In tennis professional competition, why do players have to change their rackets after a few beats?

A golfer named Tom G wrote such a thing on the Internet. He has used the same tennis racket for many years and recently bought a new one. The length, weight, balance and threading pounds of the new racket are exactly the same as those of the old one. The only difference is that the size of the grip is one size smaller, because he heard that a small grip helps to make more spins. After using his new racket for a period of time, he found himself suffering from tennis elbow. It is easy to associate. After playing tennis for so many years, I feel no discomfort. Why do you get tennis elbow after changing a new racket? Does this have anything to do with changing rackets? Changing tennis rackets often increases the risk of injury? At first glance, such doubts seem unreasonable. Because there is little difference between the new racket and the old one, it seems unlikely that a slight change in grip will have such a big impact. In addition, tennis elbow is not an acute injury such as fracture, but a long-term chronic injury.

it seems unreasonable to blame the tennis elbow on the new racket. As we all know, every grip has a suitable hitting point and hitting height. So when playing, should we change the grip according to the height, bounce, rotation and the desired hitting effect of the ball? Let's talk about this problem! Content of this issue: Will you change your grip when playing? 1. forehand grip muscle memory Because of the long time of playing, the usual grip will lead to a certain muscle memory when the wrist hits the ball. Take the semi-western grip as an example, the wrist is stretched when hitting the ball. Is it necessary to change the grip according to different goals when hitting the ball? If you turn your hands counterclockwise to change your grip, your wrist will still be stretched by muscle memory, which will lead to the face opening when hitting the ball, out of control and easy to go out of bounds. Changing the grip clockwise will cause the racket face to close when hitting the ball, and it is easy to get off the net when hitting the ball.

In the same way, if the usual grip is the East or the West, the racket face will change when changing to other grips, and even the unfamiliar grip will lead to the deformation of the hitting action, which will ultimately affect the hitting effect. Is it necessary? It takes some time to change the grip, and it is not necessary to change it unless there is enough time or there will be obviously different hitting effects between different grips. Baseline hitting is fast, and changing grip will shorten hitting time. Federer, Nadal, Deyo and other professional players have also proved through their own actions that any east, half west or west grip is enough to deal with balls with different heights and different spins, and can also achieve the desired hitting effect, whether it is fast or spinning ... so it is of little significance to change. However, things are not as simple as imagined.

experienced golfers know that tennis is a very special sport, which requires high concentration, stable psychology and harsh external conditions. Small changes in these three aspects will have an impact on hitting the ball. As far as my playing experience is concerned, with the growth of the ball age, I am more and more sensitive to the details of the racket, and any slight change will make me feel uncomfortable. For example, the change of the number of pounds of threading and the thickness of the sweat-absorbing belt, or even the change of the sweat-absorbing belt from frosted to sticky, will affect my hitting. For those who are used to installing shock absorbers on rackets, once the shock absorbers are lost in the game, the rhythm of the game, the feeling of hitting the ball and even the mentality will be more or less affected.
