What are the basic skills of table tennis? How can I serve?

Give you a comprehensive explanation of serving skills.

First, the forehand flat serve 1. Characteristics, performance and function The flat serve is a kind of service with general topspin and general speed. It is the most basic service method for beginners and the basis for mastering other services. A flat serve won't make the ball spin strongly, and it's easy for the opponent to catch it back. After receiving the ball, forehand attack or backhand push is easy to form a round-trip ball, which allows beginners to quickly form a correct "dynamic stereotype" of attack and backhand push. 2。 Action essentials (take the right-handed racket as an example, the same below) (1) Before hitting the ball, stand close to the table, including chest, abdomen and knees, and shift the center of gravity to the forefoot. Throw the ball up with your left hand, and turn your right arm inward, so that the face angle of the racket leans forward slightly and leads the racket to the right rear of your body. When the ball is thrown to a high point and begins to fall, the right arm swings from the right back to the right front. (2) When hitting the ball, when the ball falls from the high point to the top of the net, the upper part of the ball hits the left front. The first landing point of the ball after being hit is in the center of the table. (3) After hitting the ball, the arm continues to swing forward to the left, and quickly returns to the posture of preparing for continuous stalemate. 3。 Note that the forearm drives the wrist, and the center of gravity shifts from the right foot to the left foot during the action. * Beginners are prone to hit the ball together without pitching, and the ball hits the table or fouls. * From the very beginning, I tried to make my technical movements standardized and legal, so as to lay a good foundation for studying and practicing difficult serve in the future.

Second, backhand flat serve backhand flat serve and forehand flat serve are completely different in technical actions, such as standing position, racket, wrist rotation friction, reduction action and so on. The main purpose of beginners' learning backhand flat serve is to lay a foundation for mastering high-quality backhand serve in the future. 2。 Action essentials (1) Stand in the left corner of the table with your right foot slightly forward or flat, turn your body slightly to the left, and throw the ball with the palm of your left hand in front of the left. At the same time, the right arm rotates outward, so that the angle of the racket leans forward slightly and leads the racket to the left rear of the body. (2) When hitting the ball, when the ball falls from the high point to slightly higher than the net, the right arm swings from the back of the body to the front right, and the middle and upper parts of the ball force forward, and the first landing point after hitting the ball is in the center of the table. (3) After hitting the ball, the arm and wrist continue to swing to the front right and return quickly. 3。 Note * The main parts of the force are the forearm and wrist, and the body center of gravity moves from the left foot to the right foot during the action. * Beginners are prone to not throwing the ball, hitting the ball on the table, or cutting the ball back and forth with a racket to make the ball spin sharply, which is not conducive to basic training. * Starting from the beginner's backhand flat serve, we should focus on the coordination of upper and lower limbs, waist and hip joint. Technical actions are required to be standardized and conform to the rules. For example, it is more important to practice backhand or backhand attack and learn to practice backhand serve.

Forehand serve, backspin and spin 1. Characteristics, performance and function At present, this kind of service is the most used in table tennis at home and abroad. Many high-level players confuse their opponents with very similar techniques, sending out strong backspin and no ball with great rotation contrast, causing opponents to make mistakes in judgment and score directly or creating opportunities for three-board attack. The characteristics of backspin and spin ball are: slow ball speed, large choice of service landing zone and great change of rotation contrast. When the goal before backspin and non-rotating ball are used together, it is difficult for the opponent to take back the ball because of the similar service skills, resulting in net arrest, out of bounds or high ball. 2。 Action essentials (1) Before hitting the ball, the right hand spins forward to hit the ball. Action method: the left foot leans forward slightly and the body leans forward slightly. The ball is held in the palm of the left hand in front of the right hand, and the left hand throws the ball up and swings back and forth at the same time. (2) When hitting the ball, when the ball falls from a high point to a height slightly higher than or even higher than the height of the net, the forearm accelerates from flexion to extension and exerts force to the left front and lower part, at the same time, the grip wrist is straightened and retracted at the same time, the middle and lower part of the ball rubs to the bottom, and the first landing point after hitting the ball is close to the net. If you serve a long ball, the first landing point after serving is close to the end line of the table. (3) After hitting the ball, the arm continues to swing to the lower left and returns quickly. 3。 Precautions * Forearms, wrists and fingers are the main parts of force. During exercise, the center of gravity of the body moves from the right foot to the left foot. * How the spin quality of the backspin service depends on whether the sudden friction of the racket on the ball is concentrated, whether the friction angle is appropriate, and the degree of force exerted by the forearm from bending to forward and downward extension. * Strengthen quality awareness in training, and pay attention to the strong spin characteristics of backspin service.

