What are the rules of badminton competition?

In the singles competition, two players alternately hit the badminton on the court to prevent the ball from landing. The one who lands will lose, and the winner will get extra points. Doubles are played by four people on the court in the same way, but the doubles are very cooperative.

[Edit this paragraph] The characteristics of badminton

First, it is a whole-body exercise. Whether it is a regular badminton match or a general fitness activity, it is necessary to constantly move, jump, turn and swing on the court, and reasonably use various hitting techniques and footwork to hit the ball back and forth on the court, thus increasing the strength of upper limbs, lower limbs and waist muscles, speeding up the whole body blood circulation of exercisers and enhancing the functions of cardiovascular system and respiratory system. According to statistics, the heart rate of high-intensity badminton players can reach 160- 180 beats per minute, medium-intensity badminton players can reach 140- 150 beats per minute, and low-intensity badminton players can also reach100-/per minute. Long-term badminton can make your heart jump strongly, increase your vital capacity and improve your endurance. In addition, badminton requires practitioners to judge the ever-changing ball path in a short time and fight back decisively, so it can improve the sensitivity and coordination of the human nervous system. Second, the adjustable badminton is suitable for men, women and children, and the amount of exercise can be determined according to age, physique, sports level and the characteristics of the venue environment. Teenagers can take exercise as an effective means to promote growth and improve physical function. Exercise should be moderate, and the activity time should be 40-50 minutes. Moderate badminton can promote the height growth of teenagers and cultivate their excellent psychological qualities such as self-confidence, courage and decisiveness. The elderly and the infirm can take exercise as a method of health care and rehabilitation. The amount of exercise should be small, and the activity time should be 20-30 minutes, so as to achieve the purpose of sweating, bending over and stretching joints, thereby enhancing the functions of cardiovascular and nervous systems and preventing cardiovascular and nervous system diseases in the elderly. Children can take exercise as an active way of playing, let them run and jump in the sun, let them hit the ball, and cultivate their qualities of not being afraid of difficulties, suffering and unwilling to lag behind.

[Edit this paragraph] Badminton Competition Rules

(1) badminton court and equipment

Badminton court 1. Venue: The badminton court is rectangular, and the width of each line is 4cm. No obstacles are allowed in the range of 12m above the court and 4m around it. The clear height of the center of the court is1.524m, and the clear height of the doubles sideline is1.55m. The standard badminton court is a rectangular court, with a length of 13.40m, a width of 6. 10m for doubles and a width of 5. 18m for singles. The line width of each line on the court is 4cm, measured from the outer edge of the line. It is best to draw the boundary of the court with white, yellow or other easily recognizable colors. According to the regulations of international competitions, the minimum height of the whole stadium is 9 meters. There must be no beams or other obstacles within this height, and there must be no obstacles within 2 meters around the stadium. There must be a distance of at least 2 meters between any two parallel courses. The walls around the stadium should be dark and there should be no wind. 2.

The total length of the racket frame is no more than 68 cm, the width is no more than 23 cm, the racket face is no more than 28 cm and the width is no more than 22 cm.

