What is the swing weight of a tennis racket? What effect does the swing have on the players?

Weight and balance are the two most important factors that affect the performance of the racket. Here is a common sense about weight: generally speaking, a heavier racket can produce more swing force, be more stable and transmit less vibration than a lighter racket; Lighter rackets are more flexible, so players who use them swing faster. However, it should be noted that the lighter the racket, the more convenient it is to use. In reality, although the lighter racket is easy to swing, its hitting power is often weak.

"The racket is an extension of the arm." I believe many people have heard this sentence. Yes, when discussing the weight of the racket, besides discussing the net weight of the racket itself, we should also add one of the most important data: the swing weight. But many people only know the terminology, and seldom know the real data meaning represented by the terminology. Today, let's talk about the important index of tennis racket-swing weight.

Then, can a lightweight racket with a faster swing speed produce the same strength as a heavyweight racket with a slower swing speed? From 65438 to 0990, Wilson Company developed a series of rackets with sledgehammers, which gave a positive answer to this question. Wilson's hammer technology reduced the overall weight of the racket by 1-2 ounces, but tried to increase the weight of the racket head and turn the balance into "head weight". Due to the weight reduction, the flexibility of the racket is improved; When the weight of racquet head increases, the swing strength will not decrease. Now all major brands have this kind of racket with light weight but balanced head and weight.

The swing weight will not be printed on the racket. Want to know the swing weight of a racket, you can look it up on TW, but TW is only the swing weight of a racket, and the real swing weight of each racket is not exactly the same. So the best way is to measure it yourself. Let's talk about how to test the swing weight of the racket: the instrument for testing the swing weight is a swing weight meter;

I believe many people here will think that even if we know the concept, it doesn't make any sense to actually play ball, so let's talk about the impact of the swing weight of the racket on hitting the ball first: for convenience, we only discuss the swing weight data here, assuming other factors are the same.

In this case, the higher the swing weight of the racket, the higher the stability of the racket at the moment of hitting the ball, that is, the smaller the shaking of the racket, that is, the smaller the vibration transmitted by the racket to the wrist at the moment of hitting the ball, and the more friendly it is to the arm. However, this does not mean that the higher the swing weight, the better. The strength of the user determines the swing weight of the racket. The heavier the swing, the slower the swing speed. If the strength is insufficient and the racket head can't get a strong acceleration, it can't hit the ball with speed and rotation at the same time.

However, when the swing weight is too low, the racket will shake even more at the moment of hitting the ball, and it is impossible to push forward and penetrate the ball. At the same time, if the swing weight is too low, it will increase the chance of arm injury.
