How to correctly judge the spin performance and strength of a table tennis ball

The first thing to do well in table tennis is to judge. To judge the spin, you need to pay attention to the ball: from the moment your opponent tosses the ball, you need to focus on the ball. What to keep an eye on?

1) Staring at the ball. Is the opponent a high or low toss? For example, if you also send a downward spin, a high throw will be more rotated.

2) Staring action: Does the opponent hit the ball more or rub more? There are many impacts, and the ball that comes over is generally faster and more rushing, but it will not spin very much; If there is more friction, the rotation is strong and the speed is slow.

3) Keep an eye on the trajectory. The trajectory of the ball is the best expression of spin. After the opponent serves, the ball turns in the middle of running, indicating that there is side spin; After the opponent serves, the ball does not turn, the arc is short, the movement is slow, and the logo of the ball can be seen, indicating that the ball does not rotate or spins very weakly.

After the opponent serves, the ball is unrestrained and fast, and the arc is very long, generally a running ball, which will be out of the table, and can be pulled sideways directly or backhanded.

4) Also keep in mind the opponent's serving habits. Some people will only have one or two sets of serves, you eat a few and you will know, and the next time he serves the same ball, you will take it. Some people's serve action is deceptive, and it seems that the same action but makes different spins, in fact, if you look closely, there will be differences, such as:

Some people have similar sideways and side-down movements. However, the side must give the ball a downward tangential friction, and after the friction is completed, the action will be deliberately retracted into the arms, confusing the opponent and making people mistakenly think that it is on the side. In fact, this action must be incoherent in the middle, at least not as coherent as the side of his hair directly.

You can judge by the opponent's hitting action and the trajectory of the table tennis ball.

However, for novices, it is useless to say 10,000 sentences, it depends on practice.

Making accurate judgments about the spin of table tennis balls is extremely important for amateur players to receive serves. From the perspective of ball nature, there are three types of rotation of the serve: one is the up-and-down spin (side spin, counter-spin) serve; the second is to turn and not ** the ball; The third is the sudden rush of the long ball (side rush, flat rush).

As long as you stare at the ball and the touch of the racket at the moment of contact, you can judge what type of ball it is, and other tricks are sudden. The skills of its judgment are:

1. From the perspective of the plate type, the flat ball rubs the lower half of the ball, which must be downspin (left and right side down); If the ball is upright and touches the ball in the middle and upper part, the ball must be topspin (left and right side up) or non-spinning ball.

2. From the point of view of action (direction), the ball cut down in the direction of the serve must be a ball with strong downspin, and the more you go down, the more you turn; The ball that is pulled up in the direction of the serve must be topspin or non-spinning. Sometimes a backhand is used to issue a counterspin.

3. From the arc point of view, the ball with a low arc is generally downspin; Balls with high arcs are generally topspin.

4. From the point of view of speed, the slow movement speed of the ball is the downspin ball; The fastest movement of the ball is the topspin ball. In special cases, it's the opposite.

5. From the point of view, the first landing point near the net is a short ball; The first to land on the baseline is the long ball.

6. Judging from the instantaneous violence and changes in the plate shape, the ball that suddenly rushes forward with the plate type is a sharp downspin; The ball that suddenly rushes forward is a sharp topspin, and the ball that hits a little heavier does not spin.

Judging the spin of the opponent's serve can greatly reduce the number of errors in receiving the serve. The purpose of receiving the serve is first to receive the serve well and strive not to "eat" the ball; the second is that the opportunity comes to receive the serve and attack directly; The third is to control the rotation of the opponent's serve, which can greatly reduce the mistake of receiving the serve. The purpose of receiving the serve is first to receive the serve well and strive not to "eat" the ball; the second is that the opportunity comes to receive the serve and attack directly; The third is to control the landing point and rotation of the return serve to prevent the opponent from serving and attacking.

That's why it's so important to correctly judge the return spin. The landing point and rotation of the receiving serve prevent the opponent from rushing to serve. That's why it's so important to correctly judge the return spin.

