Table tennis crossboard reverse rotation teaching, how to send table tennis counter rotation ball

Table tennis crossboard backspin** ball:

1. Use different parts of the racket to hit and rub the ball, and send out balls with different spins. If you hit and rub the ball with the underside of the paddle surface and the upper side of the paddle surface, you can send out the corresponding turn and non-turn ball;

2. Use the spiral to guide the racket, if you hit and rub the ball in different stages and directions, it will produce different spins. Touching the ball in the direction of the lower spiral will produce a lower spiral; Touching the ball in the direction of the upper spiral will produce an upper spiral;

3. Different ways of using the wrist to exert force, resulting in different rotations** If it is a spring force, it is not too rotating, if it is an upper spiral friction force, it is an upper spiral rotation;

4. Appropriately increase the thickness of the sponge and enhance the viscosity of the racket, which can enhance the rotation of the table tennis. This issue is even more important after the use of large balls;

5. Increase the time and distance of the resultant force acting on the racket: for example, when the ball is rotated side-spinning, the ball should be rubbed near the right side of the racket surface; For example, when the ball does not rotate sidespin: the ball should be rubbed near the left side of the paddle surface;

6. Increase the action appropriately, speed up the swing speed, and cut thin: in this way, under the condition that the swing speed direction is far away from the center of the ball, the faster the swing speed, the greater the hitting force, and the power of the racket to rub the ball will also increase, so the rotation of the ball will be strengthened.

When it comes to the power of the serve, especially the afterburner, people often think of the consequences of afterburner: either the ball flies out of bounds or the ball bounces too high. But in fact, the afterburner short ball, the ball is short, spinning, low, and has a good landing point; The afterburner long ball, the ball is long, urgent, turning, and falling on the left and right corners, which reflects the artistry and technique of table tennis.

It is not only possible in practice, but also in theory. As long as we control the proportion of impact force and friction force when afterburner, appropriately increase the length of the ball rubbing on the racket, reduce the friction thickness, and appropriately extend the time for the ball to rub on the racket, we can achieve the above effect.

How to reverse rotate the ball in table tennis: 1. Prepare the posture, separate the feet left and right, bend the knees slightly, and lean the center of gravity of the body slightly forward;

2. Lead the clapper to the right rear, sink the right shoulder, and shift the center of gravity to the right foot;

3. The clapping hand continues to lead the shot to the right rear, the center of gravity of the body gradually decreases, and the waist and shoulders should rotate with the center of gravity of the body;

4. After hitting the ball, swing the racket forward and upward with the forearm driven by the big arm, and the center of gravity of the body will gradually move to the left foot, and the forearm will be quickly contracted at the moment of rubbing the ball;

5. After the batting action is completed, the racket is swung to the forehead, and the center of gravity of the body is shifted to the left foot, and then quickly restored, ready to hit the next cricket.
