1870 A.D. The Duke of Beaufort of badmenton manor in Gloucestershire, England, received British officers returning from India on holiday in his manor. These officers played games in the hall when the weather was too bad to go out. This kind of game is the predecessor of badminton today. It didn't start with a name, but was called the game at badminton. Badminton was a shuttlecock at that time. The tennis racket was used as a shuttlecock board. After that, the shuttlecock board and shuttlecock were gradually improved and became today's badminton sport. To commemorate the origin of badminton in burmington village, people took badminton manor as the official name of badminton.
The standard badminton court is rectangular with a length of 13.4 The width of the singles court is 5.18 meters, and the width of the doubles court is 6.1 meters. The two sidelines outside the court are the doubles field sidelines, and the inside two sidelines are the singles field sidelines. The doubles sidelines and singles sidelines are drawn with a 0.04 meter wide white line (also can be pasted directly with 0.04 meter adhesive tape). The two lines which are 1.98 meters away from the net and parallel to each other are the front service line, the two lines 0.76 meters away from the end line and parallel to the end line are the back service line, and the one connecting the middle point of the front service line and the middle point of the end line is the middle line, which divides the court into left and right service areas. The height above the court is more than 12 meters (minimum 9 meters), and there are no obstacles within 2 meters around the court. In addition, it is necessary to mark the test ball speed area at 53 cm ~ 57 cm and 95 cm ~ 99 cm away from the outer edge of the end line.
1、 Basic techniques of badminton
（1） Grip of badminton racket
Forehand grip: before holding the racket, hold the racket with your left hand to make the racket face vertical to the ground. Then open your right hand so that the lower part of the palm is against the bottom of the racket grip, and the mouth of the tiger is facing the racket frame. The little finger, ring finger and middle finger naturally close together, index finger and middle finger slightly separate, naturally bend and stick on the handle.
1.1 forehand rubbing grip: on the basis of forehand grip The thumb, index finger, middle finger and ring finger are slightly loosened to make the handle leave the palm. The thumb is obliquely attached to the upper edge of the inner side of the racket handle, and the index finger is slightly extended forward, so that the second finger band is obliquely attached to the wide surface outside the clapper handle.
1.2 forehand hook diagonal grip: Based on forehand grip The second knuckle of the index finger and the base of the other three fingers are pasted on the wide surface outside the handle, while the handle is not attached to the palm.
Backhand grip: the backhand is a forehand grip, which turns the racket frame outward (i.e. to the left), the inner front part of the thumb is pasted on the narrow side of the racket handle, and the index finger is close to the middle finger, ring finger and little finger. Usually, there is a certain amount of strength between the grip and the hand grip, which is beneficial to grip the wrist with a certain amount of strength.
2.1 backhand rubbing grip: on the basis of forehand grip The thumb, index finger, middle finger and ring finger are slightly loosened, and the racket handle leaves the palm and turns the racket inward at the same time. The thumb is pasted on the upper edge of the inner side of the racket handle, and the third joint of the index finger is attached to the lower small edge outside the racket handle.
2.2 backhand diagonal grip: Based on forehand grip In the upper part, the thumb, index finger, middle finger and ring finger are slightly loosened, and the clapper handle is moved away from the palm. At the same time, the racking handle is rotated inward. The inner side of the second thumb joint is pasted on the upper small edge of the racket handle, the second finger joint of the index finger is attached to the lower middle wide surface of the clapper handle, and the other three fingers naturally grasp on the lower middle wide surface and the wide surface inside the clapper handle.
For grip grip, we don't have to grasp it. No matter what kind of grip, the ultimate goal is to make our wrists more flexible and fingers can give full play to their strength. But there is one thing: the grip method can not limit or affect the activity of the wrist or affect the force of the fingers; otherwise, the grip is wrong and should be corrected as soon as possible. Once it is finalized, it will not be easy to change it.
