What are the preparation postures for playing table tennis?

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.
