Description

Table tennis backhand swing trainer

Technical Field

The utility model belongs to the field of sports, and particularly relates to a device for assisting learning of table tennis backhand attacking technology.

Background technique

The backhand attack techniques in table tennis mainly include: horizontal backhand attack and straight backhand backhand attack techniques, etc. These techniques are difficult to master, especially when you are just starting to learn backhand techniques. You need to do a lot of imitation exercises to form dynamic stereotypes, so as to master the correct technical movements. The current backhand attack imitation action practice methods mainly include bare-hand imitation and hand-held racket imitation technique swing exercises. The horizontal backhand attack swing technique mainly includes: the two feet are almost parallel, the racket is led to the left position in front of the abdomen, and the wrist controls the racket to lean forward at the same time, and the wrist and forearm are used to swing to the upper right front, and the swing stops at the upper right front of the body, and then the racket is restored, and the above action exercises are repeated. The straight backhand backhand attack swing technique mainly includes: the right foot is slightly forward, the center of gravity is slightly close to the right foot, the index finger is slightly relaxed, the racket is held, and the thumb is pressed down to make the racket shape lean forward. Turning the waist drives the arm to swing naturally forward and upward, and the swing stops at the upper right front of the body, and then the racket is quickly restored, and the above action exercises are repeated. When beginners practice backhand attack technique, they often make mistakes in swinging the racket, such as: the forearm is not in place, the racket shape is not well controlled, and the arm holding the racket is not in place when the action is restored. After repeated intensive practice of wrong movements, the wrong stereotyped movements are difficult to correct, which affects the mastery of correct technical movements. In addition, because the single repetitive imitation movement is boring, the practitioner is prone to boredom. Such practice is easy to discourage the practitioner's enthusiasm for learning, and the practice effect is not good, so the purpose of quickly mastering the table tennis backhand attack technique cannot be achieved.

The method of using the utility model is as follows: when using the utility model, the training device is fixed at the sideline of the table tennis table according to the content of the backhand attack swing practiced by the user, and the positions and angles of the starting board and the stopping board are adjusted. The practitioner uses the starting board to assist in fixing the starting position of the swing, uses the stopping board to assist in fixing the ending position of the swing, and uses the inclination direction and angle of the stopping board to regulate the racket angle when the racket swings to the end after the backhand attack, and repeatedly performs the swing practice.

Example 1: Use the trainer to assist in practicing the technique of swinging the backhand attack with a horizontal racket near the table: adjust the horizontal arm of the trainer to the vicinity of the end line of the table as shown in Figure 3, and adjust the positions of the starting board and the stop board and the angle of the stop board. The practitioner stands with his feet almost parallel, stands near the horizontal arm of the trainer, holds the table tennis racket in his hand, leads the racket to the front of the abdomen, and lets the racket touch the starting board, with the wrist slightly bent. While the waist and hips are slightly turned to the right, swing the racket to the upper right front with the wrist and forearm, and at the same time control the racket to tilt forward with the wrist, swing until the racket touches the stop board and quickly return to the original position. Repeat the swinging exercise in this way, and after the horizontal racket backhand attack action is familiar, transition to multi-ball and single-ball exercises. Note that at the moment when the racket touches the stop board, the shape of the racket is consistent with the inclination angle of the stop board, and when returning to the original position, the racket is retracted until it touches the starting board.

Example 2: Use the trainer to assist in the practice of backhand backhand attack technique at a far table: adjust the horizontal arm of the trainer to the far end line of the table, and adjust the position of the starting board and the stop board and the angle of the stop board. Stand near the horizontal arm of the trainer, with your right foot slightly forward and your center of gravity slightly on your right foot. Relax your index finger slightly, hold the racket, and press down with your thumb to make the racket lean forward and touch the starting board. Turn your waist to drive your arms to swing forward and upward naturally, and quickly return to the starting board after the back of the racket touches the stop board. Repeat the swinging practice in this way, and after you are familiar with the backhand backhand attack action of the straight racket, you can then transition to multi-ball and single-ball practice.
