The swing of the table tennis is the act of waving the racket with the gesture made in the state without the ball, and the batting is the act of transmitting the energy generated by the swinging to the ball. The swing of table tennis includes stroke short blocking smash push roving drive cut back smashback drive back short back push fly. A considerable degree of stability is required to improve the accuracy of the ball. Foot legs waist, wrist arm, shoulders, etc., move organically, and you have to beat the rhythm to create a smooth and accurate swing posture. For beginners who are learning ping pong, they will take lessons from 5 to 20 minutes and practice the swing posture personally while watching the mirror. Use a racket you are currently using or a practice table tennis racket that is twice as heavy as a regular racket on the market. In this way, when you practice swing posture, the correct posture at the time of receiving the lesson will be retained at first, but as the number of swing increases, the swing posture becomes scattered. In the end, you can not use your feet, legs, wrists, arms, and shoulders organically and use your arms and shoulders to practice your swing. It takes a lot of time to form an accurate swing posture and you lose interest in table tennis. Also, it is necessary to improve the swing speed and the power to improve the swing speed by strengthening the muscular strength through the swing practice, and it is difficult and time consuming to get the effect in this way. In addition, a person with a middle or higher level of skill may have a stronger force than the strength of his or her swing when playing a table tennis game. Eventually, it often leads to injuries.

It is an object of the present invention to accurately recognize the starting point and the ending point of the swing in the conventional swing practice. Therefore, the trajectory of each swing is different. In practicing the exact swing posture of the table tennis personally, the swing trajectory to the starting point and the final point which can recognize the first posture can be performed even if the number of swings increases, and the swing practice can be performed so that the posture is not scattered. It is also intended to provide an exercise table tennis racket capable of enhancing the swing speed, the power of the swing force, and the injury caused by the excessive swing by strengthening the muscle strength through the swing practice.