The smartest way to judge what the opponent will serve (landing, speed, spin, arc, rhythm, power) is to guess the ball and count the opponent. Of course, this is not to say that it is a blind guess, but to have a well-founded guess.

This guess, on the one hand, is based on your previous knowledge of the opponent, what stage of the game they are in, what kind of serve they like to use, and what is the proportion of data.

On the other hand, from the perspective of this game, you have to analyze what kind of ball the opponent serves more, and whether there is any pattern to be found.

The first skill is that the speed of his whole spin is very powerful, the second skill is that he has a special process in the process of spinning, and the third way to judge the skill is to see how fast the pitch is at that time.

It can be judged by the way the table tennis ball is hit, if the table tennis ball is hit from above, then it is an upspin ball.

Table tennis spinning ball technology is the most important and basic technology of today's table tennis sports, the spinning ball has many changes, the landing point is complex, and the characteristics of the route may change after touching the racket are widely used by players. Below I have collected and sorted out the judgment essentials of table tennis spinning ball for you, I hope it will help you!

The essentials of judging the spinning ball of table tennis1.The kanban shape determines the nature of the ball

Under normal circumstances, when the topspin ball is served, the plate shape is relatively vertical, and the downspin ball is relatively flat and oblique, and this characteristic is directly related to the part that should contact the ball when serving, because when the ball is rotated and the ball is not rotated, the contact point is relatively close to the back middle of the ball; When the hair is topspin and downspin, the friction to the middle and lower parts and the bottom may be more turned;

2.Judge the nature of the ball by the opponent's shots

Topspin and non-spinning shots are generally fast, and suddenly, the action is blurred; The shot of the downspin ball is relatively slower because the ball needs to be rubbed enough time to produce a strong downspin effect.

3.The nature of the ball is judged by the trajectory of the movement

When the ball is sent downspin and does not spin, the moment the ball makes contact with the racket, the amplitude of the wrist swing is generally not very large, and it is often matched with feints; When the topspin and downspin are added, the wrist swing is relatively large, so that it is easy to "eat" the ball, and the action is relatively fixed, and there is often a pause after hitting the ball, even if the feint is added, it will not be as coherent as the topspin and non-rotation of the ball;

4.The nature of the ball is judged by the flight path

Upspin and non-spinning. The operation is generally relatively fast, and there is often a feeling of "arching" forward, and it is easy to come out when sending short balls, and the arc is low and flat; The downspin ball runs relatively smoothly, the arc is slightly higher, and the short ball is not easy to come out;

5.Pay attention to the opponent's serve pattern and judge the nature of the ball

When receiving the serve, it is also important to constantly ponder the random distribution and habits of the rotation nature of the ball sent by the server, especially when the judgment is not clear, such as in a round of serve, the server generally has a few turns, a few non-turns, a few sides up, a few sides down, usually appear in a round, as well as what kind of ball is loved at the beginning, how to send the key ball, etc. There is no doubt that in the face of the new and unpredictable serving techniques in the world table tennis today, the guess of the receiver is indispensable, and it is not practical to make every ball clear.

In addition to being the fastest ball game, table tennis is also the ball game with the strongest spin. Because of these two characteristics at the same time, beginners are often at a loss. Spinning, in particular, makes beginners suffer enough.

This time, let's talk about the classification and effects of rotation.

One. The rotation of a ping pong ball.

Let's imagine that there is an axis of rotation passing through the table tennis ball, and the direction of our rotation is named after the axis of rotation. When the axis of rotation is horizontal, take yourself as a reference and turn it back (clockwise with your left hand), which is called downspin. Conversely, with yourself as a reference, turn forward (left hand counterclockwise) to topspin.

When the axis of rotation is perpendicular to the ground, when viewed from the top of the ball, clockwise rotation is left-hand rotation and counterclockwise rotation is right-hand rotation. When the axis of rotation is perpendicular to yourself, from your direction, the clockwise rotation of the ball is forward rotation, and the counterclockwise rotation of the ball is reverse rotation, which is determined by the different friction directions of the racket.

