There is now a strong emphasis on physical exercise and public health, making badminton a great choice. For beginners, here’s how to choose a racket that suits you. Experienced players or those who have been playing for many years can skip this section.

Badminton rackets come with many parameters, but for beginners, focusing on a few key points should be sufficient:

1. Racket Length: The standard length of a badminton racket is 665mm, though some rackets can reach up to 675mm. A longer racket provides a greater reach for control, while a shorter racket offers more maneuverability. This small difference can affect how you play.
2. Racket Material and Weight: The material and weight of the racket greatly impact your playing experience and can also affect the price. Racket weight is indicated in U, as follows:
   • 1U: 95-99.9 grams2U: 90-94.9 grams3U: 85-89.9 grams4U: 80-84.9 grams
   If you have more power and prefer an aggressive play style, a heavier racket might be suitable. If you prefer better control, a lighter racket would be a better choice.
3. String Tension: For beginners, a string tension between 20-25 pounds is usually sufficient. Anything higher might be difficult to control.

For amateurs, 25lbs or more would be considered a high poundage. Professional badminton women’s racket line pounds will reach 26 to 30 pounds, even if it is the second team of female players, pounds will be in 26 pounds, while most of the male players are between 30 to 33 pounds. However, non-professional amateurs must not blindly imitate the idol, the pursuit of high poundage, affecting the level of small things, resulting in injuries.

The higher the poundage of the racket line, the tighter the line will be, and the harder the racket surface will be. The force of the ball hitting the racket surface to the arm will also be greater. Professional athletes have been trained to swing their arms back to the ball with enough force to reduce the impact of the ball, and the stiffer the racket surface, the better they can find the control point and increase the accuracy of their shots.

However, the arm strength of the average amateur is not enough to resist the impulse of the incoming ball, which can easily cause injuries to the wrist, elbow or shoulder joints. Therefore, many professional stringers will recommend that amateurs do not pursue a high poundage, but gradually increase the poundage according to their own level of play. Cheng Bin suggests that beginners generally 18 to 21 pounds is enough, intermediate level enthusiasts can choose 20 to 21 pounds, while the poundage can reach 25 to 26 pounds of enthusiasts, the level has been quite good.

The racquets in the hands of the players are not only dazzling, but they are also the result of high technology. A good racket can not only help them achieve good results, but also protect their bodies and reduce sports injuries. However, players of different sports have different characteristics and use different racquets. Even if the models are the same, the players themselves will change certain details of the racquets according to their own characteristics, so as to make sure that the racquets are more suitable for their own needs.

Singles players such as Lin Dan and Park Sung Hwan use racquets with a stiff centre stick, which is strong enough to withstand the power that erupts during their kills, and a heavy head, which adds to the stability of the kills. Doubles players such as Lee Yong Dae, Lee Hyo Jung, Cai Yun, Fu Haifeng, etc. have relatively softer shafts in their rackets. This is due to the fast speed of doubles matches and the many changes at the net, which require players to be flexible at all times, so this kind of racket makes them play better.

In addition, players have a lot of tricks to increase the flexibility of the racket, wrapping tape around the handle is one of them. Lin Dan’s racket has a layer of coarse-textured cloth wrapped around the handle, which, needless to say, is used to increase the friction of the handle, so that when holding the racket, even if the palms of the hands are sweaty, the stability of the grip can be maintained to the greatest extent possible. You know, stability is especially important for players like Lin Dan to kill as a killer. However, Lin Dan said: “The coach said this is not good, it is easy to hurt the hand, but I have been used to it, since childhood, so wrapped, playing to the present is not much of a problem, in fact, quite good.”

For doubles players racket, the tape will generally be wrapped more on, a stringing division said to have seen the tape wrapped to the middle of the middle of the racket, “the middle of the rod is only about 10 cm of the length of the light, the following parts of the tape are wrapped.” This is also due to the fact that doubles net requires quick and flexible changes, and the grip allows the racket to be as short as possible. It is like the short sword in the weapon, which is more capable of making quicker moves to win in a short match at close range.

