The serving technique of table tennis contained many elements and there were many types of serving. ** I. Common Key Points of Serves ** 1. ** Tossing the ball ** - The ball must be thrown steadily, including the height of the ball and the stability of the ball's rise and fall after throwing it. 2. ** Point of contact ** - The height should be appropriate. The contact point of the long ball should be lower, and the contact point of the short ball should be higher. 3. ** The ball is the first to jump on the table on our side ** - The first jump should be near the end line of the table when serving a long ball, and the middle position when serving a short ball. 4. ** Clapping ** - When holding the racket, the web between the thumb and forefinger should not be too tight to ensure the flexibility of the wrist and fingers. 5. ** Lead Auction ** - The lead, especially the wrist, had to be sufficient. 6. ** Power ** - Arm and wrist forward, downward force must pay attention to skill, to prevent the ball from falling into the net, bouncing too high or out of bounds. 7. ** Rubbing Ball ** - The part of the racket that rubbed the ball and the direction of the force must be accurate. Try to use similar movements to send out different spinning balls. 8. ** Body coordination ** - Focus on the strength of the forearms and wrists, and pay attention to the coordination of the waist to improve the quality of the serve. Take the right hand grip as an example. The center of gravity of the body moves from the right foot to the left foot when serving with the forehand, and the reverse is true when serving with the backhand. After each contact with the ball, the arm should be waved and quickly restored. ** 2. The preparation posture for the serve (Take the right hand as an example)** 1. ** Forehand serve ** - With his left foot slightly forward and his body slightly tilted to the right, he placed the ball in his left palm on the right side of his body. 2. ** Backhand serve ** - His right foot was slightly forward, his body slightly tilted to the left, and his left palm held the ball in front of his body to the left. ** 3. Main types of serve techniques ** 1. ** Forehand flat serve ** - [** Characteristic and Function **: Average speed, slight topspin. This is a basic serving method for beginners. It's easy to practice with a forehand attack or backhand push.] - ** Action essentials **: Throw the ball with your left hand and rotate your right arm inward at the same time. The racket face is slightly tilted forward to the right and back. When the ball drops from the high point to slightly higher than the net, the upper part of the ball will exert force to the left front. - ** Note **: Beginners are prone to not throwing the ball, hitting the ball inside the table, or breaking the rules. 2. ** Backhand flat serve ** - [** Character and Function **: The nature of the serve is similar to a normal serve with a forehand, but the technical movements are quite different. It is the foundation for mastering a high-quality backhand serve.] - ** Action essentials **: Throw the ball with your left hand and rotate your right arm outward at the same time. The racket face is slightly tilted forward to the left and back. When the ball drops from the high point to a little higher than the net, the upper part of the ball will exert force to the right front. - ** Note **: In addition to the common problems of a flat serve with a forearm, it is easy for beginners to cut forward and below to cause a rapid backspin. 3. ** Forehand serve with a right topspin shot (running ball)** - ** Special Effect **: Fast ball speed, long landing point, large angle, strong momentum, low flight arc and slanted to the left, strong topspin on the right, can form a stalemate with specific opponents in the middle and far distance or against opponents who are good at rubbing attacks. - ** Action essentials **: Throw the ball with your left hand and rotate your right arm inward at the same time. The racket face is slightly tilted forward. The forearm wrist naturally hangs down. The elbow joint is higher than the forearm and is pulled to the right. When the ball drops from the high point to the net height, the right side of the ball will rub to the right side. The moment the ball is touched, the thumb will press down and the wrist will shake from the right back to the left. - ** Note **: Up to two lines, slanted and straight. The angle should be as large as possible. Sometimes, it can be used to coordinate with the opponent's middle. 4. ** Backhand Quick Shot ** - [Special Effect: Contain the opponent in a match. Occasionally, you can use it to suppress the opponent's backhand and then change the forehand as a tactical cooperation.] - ** Action essentials **: Toss the ball with your left hand and rotate your right arm outward at the same time. The racket face is slightly tilted forward. The upper arm is naturally close to the left side of the body and leads the racket to the left back. When the ball drops from the high point to the middle upper part of the left side of the ball when it is lower than the net height, the forearm will accelerate and swing horizontally to the front right. The wrist will control the racket and apply force to rub the ball. The waist will rotate to the right. 5. ** Reverse spin serve ** - [** Special Effect **: Enrich the variations of the serve rotation and increase the difficulty of the opponent's judgment of the rotation. It is suitable for people who have the ability to attack with a backhand.] - ** Action essentials **: The height of the normal serve is close to the waist position, and the reverse rotation serve is at the chest position. By rubbing the racket at different positions, the topspin ball, the backspin ball, the side topspin ball, and the side backspin ball can be released. 6. ** Hook serve (topspin in the middle)** - ** Special Effect **: Strong rotation, the ball will float in an arc after landing on the stage. It is not easy for the player to parry. It can score directly or create a scoring opportunity. - ** Key points to serve **: Don't throw the ball too high. When hitting the ball, your wrist strength is greater than your forearm strength. Use your body to control the arc. The first point of the serve should be on the table and not too close to the net. When serving, the racket should be more upright. It should rub the lower side of the ball more. The racket head should be higher than the racket face. 7. ** Backhand Long Ball ** - ** Special Effect **: The ball is fast, the landing point is long, and the momentum is large. It is a big threat to the opponent when it is sent to the opponent's backhand baseline position. It can increase the opponent's area of the countertop when used with the short ball in the forehand position, thus creating scoring opportunities. - ** Key points of service **: The ball should not be thrown too high. Increase the speed of the swing at the moment of hitting the ball. The first point of impact should be as close to the end line of the table as possible. 8. ** Forehand short ball ** - ** Special Effect **: Smaller strokes, faster shots. When the ball falls on the opponent's table, the second jump will not come out, making it difficult for the opponent to pull, rush, or pull. It can restrain the opponent's speed. - ** Key points of serving **: Do not throw the ball too high. When hitting the ball, the strength of the wrist is greater than the strength of the forearm. The first point of the serve should be on the table and not too close to the net. The serve action should be similar to the long serve so that it is difficult for the opponent to judge. 9. ** Spinning and not spinning balls **: Using similar techniques to send out a ball with strong spin (usually a backspin ball) and basically no spin, making it difficult for the other party to judge. It is easy to make mistakes when receiving the serve, resulting in passive or even direct loss of points. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

There was no reaction between the carbon dioxide and the hydrogen dioxide. This was because carbon dioxide (CO2) was a non-metallic oxide-like compound, and hydrogen iodinate (Hi) was a non-metallic hy dride. Both of them were compounds, and what happened between the compounds was a metathesis reaction. This kind of reaction required at least one of the three products to be formed, such as precipitations, gas, or water, before the metathesis reaction could occur. If the two reacted, it would not produce any of these three. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