Forehand serve can't turn the ball. Features, performance and function Forehand serve without turning is often used in conjunction with forehand serve with backspin to achieve better results. Forehand serving without turning around is almost the same in appearance as backspin and spin serving, which is easy for opponents to make mistakes in judgment and directly lose points or have opportunities, resulting in indirect serving. 2。 Action essentials (1) Before hitting the ball, the standing position, preparation posture, throwing, leading and swinging movements should be completely consistent with the forehand. (2) The difference between the non-turn serve and the forward serve is that the arm is slightly rotated, the backswing angle is reduced, the downward friction is reduced in the middle and lower part of the ball, and the action point is close to the center of the ball, forming a non-turn serve. (3) After hitting the ball, the racket face after hitting the ball should be adjusted as soon as possible, which is similar to the action of serving the backspin and spinning the ball to confuse the opponent. 3。 Note * In the match, the use of this service should be flexibly adjusted according to the opponent's playing style and technical characteristics. * The fake action of not being able to spin the ball is more realistic. Try to confuse the fake with the real, which is a threat.

Seven, backhand serve backspin and spin ball 1. Features, performance and function When backhand serve has spin ball and spin ball, it is often used in combination with backhand serve without spin ball. This kind of service is often used by players who hit straight and horizontal. The ingenious combination of straight ball, oblique ball, long ball and short ball at the landing point is beneficial to the attack on both sides of the three boards. 1。 Action essentials (1) Before hitting the ball, stand back or sideways with your right foot, lean slightly to the left, and hold the ball in front of your body with your left palm. The left hand throws the ball up and the right arm rotates inward when the racquet is taken. The curve of the wrist grip is straight, and the wrist grip is extended horizontally, so that the racket face leans back and the racket is led to the left rear of the body. When you catch the ball, your right arm swings back from the upper left to the upper right. (2) When the ball falls from a high point to a height slightly higher than or even higher than the height of the net, the forearm exerts force to the left front and lower part, and at the same time, the wrist is stretched out while the wrist is held horizontally, and the middle and lower parts of the ball are rubbed to the end. The first landing point of the ball after being hit is close to the net. (3) After hitting the ball, the arm continues to swing right, forward and down, and returns quickly. 3。 Note * The wrist and forearm are the main parts of the force, and the body center of gravity moves from the left foot to the right foot during the action. * Backhand serve is limited by the body, so it is necessary to give full play to the coordinated force of abdomen and waist rotation. * At the moment when the racket touches the ball, increasing the strength of wrist and finger is the key to improve the service quality.

Eight, backhand can not turn the ball 1. Characteristics, performance and function In the competition, backhand serve and backspin serve are mostly used together. In backhand serve, almost like backhand serve plus spin, it is easy for opponents to lose points directly or create opportunities for the third board. 2. Action essentials The main difference between backhand non-turnover serve and backhand down-turnover serve is that the arm pronation amplitude is small, and the backswing angle of the racket face is reduced. By hitting the middle and lower part of the ball, the downward friction is reduced, and the ball is pushed forward slightly to make the force close to the center of the ball, thus forming a non-turnover ball. 3. Precautions * Most forehand short balls do not turn, and most backhand long balls turn. * On the landing point of long and short balls, try to be as short as possible, avoid serving balls that are not too short and not too long, and the rotation contrast is small.