（2） Badminton serve technique
Service technology can be divided into forehand and backhand. Generally speaking, forehand service can be used in front of the net, fast ball, high ball and long ball.
1 serve high and far ball: the so-called high and far ball is to send the ball high and far, so that the ball flies to the top of the opponent's backcourt. The angle between the ball's flight route and the ground should be greater than 45 ° so that the ball can fall vertically near the baseline of the opponent's field.
2. Forehand flat lob: the posture and action are the same as those of forehand high and far shots, but the direction of force and the hitting point are different. When the ball is high and flat, the parabola of the ball is not big, which makes the ball quickly cross the air of the opponent's field area and fall near the baseline. The pitch angle formed by the line of the ball in the air and the ground is about 45 degrees.
Forehand forehand serve: the forehand serve is to serve the ball near the front service line in the opponent's service area. When the racket touches the ball, the racket face cuts the ball from right to left to make the ball just cross the net and fall near the opponent's front service line.
Backhand forehand service: backhand forehand service is to use backhand service technology to send the ball near the front service line in the opponent's service area. When hitting the ball, the racket pushes the ball forward from back to front. The highest point of the ball's running curve is slightly higher than the top of the net. When the racket touches the ball, the racket will hit the ball in a cutting manner to make the ball fall near the front service line of the opponent's court.
Backhand flat fastball: the backhand flat fastball is the same as the forehand's. When the racket hits the ball in the same direction as the back of the net, the angle of the shot is the same as that of the forehand.
（3） Position and posture of receiving service
The position of singles is usually 1.5 meters away from the service line. Stand in the right service area near the center line, and in the middle of the left service area. The main purpose of this stance is to guard against the opponent's direct attack on the backhand. Generally, the left foot is in front and the right foot is in the back. The legs are slightly bent. The abdomen contains the chest. The body center of gravity is placed on the front foot, and the heel of the back foot is slightly raised. Body half side of the net, racket in front of the body, eyes on each other.
（4） Footwork on badminton court
1 start: from the center of the position ready to catch the ball to start to hit the position, known as starting. A game starts hundreds of times (basically one shot per return). In order to start fast, we must be quick in reaction, accurate in judgment and correct in preparation for starting. There are two kinds of preparation postures. One is the receiving position (standing in place according to the rules), with the left foot in front and the right foot in the back,
Flexible choice of itinerary, scenic spots and departure time
The other is the preparation posture of the two sides in the process of the fight, which should be the right foot in front of the ground, the left foot on the ground, the heel lifted, the knee slightly bent, the upper body slightly tilted forward, the center of gravity fell between the two feet, holding the racket in front of the abdomen , the whole posture should be coordinated and relaxed, and the starting posture should be maintained
2 movement: mainly refers to the moving method from the center position to the hitting position. The basic footwork of moving includes cushion step, cross step, small broken step, parallel step, pedal turn step, step and jump step. Using these methods, the combined footwork of hitting ball from the central position to different positions in the field area is composed of backward footwork, bilateral moving footwork and net footwork Corning company 。 The number of steps from the central position to the hitting point is generally one step, two steps or three steps, which must be determined according to the distance from the ball to the body at that time. The number of steps, the speed of stride frequency and the size of stride length affect the speed of moving. The basic steps of various movements are introduced below:
L step: when the right (left) foot takes a step forward (backward), the back heel enters, and then takes another step in the same direction with the same foot as the cushion step. The cushion step is generally used for adjusting the step distance.
L cross step: the left and right feet alternately move forward, to the side or backward for cross step. The one who passes through the front of the other foot is the front cross step, and the one passing behind the other foot is the back cross step. The cross step usually retreats more in the backcourt.
Small steps: those moving in small cross steps are called small broken steps. Because of the small stride and fast stride frequency, it is usually used when starting or reversing.
L joint step: when the right foot moves forward (or backward), the left foot immediately takes a step to the right heel, and then the right foot moves forward (backward) for another step, which is called parallel step.