(B) Introduction of badminton competition methods and main rules

1. events: men's singles, women's singles, men's doubles, women's doubles, mixed doubles, men's teams and women's teams. 2. The scoring method and rules of the new match: (1) Similar to the previous table tennis scoring method, the scoring system of 2 1 is adopted, that is, the scores of both sides reach 2 1 first, and the winner is decided in three games. After each game is tied at 20, one side leads by 2 points to win; If the two sides are tied at 29 and one side leads 1 point, the game will be won. (2) In the new competition system, every ball is scored. Except for special circumstances (such as the floor is wet and the ball is broken), players can no longer ask to interrupt the game. However, when one side leads 1 1 in each game, 1 minute will be suspended to allow both sides to wipe their sweat and drink water. (3) The scorer has the right to serve. If the scorer scores an odd number, serve from the left; Double the score and 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. (4) There are many changes in the rules of doubles, and the text is difficult to express, so it can't be mapped for the time being, so it is omitted here. 3. Scoring method for old games: (1) Unless otherwise agreed, the competition is decided by the best of three games, and the team competition adopts the best of five games system. (2) Only the server can score. (3) The player who scored 15 in doubles and men's singles won a game. (4) The player in women's singles 1 1 wins one game. When doubles and men's singles are tied for 13 or 14 (women's singles are tied for 9 or 10), score 13 or 14 (women's singles score 9 points first) ② This choice can only be made before the first appearance of the specified score and the next serve. ③ If the draw is 13 (women's singles 9), don't choose "rematch". If the draw is 14 (for women's singles, 10), those who score 14 (for women's singles, 10) can still choose "rematch". (5) After selecting "rematch", scores will be reported from "0 to 0", and the player who gets the "rematch" score first wins. ① 13 draw lots, and the first team will give 5 points. (2)14, one side will get the third point if it is tied. 39. The draw will last until one team scores 3 points first. ④ 10 draw, and the first team scored 2 points. (6) Starting from the next game, the winner of the previous game will serve first. 3. Match position: Singles: (1) When the server scores 0 or even, both players should serve or receive the service in their respective right service areas. (2) When the server scores an odd number, both players should serve or receive the service in their respective left service areas. (3) In case of "rematch", the server will determine the ranking according to the total score of the match. If the total score is 15 (odd number), both players should serve or receive from their respective left tees; If the total score is 16 (even number), both players should serve or receive the service from their respective right service courts. (4) After serving, the players of both sides are no longer restricted by the service court, and can hit any position of the opponent's court freely, and players can also stand in or outside their own court. Doubles: (1) At the beginning of the match, the winner will serve from the service court on the right. (2) Only the receiver and the receiver can receive the service; If the opponent catches the ball or is hit by it, the server scores one point. (1) The player who serves first at the beginning of each game must serve or receive the service in the correct service court when his team scores 0 or even; When the score is odd, you should serve or receive the service from the left tee. (2) The player who receives the service first at the beginning of each game must receive or serve in the correct service area when his score is 0 or even; When the score is odd, you should receive or serve in the left service area. (3) The above two completely opposite forms of standing are suitable for your partner. (3) After the local server loses the right to serve in any match, the server will serve the player first, then serve the player's companion first, then serve by one of their opponents, and then serve by another opponent, thus transferring the right to serve. (4) An athlete shall not make a mistake in serving, and shall not serve twice in the same game. (5) The player who wins a game can serve first in the next game, and the player who loses can receive the service first. (6) After serving, it is no longer restricted by the service area. Players can stand freely in their own court and hit the ball anywhere in the opponent's court. 4. Competition rules: (1) Changing venues ① Athletes should change venues under the following circumstances: 1. The first game is over. Two. The third game begins. Three. In the third game or just one game until one side reaches 1 1. (2) The athletes failed to change venues according to the above rules, and it has been found that they should change venues immediately in order to get scores. (2) legal serve: (1) When serving, neither side shall illegally delay serving. Both the server and the receiver must stand in the diagonal service area to serve and receive the service, and their feet must not touch the boundary of the service area; Part of your feet must touch the ground and you can't move before serving. The server's racket must be hit on the bearer first, and the whole ball must be lower than the server's waist. ④ At the moment of hitting the ball, the club should point downward, so that the whole rack is obviously lower than the whole grip part of the server. ⑤ After serving, the server's racket must keep swinging forward until serving. ⑥ The serve must fly upward over the net. If it is not intercepted, it should fall into the service area of the receiver. (3) Badminton violation ① It is illegal to serve. ② The server misses the ball when serving. ③ When serving, the ball hangs on the net or stops at the top of the net after passing through the net. ④ During the game: 1. The ball landed outside the sideline of the field. Two. The ball passes through the mesh or under the net. Three. The ball never crossed the net. Ⅳ. The ball hits the roof, ceiling or surrounding walls. ⅴ. The ball touches the athlete's body or clothes. ⅵ. The ball touches other people or things outside the venue (due to the structural problems of the building, the local badminton organization may formulate provisional regulations on badminton touching the building when necessary, but its national organization has the veto power). ⑤ In the game, the initial contact point of the racket or the ball is not on this side of the batter's net (after the batter hits the ball, the racket can take the ball across the net). ⑥ During the game: 1. The player's racket, body or clothes touch the net or the support of the net. Two. An athlete's racket or body intrudes into the opponent's field to any extent. Three. Obstruct an opponent, for example, from legally hitting the ball near the net. ⑦ During the competition, an athlete deliberately distracted the opponent's attention, such as shouting and posturing. 8 in the game: 1. When hitting the ball, the ball is caught or stuck on the racket and then dragged. Two. The same player swings the ball twice in a row. ⅲ. Two players from the same team hit the ball once in a row. Ⅳ. The ball hits the racket and continues to fly to the backcourt. Pet-name ruby athletes violated the rules of competition continuity. The athletes present misbehaved. (4) Serve again: ① Serve again in case of unforeseen or unexpected circumstances. ② In addition to serving, if the ball hangs on the net or stops at the top of the net, it should be served again. (3) When serving, the server and the receiver foul at the same time and should serve again. When the receiver is not ready, the server should serve again. ⑤ In the game, the ball disc is completely separated from the rest of the ball, and the service should be re-served. ⑥ When the linesman can't see the landing point of the ball clearly and the referee can't make a decision, he should serve again. ⑦ When re-serving, the last service is invalid, and the original player will serve again. (5) Dead ball: ① The ball hits the net and hangs on the net or stops at the top of the net. ② After the ball hits the net or net post, it starts to land on the hitting side. ③ The ball touches the ground. 4 "violation" or "heavy serve". (6) Service area error: ① Service order error. ② Serve from the wrong tee. Prepare to receive the service in the wrong service area, and the opponent's ball has already served. (7) Referee method of service area errors: ① If errors are found before the next service, serve again; If only one party makes a mistake and loses this round, the mistake will not be corrected. If no mistakes are found before the next serve, they will not be corrected. (3) If the service is "re-served" due to an error in the service area, the round will be invalid, and the service will be re-served after correcting the error. (4) If the service court error is not corrected, the game will continue without changing the players' new service court and new service order. (8) The sideline of the out-of-bounds singles in the competition is the in-bounds sideline. The sideline of doubles is the outermost one. The front serve line of singles is the forefront. The back serve line is the bottom line. The serve is valid between these two lines. The front serve line of doubles is the same as that of singles, and the back serve line is the line before the baseline. The serve is valid between these two lines. Badminton should have 16 feathers fixed on the ball support, and the length of the feathers is 64 mm to 70 mm, but the length of the feathers of each ball should be the same from the support surface to the tip of the feather. The top of the feather is round, the diameter is 58 mm to 68 mm, the diameter of the ball holder is 25 mm to 28 mm, and the bottom is round. The weight of badminton is 4.6 g to 5.50 g. For non-badminton, we need to make it into a skirt, and the quality and performance should not exceed 10\%. For the game ball, it must be tested before it can be used. The correct way is to stand on the end line, hit the ball forward and upward with the low hand, and the flying direction of the ball is parallel to the sideline. A qualified ball should fall between 53 and 99 cm from the opponent's end line.

