Table tennis training steps and methods
The steps and methods of table tennis training were as follows: * * 1. Basic Skills Training ** 1. * * Backhand Throw ** - It was easy to get started, and the range of movements was small. The hitting point was in front of the body, suitable for beginners. As the frequency of backhand use in modern table tennis increased, practicing the backhand volley first was beneficial to the formation of other backhand techniques. 2. * * Forehand attack ** - After practicing the backhand drive, he started practicing. Forehand attack was the mother of table tennis skills, and it was also a difficult skill to practice well. Even the world champion needed to practice it daily. 3. * * Combination of backhand and backhand ** - This was the basic technique to play well in the whole table. He began to practice with the forehand attack and backhand kick (one on each side), and then transitioned to the non-fixed point practice. During this process, no force was allowed to be used to prepare for the subsequent backhand and backhand pull. 4. * * Forehand Pull ** - It was the "plus" version of the attack. The leading hand could not be lower than the table. It was necessary to experience the feeling of hitting the board from the back to the front (do not add too much friction first, because modern table tennis does not use much friction), and the feeling of the instant acceleration of the forearm when touching the ball (used to create an arc to pull the ball). 5. * * Backhand anti-loop circle ** - This was a defensive technique. In a match, the frequency of using backhand parries was usually far more than the frequency of using backhand attacks. Only when the backhand defense was stable could one stand firm in the match. 6. * * Rubbing the ball with both hands ** - After the topspin practice was done, he began to practice the backspin. First, practice rubbing and turning, mainly to experience the feeling of the ball staying on the rubber, and at the same time adjust the shape of the board; then practice splitting the long ball, the shape of the long ball slightly erect, the difficulty is to find the jump and click the ball, you need to predict the ball's landing point in advance and in place. * * 2. Multi-ball practice ** 1. * * Single action ** - * * Forehand Backspin **: Pull diagonally, straight, and mid in the forehand position, sideways position, and so on. - * * Backhand backspin **: Pull diagonally in the backhand position, in the middle position, in a straight line, and in the middle position. - * * Forehand Pick Hit **: Pick backspin and backspin in the forehand, middle, and backhand positions. - * * Backhand Twist **: Twist the backhand position and the middle center to twist the backspin and sidespin. - * * Forehand Long Hack, Short Hack **: Slant, straight line long chop and short swing. - * * Backhand Slash Long, Pendulation Short **: Slash Long and Pendulation Short diagonally and in a straight line. - * * Ball Rubbing **: Including fast rubbing, slow rubbing, and diagonally straight rubbing. 2. * * Connecting actions ** - * * Backspin with a forehand (diagonally, straight line) followed by a continuous grab with a forehand (reverse, forehand conversion)**. - * * Backhand backspin (diagonal, straight line) followed by backhand continuous fast strokes (backhand forward, backhand conversion)** - * * Forehand pick (diagonal, straight), backhand continuous fast pull, fast belt, fast whip ** - * * Backhand twist (slanted, straight line), backhand twist, backhand twist, backhand - * * Forehand chop long and then straight, backhand continuous sticking, fast belt, fast tear, fast pull (diagonally straight line)**. - * * Forehand short swing (opponent's direct attack), counter-attack, continuous sticking of forehands, quick tearing, quick belt, quick pull (straight slash)**. - * * Backhand long chop followed by reverse, Forehand continuous stick, quick tear, quick belt, quick pull (diagonally straight line)**. - * * Backhand short swing (opponent's direct attack), backhand continuous stick, fast belt, fast pull, fast tear (straight slash)**. - * * Front, backhand swing, short catch, reverse catch, front hand grab, backhand spin, continuous grab, quick tear, quick belt. ** * * 3. Single practice with multiple balls ** - * * Serve and attack **: For example, if you hit the short ball from the opponent's forehand position or the middle side of the forehand position from the side position, if the opponent twists (splits) to the front of your forehand position, you can perform the following operations: grab and pull diagonally, then continue to pull from the forehand, then switch from the reverse forehand, or grab and pull straight line, then continue to pull from the backhand, then continue to move sideways. During training, you can also use the following methods to help improve your sense of the ball: 1. * * Relaxation Training **: Beginners should pay attention to relaxation in the early stages of learning basketball. Their wrists will be more flexible in a relaxed state. This was because the moment the ball was hit, the nerves were pressed, and the strength of the signal received by the brain was related to the degree of relaxation. It was not beneficial for training to use force to offset the pressure in advance. 