Lunge: take one foot as the axis and the other foot for backward or forward pedaling.
L step: in the last step of the movement, when the left foot pushes backward, the right foot takes a big step towards the direction of the ball, which is called pedaling step. It is mostly used for hitting the net, and it is often used when moving the two corners of the baseline in the backcourt.
L jump step: the footwork of taking off and flying to hit the ball is jumping step. It can be divided into two kinds: one is to jump with the leading foot (or both feet) when attacking the net or moving to both sides to kill the ball; the other is to kill the ball when the opponent hits the high and far ball with his right foot (or both feet) when he jumps to the highest point.
3 Return (return to the center position) after hitting the ball, try to keep (or recover) the body balance as soon as possible, and immediately move to the center position, so as to be ready to meet the next ball in the center position, which is called swing back. Beginners often lack the consciousness of "returning to the center" and stop where they have finished playing, which must be corrected. Of course, with the accumulation of experience in competition. It is gradually realized that it is not always necessary to return to the center every time a ball is hit, but to choose the most reasonable return route and position according to the actual situation of the game and the technical and tactical characteristics of both sides.
（5） Badminton backcourt hitting technique
The high ball is one of the backcourt hitting techniques. The high ball is divided into high and far balls and high balls. Hitting the high and far ball is to hit the ball high and far. The ball flying to the opponent's bottom line is developed from the high and far ball. Its flying speed is faster than that of the high and far ball, and the curve is lower than the high and far ball. It is one of the effective techniques of the back court attack. Hitting high ball can be divided into forehand, overhead, backhand hit straight line and diagonal high ball.
1 forehand straight and diagonal lobs
After take-off, the wrist controls the racket to aim at the ball path, quickly swings the racket to hit the back of the ball, the ball flies along a straight line; if the wrist controls the racket surface to hit the bottom right of the ball holder, the ball flies along the diagonal direction. After hitting the ball, the arm naturally recovers to the chest with the inertia.
2 overhead straight and diagonal lobs
If the ball from the other side flies to the back court area, the hitting point should be located in the front of the head. Swing the whip to the back of the ball to make the ball fly over the net in a straight line.
When hitting a diagonal high ball on the head, the clapping method is slightly different. Use thumb and index finger to twist the racket handle to the left to make the mouth of the racket aim at the small edge outside the racket. The racket still bypasses the top of the head from the right back, and the forearm rotates inward to drive the wrist to receive the force, forming a whip to hit the left rear of the ball holder. After hitting the ball, the inner rotation of the forearm is more obvious, the inertia effect is greater, and the arm swings forward naturally.
3. Backhand high shot
If the opponent's ball to the left back field area, quickly turn the body to the rear, move to the appropriate position, back to the net, backhand grip the racket, hit the ball back and up.
4 drop ball
If the opponent hits a lob, the opponent can hit, cut, and chop from the backcourt to the opponent's near net. This is called drop shot. According to the movement method, the flying curve of the ball can be divided into light lifting, blocking hanging and splitting hanging; according to the position of the hand and the position of the ball falling, it can be divided into three types: light lifting, blocking hanging and splitting hanging
4.1 forehand straight and diagonal balls
When hanging a straight-line ball, the direction of hitting force is forward and downward, but at the moment of hitting, the forearm suddenly decelerates, and gently cuts the right rear lower part of the ball holder with the flashing of wrist, so that the ball falls after crossing the net; when hanging the diagonal ball, the direction of hitting force is diagonal downward.
4.2 overhead linear ball and overhead diagonal ball
The hitting action is almost similar to that of a straight high ball on the top of the head, except that at the moment of hitting, the forearm suddenly rotates inward and swings forward and downward. The extension and extension of the wrist drives the racket to lightly touch the left rear lower part of the ball holder, and the ball flies in a straight line.