(3) the responsibilities of the referee and the acceptance of complaints

The referee is fully responsible for the game. ② On-site referee presides over a game and manages the stadium and its surroundings. The referee is responsible to the referee. (3) The serve referee is responsible for judging the serve violation of the server (Rule 9). (4) The sideline referee announces that the ball is "out of bounds" or "out of bounds" on the touchline. ⑤ The on-site referee's ruling on the facts within the scope of his duties is final. ⑥ Referees should: (1) maintain and implement the rules of badminton competition, and declare "foul" or "re-serve" in time; (2) The appeal shall be determined before the next service. (3) Let athletes and spectators know the progress of the competition in time; (4) Change the line or serve the referee after consultation with the referee; 5] Make arrangements for duties that no one will perform without on-the-spot judgment; [6] When the referee can't see clearly, perform this duty or the referee "serves again"; (7) Record the information related to rule 16 and report to the presiding judge; (8) Submit all disputes related to the rules to the referee (similar complaints must be made by the player before the next serve; If it is at the end of a game, it should be put forward before leaving.

[Edit this paragraph] Badminton common terms

First of all, badminton court

[1] The badminton court is a rectangular court, with a length of 13.40m, a doubles width of 6. 10m and a singles width of 5. 18m. The center of the court is evenly divided by a net (the height of the columns on both sides is 1.55m, and the height of the net is/. Badminton court is horizontally divided into two halves by the middle line; Vertically divided into frontcourt, midfield and backcourt. The front court is the court between the front serve line and the net; Backcourt refers to the court of doubles from the end line to the back serve line; The midfield is the field between the front serve line and the back serve line of doubles.

Second, stand and hit the ball.