Nine, forehand serve left topspin +0. Characteristics, performance and function Forehand serves with the left side spinning up (down), which is the most commonly used service method for athletes in the competition. This kind of service mainly changes in rotation, the flying arc turns to the opponent's left, and the opponent's return ball bounces up (down) to his left. Serving two different spinning balls with approximate technique will confuse each other. 2。 Action essentials (1) Stand on the left side of the table before hitting the ball. Hold the ball in the palm of your left hand in front of your body. When the racquet is taken, the left hand throws the ball upward, while the right arm rotates outward, the wrist of the racquet is straight, and the wrist of the horizontal racquet is abduction, so that the racquet face direction is slightly left, the racquet is slightly upward to the right, and the waist is slightly rotated to the right. When you catch the ball, your right arm swings from the top right and sits down. (2) When hitting the ball, when the ball falls from the high point to the height close to the net, the forearm accelerates the swing, the grip wrist is straight, the horizontal grip wrist is retracted, and the waist cooperates with the left pass. When the middle of the ball is rubbed to the upper left, it is a left topspin, and when the middle of the ball is rubbed to the lower left, it is a left topspin. Adjust the distance of the first landing point of the ball according to the length of the service. (3) After hitting the ball, the arm continues to swing to the left and returns quickly. 3。 Note * The left backspin serve method is basically the same as the left topspin serve method, with the difference that the racquet is backward and upward, the arm swings left and downward, and the middle and lower parts of the ball wipe the ball to the left and downward, and the height of touching the ball is slightly higher than the net. * When holding the upper left (lower) ball horizontally, it is best to loosen the three fingers of the grip to increase the flexibility of the wrist. * In the competition, forehand left topspin and forehand left backspin can be used together, so that the side topspin and backspin with great rotational contrast can be served in a similar way, creating opportunities for the three boards. * If the opponent's chopping or catching skills are conservative, you can use topspin to open the way and strive for the initiative. * The service positions are mainly forearms and wrists, with waist assistance. During exercise, the center of gravity of the body moves from the right foot to the left foot.

Serve the top right (bottom) spin with Tenuto backhand 1. Characteristics, performance and function The backhand right-hand spin serve mainly changes in rotation, the flying arc turns to the left, and the opponent's return ball bounces to the right. Because the approximate technique is used to serve two different spinning balls, it can play a role in confusing opponents. 2。 Action essentials (1) Before hitting the ball, stand on the left half of the table, with your right foot slightly forward or flat, your body slightly leaning to the left, and your left palm holding the ball in front of your body. When leading the racket, the left hand throws the ball upward, and the right side rotates slightly inward, making the racket face almost vertical, leading the racket to the left rear, and the waist rotates slightly to the left. When you catch the ball, your right arm swings from the left back to the upper right. (2) When hitting the ball, when the ball falls from the high point to the height close to the net, the forearm accelerates to swing to the upper right. The straight wrist is extended, the horizontal wrist is contracted, and the waist is rotated to the right. Friction to the upper right in the middle of hitting the ball will make a right topspin, and friction to the right in the middle of hitting the ball will make a right backspin. Adjust the distance of the first landing point of the ball according to the landing point of the service. (3) After hitting the ball, the arm continues to swing to the upper right and returns quickly. 3。 Note * The right backspin serve method is almost the same as the right topspin serve method, but the difference is that the racket swings to the left, the right arm swings to the right and the middle and lower part of the ball rubs to the right, and the touch height is slightly higher than the net. * Horizontal backhand topspin should increase the swing range of the upper arm to the right.

