The difference between 3U and 4U badminton rackets

What is the difference between badminton racket 3U and 4U? Many badminton enthusiasts have had such questions, and even some old stadium drivers who have been playing for several years are difficult to explain the detailed difference between badminton rackets 3U and 4U. The U in badminton rackets 3U and 4U represents the racket weight, but what is the difference between 3U and 4U badminton rackets? How big is the difference between the two? How do we choose 3U and 4U badminton rackets? The following Chutian Sports Channel editor will answer the difference between badminton racket 3U and 4U in detail:

The U in badminton rackets 3U and 4U represents the weight of the badminton racket. Tracing the development of badminton rackets, after the advent of carbon badminton rackets, after several young quantitative trends, badminton rackets finally exceeded the empty racket weight of 100 grams. To commemorate this historic progress, badminton racket manufacturers use 100 grams as a base and use a value that deviates by 100 grams to express the weight of carbon rackets. And this unit that deviates by more than 100 grams is U, and the U number refers to the weight of the badminton racket.

The weight of badminton rackets is diverse. Each racket is clearly marked with its weight, and the weight of the general badminton racket is divided into five levels: 1U\2U\3U\4U\5U. As with the size unit of the racket, different manufacturers have their own definition of weight unit, but the popular one is the U system used by YONEX. Weight range: 1U: 95-100g, 2U: 90-94g, 3U: 85-89g, 4U: 80-84g, 5U: 75-79g, so according to the U system standard, a 3U badminton racket is about 4g heavier than a 5U badminton racket.

The weight of aluminum frame badminton rackets is generally more than 1U (95-99 grams), and there are a few full-carbon badminton rackets with a weight as low as 80 grams called super light rackets, which are mainly designed for women, or golfers with special needs. More than 95 grams are generally metal rackets, mainly for people who play badminton as a fitness means and do not want to spend too much on equipment. The weight range of badminton rackets generally sold on the market is basically between 2U-4U.

The difference between badminton rackets 3U and 4U is simply different weight, under the same balance, the weight difference between 3U and 4U lies in the carbon yarn content of the head frame, both the same balanced two rackets, the yarn content of 3U badminton rackets is several grams more than 4U. The weight rod inside the wooden handle is used to adjust the weight and balance, if the head is heavy, add a carbon rod to the wooden handle, and the head is light to be glued in the shooting frame.

Since the difference between badminton rackets 3U and 4U is weight, some people may ask, then choose a light weight 4U badminton racket. In fact, the badminton racket is not the lighter the better, the badminton racket is light and the swing speed is fast, but it will feel useless when smashing the ball, which will affect the power of the shot. On the contrary, badminton players with relatively small strength choose too heavy rackets, not only can they not reach the desired speed when swinging, but they will be particularly tired when fighting.

Ditto, that is, when it comes to badminton rackets 3U and 4U, how should I choose? When badminton enthusiasts choose a badminton racket, the key is to choose according to their own strength. The heavier racket (3U) is suitable for players who are strong and offensive, and the lighter racket (4U) is more suitable for players who are more defensive. The heavier the badminton racket, the greater the inertial force, the lighter the badminton racket and the more flexible it is to use. Therefore, if your wrist strength is strong enough, you can choose a heavy 3U badminton racket; If you are a girl or have little wrist strength, then a 4U badminton racket is recommended.
