Novice: both technology and feel are rising. The intuitive feeling is that the higher the pound, the better the elasticity and the better the sound. In fact, the sound is good because you concentrate on the sweet spot of the ball at the same time, not because of the high pound.

Advanced: technology is in a spiral rising period, and the sense of laziness and frustration is intertwined with the sense of gain. The state is prone to ups and downs, and it is easy to have the idea of tossing equipment and threading back and forth, looking for the right number of pounds.

High-level players: In the stable period of technical breakthrough, when the specific number of pounds is determined, it is clear that the performance of equipment is limited, and it is also clear that many balls must be played by themselves, instead of being often attributed to the failure of equipment as in the previous stage, and no longer entangled in various forms of problems, and pursuing performance more important than elasticity, such as ball control.

Badminton mixed doubles competition rules

Badminton mixed doubles adopts the scoring system of 2 1, that is, the player who scores 2 1 wins first and wins 2 games in 3 sets. In each game, if one side scores 2 1 point first and leads by at least 2 points, the game will win, otherwise the game will continue; If the two sides are tied at 29, and one side leads 1 point, the game wins.

In the new competition system, every ball is scored, and players can't ask to interrupt the game except in special circumstances (such as wet floor and broken ball). However, when one side leads 1 1 in each game, 1 minute will be suspended to allow both sides to wipe sweat, drink water and have a rest.

The scorer has the right to serve. If our score is odd now, serve from the left. Now the score is even, 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.

At the beginning of mixed doubles, the service should start from the right service court; Only the receiver and the receiver can receive the service; If his partner catches the ball or is hit by it, the server scores one point. In any game, the receiver scores a point, and then a player of the receiver serves, thus exchanging the right to serve. Note that four players on both sides do not need to change positions when exchanging the right to serve.

Players must not make mistakes in serving and receiving, or serve twice in the same game. Any player who wins a game can serve first in the next game, and any player who loses can receive the service first. After serving, the players of both sides are no longer restricted by the service area, and players can stand on their own court or off-court.

Badminton Common Sense 2 Can you stovepipe while playing badminton?

1, energy consumption

As long as you exercise, you can consume extra energy, not to mention that playing badminton is several times to dozens of times that of sitting quietly at ordinary times, and the energy consumed by playing badminton is closely related to the duration of exercise, which means that the longer you play badminton, the more energy you consume.

Step 2 burn fat

Playing badminton is an aerobic exercise, because through the supply of oxygen, the body's fat will be oxidized and decomposed to generate heat energy for human use, which has the most obvious impact on human fat metabolism. Generally, after playing badminton for more than 30 minutes, the body will consume fat to replenish energy, that is, burn fat.

3. Shape line

When you play badminton, the action of waving the racket is actually that your shoulders, upper arms, forearms and your muscles are doing exercises.

Kicking, striding, jumping and other forward and backward footwork movements can exercise the large muscle groups of buttocks, thighs and calves. The muscles of abdomen, waist and back involved in turning make lean body gain weight and make the body get rid of excess fat.

You may worry that playing badminton for a long time will cause leg muscles, but as long as you control the intensity and time of exercise reasonably and stretch and massage your legs properly after exercise, you don't have to worry about causing leg muscles.

When playing badminton, the legs will continue to move flexibly, which can not only burn fat, but also help stretch and shape the leg lines.

Matters needing attention in playing badminton and stovepipe

1. If you want to lose weight, you should exercise for more than 30 minutes at a time. Heart rate 120- 160 aerobic exercises per minute.

2. The goal and speed of losing weight must be reasonable and practical. The weekly weight loss shall not exceed 1kg, and the total weight loss shall not exceed 10% ~ 15% of the body weight. Setting a reasonable weight loss goal, in addition to safety, gradually reaching the target weight can enhance the confidence of losing weight.

3. Don't use weight loss products of unknown origin and exaggerated effect.

Do a physical examination before losing weight and listen to the doctor's advice, especially for obese patients.

5. Playing badminton for 30 minutes consumes 2.55 kilocalories per kilogram of body weight. So the calories consumed in playing badminton for 30 minutes (kilocalories) = weight (kg) ×2.55. And 1 kg fat =7700 calories. Taking 60 kg body weight as an example, the time (hours) required to subtract 1 kg fat is: 7700÷60÷2.55÷2=25. 1 (hours).

6. The condition of losing weight by exercise is that the oxygen is sufficient and the exercise time is long enough, and the human body will use fat to participate in energy supply. If you don't exercise for 40 minutes at a time, the exercise will be over before you start to consume fat, and the weight loss effect will definitely be bad.

7. It is suggested to take part in some low-intensity and long-term aerobic exercises, such as brisk walking, jogging, long-distance swimming and aerobic exercises.

How long can I play badminton after dinner?

The reason why you can't play badminton immediately after a meal is because the blood flow of the human body will concentrate on digesting food in the stomach after a meal. If you start playing badminton at this time, the blood will flow to the skeletal muscle and the blood supply to the stomach will be reduced, which will cause indigestion.