The position where an athlete stands on the badminton court is called a standing position. There are two kinds of stations: one is a restricted station. For example, when serving and receiving the service, the athlete must stand in the prescribed area (left half or right half) as required; The other is an unrestricted position, which can be selected according to the needs of yourself or your partner (doubles). For example, the position of singles is generally near the center line from the front serve line 1 m, and the position of doubles can be selected according to the specific tactical needs of the two doubles players. According to the above division of badminton courts, unrestricted stations can be divided into left half-court, right half-court, frontcourt, midfield and backcourt. Hitting refers to the moment when an athlete swings to hit the ball. The player standing in the left half to greet the opponent's incoming ball is called left half stroke, the right half stroke is called right half stroke, and the frontcourt, midfield and backcourt strokes are called frontcourt stroke, midfield stroke and backcourt stroke respectively. In addition, according to the height of the incoming ball, we can divide it into overhand hitting (the incoming ball is above the shoulder and the hitting point is on the shoulder) and underhand hitting (the hitting point is below the shoulder).

Third, clap your hands.

Clapping your hands is to correct the hand holding the racket. A hand that does not hold the beat refers to a hand that does not hold the beat. In badminton, we often hear terms such as forehand technique, backhand technique, forehand stroke and backhand stroke. The forehand technique refers to the technique of holding the racket on the same side; Backhand technique refers to the grip technique of different sides. For example, the technique used by right-handed players in playing right-handed ball is called forehand technique, from which technical names such as forehand serving technique and forehand hitting technique are derived. In badminton, the function of non-grip racket is mainly to hold the ball and throw the ball when serving; Used to balance the body when hitting the ball, so as to hit the ball more effectively.

Fourth, the basic route of hitting the ball

The so-called hitting line refers to the trajectory relationship between the ball in the air and the field after the player hits the ball. Badminton players cannot count the number of hitting lines. The following only studies a few basic lines that determine the rules of badminton lines. We only analyze the route name of the ball by the player hitting the ball three times with forehand. The first line from the opponent's right to the opponent's left (the line is parallel to the sideline) can be called a straight line, the second line to the opponent's right (the angle between the line and the sideline is large) can be called a diagonal line, and the third line to the opponent's midline ball (the angle between the line and the sideline is small) can be called a middle road. Similarly, the three basic hitting lines of backhand backcourt (midfield and frontcourt) can also be called this. You can combine forehand and backhand when addressing. Such as forehand straight line, forehand center line, forehand diagonal line, backhand diagonal line, etc. If you hit the ball in the middle line, you can call it this: hitting the left side of the opponent's court is a left diagonal line, hitting the right side of the opponent's court is a right diagonal line, and hitting the middle is a middle ball. When addressing badminton routes, we should pay attention to the following problems: first, we should look at where the hitting point and landing point of the ball are close, the hitting point is close to the right line and the landing point is close to the center line, all of which are forehand balls. Secondly, according to the technical names used in hitting the ball, such as backhand rubbing, it can be divided into backhand rubbing straight line and backhand rubbing the ball. In short, the basic route of badminton can be divided into five lines, namely: left straight line, middle straight line, right straight line, right diagonal line (right diagonal line) and left diagonal line (left diagonal line). According to the position of the batter's station (left, middle and right), each position can hit a straight line, a middle line and a diagonal line respectively, so nine lines can be deduced. Badminton's hitting lines are hard to describe, but there are only a few basic lines. As long as we master the rules, it will be of great benefit to our training and competition.

Verb (abbreviation for verb) racket angle and racket face direction

Racket angle refers to the angle between the racket face and the ground. The racket face direction refers to the position where the racket face faces. There are seven kinds of racket angles: racket face down, racket face down, racket face up, racket face down, racket face up, racket face down, racket face down and racket face up. The racket face direction can be divided into three types: racket face to the left, racket face to the right and racket face to the front. The control of the racket angle and racket face direction has a great influence on the hitting quality, so we must carefully adjust the racket shape and racket face in each stroke in order to hit the ball that meets the quality requirements.

Sixth, the point of attack

The so-called hitting point is the space-time position of the racket touching the ball when the player hits the ball. The hitting point includes three aspects: the first includes the height between the contact point between the racket and the ball and the ground; The second includes the front-back distance between the contact point and the body; The third includes the left and right distance from the body Choosing the right hitting point will determine the quality of hitting the ball, directly affect the strength, speed, arc and landing point of the player's hitting, and ultimately affect the player's hitting percentage, resulting in losing points or even failure. So it is very important to choose the right hitting point. Choosing the right hitting point should do the following two things: first, the judgment should be accurate, and second, the footwork should be in place (the footwork should be fast). As long as we do these two points, we can ensure that we can adjust to the most suitable position and ensure the hitting point.

