.

First, the direct grip method

(A) Fast-break grip method

There are three common grip methods for fast attack types (including left push and right attack and double attack):

1. The right side of the racket handle is attached to the third joint of the index finger, and the second joint of the index finger presses the right shoulder of the racket. The first joint of the index finger naturally bends inward, and the first joint of the thumb presses the left shoulder of the racket (the distance between the thumb and the index finger should be moderate). The other three fingers naturally bend, bend and skew, and the first knuckle of the middle finger is supported on the back of the racket to keep the racket stable.

This grip is more flexible. You can use your wrist to serve a ball with similar movements but different rotation points; You can also play the oblique straight ball very flexibly; It is also advantageous to handle the ball in Taiwan Province. In backhand position, hitting the ball with backhand and then hitting the ball sideways with forehand is beneficial to the coordination of forehand and backhand movements. For chasing the ball in the middle, the wrist can droop naturally, and the shape of the racket can be adjusted by the wrist to return the ball reasonably. When using this grip method in forehand attack, the thumb and middle finger coordinate their efforts, the index finger is relatively relaxed, the ring finger is slightly away from the middle finger, and the fingertips lightly support the back of the racket to maintain the stability of the racket when exerting force. When backhand attack or putting the ball, the index finger and middle finger coordinate their efforts and the thumb is relatively relaxed. When using the wrist (including forehand and backhand strokes), the middle finger is the main force, and the thumb and forefinger keep the shape of the racket stable, and at the same time act as the auxiliary force.

2. The grip method is basically the same as the first one, except that the distance between thumb and forefinger is larger (pincer shape is larger). This grip is beneficial to the concentration of upper arm and forearm strength. Therefore, attacking from COSCO Taiwan, forehand attack and smash are all more powerful. However, due to the large distance between thumb and forefinger and the deep grip, it has a certain impact on the flexibility of wrist, which is not good for handling the ball, turning the ball, pushing and blocking the ball and chasing the ball in Taiwan.

3. Stick the right side of the racket handle between the second and third joints of the index finger, and press the left and right shoulders of the racket with the first joints of the thumb and index finger, with the distance between the two fingers being moderate (but smaller than the first grip). Use the left side of the first knuckle of the middle finger to support the back of the racket, and the ring finger and the little finger are obliquely stacked under the middle finger, and use the ring finger to assist the middle finger to support the back of the racket to maintain stability.

This grip is adopted by some players who attack from both sides. Its advantage is that in backhand attack, the forearms are raised and the racket head is upward, which is beneficial to backhand high-pressure play and makes the shot fast and powerful. This grip is more harmonious when hitting the ball in the middle, because the racket hangs down when sinking the hand. Because the distance between the thumb and forefinger is small and the wrist is flexible, it is easy to handle the ball on the table, which is also good for the sudden rotation of the ball. Its disadvantage is that the racket is drooping and it is difficult to hit the ball with high pressure. At the same time, due to the flexibility of the wrist, the shape of the racket is not easy to fix.

(2) Arc grip method

There are two types of grips, the straight grip and the ring grip:

1. The grip method is the same as the first grip method of fast attack type. When it pulls the loop ball forehand, the thumb, middle finger and ring finger coordinate their efforts, and the middle finger and ring finger are slightly straight (not completely straight, but there are still some bends) to better keep the racket forward when hitting the ball.

The advantage of this grip is that the wrist is more flexible, the forehand, backhand and push block are easier to cooperate with, and the ball in the table is better. The disadvantage is that the racket type is not fixed, and it is difficult to deal with large-angle forehand and high smash.

2. The thumb is attached to the left side of the racket, and the index finger gently buckles the handle to form a small ring. The middle finger and ring finger hold the back of the racket straight with the first knuckle, and the little finger naturally clings to the ring finger. This method of holding the racket naturally connects the arm, wrist and racket into a line, and the racket is horizontal, which expands the care scope of the right half table. It is easy to exert the strength of the arm when the forehand pulls the loop ball to smash. When forehand and backhand are combined, the wrist is mainly driven by the forearm to make a circuitous movement. The disadvantage is that the wrist is not flexible and it is difficult to deal with the backhand near the fast break ball, billiards, chasing the ball and billiards.

(3) Chopping backhand chopping grip is that the thumb naturally bends and clings to the left side of the racket handle, the first knuckle presses down hard, and the other four fingers naturally hold the racket back respectively. This grip takes care of a large area of chopping, and the shape of the racket is adjusted by the rotation of the arm during forehand and backhand chopping. When chopping the ball, the index finger should move forward quickly, and the second knuckle should press the right shoulder of the racket; After the racket, the three fingers naturally bend and hold the bottom of the racket.

