What's the speed difference between badminton 76 and 77? What kind of ball should beginners choose?

76 is more suitable for defensive type and 77 is more suitable for offensive type. Beginners can generally choose 76 balls, because this kind of ball is slower and more suitable for novices.

According to the rules of the World Badminton Federation badminton competition, the weight of badminton is 4.74 grams to 5.50 grams ... In the past, the corresponding weight was often used to express the ball speed. For example, balls weighing 4.9 grams and 5.0 grams will be labeled 49 and 50 respectively. There are also European units of weight expressed in grains, such as 77 grains (green) and 78 grains (green).

At present, the YONEX brand commonly used in international competitions is often marked with simple numbers from 0 to 5. The smaller the label, the lighter the ball and the slower the ball speed. On the contrary, the heavier the ball, the faster the speed.

At present, the international standard is marked with green, and 76 77 78 79 units on the barrel are all green, which is the most widely used. The smaller the value, the lighter the weight.

In China, the ball speeds are mostly 76 and 77 greens, 77 greens below 30℃ and 76 greens above 30℃.

Extended data:

Badminton, usually a court game for two or four people, uses a handle racket to hit a feathered ball across the net in the center of the court in turn.

Badminton is made of cork or sponge, with feathers (natural or artificial) arranged at the bottom, which can be hit with rackets. Because they were originally composed of feathers, they were called badminton.

The weight of the ball is 4.74g ~ 5.5g, and 65,438+06 feathers are inserted in a hemispherical cork tray, with a height of 68-78mm and a tail diameter of 58-68mm, which is divided into 65,438+0-65,438+00.

The scoring system adopts the scoring system of 2 1, that is, the first score of both sides reaches 2 1, and three games win. In each game, if one side scores 2 1 point first and leads by at least 2 points, the game will win, otherwise the game will continue; If the two sides are tied at 29 and one side leads 1 point, the game will be won.

In the new competition system, every ball is scored, and players can't ask to interrupt the game except in special circumstances (such as wet floor and broken ball). However, when one side leads 1 1 in each game, 1 minute will be suspended to allow both sides to wipe sweat, drink water and have a rest.

The scorer has the right to serve. If our score is odd now, serve from the left. Now the score is even, serve from the right. In the third or only one game, when the score of one side reaches 1 1 first, the two sides exchange venues.