Two. The naming of the rotation.

The naming of rotation is ideal, and in practice the axis of rotation may be in any direction. So the real spin of a ball is often a compound spin of several spins. For example, the forward and reverse spin mentioned above require the racket to be completely flat and rub the ball horizontally to the left or right, but in this case, the ball does not have the power to move forward.

Therefore, it is often necessary to stand up the racket a little, and at this time, it is often necessary to bring a little side spin to form a compound rotation of two spins. At this time, it is divided into two situations, the first is that one of the rotations occupies the main body, which is much larger than the other rotations, and we will approximate what it becomes rotation. For example, if the topspin has a piscalous land point deviation and a little side rotation, we still call it topspin.

The second is that the two rotations are comparable, the proportions are about the same, and at this time even read, for example, there are topspin and sidespin, we call it side-topspin.

Three. The effect of rotation.

Upspin: Because of the rotation of the ball, the air flow above is slower, and according to Bernoulli's principle, a downward pressure will be generated, so that the topspin ball will land earlier than the non-spin ball; After landing on the stage, due to the rotation, it will accelerate forward and move forward, and it cannot jump as high as the spinless ball; After the opponent receives the ball, the ball will roll upwards and it will easily fly.

Downspin: Contrary to topspin, there will be an upward support force, so that the downspin ball will delay the landing of the ball relative to the non-spin ball; After landing on the table, contrary to the topspin, there is a backward force, so that the downspin ball cannot jump as high and so far as the spinless ball after landing on the table; After the opponent receives the ball, the ball will roll down and may go into the net.

What is it called, after the opponent receives the ball, the ball will run in that direction. If your opponent hits a topspin ball, you press the racket down and press it down; If your opponent spins, you set the racket flat a bit. The same is true for left and right side rotation.

There are 6 types of rotation in table tennis ball: left-handed, right-handed, forward-spin, topspin, downspin, and backspin. Each corresponding effect is different, and Sun Jing must learn under the guidance of a professional coach, and the progress will be faster.

Defining the axis of rotation is of great significance to rotation. One rotation with one and only one axis of rotation! One axis of rotation with and only 2 types of counter-rotations!

Judging the incoming ball is the first part of playing table tennis, and it is the basis for determining the movement footwork and hitting technique.

1.The main way to determine the route of the incoming ball:

a.Determine the route of the incoming ball from the direction of the paddle face when the opponent hits the ball. Generally speaking, when the opponent's racket touches the ball, the direction of the racket face is the opponent's contact route, for example, when the opponent hits the ball on the forehand side, when the racket touches the ball, the racket face is facing the right corner of the opponent, which is a slash ball; The paddle face is facing the left corner of the face and is a straight ball.

b.The path of the incoming ball is judged by the position of the top of the net. For example, if the opponent hits the ball on the forehand side, the ball crosses the middle or right side of the net, and the ball will fly to the right side of his table; The incoming ball crosses the left side of the net and the ball will fly to the left corner.

c.Depending on where the ball lands, you can determine the route of the incoming ball in advance. For example, if the backhand presses the opponent's backhand diagonal ball at a large angle, it is difficult for the opponent to return the straight ball, and the return route is generally in the left half of the table or in the middle of the table.

2.Determine the spinning nature of the incoming ball:

a.The spinning nature of the ball is judged according to the actual swing force direction and the position of the ball when the opponent hits the ball. If the opponent swings the racket from top to bottom, it is mostly a downspin ball; Swing the racket from the top left to the right down, mostly downspin.

b.According to the size of the opponent's force and the thickness of the friction when hitting the ball, the strength of the rotation of the incoming ball is judged. The opponent's swing and rubbing the ball have a large range of action, fast swing speed, and thin friction, so the incoming ball spins strongly, and vice versa.

3.Determine the landing point of the incoming ball: The landing point of the incoming ball can be judged by the force of the opponent's stroke.
