(1) badminton court and equipment 1. Venue: The badminton court is rectangular, as shown in the figure. The width of each line is 4 cm, and there must be no obstacles within 12 meters above the court and within 4 meters around it. The clear height of the center of the court is1.524m, and the clear height of the sideline of doubles is1.55m. 2. The weight of the equipment ball is 4.74g ~ 5.5g, and 16 feathers are inserted on the hemispherical cork plug. 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. (2) 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 265,438+0 is adopted, that is, the scores of both sides reach 265,438+0 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. Cancel the serve line in the back row (singles). 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 best-of-three game system is adopted in the competition and the best-of-five game system is adopted in the team competition; (2) Only the server can score; (3) The player who scored 65,438+05 points in doubles and men's singles won a game. (4) The player in women's singles 1 1 wins one game. (1) When doubles and men's singles draw 13 or 14 (women's singles draw 9 to 10), score 13 or 14 (women's singles score 9 or 65438) ② This option can only be scored in the specified way. 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". [6] After selecting "rematch", scores will be reported from "0 to 0", and the player who gets the "rematch" score first wins the game. 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. Once in the next game, the winner of the last game serves first. 3. Stand in the game: Singles: (1) When the server scores 0 or even, the players of both sides 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 from their respective left service areas. ⑶ In the "rematch", the server decides 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, players from both sides are free to hit any position in the other side's court, which is not limited by the service area, and players can also stand in their own court or outside the court. Doubles: (1) At the beginning of the match, the winner should serve from the right service court. (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. (4) After the local server loses the right to serve in any match, the server serves first, then the server's partner, then one of their opponents, and then another opponent serves, thus transferring the right to serve. 5] Players are not allowed to miss the serve or serve twice in the same game. [6] Any player who wins a game can serve first in the next game, and any player who loses can receive the service first. Once you serve, you are no longer restricted by the tee. Athletes can stand freely in their own field and hit the ball anywhere on the field. 4. Rules of the game: (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.

(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 During the match, the ball disc is completely separated from other parts 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 touches 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. 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. Commonly used badminton terms-. The center of the field is a rectangular field evenly divided by the net (the height of the columns on both sides is 1.55 m, and the height of the net in the middle is 1.524 m) (see the attached drawing of the competition rules for details). 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, the position and the position where the batter stands on the badminton court is called the 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 meter, 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). Clapping and not clapping refers to 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 line of hitting the ball The so-called hitting line refers to the relationship between the trajectory of the ball running in the air after being hit by an athlete and the venue. 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 one's right to the other's left (which is parallel to the sideline) can be called a straight line, the second line to the other's right (which has a large angle with the sideline) can be called a diagonal line, and the third line to the other's center line has a small angle with the sideline) 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: the left side of the opponent's court is a left diagonal line, the right side of the opponent's court is a right diagonal line, and the middle ball is a middle ball. The following questions should be answered in the name of badminton route: First of all, 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. V. racket angle and racket face direction racket angle refers to the angle formed by 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 hitting point The so-called hitting point is the time and space position where the racket touches 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 be done: first, the judgment should be accurate, and the second step should be in place (the pace 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.