2. * * Return to the ball fixed-point training method **: When learning basic skills, you can return the ball in the area drawn opposite the table. The starting area is large, and then gradually shrink. This helps to improve the adjustment ability and ball sense of the hand. 3. * * Borrowing force + reasonable cooperation training method **: Take the backhand practice as an example. When the opponent is pulling the ball, don't just block it with your backhand. You can add techniques such as backhand plucking, tearing, and backhand pulling. In this way, when facing the ball, the backhand should instantly adjust the shape, strength, friction, and so on. 4. "Intentional control of training methods": For example, the "pull through" in table tennis attacking techniques, and the two players continuously putting on short poses and other more difficult training. Only after coming into contact with these tricky balls can they hit the corresponding balls in the game. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

Techniques and methods of shooting table tennis
Here are some tips and methods for table tennis photography: 1. ** Focus ** - When shooting a table tennis match and trying to capture both sides 'faces clearly, using a large depth of field alone might cause problems. You could try to use the multi-point focus function of the camera to set the distribution of the focus points according to the player's position in advance to ensure that the focus could accurately fall on the player's face during the rapid movement. For example, Canon cameras could be set to an area focus mode, and the focus area could be selected according to the approximate range of the player's activities in the scene. 2. ** Light Treatment ** - If it was in an indoor arena with poor lighting and complicated environments, where the flash could not be turned on: - He had to make good use of the light available in the arena. For example, they could find areas in the stadium where the lights were more concentrated and evenly distributed. If there was a side light, the side light could be used to highlight the outline of the player and increase the layering of the picture. - Increase the camera's sensitivity (USB) to increase the brightness of the image, but pay attention to controlling the noise. Different cameras had different noise levels at high Iso. For example, some Nikon models had better noise control below Iso 3200, while some Canon cameras might have acceptable noise levels between Iso 1600 - 3200. The appropriate value could be determined through shooting tests. 3. ** In terms of composition ** - He used the technique of comparing size and composition. For example, comparing the size of the table tennis ball with the player's body or racket would highlight the small size of the table tennis ball and the tension of the game. He could also compare the player with the entire table and the surrounding environment to show the state of the character in the scene. - Using static and dynamic comparison. The speed of table tennis was very fast, but the players were relatively still when they were ready to serve or receive the ball. Capturing such a moment could form a contrast effect between movement and stillness, increasing the interest and attractiveness of the picture. 4. ** Motion-Capture ** - In order to clearly capture the trajectory of the table tennis ball and the movements of the players, a fast shutter speed was needed. Generally speaking, the shutter speed should be at least 1/500 of a second or even faster, depending on the speed of the table tennis ball. However, increasing the shutter speed might reduce the amount of light entering, so it was necessary to adjust the aperture and the aperture. - Predict the player's movements in advance. Knowing the basic rules of table tennis matches and the common strokes, such as serving, spiking, pulling the loop, etc., could make preparations for shooting in advance at the position and time of the action, thus increasing the success rate of shooting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are the contents of table tennis training response?