Firstly, each team must have a minimum of 4 players (2 men and 2 women) and an athlete may only play a maximum of two times in a team match. In the case of only 4 players, each athlete must play two matches, i.e. both men’s and women’s doubles, plus singles or mixed doubles. If, on arrival at the place of competition, due to illness or injury, etc., there are fewer than 4 players (only 1 man and 2 women or 2 men and 1 woman), the number of matches that cannot be played in a team match is treated as a losing match. In the event that a team has only 1 man and 1 woman left, that team match is cancelled.

Secondly, the list of athletes to play in each team competition shall be submitted by each team leader to the referee 4 hours before the start of the competition, or in the case of semi-finals and finals of the highest group (group of 1 to 8 places), 8 hours before the start of the competition. After the submission of the list, if any athlete is unable to compete due to illness or accident, the head referee may agree to replace the athlete, but the replaced athlete will not be allowed to compete in that team competition.

Thirdly, at the same time of submitting the list, each team leader may provide the referee with his/her team’s suggestions on the starting order of the five races for his/her reference, and the final order of the races shall be decided by the referee. If there is a problem of unavoidable back-to-back races for an athlete due to a combination of events, there should be a 30-minute interval between the athlete’s two consecutive races.

Fourthly, in the first stage of the team competition, a round robin is played and all five matches in each team competition must be played. Whereas in non-round robin matches (semi-finals and finals), when one side wins three matches, the remaining two or one match is not played.

In the first stage of the group round robin, the ranking is determined by the order of the team’s wins. If two teams are equal in terms of wins, they are ranked according to the number of matches won or lost between them, and the winner is ranked first; if three or more teams are equal in terms of wins, the ranking is determined by their wins from all the matches played in the group; and if they are equal again, the ranking is determined by the number of games won from all the matches they played in the group.

(Note: In the BWF competition regulations, we call a team match “TIE”, a singles or doubles match “MATCH”, and “court”. A singles or doubles match is called a “MATCH”, a “GAME” is called a “GAME”, and a “POINT” is called a “POINT”. “POINT” we call it)

The first point above is not a big problem for the first group at the highest level, as these teams have a sufficient number of dedicated singles and doubles players. The remaining three points, on the other hand, lead to many variations.

Choosing the order of play tests the level of team scheduling

In the first few tournaments from 1989 onwards, every team match had to be played all five games, which made sense in the first stage of the group round robin, because the way the group round robin determines the ranking order requires each team to value every game, set and point won. But in non-round-robin play, when a team has already won three games in a team game, it becomes redundant to play the remaining game (or two). Although the “rules” require that all five matches be played in order to allow spectators to enjoy more matches, the fact is that the athletes are not interested in playing because the outcome of the matches has already been decided. The scores of the semi-finals and finals of the previous editions showed that when one side scored three points, the rest of the match was abandoned.

In 1993, it was changed to “In the semi-finals or finals, when the result of the match has been decided, the referee may decide whether or not to play the remaining matches”, and in 2001, it was simply changed to “In non-round-robin group matches, when the winner has been decided, the remaining matches will not be played”. “.

To sum up the above aspects, the order of matches is an issue that needs to be carefully considered by the coaches of each team when arranging their matches. Because two teams of comparable overall level have different winning percentages in the five individual events, the psychological impact of winning or losing the first match of a team competition on the whole team is very obvious, and teams would like to have the event with the higher winning percentage of their team to be arranged in the first match. Most teams often have an athlete in the men’s doubles and women’s doubles who needs to play mixed doubles as well, so there is a lot to be said about which doubles or mixed doubles match the athlete who plays both disciplines will play first. For example, there was a Su Cup match, team A’s women’s doubles strength is clearly superior, and team B’s a women’s doubles to mixed doubles, team A wants to women’s doubles to play first, one of the total score can be ahead of the other is in the women’s doubles, try to consume the physical strength of the mixed doubles athletes of team B and mixed doubles for the mixed doubles match to open up the way.

The SU Cup Competition Regulations do not prescribe or suggest in principle the order of the five matches in the team competition. When the referee receives the lists of players from both sides of the competition and the proposed order of matches, if both sides have the same attitude, there is no problem. If there is no agreement, the referee will generally take the order in which neither side has a concurrent athlete playing back-to-back matches as the preferred option, and try to space two matches between the two matches of the concurrent athlete. As to which item is played first, it is generally: if singles and doubles, singles is played first; if doubles and mixed doubles, mixed doubles is played first, but it is also entirely up to the head referee to personally combine all factors. In other words, although the head referee is not bound by any constraints in making the decision on the order of matches, it also reflects the overall business level of the head referee.