② Human blood is supplied to the digestive system after meals. If you play badminton immediately after a meal, the blood supply to important organs such as the brain and heart will be insufficient.

If you play badminton after meals, some blood will be supplied to the exercise system, which will affect the normal digestive function of the gastrointestinal tract.

It is ok to take a walk immediately after a meal, but don't do strenuous exercise after a meal. After at least half an hour, you can do strenuous exercise, such as playing badminton.

Therefore, normal people should promote gastrointestinal peristalsis, secretion of digestive juice and digestion and absorption of food 30 minutes after meals under the premise of ensuring normal digestive function.

Common mistakes in badminton.

Many people like playing badminton, but most people make some mistakes. Let's take a look at the common problems in playing badminton.

1, equispherical attitude

When the ball is in the opponent's court, waiting for the opponent to return the ball, many people stand with their feet parallel.

However, it is easier for people to start when standing in front and back, and the starting time is less, so the most obvious success rate before catching the ball is higher and the effect is remarkable.

Step 2 watch the ball

After the ball is hit, I always unconsciously look at the opponent's court.

But in fact, after the ball goes out, you don't have to watch it far away. What's more important is to do what you should do, such as spending some time standing at the station. It's reasonable to spend more time running, but you can't watch the ball completely.

Step 3 stand upright

After the ball was hit, I used to watch the ball float to the opponent's court and wait for the ball to return to my court again, but people did not move.

After the ball goes out, people should immediately return to the position near the center of the field, instead of standing still at the hitting position.

Step 4 hit the ball

The benefits of hitting the ball higher than hitting the ball lower are great, hehe, everyone may have experienced it, but it is very difficult to hit the personal highest point every time, because it is difficult to change the habit, but it is really effective (everyone seems to know it, but few people do it every time, so they usually practice it deliberately).

5. Save the ball in front of the net

It's easy to throw the ball in front of the net, out of bounds and off the net.

If a ball can dive, it is generally a poor quality return ball. At this time, the opponent is easily nervous, and the attacker is often full of confidence and strength. However, due to the short time and the difficulty in adjusting the wrist angle, the ball is easy to go out of bounds and get off the net.

If you spend less effort and don't let the ball go out of bounds or off the net, in fact, in most cases, the attack power is enough to score (because the opponent's preparation time is very short, except for the master).

6. Hold the racket in front of the doubles net

In doubles, the person who seals the net in front of the net may have this habit, and the racket is put down instead of raised.

Generally speaking, if you can hit the ball in front of the net, you usually hit the ball up and down (unless the opponent puts a good ball in front of the net), so the racket usually hits the ball up and down. It takes a little time for the racket to hit the ball from bottom to top, which is very valuable.

Therefore, people in front of the doubles net should keep their rackets up, instead of hanging rackets and other balls.

7. Running without a batter in doubles

In doubles, if one side is returning the ball, the other side often stands there and watches. This is the habit of some people. In fact, idle people should run to a reasonable position.

Badminton common sense 3 basic movements of badminton forehand service

standing position

The singles serve should stand near the center line, about 1 m away from the front serve line. Stand steady and close to the serve line when serving doubles.

Ready posture

The left shoulder of the body faces the net. When serving forehand, it is required to stand in a "T-step", with the left foot in front, the right foot behind and the center of gravity on the right foot.

Hold the racket with your right hand, lift it to the right rear side, relax your elbow slightly, and hold the ball between your chest and abdomen with your left thumb, forefinger and middle finger. When serving, the body's center of gravity shifts from the right foot to the left foot (if you are used to playing with your left hand, the preparation posture is completely opposite).

Gripping method

Hold the racket with your fingers together and your thumb close to the club.

Forehand serve essentials

When serving forehand, hold the badminton in your left hand and put it on your chest. Look at the opponent's position from the corner of your eye, then release the badminton with your left hand and keep your eyes on the ball's whereabouts.

At the same time, hold the racket with your right hand and wave your arm from top to bottom. It is best to use the big arm to drive the small arm. The racquet net should be pointed at the badminton head. When the badminton is about to fall in line with the racket net, the wrist will hit the badminton hard forward and upward.

You can lift your heel slightly when hitting the ball, which is helpful for strength. When serving, the hitting position should not be higher than the hand and waist. It is illegal to throw the ball up and hit the ball in the air like tennis.

basic skill

6. Front-side inversion (the body of handball turns backward, and as compensation, the wrist control racket face should also have a corresponding internal rotation angle; When hitting the backhand, the body is fully unfolded, the back is turned to the opponent, the arm swing distance is long, and the wrist force should arrive in time)

7, strong chase slow gear (when the attack is favorable, we should constantly speed up the attack rhythm, arm and wrist movements coherent and rapid; When the opponent is attacking continuously, take the initiative to change the rhythm of the opponent's continuous attack by lightly blocking and letting go.

8. Soft dancing and crisp hitting (all movements of badminton should be very coordinated, even gentle; But the moment of hitting the ball must be crisp and neat. From waist to wrist, there should be a sharp pause in hitting strength, followed by coordinated body movements)