The table tennis training response mainly included the following aspects: 1. [Pre-judgment Awareness]: In table tennis, whether it is the starting or receiving part, pre-judgment is very important. Through observation and analysis in the game, he had to measure the common skills and habits of the opponent, such as serving, receiving, and snatching the ball, so as to adopt the corresponding combination of countermeasures. Pre-judgment was better than natural reaction. A good pre-judgment could help athletes prepare in advance. 2. [Consciousness of staring at the ball: This is the basis for correct judgment of the ball's path.] After each round of cricket, players had to pay close attention to the shape of the opponent's plate, friction, arc, and hand movements. Especially when judging the up-and-down spin ball, you can use the elimination method. For example, when the racket touches the ball, the racket faces backward and there is a downward or side-down movement, it is a down-spin or side-down spin ball; Other than that, it can be judged as a top-spin ball (the way of receiving the ball is basically the same, and can be excluded from the down-spin). At the same time, the strength of the down-spin can be judged according to the force exerted at the moment of hitting the ball and the angle of the racket face. The greater the downward force, the more the racket faces backward, and the greater the strength of the down-spin. 3. [Movement Awareness]: There is a saying that goes,'Three-point technique, seven-step technique'. The movement of footsteps is a powerful guarantee to gain the initiative and attack first. Common footwork included side jump, side step, break step, single step, stride, slide step (jump step), cross step, and so on. 4. ** Awareness of adjustment **: Different tactics should be used for different incoming balls. Regardless of whether he used reverse glue or long glue, or whether he used picking, pulling, pulling, pushing, rubbing, knocking, and other techniques, the key was to adjust the fingers, plate shape, strength, and direction according to the up-and-down spin of the incoming ball. He had to accurately hit the middle, middle, and lower parts of the ball, and he had to be able to adjust the accidental balls such as brushing the net and brushing the edge. 5. ** Rubbing Awareness **: Playing table tennis involves two basic forces, namely the force of hitting the ball (hitting) and the force of rubbing the ball (rubbing). Except for the high ball near the net, which could be simply hit, hitting other balls required a combination of hitting and rubbing. 6. Quality Awareness: The elements that represent the quality of table tennis include strength, speed, strong rotation, and tricky landing points. 7. Connection (Conversion) Awareness: Connection (also known as combination) focuses on speed and conversion, such as plate shape conversion (such as pushing left and attacking right), center of gravity conversion, attack and defense conversion (such as receiving, sending, and holding), combination of pulling and shooting, combination of pulling and rushing, etc. To integrate the previous cricket ball with the next cricket ball, improving the stability of this link would help to play to one's own advantages. In the defense and attack conversion, the ball inside the ring would be picked up when there was an opportunity, and if there was no opportunity, it could be tilted or swung. The purpose was to grab the ball in the next plate. 8. [Reflex Arc Training: The human nerves can be trained to shorten the response time of the reflex arc.] During training, practice more high-speed balls, such as multi-ball training, so that the ball speed is too fast to cope with. After a period of practice, you will be more adapted to the slower ball speed. You will be able to react in time during the game and reduce the possibility of retreating. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Teaching and Training of Backhand Pull in Table Tennis
The following is the teaching and training method of table tennis backhand pull: ** 1. Hold the racket ** He used a backhand shallow grip, holding the racket against his index finger and leaning the thumb. This way of holding the racket was good for adjusting the racket face, which not only ensured better control of the arc when pulling the ball, but also made the whole force more smooth. However, you should pay attention to avoid holding the racket too much to the backhand. Otherwise, it may affect the rapid conversion of the movement when switching to the forehand. ** Two, backhand topspin ** 1. ** Prepare the posture ** Standing on the left half of the table, you can step back slightly at the beginning of the practice, about 80 centimeters to 1 meter away from the table, and at the same time, keep a heavy heart. 2. ** Lead Auction ** The head of the racquet was placed on the left hip instead of the hand extending to the left. There was no need to turn the waist like the forehand, only the left hip was retracted and the right shoulder was slightly forward. The center of gravity of the two feet should be on the front foot. His wrist was bent inwards, but not excessively. 3. ** Hit the ball ** He pushed his left knee forward while stretching his abdomen. However, he did not need to stand straight. He just needed to push forward slightly. Then, he accelerated his forearm and spread it to the front right. He hit the ball at the later stage of the ball's rise and touched the upper left part of the ball. The moment he touched the ball, his thumb and index finger grabbed the ball board tightly. His thumb could add a feeling of pushing forward and down. After hitting the ball, when the head of the racket was pointed at the diagonal angle, it instantly stopped and returned to the preparation position. ** 3. Backhand backspin ** 1. ** Lead Auction ** The lead should be slightly lower than the topspin ball and placed in front of the inside of the left thigh. 