[Edit this paragraph] Badminton knowledge

I always thought playing badminton rackets was the most expensive thing, but actually the ball was the most expensive thing. A YY Ti-5 racket is about 500 yuan. According to the calculation that playing badminton twice a week consumes three shuttlecocks, it takes about 12 strokes a year. Even if you play a mid-range ball for $40, it's almost $480 a year for Ti-5. As long as it is not particularly unlucky, a badminton racket can be used for at least 2-3 years, usually 5-6 years. Think about it. It's scary enough to knock out an advanced YONEX badminton racket in one year. No wonder I once read a news that an African badminton champion from Nigeria complained that the low level of badminton in Africa was because he couldn't afford enough badminton, because the training balls there cost 1 USD each, which was unbearable economically. 1. Definition of badminton in the rules of badminton competition of the International Badminton Federation: 1: The ball can be made of natural materials, artificial materials or their mixture. As long as the flying performance of the ball is similar to that of natural feathers wrapped in sheepskin and cork ball holders. 2. The ball should have 16 feathers fixed on the ball holder. Badminton Feather 3: The length of the feather is 62-70 mm, and the length of the feather of each ball from the ball support surface to the tip of the feather should be the same. 4. Feather tips are round, with a diameter of 58-68mm. 5: Feathers should be tied with thread or other suitable materials. 6: The bottom of the ball holder is spherical with a diameter of 25-28mm. 7: The ball weighs 4.74-5.50g.. 8. Ball made of non-feathers: 8. 1: skirt made of synthetic materials or ball made of natural feathers. 8.2: The bearer is as stated in Rule 6. 8.3: The size and weight of the ball shall comply with the provisions of Rules 3, 4 and 7; However, due to the difference in specific gravity and performance between synthetic materials and natural feathers, the error cannot exceed 10%. 9: As long as the general style, speed and flight performance of the ball remain unchanged, with the approval of the relevant organizations, the standard ball may not be used in the following special circumstances. 9. 1: When the standard ball is not suitable due to the weather conditions at altitude; 9.2: Only when the change is beneficial to competition. Badminton 2. Classification of badminton hair: high-quality badminton hair must use goose knife hair. If you use duck knife hair and other hair pieces, its quality is difficult to guarantee. The classification of ball hair is very complicated. Because there is no unified national classification and numbering standard at present, the labels of badminton produced by various manufacturers are all customized. If different manufacturers have products with the same label, it doesn't mean that their quality is the same. Take Jinhe Factory as an example: all middle and high-grade badminton, that is, products with the word "A", are made of live plucked white goose feathers. First, it is divided into large, medium and small hairs according to the hair quality, then it is divided into one, two, three and four grades according to the hair quality, then it is divided into five standards according to the warp of the hair, and then it is classified according to the thickness of the hair stalk and the thickness of the hair. The 16 feathers used in the same badminton must be of the same category and as similar as possible. The more high-end products are used, the more consistent the 16 wig is, so as to ensure the flying quality of the products. Low-grade products, that is, ordinary leisure balls, are also made of white goose nest hair and camel hair, and the processing technology is the same as that of high-grade products, ensuring aesthetics and durability. 3. Classification of badminton ball heads: According to the materials used, there are three common types: hard plastic, foamed plastic and cork. The first two kinds are mainly used for low-grade leisure badminton with low cost and poor performance. Middle and high-grade badminton all adopt natural cork ball heads, which can be roughly divided into three categories: integral cork ball heads, composite cork ball heads and recycled cork ball heads. Their structural drawings are as follows: It can be seen that the best ball head is of course made of integral natural cork, and the ball head made by composite method is low in cost and not easy to break, but if the hitting force is large, it is easy to break the lower part of recycled cork, thus affecting the hitting performance. However, the cost of recycled cork ball head is lower, and the flying performance is better than that of non-cork ball head. Although its anti-strike ability is poor, it can meet the needs of specific users. For example, the 204A produced by Jinhe Factory is a low-priced medium-performance badminton suitable for beginners. Considering that beginners' hitting power is generally not too great, the main reason for badminton damage is that it is easy to hit the ball hair, so the regenerated cork ball head is not easy to crack, and its flying performance can fully meet the practice. Of course, the strength of cork ball heads recycled by different manufacturers sometimes varies greatly due to different production processes. In recent years, the ball head manufacturer has developed a ball head made of bionic plastic and natural cork, which is cheap and good, and the effect is ideal. 