Men who often play table tennis can cure myopia

　　Table tennis is very popular in our country and is our country’s “national sport”. Many parents let their children play table tennis from elementary school for the purpose of exercise Body. But some parents may not know that the latest research shows that playing table tennis can cure myopia.

　　Can playing table tennis cure myopia?

　　1. When looking at things at close range for a long time, the lens is always in a highly adjusted state. At the same time, when looking at nearby objects, the two eyeballs converge toward the root of the nose, causing the extraocular muscles to compress the eyeballs, which over time leads to myopia.

　　When playing table tennis, your eyes aim at the ball and constantly adjust their movements up and down, which can improve the tension of the ciliary muscles, allowing them to relax and contract; the extraocular muscles can also be constantly active to promote blood circulation in the eyeball tissue and improve eye function. Eye Improve visual acuity, eliminate eye fatigue, thereby preventing myopia. Play table tennis every day. Playing table tennis for a period of time can alleviate myopia.

　　2. When playing table tennis, due to the rapid speed of the ball, the landing point of the ball may be near or far, left or right, or rotate or not. In order to make accurate judgments, information about the ball is mostly obtained through the eyes. The eyeballs are always in high-speed motion and provide rapid feedback contact with the brain.

　　This unique sport that regulates eyes and vision can effectively improve the function of the ciliary muscles of the eyes for primary and secondary school students who are overburdened with academic work and read at close range for a long time, and has a positive effect on protecting vision and preventing myopia.

　　Common tips for playing table tennis

　　1. Use the center of gravity to control the ball, that is, playing with the whole body, not just relying on the arms, but using the movements of the legs, waist and other body parts to concentrate on hitting the ball. The performance is the feeling of using the center of gravity of the body to pull the ball, hit the ball and send it out, and the feeling of using the center of gravity of the body to suppress the incoming ball and send it out.

　　When recoiling, the center of gravity must be used to control the ball. Only the forearm and wrist movements are used, and the center of gravity is not used to adjust the arc. The ball is often unable to be pressed or the return quality is not high.

　　2. Use the "greeting" technique to make the ball more explosive. To make the loop ball violent, you should try to use the active greeting technique. You must have this consciousness of "welcome", that is, the first body should meet the front, the second step should meet the front, and the third method should also meet the forward. The problem with generating forward basic force is to pull the ball forward. This force is accomplished by forward center of gravity exchange. (Right hand as an example) The lunge with a solid right and an imaginary left must be done completely, that is, the right foot is firmly planted, the toes of the right toes are parallel to the bottom line of the table, pointing east.

　　3. "Retract the forearm according to the incoming ball." Don't take the arm back, but try to sweep it forward. If it can't move forward on its own, it will come back on its own. You don't have to worry. If you take it back, it will be boring.

　　4. The backhand of amateur horizontal skateboard is not as good as imagined. The problem of amateur horizontal skateboard is indeed concentrated on the backhand and the middle. The backhand is the specialty of the horizontal board, but many amateurs have not developed it well, and it turns out to be a weakness, so that they cannot compete with the push and block of the straight board.

　　Also, I feel that many crossboard positions are too close to the table, which affects the transition between forehand and backhand. In fact, it is also due to the problem of standing far away and backhand. Therefore, practicing the backhand well is the key to playing the horizontal plank well, and elbow control is very important. He who has the backhand wins the world. When doing the horizontal backhand, you must dare to take the initiative and apply force first.

　　5. Do the lead-in for "hitting the ball in front of you". Hitting the ball in front of you means hitting the ball in front of the navel, the center of gravity of the body.

　　6. When practicing the basic skills of the ball, you must have a rhythm to the opponent's ball and return the ball at basically the same speed. Only in this way can both parties practice in a rhythm without getting tired, so as to improve the hand feel.

　　7. The center of gravity of the body must be low so that the ball can be played stably. When turning sideways in the backhand position, the body must be lower in order to hit the ball accurately. But be careful to use it flexibly. Don't lower your center of gravity too low when pulling forward from the center. Otherwise, the shot will be too low and the ball will not be able to press the arc, making it easy to go out of bounds.

　　8. You must relax when hitting the ball. When hitting the ball, your arms must be relaxed and it will feel like you are turning the ball with your waist. The ball should feel like a hit (fast break), not friction. Take the initiative to hit the ball, don't passively let the ball hit your paddle. The waist should be relaxed and not tense, otherwise it will look like you are playing with a straight back. In fact, in the entire playing process, only the moment of hitting the ball is tense.

　　9. Coordinated force is the basis - the legs, cross and hands must move in the same direction at the same time. 10. Forward force is the guide - the legs, waist and hands must first act forward on the ball, and then adjust in other directions.

　　10. The fulcrum of force is the key - the fulcrum of the moment when approaching tennis is at the wrist joint, the fulcrum when approaching billiards is at the elbow joint, and the fulcrum when away from billiards is the hip joint on the side of the clapping hand! (Reference website: Minfukang)