2. ** Hit the ball ** When you touch the ball, you can touch the left side of the middle or the left side of the middle and lower part. When you touch the ball, you have an upward "up" force, and then press the arc. The forward drive loop had more force and more impact, while the spin loop had more friction and stayed on the board for a longer time. ** 4. Training Method ** 1. ** Experience the feeling of rubbing upwards (transition from backhand to backhand)** When learning the backhand continuous fast pull, you can transition from the backhand kick. If the ball comes with a bit of backspin, it will fall into the net with the poaching action. At this time, the students were required to slightly lower the racquet to the bottom of the table, and then use their arms to exert force upwards. Although they might not feel the strength of twisting the waist, they could understand the feeling of creating friction upwards to turn the downspin into a topspin. 2. ** Experience the feeling of the center of gravity rubbing your arms upwards ** In front of him was a short wooden chair with a rebound board. He let go of the ball and let it bounce freely before pulling it up onto the stage. Because the backhand pull rubbed against the ball during the fall (early or late fall), the ball had to be pulled up when it felt like the ball was falling low. You can prepare more than one bowl of balls to practice. When you pull the ball, the ball will bounce down and the center of gravity will be lowered. Your arms will exert force upward to experience the feeling of your body's center of gravity driving the upward swing. 3. ** Intensified Training ** - ** Multi-ball and single-ball training ** After experiencing the feeling of rubbing the ball upward through the previous two methods, he first increased the stability of the swing through multi-ball training during the continuous backhand pull, and then continued the single-ball continuous pull training. - ** Correct use of waist and hip ** When practicing multiple balls, you have to experience the change of center of gravity. When pulling the ball with a backhand, the center of gravity should always be tilted forward. You can't push your stomach forward and put your center of gravity behind your buttocks. When continuously pulling, one had to use the strength of the waist (abdomen, abdomen), similar to the feeling of twisting a towel. He had to use the non-holding hand to assist him in twisting forward. He had to experience the force exerted on his right abdomen. The entire force exerted felt like boxing, but it was not the force exerted from the front and back. Instead, it had the force of twisting and pushing forward. He could also assist in pushing forward with his right hip and knee to gradually make the force exerted more coordinated. 4. ** The correct use of the wrist ** When you catch the ball and turn it, your wrist should be tight. Your forearm should send the ball out to extend the arc. Don't shake your wrist. You should have the feeling of catching the ball. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Three must-learn serving methods in table tennis
Here are three ways to serve in table tennis: 1. Forehand flat serve: This is the most basic serve method for beginners, and also the foundation for mastering other complicated serves. The speed of the ball was average, with a slight topspin, which was easy for the opponent to return, which was convenient for practice in connecting the ball with the forehand attack or backhand push. The main point of the action is to throw the ball up with the left hand, and at the same time, rotate the right arm inward, so that the racket face is slightly forward, and the racket is pulled to the right. When the ball descends from the high point to slightly above the net, the upper part of the ball is shot to the left. However, beginners were prone to problems such as not throwing the ball, hitting the ball inside the table, or breaking the rules. 2. Counter-rotating serve: This is a relatively popular serve technique in the world of table tennis, which appeared in the late 1990s. It could enrich the rotation of the serve and increase the difficulty of the opponent's judgment of the rotation when receiving the serve. It was suitable for people who had the ability to attack with a backhand. Compared to the normal serve, the height of the ball was different. The normal serve was close to the waist, while the reverse spin serve was close to the chest. By rubbing different positions of the racket, the topspin ball, the backspin ball, the side topspin ball, and the side backspin ball could be sent out. Among the many players, Zhang Jike and Fan Zhendong were the typical representatives of this serve technique. 3. ** Forehand serve with a right side topspin and rapid long ball (running ball)**: This serve has fast speed, long landing point, large angle, strong momentum, low flight arc and slanted to the left, with a strong right side topspin. If you want to form a stalemate with the other party in the middle or far distance, or if you are facing an opponent who is good at rubbing attacks, this kind of serve is more effective. The main point of the action is to throw the ball up with the left hand, and at the same time, rotate the right arm inward, so that the racquet face is slightly forward, the forearm wrist naturally droops, the elbow joint is higher than the forearm, and the racquet is pulled to the right. When the ball dropped from the high point to the height of the net, the right side of the ball rubbed against the right side. The moment the ball touched the ball, the thumb pressed down and the wrist shook from the right back to the left. When serving, it is mostly inclined and straight lines. The angle is required to be as large as possible, and sometimes it can be coordinated to the opponent's middle.

