Why should we increase the counterweights to tennis rackets?

 

The purpose for us to add counterweights to something is to maintain the properties of balance, and to keep its good controllability performance during using. It’s the same purpose for the tennis rackets, adding counterweights are mainly to increase the ball hitting balance when we use the tennis rackets, to ensure that the user has a good controlled grasping intensity of the hitting process. The point of tennis rackets balance, that is the center of gravity of the tennis racket, the balance point and the midpoint of the racket are proportional to the swinging power. According to the mechanics principle, the tennis rackets which have the same balance, if the weight of the rackets are grater, then the swinging power will be also greater; on the contrary, if the weight of the racket is smaller, then the users’ swinging power will be lower.

 

The controlling of the swinging power plays a vital role in the games for the players. Studies have shown that, for the two same weight tennis rackets, if the balance of the racket is closer to the racket head, then the swinging power would be greater. However, due to the characteristics of individual differences,  it is impossible for two players to use the same weight tennis rackets to hit the ball with the same intensity. Thus, if the players who come from the different countries use the same weight tennis rackets will make them difficult to exert their best performance in the games. So it seems to be necessary to increase the suitable weight counterweights to tennis rackets.