Eleven, backhand sharp backspin 1. Characteristics, performance and function The backhand sharp backspin is characterized by fast speed and backspin, and the opponent's push-back and pull-back are easy to cause the net to break, while the opportunity ball is easy to appear when rubbing the ball back. After the ball is sent out, the flight arc is low and long. 2。 Action essentials (1) Before hitting the ball, stand on the left side of the table, with your feet almost flat, your body facing the table, and your left hand holding the ball in front. When the racquet is taken, the left hand throws the ball upward, and at the same time, the right arm slightly rotates to make the racquet face slightly backward and lead the racquet to the front upper abdomen. When you catch the ball, your right arm swings forward and upward from the back of your body. (2) When hitting the ball, when the ball falls from the high point to slightly lower than the height of the net, the forearm accelerates to push forward and cut down, and at the same time, the wrist slightly abducts and hits the middle and lower part of the ball. (3) After hitting the ball, the first landing point after hitting the ball is close to the end line. The arm swings back and forth with the trend, and then returns quickly. 3。 Note * This service can only be used for matching and containment. * The force is mainly exerted on the forearm and wrist, and the center of gravity is on the foot during the action. 12. Forehand high throw serve (1) Forehand high throw left topspin 1. Characteristics, performance and function: High throw serve is a legal combination serve. In addition to the low throw service, the high throw service increases the gravity of the ball falling vertically because it is thrown 2-3 meters high when falling. At the same time, when the racket force is used to wipe the ball from right to left, a left and right lateral force will be generated. "Two forces in one" increases the speed and rotation of the ball. 2。 Action essentials (1) When serving, stand on the left side of the table and hold the ball in the palm of your left hand in front of your body. When leading the racket, the left hand throws the ball vertically upward and the right arm rotates outward at the same time. The wrist of the direct grip is abduction, and the wrist of the horizontal grip is abduction, so that the spherical direction is slightly left, the lead is slightly right, and the waist is slightly right. When you catch the ball, your right arm swings from upper right to lower left. (2) When hitting the ball, when the ball falls from the high point to the height of the net, the forearm swings to the upper left, the waist rotates to the lower left, the wrist of the forearm controls the racket, and the middle of hitting the ball rubs to the upper left. (3) After hitting the ball, the arm continues to swing to the lower left and returns quickly. 3。 Note * Adjust the distance of the first landing point of the ball according to the length of the service. * Forearms, wrists and fingers are the main parts, and the waist is the auxiliary part. * After throwing the ball, because the falling speed of the ball is gradually accelerated, it is difficult for scholars to grasp the accurate hitting time and it is easy to miss. This situation can be avoided with practice.

(2) Forehand high throw left-handed ball 1. Characteristics, performance and function In the competition, the forehand high-throw left topspin can be used in combination with the forehand high-throw left topspin, and the side topspin with large rotation contrast can be issued by similar technology, creating opportunities for the three-board attack. 2。 Action essentials The action method of forehand high throwing left topspin is basically the same as that of forehand high throwing left topspin, the difference is that the racquet is pulled back and up, the arm swings down to the left, and the middle and lower parts of the ball are wiped down to the left. 3。 Note * If you hold the racket handle horizontally, it is best to relax the three fingers to increase the flexibility of your wrist. * When rubbing the ball hard, increasing the friction on the bottom of the ball is the key to improve the quality of rotation.

Thirteen, forehand squat serve (1) forehand squat serve right topspin 1. Under the characteristics, performance and function, the squat serve mainly changes in rotation, which is mostly used by horizontal hitters. Because the position and direction of the friction ball are different from that of the underhand serve, when the rotating ball lands on the opponent's table, the rebound direction is also different from that of the ordinary underhand serve. Squat serve is rarely used in today's table tennis match, and because of this, it often makes opponents feel strange, sudden and uncomfortable when used occasionally in the game. If you use squat serve according to your opponent's style of play and technical characteristics, it will sometimes have unexpected effects at critical moments. 2。 Action essentials (1) Before hitting the ball, stand with your left foot slightly forward or your feet parallel, lean to the right, and hold the ball with your left palm in front of the right. The left hand throws the ball up and squats at the same time. The right arm is raised above the shoulder, the wrist is abduction, and the racket face direction is slightly left. When you touch the ball, your right arm swings from left to right. (2) When hitting the ball, when the ball falls from the high point to the height of the net or slightly higher than the net, the forearm accelerates to swing from left to right, and at the same time, the wrist adducts and rubs the upper right side. (3) After hitting the ball, the arm and wrist continue to swing forward and upward, and quickly recover to prepare for the next shot. 3。 Precautions: Forearm and wrist are the main force parts, and the body center of gravity is between the feet when moving.

