Body position: the left foot is slightly in front, the body leans slightly to the right, and the left palm holds the ball in front of the right body. Keep your eyes on the ball

Throw the ball and lead the racket: throw the ball up with your left hand, keep your eyes on the ball, and at the same time hold the wrist of the racket straight with your right hand, and hold the wrist horizontally for a little abduction.

Swing to catch the ball: the right arm swings from the right rear to the left front and down (see the next step for specific actions).

The racket touches the ball:

A: Hitting time: When the ball falls from the high point to slightly higher than or even higher than the height of the net, the forearm accelerates to exert force to the lower left, and at the same time, the wrist flexes and adducts when holding the backhand.

B: hitting position: the lower part of the ball rubs towards the bottom. Wipe the ball as thin as possible, because it falls from top to bottom. The racket with thin friction is almost parallel to the ground, so the racket is perpendicular to the ball, so there is no need to worry about the problem of insufficient positive pressure.

C: racket angle: backward (nearly horizontal).

D: the trajectory of the ball: after the ball is hit, the first landing point is close to the net. If you serve a long ball, the first landing point after serving is close to the end line of the table.

Homeward swing: after hitting the ball, the arm continues to swing to the left, forward and down, and then returns quickly.

Force parts: mainly forearms and wrists, which cooperate with the movement of the center of gravity all the time.

2. Preventive measures

The force is mainly exerted on the forearm, wrist and fingers. During the exercise, you should realize that the center of gravity of your body moves from your right foot to your left foot.

Experience the action of the racket cutting the ball more. Especially when shooting horizontally, you can imagine the feeling of cutting things down with a kitchen knife. The rotating quality of backspin service depends on whether the racket suddenly rubs the ball, whether the rubbing angle is appropriate, and how hard the forearm stretches from bending to forward and downward.

In training, we should strengthen the awareness of high-quality service and highlight the strong rotation characteristics of backspin service.
