1. Make a good arc.
Because of the net, table tennis must be shown in a certain arc form. How can we make a suitable and effective arc?
(1) Adjust the direction of the racket.
1) When the ball falls below the net after the rebound, the racket should push forward and increase the flying arc of the ball appropriately to avoid getting off the net. Such as: pull the loop ball and put the high ball.
2) When the incoming ball is higher than the net after bouncing, the racket should be forced forward and downward, and the flying arc of the ball should be appropriately reduced to avoid being out of bounds. Play a half-high ball and push the ball hard.
(2) Adjust the racket face angle.
1) in the same direction, if the racket face leans forward slightly, the flying arc height of the ball will decrease; On the other hand, if the racket face is tilted backward, the height of the ball's flying arc will increase.
2) Under the condition of the same hitting distance, if the racket head leans forward, the upward force should be increased while pushing forward, so that the flying arc of the ball can be appropriately increased to make the ball hit the predetermined landing point; On the other hand, when the racket leans back, the downward force should be increased while pushing forward, so that the flying arc of the ball can be properly lowered and the ball can hit the predetermined landing point.
(3) adjust the intensity.
1) In the same case, if the hitting power is high and the ball speed is fast, the flying arc of the return stroke will increase accordingly, and the hitting distance will also increase. On the contrary, if the force is small and the ball speed is slow, the arc of returning the ball will be reduced accordingly and the hitting distance will be shortened.
2) Under the same hitting distance, the greater the hitting power, the faster the ball speed and the lower the flying radian of the ball; On the contrary, the hitting force is small, the ball speed is slow, and the flying arc of the ball increases.
(4) the method of laying circular arc
There are several ways to create an arc by attacking the ball:
1) In the case that the incoming ball is close to the net and high after bouncing, the return arc is not high. In the attack, just hit the middle and upper part of the ball and push it forward and down.
2) When the net is far and high after the incoming ball bounces, pay attention to give the ball an appropriate arc to shorten the hitting distance. When attacking, hit the ball in the middle and upper part, with a little upward force and a little friction to ensure hitting the ball.
3) When the ball is far from the net and low after bouncing, when hitting the ball, in addition to hitting the middle of the ball or slightly above the middle, applying force forward and upward can increase some friction and hitting power to ensure hitting the ball.
4) When the incoming ball is near the net low, make the middle or slightly lower middle of the ball bear the force forward and upward, and add some friction actions to reduce the force and avoid the ball out of bounds.
5) When the incoming ball has a strong topspin, you should hit the middle and upper part of the ball, exert force forward or downward, and appropriately increase some hitting power to avoid the ball out of bounds.
6) When the incoming ball has a strong backspin, increase the rubbing force in the middle or slightly higher than the middle when hitting the ball, and exert force forward and upward to avoid the ball being caught.
There are several ways to form an arc by rubbing (cutting) the ball:
1) When the incoming ball bounces up close to the height of the net, wipe (cut) the middle part of the ball slightly and exert force forward and downward. Throw the ball on the opponent's table.
2) When the net of the incoming ball is high, when rubbing (cutting) the ball, press it forward hard in the middle and lower part of the ball to avoid causing the ball to go out of bounds.
3) When the net of the incoming ball is low, when rubbing (cutting) the ball, hit the middle and lower part of the ball and send the ball forward to avoid the ball being caught.
4) When the incoming ball bounces and is close to or low from the net, when rubbing (cutting) the ball, the middle and lower parts of the ball should be forced forward, not too hard, so as to avoid the ball being caught in the net or out of bounds.
5) When the incoming ball has a strong rotation, when wiping (cutting) the ball, hit the middle, lower or lower part of the ball, and hit the ball forward hard to avoid the net.
Increase speed
"Fast" is one of the important magic weapons to win table tennis. How can I make the ball run faster?
(1) Understand the principle of growth.
1) Time before hitting the ball: from the moment when the ball bounces off the table to the moment when the player's racket returns to hit the ball.
2) Time for the ball to fly in the air after hitting the ball: This time refers to the moment when the ball leaves the racket and the moment when the ball falls to the opponent's table.
Improving the hitting speed is to shorten the time required before hitting back and the time for the ball to fly in the air after hitting.
(2) Ways to improve the hitting speed
1) When hitting the ball, stand as close to the table as possible to shorten the time required for returning the ball.
2) When hitting the ball, increase the hitting power as much as possible, reduce the flying arc height as much as possible, and shorten the flying time of the ball in the air.
Strengthen rotation
Speed and rotation have become two important issues in the development of table tennis technology. Whoever can combine them well will be in a favorable position in the competition. How can I make a solid spinning ball?
(1) Understand the reason for rotation.
1) The greater the moment arm of the ball, the greater the friction and the stronger the rotation of the ball, and vice versa.
2) In the case of equal arms, the greater the hitting power, the stronger the rotation, and vice versa.
3) The better the viscosity of the racket, the greater the friction, so the stronger the rotation, and vice versa.
4) The greater the K of the racket, the greater the radius, the greater the linear velocity of the ball contact point and the stronger the rotation.
(2) the method of strengthening rotation
1) When hitting the ball, increase the torque acting on the ball as much as possible.
2) Hit the ball with a racket with a large linear speed. Hit the ball with the top of the racket, which is beneficial to strengthen the rotation of the ball.
3) Improve the performance of the racket and increase the friction coefficient of the rubber.
Increase strength
The hitting power is the basis of improving the speed and rotation of the ball. How can we increase the impact?
(1) Understand the principle of increasing the hitting force.
1) When the speed increases first, the longer the acceleration distance, the faster the instantaneous speed that the racket can reach and the greater the strength, and vice versa.
2) Speed up the swing, because in the case of the same acceleration distance, if you speed up the swing, the hitting power will be great, and vice versa.
3) Keep the hitting point as far away from the body as possible and make the hitting radius longer. When the speed is constant, the larger the radius, the faster the speed and the greater the strength, and vice versa.
(2) the method of increasing hitting power
1) Before hitting the ball, the hitting point should be properly away from the body to ensure that there is a proper distance to accelerate the swing.
2) Before hitting the ball, if the muscles are relaxed, it is convenient for the elongated muscles to contract quickly when hitting the ball.
3) When hitting the ball, make the swing speed reach the fastest and make the power fully act on the ball.
4) Improve the speed and strength of the arms and the whole body.
Control the landing site
The placement of table tennis is the main content of tactical changes. To improve the ability of landing point control and landing point change, it is necessary to highlight landing point practice in the basic technical practice content. Over time, the impact point of the ball can be effectively controlled, which means that the impact point can be changed according to tactics.