4. Identification of badminton Mao Mao quality: The feathers of high-quality badminton must be high-quality goose feathers. The strength and toughness of goose feather are especially suitable for badminton, but its cost is high and the supply of raw materials is limited, so some badminton manufacturers with low requirements use duck feather. It is difficult to distinguish duck feathers from goose feathers only by appearance, and the well-made duck feather badminton has good flight performance. Because the hair stems of the two hair pieces are different, their hitting resistance is much worse than that of goose feather badminton, and normal hitting is easy to break because of the price of duck feather. 5. Difference of badminton glue: The quality of glue directly affects the firmness and durability of badminton. Badminton glue can be divided into two categories: advanced resin glue and chemical glue. High-grade resin adhesive is superior to chemical adhesive in hardness and firmness, but its cost is relatively high, and it is generally used to make high-grade badminton. For example, 200A and 20 1A badminton made by Jinhe Factory are high-grade resin glue, while other kinds of badminton are high-strength chemical glue. In order to ensure the quality, the glue content of each badminton is higher than the requirements of national standards. 6. Finished badminton quality inspection items: inspection items generally include: stability, beating resistance, weight, caliber, speed, adhesion fastness, hook fastness, etc. The manufacturers of these items generally do not and do not need to test them one by one. When consumers buy badminton, they can test and compare their most concerned qualities according to the above items. 7. The difference between high-end products and low-end products: The main difference except appearance lies in the flight performance of badminton, that is, stability, speed, deformation when being hit, and rotation when flying. High-grade badminton requires a lot of wigs, and 16 wigs on a ball require almost the same appearance and quality, so as to ensure the high standard requirements of badminton, which leads to its higher price. 8. The relationship between badminton speed, weight and caliber: The flying speed of badminton in the same area mainly depends on its overall weight, caliber, hair quality, the difference between left and right hair, and the weight ratio of the ball head to the ball body. Generally speaking, the caliber of badminton produced by the same factory is fixed. For example, the standard of badminton caliber of Golden Eagle brand is: 66.5mm±0.5mm, that is, between 66 and 67 mm. At this time, the main factors that determine the ball speed are the overall weight of the ball and the weight ratio of the ball head to the ball body. We have strict standards to control the weight ratio of the ball head to the ball body to ensure the flight performance of badminton. So according to the overall weight of the ball, we can know its approximate flying speed and where it is suitable. 9. What kind of badminton should I choose in different altitude climate areas? The most basic requirement of badminton is that the speed or weight of the ball used must be appropriate, otherwise many techniques will be difficult to play. Badminton with the same weight will fly at different speeds in different areas, because the weight of the ball is closely related to altitude and climate. The high air density at high altitude will reduce the air resistance when badminton flies, so the weight of badminton used at high altitude will be reduced. At low altitude, the air density is high, and the air resistance of badminton in flight is great, so the weight of badminton used at low altitude is heavier. Take the golden eagle products as an example: Shanghai: 5.2g, Guangzhou: 5. 1g, Kunming: 4.7g, Chengdu: 4.9g. In addition, the air humidity and temperature also have certain influence on the speed of badminton, but the altitude has the most obvious influence. 10. What are the disadvantages of using heavy badminton or light badminton to the racket and human body? The overall weight of badminton is too heavy or the ball head is too heavy, which will cause great vibration when hitting the ball, which will have a great impact on the badminton racket and badminton line and reduce the service life of the badminton racket and badminton line. The most obvious thing is that the service life of badminton line will be greatly shortened. On the other hand, long-term vibration will be transmitted to the batter's arm, which will also have some bad effects on the arm. If the weight of badminton is too light, because the ball is not in place, the batter will send out more strength to achieve the goal of hitting the ball in place, which will easily cause fatigue and injury to the arm. So choosing the right weight badminton can not only make you enjoy badminton better, but also reduce your risk of injury. 1 1. What's the manufacturing process of badminton? The production technology of badminton is divided into three parts: wool making, head making and combination. Wool making process: wool washing, drying, wool selection, wool washing, classification, warping and wool mixing. Head making process: grinding, repairing, wrapping, baking, peeling, drilling and weighing. Combined technology: hair planting, glue injection and drying, thread hooking, adjustment, glue brushing and drying, head wiping, edge winding, weighing, applique, finishing, stability testing, weighing, packaging and warehousing.