(2) Forehand squat serve 1. Characteristics, performance and function in the competition, forehand squat serves the right down spin and forehand squat serves the right up spin. In the same way, sending up and down spin balls with great rotation contrast confuses opponents and creates conditions for the three-board attack. 2。 The action essentials range from the preparation posture before throwing the ball to the recovery posture after hitting the ball. The action method of squat forehand serving right backspin is basically the same as that of squat forehand serving right topspin. The difference is that when the ball falls from the high point above the net, the racket is higher than the ball, hits the middle and upper part of the ball and rubs to the lower right, and the forearm swings from left to right. 3。 Precautions (1) When practicing squat serve, you are prone to foul actions such as hitting the ball in the rising period and throwing the ball to the back side with too large deviation angle. (2) In order to improve the strength of the squat serve, the racket face and technique are suddenly changed at the moment when the racket touches the ball. Both forehand and backhand serve balls with different spins and landing points. (2) backhand squat serve left topspin 1. Characteristics, performance and function In the competition, the squat backhand left topspin can be used in conjunction with the squat backhand left topspin. It is more effective to use this service for athletes who receive the service conservatively and mainly rub the ball. 2。 Action essentials The action method of squat backhand left topspin is basically the same as that of squat backhand left topspin. The difference is that the middle of hitting the ball rubs to the upper left, and the forearm and wrist swing from right to left. 3。 Precautions * Squat serve backhand left topspin, the opponent's return speed is faster, and the angle may be larger. Therefore, it is required to return to the ground quickly to take over cricket. * This serve technique fully exposes the angle of the racket, and it is not difficult for the opponent to judge the rotation. From the point of view of tactics and play, it can be used as a supporting service or as an unconventional sudden use at a critical moment. Fourteen, backhand squat serve (1) backhand squat serve left-handed ball 1. Characteristics, performance and function In the competition, the squat backhand serve can be used in conjunction with the squat forehand serve. The preparation posture, hitting and throwing actions of the two serves are exactly the same before hitting the ball, but when hitting the ball, the ball with different rotation, speed and landing point can be served by suddenly changing the hitting angle and the direction of force. The backhand squat service falls behind the opponent's table, and the rebound arc turns to the left, which is conducive to limiting the opponent's sideways attack. 2。 Action essentials (1) Before hitting the ball, open your feet in parallel and face the table. When shooting, the left hand throws the ball and squats at the same time, and the upper arm slaps the wrist to the lower right. When you touch the ball, your right arm swings from the lower right to the upper left. (2) When the ball falls from a high point to be parallel to or slightly higher than the net, the forearm accelerates to swing from the upper right direction to the lower left, and at the same time, the wrist is abduction, and the middle of the ball rubs to the lower left. The first landing point after hitting the ball should be reasonably adjusted according to the length of the serve. (3) After hitting the ball, the arm will continue to swing forward to the left, and quickly prepare for the next board to hit the ball. 3。 Note (1) In the choice of landing point, it is appropriate to serve the opponent's forehand short ball and backhand long ball. (2) It is difficult to control the landing point of squat serve short ball.

Second, backhand flat serve backhand flat serve and forehand flat serve are completely different in technical actions, such as standing position, racket, wrist rotation friction, reduction action and so on. The main purpose of beginners' learning backhand flat serve should be to lay the foundation for mastering high-quality backhand serve in the future. 2。 Action essentials (1) Stand in the left corner of the table with your right foot slightly forward or flat, turn your body slightly to the left, and throw the ball with the palm of your left hand in front of the left. At the same time, the right arm rotates outward, so that the angle of the racket leans forward slightly and leads the racket to the left rear of the body. (2) When hitting the ball, when the ball falls from the high point to slightly higher than the net, the right arm swings from the back of the body to the front right, and the middle and upper parts of the ball force forward, and the first landing point after hitting the ball is in the center of the table. (3) After hitting the ball, the arm and wrist continue to swing to the front right and return quickly. 3。 Note * The main parts of the force are the forearm and wrist, and the body center of gravity moves from the left foot to the right foot during the action. * Beginners are prone to not throwing the ball, hitting the ball on the table, or cutting the ball back and forth with a racket to make the ball spin sharply, which is not conducive to basic training. * Starting from the beginner's backhand flat serve, we should focus on the coordination of upper and lower limbs, waist and hip joint. Technical actions are required to be standardized and conform to the rules. For example, practicing backhand or backhand attack, practicing backhand serve is more important.

