Badminton is a national fitness sport. Badminton seems to be a simple way to learn. At that time, if you master the strength and posture and play badminton correctly, it will be easier to get started and lose weight faster. Now there are more and more badminton lovers. Playing badminton can help you lose weight. Of course, some precautions should also be understood. Pay attention to the following points when playing badminton: 1. Choose a racket with a bigger sweet area. The so-called sweet zone is the best hitting area on 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. 2. Check the size of the racket handle. If the grip of the racket is too small, when the ball doesn't 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. 3. Reduce the tension (tightness) of feather strings. Loose ball strings can provide a greater wire bed effect, and can play faster and more powerful balls with less vibration. 4. Pay attention to whether the hitting posture is correct. Incorrect hitting posture is an important cause of injury. Such as: the hitting point is too low, behind the ball, the side is not enough when hitting the ball, swinging the arm to hit the ball and so on. Consult the experts around you and correct your mistakes. 5. Check the hardness of the racket. A hard racket requires the player to make greater efforts when hitting the ball, which makes 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. At present, the average hardness of feather bats has been greatly reduced compared with previous years. Of course, the softer racquet shaft has less control over the direction of the ball.