As a leading coach, apart from building a strong team, he should also be well versed in the competition rules and regulations and be good at mobilising his favourable factors and making good relationships with all parties, which is also crucial to winning key battles.

Round-robin tournament

The team competition of badminton adopts more single round-robin tournaments. But generally also use group, stage by stage method, because the round-robin tournament game number of games, long time, in the number of teams or the number of participants in a larger number of times is not applicable. The round-robin method of play is that all teams in the same group take turns playing each other once.

The ranking of the match is based on the number of wins, or if two teams have the same number of wins, the winner of the match between the two teams will be ranked first. If there is a tie between three or more winners, it is decided by the number of net games they have won throughout the stage (single events are decided by the number of net sets won). Once there is a tie between two, the winner of the match between the two is placed first. If there is still a tie between three or more, the net wins and net points will be calculated again accordingly. If there is still a three-way tie in net win points, they are ranked by drawing lots. Therefore, in a round-robin tournament, when the participants are evenly matched in terms of skill level, every game, every set and every point in the match will most likely have a bearing on the final ranking.

If there are two teams (or participants) from the same organisation in a group, the matches between them should be arranged first, so as to avoid “watering down” each other in the later rounds and playing fake games. Even so, in the round-robin tournament, it is still impossible to prevent the phenomenon of ball-fixing or “watering”, which is a disadvantage of the round-robin tournament system.

Single elimination tournament

Badminton competition of single event, generally are used in single elimination tournament, because the number of participants in a tournament, the game can only be used in single elimination tournament. Single-elimination tournament method is the participants in accordance with the number of 2 multiplier (4, 8, 32 ……) to fight against each other. The winner moves on to the next round, the loser is out immediately, and half of the participants are eliminated in each round. So the whole game is fast and furious. Any negligence on the part of the contestants may result in their immediate elimination.

The arrangement of the rounds of the competition is related to the intensity of the competition and the gradual escalation of the competitive level of the competition, so the rounds of the competition are required to be arranged for one round per day (or evenly distributed). If this is not possible, then extra rounds should be scheduled in the first few rounds, and the semi-finals and finals, which are close in level, should never be scheduled on the same day.

Seeding and Drawing In. Knockout rounds are highly opportunistic. In order for the outcome of the tournament to be reasonable, it is necessary to seed the higher level entrants as evenly separated. Contestants from the same unit must also be evenly separated to meet at the end.

Mixed system of round robin and elimination

In order to make the game end in a shorter time, but also to make the results of the game is more reasonable, in many tournaments on the round-robin and elimination tournament used in combination. Generally in the first phase of the group round robin, the second phase of the elimination. For example, the Thomas Cup, Uber Cup, Sudirman Cup, and World Badminton Grand Prix Finals are all mixed round robin and knockout tournaments. (b) The World Badminton Grand Prix Finals.

Since in badminton sports should be “playing what ball on what racket”, then, can in the process of hitting the skilled conversion of a variety of ways to grip the racket is particularly important. If you can according to the following steps unremittingly practice, practice makes perfect, work to the natural success.

1. Learn the basic forehand and backhand grips carefully, because all kinds of grips are changed on the basis of this.
2.  Always hold the racket loosely except at the moment of hitting the ball.
3. On the basis of mastering the basic grip, when learning other strokes, you should be good at experiencing and learning different grips. For example, the same forehand ball, hanging the diagonal and hanging the straight line of the ball when the grip should be slightly changed. The more grip methods you master, the finer the distinction between the various methods, and the easier it will be to change.
4. Usually, you can put the racket in the hands of more unarmed change practice, the racket according to their own idea of changing the racket, and constantly change and restore the movement, in order to develop finger dexterity. Such as from the forehand grip into a backhand grip, and then quickly return to the forehand grip; from the end of the grip in the handle suddenly moved to the front of the handle (in the doubles serve, net blocking and flat blocking, usually using this grip), and then quickly slipped back to the basic grip, and so on.
5. on the basis of the above, can be combined with some footwork to move some change grip practice, badminton combat grip change, the vast majority of them are in the middle of the start and move to complete, that is to say, it is in the middle of the process of the lead shot to complete. If you can combine the footwork and the lead shot practice, to achieve the degree of proficiency, the effect can be imagined.

