Several Concepts about badminton

Finger strength: When the racket is in contact with the ball, the fingers are suddenly tightened to generate strength, so that the rackets face direction conversion or speed up the swing speed.

Application: this force is the most important part of the batching action. It is the key to adjusting the batching direction and the distance between the batching, and is also a shortcut to quickly improve skills.

1. Twisting Force: If the valve is closed, the four fingers rotate clockwise to rub the racket handle to make the face rotate.

Application: it is mainly used for rubbing, pushing, and other actions with little force before the Internet.

2. Bending Force: the thumb and forefoot tighten the shoot handle to the fulcrum, and the other three fingers tighten from loose to flexion.

Application: it is mainly used for actions that require force, such as high-distance ball, flat Ball, ball extraction, and ball killing.

3. Twisting Force: the force between the above two groups is larger than twisting and smaller than twisting. It is a combination of the above two actions.

Application: it is mostly used for hanging and splitting in the backend.

4. Inner and Outer spin of the arm: flat the palm of your hand, and let the upward movement of the back of your hand be the inner spin. Turning from the back of your hand to the Palm is the external spin.

Application: this action is mostly used for force actions such as high-distance ball, flat ball, kill ball, and draw ball. Its role is to adjust the hitting surface and increase the instant explosive force of hitting the ball.

5. the inner side of the wrist and the external side: the arm is flat, the palm is standing in the same way as the handshake, the palm is raised to the external side, and the downward side is pressed to the inner side.

Application: mostly used for backhand hitting.

6, wrist flexion, extension force: put the arm flat, hand back up, when the wrist downward pressure for anterior flexion, wrist up to stretch.

Application: In the backend, You can vigorously kill the ball, play the ball, pick the ball, and other actions.

7. Shoot: Put your arm up and straight up, and then sink your elbow to make the racket move forward and bottom.

Application: it is mostly used for hitting a ball when the hitting point is low. It is a passive hitting. Such as playing flat in the midfield, playing near tennis, playing in the backend, or playing in a false action.

Special attention should be paid to the use of this action, which is rarely used in active hitting, but because this action can generate a large amount of explosive power, many players have become accustomed to using it and make the active hitting deformation, this affects the development of technology and the weakening of attack capabilities.

8. Start-up: it is the most used action in the competition, and it is also the key to winning and losing. The action is to hold the clap side of the foot slightly front, the other foot to withdraw half of the foot (except in special circumstances), when preparing, the two feet cannot stand solid (that is, with full feet on the ground ), this is not conducive to the ground to start, but should slightly lift the heel, knees slightly bent, sinking shoulder waist, holding between the chest and abdomen, and make the feet to maintain micro motion. Pay attention to adjusting the center of gravity when starting. Generally, the center of gravity is opposite to the de-direction. If you want to go to the right-hand network, you should first move the center of gravity to the left foot, before going to the left hand network, and then move the center of gravity to the right foot, in order to generate explosive force and increase the startup speed.

Here are some explanations of wrist movements:
