Why is the topspin so stable?

It's a simple physical phenomenon. Upspin the ball, sink more when pulling the racket, wrap the ball from bottom to top, so that the ball is rotated up after going out, it is an obvious arc in the air, the height in the air is relatively flat and the height of the ball over the net is high, so it is not easy to go down the net, and it falls rapidly after crossing the net, and it is not easy to go out of bounds. So it's stable, but because of that, the ball loses the speed of a flat hit.

The name is called topspin ball, it must have a very strong spinning plug, the ball will be subject to greater air resistance due to strong rotation in the air, and the ball speed will not be too fast due to air resistance, so after such a ball rises to the highest point, it will also fall quickly, so it is not easy to get out of the bottom line.

On the other hand, the flat shot spins less in the air, is subject to high air resistance, and flies fast! It is not possible to ensure a stable landing in bounds like topspin.

..I don't know what level of topspin is very stable, but I know that the topspin ball is fast (relative to the downspin ball), the landing point is relatively fixed, not easy to go out of bounds, and it is easy to control the landing point compared to the flat shot, which is a more popular way to hit the ball.

The rhythm of the topspin is relatively fast, the offense generally uses topspin and flat shots, and the topspin is more comprehensive, and the downspin ball is generally slowed down for defense, or the ball is adjusted to a small ball and side spin.

It's not easy to hang up the net when you pull the topspin ball, it's not easy to go out of bounds, in fact, you can see the stability of the topspin ball when you look at Nadal's play :)

Summary. Upspin Ball: A ball that spins quickly in its own direction. Features: Fast speed, touch the table to accelerate and bounce up and high bounce amplitude, touch the racket will float upward. When you catch the spin ball, you need to press down, otherwise it will be hit.

Downspin: A ball that spins quickly towards the opponent. Features: The speed is slow, the bounce amplitude is low when touching the table, and when you touch the racket, it will accelerate down the line. To catch the spin ball, you need to apply force upwards, otherwise it is easy to touch the net.

What is a topspin ball? What is Downspin Ball?

Topspin Rules: A ball that spins quickly in its own direction. Features:

The speed is fast, the touch table accelerates and bounces up and the bounce width is high in the world, and the touch of the racket will float upwards. When you catch the spin ball, you need to press down to the bottom of the limb, otherwise it will be hit. Downspin Ball:

A ball that spins quickly towards the opponent. Features: The speed is slow, the bounce amplitude is low when touching the table, and when you touch the racket, it will accelerate down the line.

To catch the spin ball, you need to apply force upwards, otherwise it is easy to touch the net.

Hope mine is helpful to you.

The topspin ball is characterized by fast speed, not easy to receive, if it is a short ball, it is not easy to control, and it is easy to catch high after a mistake in judgment, and it is easy to be attacked by the opponent. No Push: On the backhand, you can swing short to the opponent's forehand and stick the tennis ball to return the difficulty to the opponent.

If the ball is fast and not easy to control short, the horizontal shot will be picked with the backhand, and the straight shot can be pushed with the backhand to block the angle. The forehand position, the split is long to the opponent's backhand large angle, or the opponent's forehand position is directly provoked by the large angle, the latter is more positive, but if the opponent turns back, it is not easy to deal with, so prepare in advance for the next catch. In the middle position, the horizontal shot can be twisted up with a backhand in the stage, with a slight pick.

Straight shots are sideways and provoked with a forehand to attack. Push-out or semi-push-out: Backhand, horizontal shot directly hit or quick dial, but pay attention to the control angle, not let the opponent easily attack.

Forehand, stride to hit the opponent's forehand at a large angle or the opponent's backhand, and try to increase the speed of the ball. In the middle, take the initiative to use the forehand sideways, play more and play less, and use the arc ball to increase the rotation of the ball, especially when the arc of the ball is low, which can ensure the rate of getting on the stage and reduce mistakes. The enhancement of rotation undoubtedly makes the opponent dare not exert force easily.

First: close to the table to attack, return the ball at a faster speed Second: slightly back from the table, pull back the third: retreat from the table to cut the ball, but there is a greater difficulty, you need a professional chipper.

Technology to a certain temperature, as the saying goes, one evil controls evil.

Push it over with the angle of the lower shot appropriately.

Use the elimination method to judge the upper and lower spin, that is, all the moment when the racket touches the ball, the paddle surface leans back and there is a downward or sideways action.

Upspin ball: 1. Don't lead the racket to the bottom, swing the racket from the side and back, the hitting time is the rising period or the high point period, and press the ball as soon as possible.

2. When pulling the topspin, the plate type should be leaned forward as much as possible, and the forward friction should be more when pulling the topspin ball.

Downspin ball: 1. First of all, the lead shot: the downspin ball is relatively bottom, and it has a strong downward rotation, and we need to use a strong upward force to overcome his descending force. At this time, you need to bring the racket to the bottom, the center of gravity is lowered, and the racket is swung from the bottom and back to hit the ball, and the hitting time is the descending period.

