Can you tell me the basics of badminton rackets?

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.

Second, badminton rackets

At present, the most popular rackets are: aluminum alloy racket frame steel ball racket, aluminum alloy racket frame carbon racket and synthetic fiber racket with carbon as the main material. The length of the racket is no more than 68 cm, of which the length of the handle and the racket shaft is no more than 40 cm, the length of the racket frame is 28 cm and the width is 23 cm. With the development of science and technology, the development of racket is developing in the direction of lighter weight, harder racket frame and better flexibility of racket shaft.

Third, badminton net.

The badminton net is 6 10/0cm long and 76cm wide. The top 7.5 cm of the net is sewn in half with white, passed through with thin steel wire ropes, and hung on the net columns at both ends (the height of the center of the net is off the ground 1.524 m, and the two ends of the net column are off the ground 1.55 m). The net is generally made of dark green or dark brown high-quality rope, about 2 cm long.

Fourth, badminton column.

Badminton net column is1.55m high and made of iron. The standard net column consists of two parts: column and column chassis. A pulley device is arranged near the middle of the column to tighten the rope for pulling the net. The doorpost chassis is made of a certain amount of iron and connected with the lower end of the doorpost to ensure the balance of the center of gravity of the net post.

Five, standing to 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).

6. Clap with or without 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.

Seven, 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 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.

Eight, racket angle and racket 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.

Nine, the hitting point

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 be done as follows: 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.
