What are the postures and movements of table tennis preparation?

Table tennis, before hitting the ball, you must concentrate all your attention and judge clearly the hitting point, speed and rotation nature of the incoming ball; Then quickly move the footwork and choose a reasonable hitting position; Take the corresponding hitting action so as to return the ball accurately and effectively in the future. This requires a ready posture before hitting the ball. Good preparation posture is conducive to getting started quickly, taking care of the whole table and using various techniques to return the ball.

The preparation posture is the basic posture and body posture suitable for you to play in the game. Body posture is a reasonable posture that an athlete keeps when hitting the ball. Preparation posture is the premise and foundation of table tennis technology, which directly affects the development of technology and is also an important factor to determine the outcome of the game. The preparation posture mainly serves the footwork, creating conditions for speeding up the start and improving the accuracy of hitting the ball, so that it can give full play to the coordination of the whole body, arms, waist, lower limbs and other parts to achieve the predetermined purpose.

Preparation posture includes body posture and standing posture.

(1) Body posture

Feet are shoulder-width apart or slightly wider than shoulders, knees are slightly bent, forefoot touches the ground (mainly with the inside of feet touching the ground), toes are slightly pressed, heels are slightly off the ground, and the center of gravity is placed between the feet. The upper body leans forward slightly, abdomen is closed, the arm holding the racket is naturally bent, the elbow holding the racket is slightly outward, the racket is placed in the right front of the abdomen, the wrist is naturally relaxed, the racket head refers to the right front, and the elbow holding the racket horizontally is downward. Keep your eyes on the ball.

(2) People who hit different positions have different standing postures.

The position of backhand left push right attack is generally that the left foot is slightly ahead of the right foot, and the position of the left foot is basically on the extension line of the left line of the table. The distance from the body to the end line of the table is about 40 cm.

The positions of backhand attack and cross attack are basically the same as above, but the body is about 50 cm away from the end line of the table. The position of backhand loop ball is that the left foot is in front and the right foot is behind, and the left foot is basically about 25 cm outside the extension line of the left line of the table. The body faces the left corner of the opponent's table, about 60 cm away from the left corner of the table. The left foot can be slightly in front of the right foot, or the two feet are basically parallel, and the position of the left foot is basically on the extension line of the left line of the table. The distance from the body to the end line of the table is about 65 cm.

The defensive position (including the combination of cutting and attacking) is that the two feet are basically parallel, and the left foot position is on the extension line of the left line of the table. The distance from the body to the end line of the table is about 1 m.

Common mistakes in preparation posture and their correction methods

1. The legs are too wide, the hips sit back, the posture is stiff, and the whole foot touches the ground, which affects the start. The reason is that we don't know the correct action. Although the width of standing posture can increase the support surface of two feet, and the center of gravity of the body is lower and more stable, it affects the flexible start and the start speed is slow. Correction method: explain the main points clearly, the teacher demonstrates from the front, emphasizes that students should master the correct movements in practice, and suggests that the distance between feet is moderate, knees are buckled, the upper body is slightly tilted, the chest is folded, the abdomen is closed, and the ground is touched with the inside of the forefoot. Practice in pairs, correct each other's wrong movements, do fast foot lifting exercises with password signals, and listen to the password in situ to do preparatory posture exercises for sprints.

2. The feet are too narrow, the upper body is too straight and the center of gravity is too high. Bend over without bending your knees. Too narrow is caused by insufficient mastery of correct movements, fear of fatigue and poor leg strength. Although it is too narrow, it can reduce the support surface and start relatively fast, but it has poor stability in hitting the ball. Corrective methods: First, do more low-key exercises. Face to face, two people do the speed competition practice of unarmed squat posture behind the stage (half a minute or one minute, whichever is more). Do more leg strength exercises and weight-bearing exercises. Pay attention to cultivating the spirit of hard struggle.

3. The feet are splayed, the posture is stiff, the movements are uncoordinated, and the center of gravity moves backward. It is easy to make mistakes such as unstable center of gravity, untimely trampling, slow start and not in place. The main reason is that the understanding of mastering correct movements is rather vague. Corrective methods: do more exercises in usual practice and teaching and training to relax the in-situ fretting state; Listen to the password to do preparatory posture exercises when running or marching in place; The two of them practiced walking face to face and observed each other's actions to correct mistakes.

footwork

Zhuang Zedong, a famous table tennis player in China, pointed out: "The starting point and source of strength of every stroke are the feet and legs. Footwork is the basis of exercise. " In table tennis training, we often pay attention to the technical training, but ignore the footwork training. In the game, the landing point of the incoming ball is ever-changing, and the quality and accuracy of a player's footwork will directly affect the quality and accuracy of hitting the ball, thus affecting the improvement of technical level. With the continuous development and perfection of table tennis, it is impossible to meet the needs of training and competition without flexible footwork.

Footwork is the life of table tennis. So what is footwork? Footwork refers to the footwork moving method adopted by the batter to choose the appropriate hitting position. Its characteristics are: fast start, fast movement and fast frequency. It is the hub for timely and accurate use and connection of various technical actions, and it is also a powerful guarantee for the implementation of various technologies. Many times, the poor quality or mistakes of the return ball are due to the poor adjustment of footwork, but people often hold the technical responsibility. According to the analysis of table tennis statistics, if each game moves 100-250 times, the moving distance is about 1000-3000m. This shows the importance of footwork, which is closely related to physical fitness. Therefore, we should attach importance to and strengthen the table tennis footwork training for teenagers and beginners.

The distinction of table tennis footwork: in terms of moving range, there are three different ranges: large, medium and small. From the moving direction, there are different moving directions such as forward, backward, left and right, oblique front and oblique rear. From the way of movement, there are one foot, two feet and cross movement. In terms of moving forms, there are translation, sliding and jumping. Its types are: skip, single step, stride, step, stride, small step and so on.