2. The second is the plate type: the plate type should be slightly forward.

It can be judged by the method of exclusion and the method of flags.

1. Elimination method: that is, when the racket touches the ball, the paddle surface leans back and there is a downward or sideways action, which is downspin or side downspin; In addition, it is judged to be a "family" of topspin, because topspin, side topspin and non-spin catch are basically the same, and they can all be excluded from downspin. The greater the downward force and the more the racket face is tilted, the greater the downspin strength, and vice versa.

The action that is easy to be confused with the downspin ball is the serve non-spin ball, they are very similar in action, the difference between the action of the downspin and the non-spin ball, it depends on whether there is a downward friction and hitting part, there is a forward and downward action, but the hitting part is the center of the ball, such a serve is non-spin or slightly downspin.

2. Marking method: that is, the front and back sides of the racket are the markers for judgment. Take the right-handed spin and backspin as an example, the spin and backspin are mostly squat serves, and the right side of the opponent's front friction ball with the racket is the spin; The left side of the ball rubbed against the opponent's paddle is backspin; In short, "the positive is the good, the reverse is the negative".

Use the front of the racket to rub the ball from the left back to the right side of the ball to rub the ball downward, that is, to spin downward; Use the front of the racket to rub the ball from the left back to the right front of the ball to rotate the ball upward; Rubbing the ball from the right back to the left side of the ball with the reverse side of the racket is reverse downspin; Rubbing the ball from the back of the right to the left front of the ball from the back side of the racket is reverse topspin. Spin (down and up) and reverse spin (down and up) in the opposite direction of the left and right spin balls, and the opponent's paddle is on the right side of the ball to the left of the opponent; The opponent's paddle is on the left side of the ball and is connected to the opponent's right side. To judge the spin strength of the spin (down and up) and reverse spin (down and upspin), the main thing to look at is the amount of friction force at the moment of hitting the ball.

Use the same motion to deliver deceptive downspin and topspin.

The topspin ball accelerates forward after impact, while the downspin ball rebounds significantly

Under normal circumstances, if the opponent wants to send a downspin ball, when shooting, the angle of the racket must be flat, and the wrist must have a hook action, because only in this way can we ensure that the ball is better rubbed, and at the same time ensure that the arc can be low and flat.

Therefore, when sending downspin, it is generally the body that is pressed down, the board is flat, and the middle and lower part of the ball or the bottom are rubbed. It is important to note that the shot position is near the lower edge of the racket.

What needs to be watched out for is the feints of the other party.

On the one hand, if the shot is close to the top edge of the racket or the handle, it will not turn very well, even if it is served with a downspin technique.

On the other hand, if the ball is hit at the lower edge of the racket, but the opponent gives a small impact to the ball at the moment of exit, then the ball must be a non-spinning ball. If you still deal with the downspin ball at this time, you will be beaten by the opponent.

Thirdly, after the opponent has sent the downspin ball, he will use a very fast speed to stand up the plate and make the illusion of topspin to confuse you.

If the opponent serves the topspin ball, then the plate shape at the moment of service should be upright, standing up and pushing forward.

At the same time, pay attention to the other person's feints. After the topspin, then use a fast speed to flatten the plate and make a feint of the downspin, at this time, if you go to pick up the downspin in the same way, you will be directly started.

It looks like the arc of the ball.

Under normal circumstances, the topspin ball jumps faster after landing on the stage and goes forward; The downspin ball beats slowly after it lands on the table, and it doesn't go forward much, and some even go back.

Upspin** Rub the upper part of the ball so that its vertex position rotates forward.

Downspin** Rub the lower part of the ball so that its bottom position rotates forward.

Left-handed ** rubs the left side of the ball, and when viewed from top down, the ball rotates clockwise.

Right-handed ** rubs the right side of the ball, and when viewed from above, the ball rotates counterclockwise.

1. Put the table tennis racket vertically, after the table tennis ball contacts the racket, there is an upward movement trend is the upward rotation, there is a downward movement trend is the downward rotation, like the left movement is the left rotation, and the right movement is the right rotation;

2. Draw 2 vertically crossed circles on the table tennis ball, and carefully observe the direction of rotation of the ball: the top of the ball moves towards itself is the top spin, and the top moves in the opposite direction of the ball is the downspin.

Haha: Looks like a novice on the road.

You're talking about pure topspin and downspin; In fact, the topspin ball has a strong forward momentum just like your curve ball, if you can't prevent it, it will fly, and when the topspin ball lands, go forward for a certain distance, so the topspin ball should be counterclockwise;

The downspin ball is naturally in the opposite direction to the topspin ball, which is clockwise; The downspin ball you can try yourself is similar to a chipping or rubbing, and the ball doesn't go too far when it lands in opposite directions