3. Forehand ball 1. Characteristics, performance and function The second type of service is characterized by fast ball speed, long landing point, strong impulse, large angle and strong suddenness. The flying arc of the ball is low and inclined to the left, and the right hand topspin is very strong. Sometimes, according to tactical needs, it is very effective to use this service when purposefully forming a stalemate with the opponent. For beginners of table tennis, it will be more advantageous to try this service, because the pace is slow and the scope of care for both sides is limited. It is also very effective to run the ball against athletes who are good at rubbing and attacking. 2。 Action essentials (1) Before hitting the ball, the left foot is slightly forward and the body is slightly deflected to the right. The left palm holds the ball on the front and right side of the body, and the left hand throws the ball up. At the same time, the right arm rotates inward, so that the racket face angle is slightly forward, the forearm wrist naturally droops, the elbow joint is higher than the forearm, and the racket is led to the right rear of the body. (2) When hitting the ball, when the ball falls from the high point to the net height, the right side of hitting the ball rubs to the upper right, and the thumb presses the racket at the moment of touching the ball, and the wrist swings from the rear right to the upper left. After hitting the ball, the first landing point of the ball is close to the finish line. (3) After hitting the ball, the arm continues to swing forward to the left and returns quickly. 3。 Note * The force is mainly applied to the forearm and wrist, and the body's center of gravity shifts from the right foot to the left foot during exercise. * When choosing a position, you can serve a long ball with a diagonal line and a large angle, or you can stand in the middle of the table and serve a double-line long ball to the opponent's forehand position or backhand position. The angle between the two lines is required to be as large as possible. After the ball falls on the opponent's table, it is required to be introduced from the sideline angle. Fourth, backhand 1. Characteristics, performance and function Backhand running is mostly used for training. Especially in basic training, serving a run ball with a sharp topspin on the backhand and standing near the table is beneficial to hitting the ball back and forth. Sometimes, according to tactical needs, in order to contain the opponent and cooperate with the main tactical play, a backhand emergency ball is occasionally used to purposefully hold down the opponent's backhand and then change the forehand. Backhand running is characterized by fast ball speed, long landing point, great momentum, flying arc deviating to the opponent's left and strong left topspin. 2。 Action essentials (1) Before hitting the ball, your right foot leans forward slightly or flat, and your body leans slightly to the left. Hold the ball in the palm of your left hand to the left of your body, throw the ball up with your left hand, and rotate your right arm outward, so that the racket face leans forward slightly. The upper arm is naturally close to the left, and the racket is led to the left rear of the body. (2) When hitting the ball, the right arm takes the elbow joint as the axis, the forearm swings to the left and the waist rotates from left to right. When the ball falls below the net height from the high point, hit the top left. At the moment of touching the ball, the forearm accelerates to swing to the right front, the wrist controls the racket to rub the ball, and the waist rotates to the right. (3) After hitting the ball, the first landing point of the ball is close to the end line of the table. After hitting the ball, the arm continues to swing to the right, and returns quickly. 3。 Note * The force is mainly exerted by the rotation friction between the forearm and the wrist, and the body center of gravity moves from the left foot to the right foot during the action. * The biggest difference between backhand running and backhand flat serving is that backhand running is fast, with topspin, the rebound arc of the ball is low after landing, and the flight arc is slightly biased.

