Fitness precautions:
1. Reduce the tension (tightness) of badminton racquet line: In a certain range of high pounds, a looser racquet line can provide greater winding effect, which can make a faster and more powerful ball with less vibration.
2. Choose a racket shape with a large sweet area: the so-called sweet area is the best hitting area of the racket face. When the hitting point is in the sweet zone, it can give you enough hitting power, control the ball, and make you feel very comfortable. The sweet area of the racket is larger, and it is more difficult to hit the non-sweet area when hitting the ball, so there are fewer chances of vibration and less chances of injury.
3. Check the size of the handle of the racket: If the grip of the racket is too small, when the ball does not hit the sweet zone, the torque of the racket will be greater and the damage to the arm will be greater. If the grip is too big, the palm of your hand can't hold the racket and it is easy to get tired.
The appropriate size should be that there is a gap of about 5-8mm between the ring finger and the big fish muscle when holding the racket forehand.
4. Check the hardness of the racket: A racket with high hardness requires the player to make greater efforts when hitting the ball, thus making the arm more prone to fatigue and injury.
Using a less hard racket, players can hit a more powerful ball without too much force, which reduces the possibility of arm fatigue. The average hardness of badminton racket shaft is greatly reduced compared with previous years. Of course, the softer racquet shaft has less control over the direction of the ball.
5. Pay attention to whether the hitting posture is correct: incorrect hitting posture is an important cause of injury.
