Definition • Badminton is a racquet sport played by either two opposing players (singles) or two opposing pairs (doubles), who take positions on opposite halves of a rectangular court that is divided by a net
How to Score? • Players score points by striking a shuttlecock with their racquet so that it passes over the net and lands in their opponents' half of the court • A rally ends once the shuttlecock has struck the ground, and the shuttlecock may only be struck once by each side before it passes over the net
Shuttlecocks • A shuttlecock (often abbreviated to shuttle and also known as a bird or birdie) is a high-drag projectile, with an open conical shape: the cone is formed from sixteen overlapping goose feathers embedded into a rounded cork base. The cork is covered with thin leather • Shuttles with a plastic skirt are often used by recreational players to reduce their costs as feathered shuttles break easily.
Rackets • Badminton rackets are light, with top quality rackets weighing between about 70 and 100 grams (without strings) • They are composed of many different materials • Carbon fiber composite • Aluminum • Wood
Strings • Badminton strings are thin, high performing strings in the range of about 0.65 to 0.73 millimeters thickness • Thicker strings are more durable, but many players prefer the feel of thinner strings • String tension is normally in the range of 80 to 130 newtons(18 to 36 lbf)
Strings • Recreational players generally string at lower tensions than professionals, typically between 18 and 25 lbf(110 N) • Professionals string between about 25 and 36 lbf (160 N) • It is often argued that high string tensions improve control, whereas low string tensions increase power
Scoring System • The scoring system changed in May 2006 • Each game is played up to 21 points, with players scoring a point whenever they win a rally • A match is the best of three games
Serve In General • At the start of the rally, the server and receiver stand in diagonally opposite service courts • The server hits the shuttlecock so that it would land in the receiver's service court • A badminton serve must be hit from below the waist in underhand form
Serve for Singles • In singles, the server stands in his right service court when his score is even, and in his left service court when his score is odd
Serve for Doubles • In doubles, if the serving side wins a rally, the same player continues to serve, but he changes service courts so that he serves to each opponent in turn • When the serving side loses a rally, the serve passes to their opponents (unlike the old system, there is no "second serve")
Serve for Doubles • If their new score is even, the player in the right service court serves; if odd, the player in the left service court serves • The players' service courts are determined by their positions at the start of the previous rally, not by where they were standing at the end of the rally • A consequence of this system is that, each time a side regain the service, the server will be the player who did not serve last time
Details • When the server serves, the shuttlecock must pass over the short service line on the opponents' court or it will count as a fault • If the score reaches 20-all, then the game continues until one side gains a two point lead (such as 24-22), up to a maximum of 30 points (30-29 is a winning score)
Details • At the start of a match a coin is tossed • The winners of the coin toss may choose whether to serve or receive first, or they may choose which end of the court they wish to occupy • Their opponents make the remaining choice • In less formal settings, the coin toss is often replaced by hitting a shuttlecock into the air • whichever side it points to serves first
Details • In subsequent games, the winners of the previous game serve first • For the first rally of any doubles game, the serving pair may decide who serves and the receiving pair may decide who receives • The players change ends at the start of the second game • If the match reaches a third game, they change ends both at the start of the game and when the leading pair's score reaches 11 points
Details • The server and receiver must remain within their service courts, without touching the boundary lines, until the server strikes the shuttlecock • The other two players may stand wherever they wish, so long as they do not unsight the opposing server or receiver.