4.3 backhand hanging linear ball and backhand diagonal ball
The action before hitting the ball with the backhand hanging straight ball and the backhand hanging diagonal ball is similar to that of the backhand hitting the high ball. The difference is that the forearm should be swung up, with the inside of the thumb against the racket handle, and the wrist "swings the wrist" backward to gently hit the back and bottom part of the ball holder, so that the flight direction of the ball falls in front of the opponent's net in a straight and diagonal direction.
5 kill the ball
5.1 overhead smash
The preparation posture of overhead smash is similar to that of overhead smash. The difference is that when hitting the ball, the waist and abdomen should be used to drive the big arm, coordinate the comprehensive strength of the forearm and wrist to form a whipping action. The angle between the racket surface and the horizontal plane is less than 90 degrees. The action method of overhead smashing diagonal line is basically the same as that of overhead smashing. Only when hitting the ball, do your best to hit the ball in the diagonal direction that 's ok.
5.2 backhand smash
The preparation action of backhand smash is the same as backhand hitting high ball. The difference is that the swing force before hitting the ball should be large. After jumping up, the body's back bow, the extension of arm and wrist, and the whipping force of abduction can exert force to the opponent's straight line or diagonal line. The horizontal angle between the racket and the smashing direction should be less than 90 degrees at the moment of hitting.
5.3 smashing in the air
In addition to the above three smashing techniques, there is also a smash which is often used in the game, that is, the flying assault smash technology. When the opponent hits a flat ball with a low arc, his body will soar, his upper body will fall back into a reverse bow, and his shoulder will be pulled back as far as possible. When hitting, the forearm will be quickly raised, and the wrist will be stretched from the back to the pronation, and the forearm will be bent and squeezed to hit the ball forward and down at high speed.
（6） Badminton midfield hitting technique
Forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand forehand fore. Hold the racket and get ready to catch the ball. Push the ball forward from the top of the net.
The other is the forearm rotation to adduction, driving the racket from the right to the front of the straight line net. After hitting the ball, turn left to face the net, and then step forward with the right foot. The racket turns left with the body and draws in front of the body
1.1 forehand block in front of diagonal net: when swinging When the elbow joint bends and retracts, the forearm slightly rotates, and the wrist flashes from the back to the right side of the ball holder. The hitting point is in front of the right side. The wrist and fingers control the angle of the racket surface to make the ball fall to the diagonal net
1.2 backhand catch in front of the straight line net
Move to the side line of the left field area with the footwork of catching and killing the ball, turn left and lean forward, face the net with the right shoulder, abduct the wrist, and lead the racket to the front and upper part of the left shoulder. When hitting the ball, take advantage of the impact of the ball from the other side, drive the racket with the forearm from the top left to the front left with the top force of the thumb, and lightly hit the ball holder to block the ball back to the front of the straight net. After hitting the ball, the body turns right to face the net, and the racket moves in front of the body.
2.1 backhand catch hook in front of diagonal net: press the hook with backhand Diagonal grip. When hitting the ball, the wrist moves from abduction to outstretching, and the left lower part of the ball holder is swung to make the ball fly diagonally.
2.2 forehand pick straight backcourt lob: right arm before hitting Pull back slightly to the right, rotate the forearm outward, extend the wrist as far as possible, and hold the racket at the back of the body. When hitting the ball, the forearm rotates inward, and the wrist flashes from the back to the back of the wrist. After hitting the ball, the forearm rotates inward, and the racket swings in front of the body and then recovers to the front of the body.
2.3 backhand volley: before hitting The forearm is rotated inward, the wrist is abducted, and the lead is to the left side. When the opponent kills the left line ball, quickly move to the front of the ball, support the big arm, swing the small arm to the right front rapidly, the wrist flashes from abduction to extension, hold the racket tightly, and with the jacking force of thumb, swing the ball at full speed to make the ball fly in a straight line. If you swing diagonally, the ball flies diagonally.
