1. Table tennis pays attention to playing with the body, and the hitting power is mainly determined by the force transmitted to the racket when kicking the ground and turning the body.
2. Extended introduction.
There are four basic parts of batting, namely preparation, pitching, hitting and restoring.
PreparationThis includes basic positioning, judgment of the incoming ball, and body adjustments (including movement) prior to the start of the stroke. Filming lead。There is a lead in any action, but the way and method are different, plus the important position and role of the lead in the whole hitting process, it is necessary to separate it from the hitting action to understand and improve.
The lead shot is the beginning of the batting action, and a high-quality shot is closely related to a high-quality lead shot. In other words, the lead is the premise of improving the quality of the shot, the basic feature of the table tennis hitting action is the swing of the upper limbs, the swing is first from the starting point of the lead racket, it should include the coordination of the upper arm and the forearm, the coordination of the upper limb and the body, the way and method of swing, the direction of swing, the size of speed and amplitude, as well as the handling of swing and paddle surface. The lead shot also determines whether all parts of the body can be effectively mobilized to participate in the shot, and the degree of coordination of the body can also be seen through the lead shot.
Hitting the ball。Hitting the ball is the heart of the game. It is the most complex and precise of all the links, and the stability, accuracy and threat of the shot are all reflected in this link.
In addition to the same specific requirements as the lead link, the adjustment of the shape of the racket, the timing and rhythm of the shot, the use of power and the mastery of strength, the correspondence between the lead and the shot, and the correspondence with the selection and decision of which technique to use, will become the focus, therefore, it is also a skill, skill, variability and integrity of the link, a true reflection of the skill level of a golfer.
Restore the stage。When the batting action is basically completed and the ball is off the board, the reduction action has begun. In other words, the swing after hitting the ball and the corresponding cushioning of the movement.
It should be emphasized that after the ball is shot, how to continue the subsequent movements, pay attention to moderate convergence. Especially in the case of exertion, only pay attention to the release of force and movement, and do not pay attention to the subsequent tightening, and the result is that the amplitude of the action is too large and the follow-up is missing. It should be reminded that looseness and tightness, contraction and relaxation will be reflected to varying degrees in all aspects of hitting the ball, which is the response of the body's movement rhythm and the orderly performance of all parts of the body participating in sports.
Otherwise, the movement loses its ease and rhythm and appears to be overly tense or relaxed.

Personal playing experience: 1. The length of the distance of the lead racket: when the distance is just right, the force used is the least but the hitting power is the largest.
2. The strength of the shot. 3. If you want to increase the power of hitting the ball, it is best to move your arms, not your wrists. 4. Choose the timing of the shot yourself, and when it is appropriate enough, you can borrow the force, which will make it appear that the hitting power is great and the effect is also very good.
The timing of the shot is inappropriate, laborious, and the effect of the shot is not good. For the time being, I can only think about so much, I hope it helps you!

Forearm, when playing ball, the forearm drives the body to swing the racket. The wrist just adds spin and adjusts the angle of the racket when hitting the ball.

Walking with the ball: You can't hold the ball with both hands, or hold the ball with one hand, walk or run more than two steps, and if you want to move with the ball, you must shoot the ball.
