What should be the standard speed of badminton, as the title Thank you

Manufacturers who regularly produce badminton balls have their own set of standards for the speed (weight) of badminton, which are generally marked on the top cover of the barrel: 76, 77, 78, 79 or 1, 2, 3, 4. A lower number indicates a slower ball speed, while a higher number indicates a faster ball speed.

Badminton weight selection in relation to temperature Ball gram 76 is used in summer high temperatures; Ball gram 77 The temperature in spring and autumn is slightly higher, and the human body feels very comfortable, and the temperature is about 25 degrees Celsius Ball gram 78 The temperature in spring and autumn is slightly lower, and the human body feels slightly cooler, and the temperature is below 18 degrees Celsius Ball gram 79 is about 5 degrees Celsius in winter This correspondence is an ideal value, and the smoked balls will be biased, for reference only.

The ball speed of badminton is measured in greens. Generally, the speed of the ball is between 76-80 greens, and the higher the number, the faster the speed. 77 is 77 Green, which is normal, and may be a little slow.

Originally, they all referred to the weight, which were 76 greens, 77 greens, and 78 greens. Green is a unit of weight when badminton is manufactured. Now the mainstream uses and 78 to mark the applicable speed of the shuttlecock.

In addition, there are two different types of ball speed markings, such as the gram used by Yonex and the gram weight mark that is still used by individual brands, for example, to represent the ball weight grams, grams and grams. Basically, the higher the number, the faster the shuttlecock will fly.

The flight of the shuttlecock is greatly affected by factors such as temperature and sea dial, so there will be different requirements for the ball speed of the shuttlecock in different seasons and altitudes.

In general, the 76 speed will be used in the summer when the temperature is high, and the temperature is lower than 25 degrees, you need a slightly higher ball speed such as 77 speed to use, and in winter or some colder areas, you can consider using a higher speed shuttlecock such as 78 speed to maintain a stable flight, if you also use 76 speed badminton will be too slow. The selection method of the other two identification methods is basically the same as that of the Green's method, the higher the temperature, the slower the ball is selected, and the lower the temperature, the faster the ball is selected. In the high sea dial area, because the air is thinner, the ball speed will be slower than that in the low sea dial area.

As for the speed of the ball selected for the international competition, it will be based on the temperature and geographical conditions at the time, choose a certain range of badminton ball speed, and then choose the player to try the ball: the ball is sent high and far outside the bottom line at one end of the court, and the landing point is the normal ball speed in the speed measurement area at the other end of the court (the speed measurement area is close to the sideline near the back service line and the bottom line, there are two small **, between these two small ** is the speed measurement area, and generally you will notice that there are two small ** there when you play the ball several times).

The fastest speed record for badminton is 322 km/h.

During the 2005 Sudirman Cup Mixed Team Badminton Tournament, the International Badminton Federation (BWF) used microwave sensors to test ball speed, and in the men's doubles match between China and Hong Kong in the group stage, Fu Haifeng hit the ball with a speed of 332 km/h, setting the fastest ball speed in a racket sport, and no one has broken this record in a real match as of June 2021.

At the World Championships in August 2010, Fu Haifeng still recorded the fastest ball speed in the tournament, and he had several kills of more than 290 km/h in the third game of the final, the fastest of which was 303 km/h, far exceeding other players.

Match scoring1. Each game adopts a best-of-three system.

2. Before the start of the match, both players will decide which side will choose whether to serve first or serve last by tossing a coin.

3. The first team to score 21 points wins the authority game.

4. If the score is 20-20, the winning side needs to surpass the opponent by 2 points to win.

5. If the score of the two sides is 29-29, the first team to score the 30th point wins.

The badminton kill speed record is held by Fu Haifeng, who reached a speed of 332 kilometers per hour in the 2011 Sudirman Cup mixed team badminton tournament, which can be called the fastest ball in a racket sport.

Badminton is the fastest ball game in ball games, with professional badminton players hitting the ball at speeds of more than 260 kilometers per hour, and the top speed can reach 300 kilometers per hour when smashing.

However, despite the speed of the shuttlecock, there are very few accidents where the shuttlecock hits a person and gets injured. This is because the weight of the shuttlecock is very light, and although the instantaneous speed is fast, it will immediately slow down when it encounters air resistance. And balls with a certain weight, such as tennis balls and baseballs, can cause serious injuries once they hit people.

The current speed of badminton can be said to be the fastest of all ball sports, and the record is also 332 kmh set by Chinese badminton doubles player Fu Haifeng in the 2005 Sudirman Cup.

Formula 1 car.

The speed of the car is about the same.

77 speed badminton, because generally 76 and 77

In the 2017 Indian Badminton Club Super League, Denmark's Kolding hit a smash that reached a speed of 264 miles (426 kilometers per hour), breaking the Guinness World Record for the fastest smash in a mile (408 kilometers) match held by Lee Chong Wei! The 408km was set by world No. 1 Lee Chong Wei at the 2015 Hong Kong Open. Lin Dan has hit 401 kilometers.