5. Spin and spin the ball under the forehand 1. Characteristics, performance and function At present, this kind of service is the most used in table tennis at home and abroad. Many high-level players confuse their opponents with very similar techniques, sending out strong backspin and no ball with great rotation contrast, causing opponents to make mistakes in judgment and score directly or creating opportunities for three-board attack. The characteristics of backspin and spin ball are: slow ball speed, large choice of service landing zone and great change of rotation contrast. When the goal before backspin and non-rotating ball are used together, it is difficult for the opponent to take back the ball because of the similar service skills, resulting in net arrest, out of bounds or high ball. 2。 Action essentials (1) Before hitting the ball, the right hand spins forward to hit the ball. Action method: the left foot leans forward slightly and the body leans forward slightly. The ball is held in the palm of the left hand in front of the right hand, and the left hand throws the ball up and swings back and forth at the same time. (2) When hitting the ball, when the ball falls from the high point to slightly higher than or even higher than the height of the net, the forearm accelerates from flexion to extension to exert force to the left front and lower part, and at the same time, the racket wrist is straightened and retracted, and the middle and lower parts of the ball are wiped to the bottom, and the first landing point after hitting the ball is close to the net. If you serve a long ball, the first landing point after serving is close to the end line of the table. (3) After hitting the ball, the arm continues to swing to the lower left and returns quickly. 3。 Precautions * Forearms, wrists and fingers are the main parts of force. During exercise, the center of gravity of the body moves from the right foot to the left foot. * How the spin quality of the backspin service depends on whether the sudden friction of the racket on the ball is concentrated, whether the friction angle is appropriate, and the degree of force exerted by the forearm from bending to forward and downward extension. * Strengthen quality awareness in training, and pay attention to the strong spin characteristics of backspin service.

Forehand serve can't turn the ball. Features, performance and function Forehand serve without turning is often used in conjunction with forehand serve with backspin to achieve better results. Forehand serving without turning around is almost the same in appearance as backspin and spin serving, which is easy for opponents to make mistakes in judgment and directly lose points or have opportunities, resulting in indirect serving. 2。 Action essentials (1) Before hitting the ball, the standing position, preparation posture, throwing, leading and swinging movements should be completely consistent with the forehand. (2) The difference between the non-turn serve and the forward serve is that the arm is slightly rotated, the backswing angle is reduced, the downward friction is reduced in the middle and lower part of the ball, and the action point is close to the center of the ball, forming a non-turn serve. (3) After hitting the ball, the racket face after hitting the ball should be adjusted as soon as possible, which is similar to the action of serving the backspin and spinning the ball to confuse the opponent. 3。 Note * In the match, the use of this service should be flexibly adjusted according to the opponent's playing style and technical characteristics. * The fake action of not being able to spin the ball is more realistic. Try to confuse the fake with the real, which is a threat.

Backhand serve, backspin and spin 1. Features, performance and function When backhand serve has spin ball and spin ball, it is often used in combination with backhand serve without spin ball. This kind of service is often used by players who hit straight and horizontal. The ingenious combination of straight ball, oblique ball, long ball and short ball at the landing point is beneficial to the attack on both sides of the three boards. 1。 Action essentials (1) Before hitting the ball, stand back or sideways with your right foot, lean slightly to the left, and hold the ball in front of your body with your left palm. The left hand throws the ball up and the right arm rotates inward when the racquet is taken. The curve of the wrist grip is straight, and the wrist grip is extended horizontally, so that the racket face leans back and the racket is led to the left rear of the body. When you catch the ball, your right arm swings back from the upper left to the upper right. (2) When the ball falls from a high point to a height slightly higher than or even higher than the height of the net, the forearm exerts force to the left front and lower part, and at the same time, the wrist is stretched out while the wrist is held horizontally, and the middle and lower parts of the ball are rubbed to the end. The first landing point of the ball after being hit is close to the net. (3) After hitting the ball, the arm continues to swing right, forward and down, and returns quickly. 3。 Note * The wrist and forearm are the main parts of the force, and the body center of gravity moves from the left foot to the right foot during the action. * Backhand serve is limited by the body, so it is necessary to give full play to the coordinated force of abdomen and waist rotation. * At the moment when the racket touches the ball, increasing the strength of wrist and finger is the key to improve the service quality.