3. Dribble technique
3.1 forehand drive: standing in the middle of the right field Stand with two feet parallel, slightly wider than the shoulder, center of gravity between the two feet, slightly bend the knee to close the abdomen, and hold the forehand to hold the clap in front of the right shoulder. Before hitting the ball, the elbow joint is swinging forward, the forearm is slightly backward with external rotation, the wrist is slightly extended to the extension, and the racket is drawn to the back of the body. With a high-speed grip, swing the ball forward and back with your right hand. Take a step back to the center of the left foot and swing the ball back to the left.
3.2 backhand drive: cross the right foot in front of the left The center of gravity is on the left foot, and the right hand backhand grip is in front of the left side. When hitting the ball, raise the elbow slightly, rotate the forearm inward, abduct the wrist, and lead the racket to the left side. When hitting the ball, under the right turn of the hip, the forearm rotates outwards, and the wrist moves from abduction to straight flash, and swings to hit the bottom of the ball holder. After hitting the ball, the racket moves back to the right side with the body moving back. Corning fiber 。 The common mistakes in flat stroke are as follows: the body center of gravity is unstable, which affects the hitting action of the arm; the hitting time is not accurate; when hitting the ball, the forearm drives the wrist, and the finger whips forward, which affects the explosive force.
3.3 forehand draw 〔 quick play 〕: separate feet With the right foot slightly forward and the left foot at the back, bend the knees into a half squat position, hold the racket in the front (from the mouth of the tiger to the wide side), and lift the racket with the racket face over the top of the head. When judging that the ball is over the head, move forward slightly, and take a small step forward with the left foot, and slightly straighten the right foot. Form a left lunge, and select the hitting point at the top of the right shoulder. Pick up the upper arm forward and upward, bend the elbow, swing the forearm with external rotation, and lead the racket behind the head. When hitting the ball, the forearm is forward, the wrist is extended from back to forward flexion, and the swing slaps the back of the ball holder, so that the ball flies straight and quickly near the middle field area of the opponent. After hitting, the racket covers the front with the potential, and the right foot takes a step forward to the left, standing slightly backward on both sides of the middle line. The racket is lifted back from the left bottom to the upper front to prepare for the second incoming ball.
3: parallel backhand on the left Area, center of gravity in the right foot, lift in front of the right side. To the left side of the court, swing the ball forward and backward with the left arm, and turn the ball to the left side. When hitting the ball, the forearm rotates outward, the wrist is straight and flashing, and the fingers suddenly grasp the handle and cover the back of the ball to make the ball fly forward relatively smoothly.
（7） Badminton front court hitting technique
Front court techniques include putting, rubbing, pushing, hooking, throwing and picking in front of the net. Among them, rubbing, pushing, hooking and throwing are offensive techniques, which require consistency in the early stage of hitting, and sudden changes occur in the moment of hitting; the racket should be flexible, the movements should be delicate, and the wrists and fingers should be dexterous, so as to control the landing point of the ball. The threat of hitting the ball in the front court is great. Because the ball flies short and lands fast, it often makes the opponent unprepared and scores directly. Even if you can't score directly, you can force the opponent to return the ball passively and create a chance for the next shot. If the net forward attack and the attack in the middle and back field are combined closely, the continuous attack of the front and back fields can be exerted and the initiative can be mastered.
1 ball before putting the net:
1.1 forehand in front of the net: when the opponent hits the ball to himself When in front of the forehand net, use the forehand grip method to gently cut and hold the racket to bounce the ball up and just as soon as it passes the net, it will fall downward. The general action is: move sideways to the direction of the ball, lean forward slightly, and hold the racket in front of the body with the right hand. The last step of footwork movement is the right foot towards the ball. Take a long lunge, raise your body center of gravity, reach your forearm to the ball, lift it up and up, and lean to the net. Strive for high click ball, grip Bo relax, slightly close wrist, oblique to the ball or rub cut. In the process of hitting the ball, the left hand should be raised flat backward to coordinate the movement. The strength, speed and angle of the racket mainly depend on the distance from the net and the speed of the ball. If the ball is far away from the net, and the speed is faster, the power of putting the ball should be greater, otherwise, the power should be smaller. After the net is released, the body returns to the ready position.