1. The maximum smash speed in badminton is 421 kilometers per hour, which was set by Malaysia's Tan Boon Hong at the Japan Open in September last year, with which he surpassed Japan's Naoki Kawamae (414 kilometers per hour).

2. Badminton sports and fitness, can not blindly pursue high speed and high smash, while exercising should pay attention to the following matters:

1 Reduce the tension (tightness) of the badminton string: The looser the string, the greater the bed effect, which can hit the ball faster and more powerfully, while transmitting less shock.

2. Choose a larger sweet spot: The so-called sweet spot is the best hitting area on the racket surface. When the point of impact is in the sweet zone, it gives you enough power, ball control, and little vibration, and you will feel comfortable.

The sweet spot of the racket is larger, and it is less likely to hit the non-sweet zone when hitting the ball, so there is less chance of vibration and less chance of injury.

3 Check the size of the racket handle: If the grip of the racket is too small, when the ball does not hit the sweet spot, the torque of the racket will be greater, and the more damage it will be to the arm. If the grip is too large, the palm of the hand will not be able to grasp the racket firmly, and it will be easy to get tired.

The appropriate size should be that there is a gap of about 5-8mm between the ring finger and the large fish muscle when holding the forehand.

4 Check the hardness of the racket: A racket with a stiff shaft requires the player to exert more force when hitting the ball, which makes the arm more tired and more prone to injury.

With a racket with a less stiff shaft, players don't need much power to hit a more powerful ball, reducing the possibility of arm fatigue. The average stiffness of badminton racket shafts has been significantly reduced compared to previous years. Of course, the softer the shaft has less control over the direction of the ball.

5 Pay attention to whether the hitting posture is correct: The incorrect hitting posture is an important cause of injury.

For example: the hitting point is too low, after the ball, not enough sideways when hitting the ball, swinging the big arm to hit the ball, etc. Consult the experts around you and correct your mistakes.

6 If the player has not been engaged in such activities for a long time (more strenuous ones), then try not to exercise vigorously during the recovery training, otherwise he will wake up the next day with soreness all over his body or some parts.

First of all, I want to correct you for a common sense mistake. The ball speed of a shuttlecock refers to the speed at which the ball flies after a person hits the ball. This is mainly determined by the technique of hitting the person's body and the racket.

You're talking about the number marked on the badminton tube, like 77This is actually the weight of the badminton, not the speed of the ball. If the weight of the badminton ball is light, the ball speed will be slow, and if the weight is heavy, the ball speed will be faster.

The badminton ball is very light, and the speed of the shuttlecock that determines the speed of the shuttlecock depends first on the weight of the shuttlecock; Secondly, the temperature of the air, the temperature of the air and the altitude of the place of play have a greater impact on its weight. Generally, in summer, the temperature is high, the humidity is high, or the altitude is high, so choose a lighter weight badminton. In winter, when the temperature is low, the climate is dry, the humidity is low, or the altitude is low, you should choose a heavier badminton.

Badminton weight selection in relation to temperature Ball gram 76 is used in summer high temperatures; The temperature is slightly higher in spring and autumn, and the body feels very comfortable, and the temperature is about 25 degrees Celsius The temperature is slightly lower in spring and autumn, and the human body feels slightly cooler, and the temperature is below 18 degrees Celsius Ball 79 is about 5 degrees Celsius in winter.

The ball speed of the badminton ball can be distinguished according to the ball head, generally the size 5 ball head is smaller, and the ball speed is faster. The No. 6 ball head is moderate, often used as a game ball, and the No. 7 ball head is relatively large and flying, stable and durable.

The speed of this shuttlecock does not need to be distinguished, its speed is as fast as it is, and there is no time when there is no distinction between them.

Badminton has to look at him when he hits. The higher the force, the faster the speed of the ball, the speed at which it starts, and the speed at which the ball is in orbit.

Generally, it is a slow ball that flies very high, and a high-speed ball that hits a straight line. Based on personal experience with curveballs in between, mid-speed balls want to have their own questions.

1. Regarding the problem of ball speed, the ball with different ball speeds is used according to the altitude and climate.

2. Badminton competitions have special regulations in this regard. In the orthopaedic bending competition, the tournament will designate 3 different ball speeds, but they must be of the same type, and the athletes designated by the referee will conduct a big test on the spot, and decide which type of badminton ball of the same type to use in each session (morning, afternoon and evening).

1. The maximum speed of badminton is fast.

2. The fastest speed of badminton can reach about 330 kilometers per hour, while the speed of tennis is about 220 kilometers per hour.

3. The badminton killing ball occurs in the confrontation, so the incoming ball must have a certain speed, according to the formula (r-1), this speed will cancel out a speed by the same amount. For example, if the speed of the incoming ball is 20 km/h, then the speed of the ball will be reduced by 20 km/h. Therefore, the speed of the ball when killing the ball is related to the situation at the time of Qing Haoyou's confrontation.

4. If the opponent passively picks the backcourt, then the speed of the incoming ball of the horizontal component will be slow, if not, the speed of the socks will be faster, and the effect of ball speed offset will be much more obvious.
