Description

Table tennis backhand attack ball swing and bat training device

Technical Field

The utility model belongs to the field of sports, and particularly relates to an instrument for assisting in learning a table tennis backhand ball tapping technology.

Background

The table tennis backhand attack technique mainly comprises the following steps: the techniques of horizontal shooting of backhand ball attack, straight shooting of backhand ball attack and the like are difficult to master, and particularly when the technique of backhand ball attack is used for beginner, a great deal of imitation action exercise is needed to form dynamic shaping, so that the correct technical action is mastered. The currently adopted method for practicing the counter-handed attack ball imitating action mainly comprises freehand imitating and hand racket imitating technical action swinging practice. The technical action of the transverse shooting and reverse-hand attack ball swing shooting is mainly as follows: the two feet are nearly parallel to open, the hand-held racket is led to the position of the front left of the abdomen, the wrist controls the racket to tilt forwards, the wrist and the forearm are swung with force to the right front upper part, the swing is stopped to the right front upper part of the body, and then the hand-held racket is restored, and the action exercise is repeated repeatedly. The swing shooting technique of the direct-shooting reverse-hand reverse-side attack ball mainly comprises the following steps: the right foot is slightly forward, the center of gravity is slightly close to the right foot, the index finger is slightly relaxed, the ball board is taken with the thumb forcefully pressed downwards, and the board is tilted forwards. The waistband is rotated to swing the arm to the front upper part naturally, the swing is stopped at the front upper right part of the body, then the waistband is quickly restored, and the action exercise is repeated repeatedly. Beginners often experience wrong swing motions when practicing the reverse hand ball tapping technique, such as: the forearm is not in place, the shape beating control is not good, execution of filming arms are not in place when the action is restored, and the like. After repeated false action strengthening exercises, the formed false shaping actions are difficult to correct, and the mastering of the correct technical actions is affected. In addition, because of single repeated imitation action, boring and boring, the exerciser is easy to generate tired psychology, so that the learning enthusiasm of the exerciser is easy to be eliminated by exercise, the exercise effect is poor, and the aim of rapidly mastering the table tennis backhand attack technique is not achieved.