In badminton, the grip is really a seemingly simple, but the learning is very deep. Do not say is a beginner in learning to grip will be prone to all kinds of easy to make mistakes, even if it is a badminton professional athletes, but also often because of the errors in the grip and affect the further improvement of its technical level.

Beginners in the learning of the basic grip, mainly easy to appear the following errors:

1.  Adopt the “western style” grip method grip. This grip method in badminton batting, mainly in the near net pouncing ball and sealing the net is more often used.
2. “A grasp” grip, that is, the index finger is lower than the thumb and the middle finger and hold the racket together.
3. The index finger is too far forward and directly pressed on the top of the racket handle, making it difficult to grip the racket tightly at the moment of hitting.
4. Gripping the racket too tightly before hitting the ball, leaving no space between the palm and the handle. This directly affects the flexibility of the grip and the power at the moment of striking the ball.
5. When gripping the racket, the piriformis muscle is not flush with the end of the handle, resulting in the end of the handle being exposed. This is the correct grip for doubles serves, flat blocks and net closures, but should not be used in general. Similarly, it is not appropriate to hold the racket too far back.

The correct grip for badminton is relatively easy to learn, but it is not so easy to really master in the actual use of the racket. Therefore, it is inevitable to make some mistakes when you first learn, even if you are fortunate enough to have the guidance of a master, but also because you have not yet fully grasped the essentials of hitting, the grip will often go out of shape, and often back to the original wrong action. Therefore, in the process of batting practice, we must develop a good habit of reminding ourselves to “check whether the grip is correct”, which is especially important for a beginner, so that after a period of training, it will not be difficult to learn the correct way to grip the racket.

Badminton ball speed, weight, calibre of the relationship:

The flight speed of badminton in the same area is mainly determined by its overall weight, calibre, hair type, left and right hair points, head and body weight ratio, generally speaking, the same ball factory factory badminton ball calibre is fixed, for example, Golden Eagle brand badminton ball calibre standard: 66.5mm plus or minus 0.5mm, that is, in the 66-67mm, this time to determine the speed of the ball the main factors in the ball overall weight and head and body weight ratio, for the head and body weight ratio we have strict standards to control in order to ensure that badminton ball speed, weight, calibre. The main factor to determine the speed of the ball is in the overall weight of the ball and the weight ratio of the head and body of the ball, for the weight ratio of the head and body of the ball we have strict standards to control to ensure that the flight performance of badminton balls. So generally according to the overall weight of the ball can know its approximate flight speed, also can know it applies to what area.

What kind of badminton ball should be chosen for different altitude and climate areas?

The most basic requirement of playing badminton is that the speed or weight of the ball must be suitable, otherwise it will be difficult to play a lot of techniques. And the same weight of badminton in different areas of the flight speed will have a big difference, because the weight of the ball and the altitude and climate has a very close relationship, high altitude air density is small feather ball in the flight of the air resistance is small, so high altitude with the weight of the badminton ball should be reduced. Low altitude air density, badminton flight by the air resistance is large, so the weight of badminton with low altitude areas to be a little heavier. Take the golden eagle brand products for example: Shanghai: 5.2 grams, Guangzhou: 5.1 grams, Kunming: 4.7 grams, Chengdu: 4.9 grams. In addition, the dryness and humidity of the air, the temperature of the high and low on the speed of badminton also has a certain impact, but the altitude of the most obvious impact.

What are the disadvantages of using too heavy or too light badminton for racket and human body?

The overall weight of the badminton ball is too heavy or the head is too heavy, the vibration caused when hitting the ball is bigger, the impact on the racket and the string is bigger, it will reduce the service life of the racket and the string, the most obvious one is that the service life of the string will be shortened greatly, and on the other hand, the vibration caused by the racket and the string will be transferred to the player’s arm, and in a long time, it will also have some bad effects on the arm. If the weight of the badminton ball is too light, due to the hit is not in place, the hitter will send out more power to achieve the purpose of the hit in place, which is easy to cause arm fatigue, arm injury. So choosing the right weight of badminton will not only make you enjoy the fun of badminton better, but also reduce your risk of injury.