1.2 backhand putting the ball in front of the net: the action essentials before hitting the ball are the same Put the ball in front of the net, just in the opposite direction. When hitting the ball, it mainly relies on the combined force of forearm extension, external rotation and wrist retraction to abduct, and lightly support the bottom to easily cross the net. After hitting the ball, the whole action is restored to the preparation position for the next stroke.
2 net before the ball
2.1 forehand net rubbing: before hitting When hitting the ball, speed up the swing speed on the basis of the forehand putting the ball in front of the net, and rub the lower right part of the ball to make the ball rotate and roll over the net.
2.2 before hitting the backhand net The forearm is stretched forward and rotated outward, and the wrist is retracted to abduction; the right rear bottom of the ball is rubbed to make the ball roll over the net. In addition, the forearm can be slightly straightened, the wrist from abduction to adduction, driving the racket forward cutting, hitting the back bottom of the ball holder, so that the ball rotates downward through the net.
3.1 forehand push in a straight line: stand in front of the net, when the ball comes over, The racket is raised to the right. When the elbow joint is slightly flexed and recovered, the forearm rotates slightly, the wrist extends later, and the racket swings back slightly to the right with the racket face facing the ball. Release the little finger and ring finger slightly, so that the handle is slightly away from the thenar muscle of the palm. The thumb and index finger slightly twist the racket handle outward, and the racking face is more backward. Push the back of the ball holder to make the ball fly in a straight line.
3.2 forehand diagonal push: preparation for diagonal push technique The posture and the action before hitting the ball are the same as pushing the straight line, but when hitting the ball, the hitting point is in front of the right shoulder. Push the right rear of the ball holder to make the ball fly along the diagonal direction. At this time, the wrist should control the angle of the racket face, and the arm should not be fully extended when flashing the wrist.
3.3: high backhand in the net With the backhand grip method, the ball with a flat arc and faster speed is hit to the opponent's baseline with the backhand grip method. When the forearm is extended slightly, the wrist is extended from abduction to flashing wrist. The middle finger, ring finger and little finger suddenly grip the racket handle, thumb presses the racket, swings forward, and pushes the left side of the ball holder.
3.4 backhand push diagonal: backhand push diagonal stroke It is basically the same as pushing a straight line. The difference is that the bat should be swung to the right and forward at the moment of hitting. Push the left rear of the ball to make the ball fly along the diagonal direction.
. 4.1 hook the diagonal ball in front of forehand net: hook ball is generally used Step and step on the Internet. As the footwork moves, the racket is lifted up to the right with the forearm. When the forearm is stretched forward, it slightly turns out. The wrist slightly extends back, and the grip of the racket changes slightly. Twist the handle of the cypress out slightly to make the thumb stick to the wide surface of the handle, and the second knuckle of the index finger is pasted on the opposite wide surface, and the handle does not touch the palm. When hitting the ball, slightly inside the forearm is pulled to the left, and the wrist is extended from later to inward. The racket pulls the right lower part of the ball holder, and the angle of the racket surface is controlled by the wrist and fingers. After hitting, the racket is recovered to the chest
4.2 the diagonal ball in front of backhand net: moving with footwork At the same time, the arm to the left front flat (note that the arm does not extend straight, slightly bent can). When hitting the ball, with the elbow sinking, forearm recovery and external rotation, at the same time, the index finger and thumb twist the racket handle to make the racket face pull the left rear of the ball holder, and fly the ball diagonally across the net. After hitting the ball, the racket is recovered to the chest to make active preparation for the next ball.