Second, the horizontal grip method

Offensive (including fast break and loop ball) and defensive (including the combination of cutting and attacking) grip is basically the same. But it can be divided into shallow grip and deep grip.

Hold the handle naturally with the middle finger, ring finger and little finger. The thumb is lightly attached to the middle finger on the front of the racket, the index finger naturally stretches and inclines to the back of the racket, and the tiger's mouth is slightly attached to the racket. Deep grip and shallow grip are basically the same, except that the tiger's mouth is close to the racket. In these two grips, the index finger should use some force when hitting the ball forehand, and the index finger can also be moved up to help the racket. When backhand attack or fast dial, the thumb should use some force, or you can move the thumb up to help beat. When you chop the ball forehand and backhand, your fingers are basically motionless.

The advantage of shallow grip is that the grip is loose and the wrist is flexible. There are many ways for Taiwan Province to handle the ball, such as pulling, skimming and swinging short. When attacking, it is easier to bounce the low ball. The combination of left and right is more flexible and coordinated. When chopping, rubbing and serving, the rotation changes little, and the opponent is not easy to judge. The disadvantage is that it is difficult to concentrate all the strength of the upper arm and forearm on the wrist when attacking, so the force is slightly affected. When cutting the ball, the shape of the racket is not easy to be fixed because of the flexibility of the wrist, especially when cutting the arc ball.

The advantage of deep grip is that the grip is tight and the racket shape is relatively fixed. When attacking, the strength of the upper arm and forearm can be concentrated on the wrist. Pull up the hook, the forward curve ball is more violent, and the smash ball is more powerful. The curve ball is easier to control, and the spinning ball and chopping ball are more powerful. The disadvantage is that the wrist is not flexible enough because of the tight grip. When attacking, the flexibility of combining left and right is slightly poor. It is more difficult to handle the ball on the table. It is more difficult to play forehand. It is difficult to deal with the short ball on the right side of the middle road when cutting the ball. The difference between chopping and not turning the ball is obvious, which is easy to be seen by opponents.

Operation skills of new service rules

ITTF adopts new service rules in international official competitions, that is, the open service that people care about. It means that when an athlete serves, at the moment when the ball touches the racket, there should be no obstacles in the virtual triangle formed by the connection between the hitting point and the net posts on both sides and above a certain height, and one of the referees should be able to clearly see the hitting point of the athlete. Through the literal understanding of this rule and the practice and exploration of China team for a period of time, it is preliminarily felt that the following aspects should be paid attention to in order to serve the ball that meets the rules without destroying its structure.

1, the thrower is below the hitting point. It turns out that most of the players' serve and hitting points are above the thrower or basically on the same level with the thrower, which causes the thrower to block the hitting point and can't see the hitting state in front and the referee's position. In order to meet the requirements of the new rules, the thrower should leave the front of the hitting point as soon as possible after throwing the ball. In practice, I feel that it is more natural for the thrower to serve under the hitting point than to move to other places.

2. The throwing route should not be too oblique. At present, athletes tend to throw the ball obliquely to the inside of their bodies when serving. This is convenient to hit a high-quality spin ball, but it also causes the body to block the hitting point, especially the sideways serve. In the operation required by the new rules, throwing the ball should not be too far back, and it is generally easy to be seen near the longitudinal axis of the body. Of course, like most backhand serve and squat serve, it will be very clear to put the hitting point on the front of the body.

3. The angle between the body position and the end line of the table is less than 180 degrees. If the angle between the two feet and the end line of the table is about 180 degrees when serving, it is difficult for people to see the hitting point in any case under the existing conventional service state. It is best to keep your feet at an acute angle with the end line of the table before serving, so that the probability of the upper body blocking the hitting point will be much smaller and the safety factor will be much larger.

4. Don't lean forward too much. When serving, the body leans forward too much, and even some players' upper bodies are almost on a horizontal line with the table, which is particularly easy to cause the shoulders to move too late to cover the hitting point. Therefore, when serving, the upper body should be straight and slightly forward, and the angle between the upper body and the lower body should be at least 100 degrees, so as to ensure that people can see the hitting point clearly to a greater extent.

5. Move the hitting point down appropriately. If the hitting point is close, it is easy for the chest to block the hitting point because of the untimely rotation. When serving, it is best to hit the ball at the height of the abdomen. In this way, because the rotation has relatively little influence on the clarity of the hitting point, it is easy for people to see the hitting point when serving.