Table tennis trainer self-training artifact installation
The installation method of the table tennis trainer is as follows: 1. ** Prepare tools **: You need to prepare basic tools such as a screwdriver, a hammer, and a wrench. Take out the parts of the table tennis trainer one by one to ensure that the quantity is complete. 2. ** Choose a suitable venue **: The ball machine needs to be placed on a flat ground with enough space to accommodate the ball machine. When installing it, it should be kept away from direct sunlight to prevent the ball table from being damaged due to exposure to the sun. The trainer should be kept well-vented to avoid corrosion caused by a humid environment. It is best to choose a spacious venue to avoid collision with other furniture and items. 3. ** Mount the ball machine (if it is a trainer with a ball machine)**: According to the instructions of the ball machine, install the main body, power supply, control panel, and other parts of the ball machine. Pay attention to the height and angle of the ball machine during the installation process. If it is a suspended table tennis trainer, the installation is as follows: - To determine the installation location, it is generally recommended to install it about 2.7 meters from the ground to ensure the bouncing effect of the ball and spring. - After selecting the installation location, you can use the electric drill and expansion pipe to drill the hole on the ceiling. Note that the drilling depth needs to be determined according to the length and diameter of the expansion pipe. - He inserted the expansion tube into the hole and fixed the hook to the ceiling with a Screwdriver. He took a spring of moderate length and fixed one end to the hook and the other end to the trainer. Then, he adjusted the length of the spring to hang the trainer at the desired position. 4. ** Main body of training device installed (using normal training device as an example)**: - He inserted the rigid thin rod into the bottom disk. He had to insert it tightly, or else it would easily come out. - A slightly thinner elastic rod was installed on the rigid rod. The length of the elastic rod determined the swing range. - Set up the training device to confirm if it fits properly, otherwise there will be a safety hazard. - For some table tennis trainers with electric functions, it was necessary to ensure that the voltage of the power socket was consistent with the requirements of the trainer. Before connecting the power, it was necessary to carefully check whether the trainer was damaged or short-circuited to avoid safety accidents. 5. ** Mount the upper part and the ball tube (if there is one)**: Mount the upper part of the training device on the rack and fix it properly (be careful not to turn it upside down). Finally, install the ball tube on the training device and use it. 6. ** Adjusting the angle and speed (if there is such a function)**: Usually, the table tennis trainer has a corresponding knob or button. By adjusting these control devices, you can change the shooting speed and angle of the ball. When making adjustments, you must set the appropriate parameters according to your training level and purpose.

The difference between training table tennis and other balls
There were many differences between training table tennis and other balls. From a star-rating perspective, training balls were generally one or two-star, while large-scale competition balls were three-star. In terms of performance, table tennis was unique compared to other ball games. Its speed was fast, and it required players to judge and react to the rotation, speed, landing point, strength, etc. of the ball in an instant. It required a high reaction speed. Compared with basketball and tennis, table tennis was mostly played indoors. It was less affected by the weather. The amount of exercise was large but not as intense as basketball, so it was not easy to get injured. In terms of materials, the early table tennis balls with seams were made of Cellulosic Acid, which had a better grip on the ball. The bounce was similar to the old Celluloid ball, but it was easy to break, especially at the joints. Its service life was shorter. Now, it was mostly replaced with ABS engineering plastic, which made the ball more resilient. In addition, table tennis was divided into big balls (40mm in diameter) and small balls (38mm in diameter). Now, big balls were used as the standard ball in all levels of competitions, and small balls were no longer used in formal competitions.