5 smash ball:
When the ball is on the top of the net, it is a kind of technical action that can press the ball on the net with the fastest speed. The attack can be divided into forehand attack and backhand attack. Its route is wired, and it is a threat technology in front of the net. The key to catching the ball is "fast". First of all, it depends on the quick judgment. Once the judgment is made, it is required to start fast and use the step or jump step to get on the net, and at the same time, to seize the opportunity of the ball at the top of the net to shoot, so as to solve the battle in one fell swoop.
5.1 in front of the net: the body jumps up in the air or the right foot pedals across At the same time, the forearm is raised forward and up, and the racket is facing the ball. When hitting the ball. With the arm from flexion to extension, wrist from back to forward flash and finger pressure, the ball will be thrown down. The wrist is the key to control the strength. The swing distance is short, the action is small, and the explosive force is strong. Only when the ball is attacked can it have a certain threat. If the ball is close to the top of the net, the "sliding" method is adopted, and the ball is touched and pressed down from the left by the wrist, so as to avoid the racket's foul. After the ball, pay attention to the leg buffer, control the center of gravity, so as not to touch the net.
5.2 backhand net smash: backhand grip Hold in front of the left side. When the body jumps up and strides onto the net, the racket is raised with the forearm extended forward, the wrist is slightly bent, the thumb is pressed on the wide surface of the racket handle, and the other four fingers naturally close together, and the racket face is facing the ball. When hitting the ball, the arm should be bent to extend, the wrist should be slightly bent to the back, and the thumb should be pressed to accelerate the swing. After hitting, the racket should be recovered to the front of the body with the arm.
6 pick the ball
6.1 forehand net pick
The preparation is the same as the forehand release. Reach the ball as far forward as you can. When hitting the ball, swing from the bottom to the right and forward to the top left. On this basis, if the racket swings forward to the right, it will pick out a straight lob; if the racket swings forward to the left, it will pick out a diagonal lob.
6.2 backhand net forward pick
The preparation position is the same as the backhand net. Before hitting the ball, pull back the right arm to lift the elbow and lead the racket. When hitting the ball, the forearm fully rotates, and the wrist flashes from flexion to extension. If the racket is swung from the bottom left to the front and up, the ball will fly in a straight line; if the racket is swung from the bottom left to the front and up to the front, the ball will fly diagonally.
2、 Brief introduction of badminton tactics
There is a close relationship between tactics and tactics. In actual combat, tactics are determined according to the playing methods of both sides and the specific situation on the field. The principle of "attacking the other with one's own strengths" is the principle
（1） Singles tactics
1 serve and rush attack tactics: from the first stroke of service, strive to control the opponent and score with attack and kill. This kind of tactics, generally for the net before the low ball, flat fast ball, flat high ball, strive for the third racket initiative attack. This kind of tactics is used to deal with the opponent with poor adaptability, or at the critical moment of the game, Optical fiber jumper manufacturing equipment 。 The effect is often good. In the implementation of this tactic, high quality service should be guaranteed, otherwise it is difficult to succeed.
2 attack backcourt tactics: this tactic is to hit the high ball and repeatedly press the two corners of the opponent's baseline to cause the opponent's passivity, and then look for opportunities to attack. It is very effective to use it to deal with beginners, or the backcourt counter attack ability is poor, or the backward step is slow and eager to get online opponents.
3 attack front court tactics: for the opponent with poor technique in front of the net, this tactic can be used to attract the opponent to the front of the net first, and then attack the back court. In order to use this tactic, we should first have a good shot technique in front of the net.
4 play square ball tactics: if the opponent's pace is slow, physical strength is poor, and the technology is not comprehensive, you can quickly and accurately attack the four corners of the opponent's field area, and look for opportunities to attack the empty space. The main purpose of this tactic is to force the opponent to run back and forth, passively deal with it, and attack it when the quality of the return ball decreases or the flaws appear.