The backhand serve does not turn the ball 1. Characteristics, performance and function In the competition, backhand serve and backspin serve are mostly used together. In backhand serve, almost like backhand serve plus spin, it is easy for opponents to lose points directly or create opportunities for the third board.

Nine, forehand serve left topspin +0. Characteristics, performance and function Forehand serves with the left side spinning up (down), which is the most commonly used service method for athletes in the competition. This kind of service mainly changes in rotation, the flying arc turns to the opponent's left, and the opponent's return ball bounces up (down) to his left. Serving two different spinning balls with approximate technique will confuse each other. 2。 Action essentials (1) Stand on the left side of the table before hitting the ball. Hold the ball in the palm of your left hand in front of your body. When the racquet is taken, the left hand throws the ball upward, while the right arm rotates outward, the wrist of the racquet is straight, and the wrist of the horizontal racquet is abduction, so that the racquet face direction is slightly left, the racquet is slightly upward to the right, and the waist is slightly rotated to the right. When you catch the ball, your right arm swings from the top right and sits down. (2) When hitting the ball, when the ball falls from the high point to the height close to the net, the forearm accelerates the swing, the grip wrist is straight, the horizontal grip wrist is retracted, and the waist cooperates with the left pass. When the middle of the ball is rubbed to the upper left, it is a left topspin, and when the middle of the ball is rubbed to the lower left, it is a left topspin. Adjust the distance of the first landing point of the ball according to the length of the service. (3) After hitting the ball, the arm continues to swing to the left and returns quickly. 3。 Note * The left backspin serve method is basically the same as the left topspin serve method, with the difference that the racquet is backward and upward, the arm swings left and downward, and the middle and lower parts of the ball wipe the ball to the left and downward, and the height of touching the ball is slightly higher than the net. * When holding the upper left (lower) ball horizontally, it is best to loosen the three fingers of the grip to increase the flexibility of the wrist. * The forehand left topspin and forehand left backspin can be used together in the game, and the side topspin and backspin with large rotation contrast can be served in a similar way, creating opportunities for the third board. * If the opponent's chopping or catching skills are conservative, you can use topspin to open the way and strive for the initiative. * The service positions are mainly forearms and wrists, with waist assistance. During exercise, the center of gravity of the body moves from the right foot to the left foot.

Forehand high throw serve (1) Forehand high throw left topspin 1. Characteristics, performance and function: High throw serve is a legal combination serve. In addition to the low throw service, the high throw service increases the gravity of the ball falling vertically because it is thrown 2-3 meters high when falling. At the same time, when the racket force is used to wipe the ball from right to left, a left and right lateral force will be generated. "Two forces in one" increases the speed and rotation of the ball. 2。 Action essentials (1) When serving, stand on the left side of the table and hold the ball in the palm of your left hand in front of your body. When leading the racket, the left hand throws the ball vertically upward and the right arm rotates outward at the same time. The wrist of the direct grip is abduction, and the wrist of the horizontal grip is abduction, so that the spherical direction is slightly left, the lead is slightly right, and the waist is slightly right. When you catch the ball, your right arm swings from upper right to lower left. (2) When hitting the ball, when the ball falls from the high point to the height of the net, the forearm swings to the upper left, the waist rotates to the lower left, the wrist of the forearm controls the racket, and the middle of hitting the ball rubs to the upper left. (3) After hitting the ball, the arm continues to swing to the lower left and returns quickly. 3。 Note * Adjust the distance of the first landing point of the ball according to the length of the service. * Forearms, wrists and fingers are the main parts, and the waist is the auxiliary part. * After throwing the ball, because the falling speed of the ball is gradually accelerated, it is difficult for scholars to grasp the accurate hitting time and it is easy to miss. This situation can be avoided with practice.