The difference between high-grade products and low-grade products:

In addition to the appearance of the main difference lies in the flight performance of the ball, that is, the stability of the feather ball, speed, hit by the deformation of the degree of flight rotation, high-grade badminton on the high requirements of the hair piece, a ball on the 16 hair piece requirements of the shape and quality of almost the same, in order to ensure that the feather ball of the high standard of requirements, which results in a higher price of it.

Badminton ball hair hair quality identification:

High-quality badminton feathers must use high-quality goose feathers. Goose feathers strength, toughness are particularly suitable for badminton requirements, but its high cost and the supply of raw materials is limited, so in some of the requirements of the badminton manufacturers use duck feathers, alone from the appearance of the difficult to distinguish between duck feathers and goose feathers, and well-crafted duck feather feather feather badminton flight performance is also very good, due to the two kinds of hair pieces of the hair stalk structure is not the same, and its resistance to play than the goose feather feather feather feather badminton to be poorer, a lot, in the normal stroke of the feather feather feather feather feather feather feather feather feather feather feather feather feather feather feather feather feather feather feather feathers. Due to the different structure of the two kinds of hairs, their durability is much worse than that of goose feather badminton, it is easy to break in normal batting, because the price of duck feather is much lower than that of goose feather, the use of duck feather can effectively reduce the cost.

Classification of badminton hair:

High-quality badminton hair must be used goose blade hair, if the use of duck blade hair and other hair pieces it is difficult to guarantee the quality.

The classification of the ball hair is very complex, because there is no national unified classification of the number of standards, the various manufacturers of badminton production of the mark are self-defined, different producers if there is the same mark of the product does not mean that their quality is the same. Jinhe factory as an example: where the middle and high grade badminton, that is, with the “A” word of the product are used to live plucking white goose plume hair, first of all in accordance with the hair type classification for large, medium and small hair, and then in accordance with the quality of the hair is divided into a one, two, three, four, and then according to the hair of the curved and warped each divided into five standards, and then according to the thickness of the hair stalks, hair pieces of the thick and thin to the similar Hair pieces are categorised according to the thickness of the hair stalks and the thickness of the hair pieces. In the same badminton on the use of 16 feathers must be the same class and to try to be similar, the more high-grade products using the 16 pieces of hair more consistent in order to ensure the flight quality of the product. Low-grade products, i.e. general recreational use of the ball our factory also uses white goose feather, camel hair, its processing technology and high-grade products consistent, to ensure the beauty and durability.

Badminton ball head classification:

According to the material used in common: hard plastic, foam, cork these three, the first two are mainly used for low-grade recreational badminton, lower cost performance is poor. High-grade badminton is the use of natural cork ball head, and cork ball head can be roughly divided into three categories: the whole cork ball head, composite cork ball head, regeneration cork ball head.

Red and yellow cards are commonplace in football, but what do they mean in badminton?

• When a badminton player commits the first offence under Rules 16.4, 16.5 or 16.6 in a match, the referee will warn the offending player with a yellow card.
• If a player who has been warned commits another offence under Rules 16.4, 16.5 or 16.6, the referee will issue a red card to the player concerned.
• When the referee awards a serious infringement or repeated infringement of Rule 16.4, 16.5, or 16.6 and intends to recommend to the referee that the player be disqualified from the match, the referee shall award the offending player a red card and summon the referee.
• At the time the Referee-in-Chief decides to disqualify the player, he will hand the black card to the Referee, who will use the black card to award the player misconduct and disqualify him from the match.

What is rule 16.4, 16.5 or 16.6?

16.4 Delay in play

•  16.4.1 Under no circumstances shall play be delayed such as to regain strength, to catch breath or to receive instruction;
•  16.4.2 The referee is the sole judge of whether or not play has been delayed.

•  16.5.1 Players are permitted to receive instruction during play only when the ball is not in play;
•  16.5.2 No player is allowed to leave the field of play without the referee’s permission.

16.6 A player must not do any of the following.

•  16.6.1 Deliberately delay or interrupt play;