5. Kill and hang the net tactics: for the backcourt lob played by the opponent, our side first uses the kill ball and the drop ball to press the ball down, and the landing point is near the two sidelines in the field area, resulting in the opponent's passive return of the ball. If the opponent returns to the net, his side quickly rubs the ball, hooks the corner ball or even pushes the ball on the net to create the opportunity to smash vigorously in the midfield. This kind of tactics must be able to control the drop point of kill and drop ball well, and only when the other side returns the ball passively, can he take the initiative and quickly surf the net.
No matter how to deal with the opponent's body, we should play the diagonal attack and turn the ball slowly. In this way, the other side moves difficultly and passively, creating attack opportunities for our side.
Defense and Counterattack Tactics: when the other side is active and our side is passive, we can catch and kill the net with high quality; or we can seize the opportunity that the opponent's attack and kill strength is weakened or the landing point is not good, and return to the opponent's backcourt by drawing the baseline ball to reverse the passive situation and counter attack.
（2） Doubles tactics
Doubles competition is not only a contest between the two sides in terms of technology, tactics and physical strength, but also a contest of the degree of cooperation between the doubles partners. Therefore, before learning doubles tactics, we should first understand the cooperation between the two in the form of standing. In general, there are two forms of one front and one back station and two people separated side (left and right) positions. The man in the back is in charge of the ball in the second half, while the man in the front is in charge of the ball in the second half. This kind of position is good for attack, but not for defense. Therefore, in general, this method is often used in our attack. In this way, each person in charge of half of the field, there is no room for defense. The form of position is not fixed, it changes with the continuous conversion between attack and defense in the game. The rotation position of doubles is mostly used when the level of paired players is not different. If there is a big difference in technical level, the one with good level will stand in the back field. He is mainly responsible for the ball coming from the second half and also the ball near the midfield or in the front court. In mixed doubles, this kind of fixed position is more common (male players stand in the back court, female players stand in the front court).
In a word, doubles matches have higher requirements on all aspects of pairing, and there are many ways to cooperate with each other. Beginners can gradually master the rules through actual combat practice.
1 attack tactics: concentrate on attacking the person with obvious weakness in the opponent, and wait for the opportunity to attack another person, or sneak attack on this person. In the match, there is always a better match between the two players. Even if the level of two people is not much different, but if you can concentrate on attacking one of them, it can also cause great psychological pressure and make mistakes.
2 attack middle tactics: when the other side stands on defense, attack the ball between the two opponents; when the other side stands back and forth, the ball can be pressed down or pushed flat on both sides of the half. In this way, it can make the other side fight for each other or give in and make mistakes.
3 attack backcourt tactics: the opponent's smashing ability is poor, our side can use the level high ball, push the flat ball, pick the bottom line, and press the other side to move in the two corners of the bottom line. When the opponent seizes the opportunity, he will fight back. If the other opponent retreats to support, you can attack the net front space.
4. Back attack and front blocking tactics: when the side is in the position before and after the active attack, the players standing in the back field will kill or hang the front ball when they see the high ball, forcing the other side to catch the ball and block the net in front of the net, which creates the opportunity of blocking and killing for the front court players of our side. Front court players should actively block the net, forcing the other side to lift the ball passively. Once the opponent's lob can not reach the back court, it creates an opportunity for the side to attack again.
5 defensive counter offensive tactics: looking for the opportunity of counterattack in defense, in order to get rid of the predicament and turn from passive to active. For example: pick the baseline lob, that is, no matter where the opponent attacks, our side should try to pick the ball to the other side of the attacker's baseline. If the opponent's backcourt forehand attack straight line, pick the diagonal line, if the opponent attacks the opposite corner, pick the straight line. This is a kind of defensive tactics which is easy to win the initiative and is more effective in women's doubles. When the opportunity is favorable, you can use the backdraft or block the net to return the opponent's killing ball, and fight for the initiative from the defense. When using this tactic, we should pay attention to the bottom line of the lob, otherwise there will be a situation that the other side will attack and kill continuously but our side can't counterattack
