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. 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.
The shuttlecock is a feathered projectile whose unique aerodynamic properties cause it to fly differently from the balls used in most racquet sports; in particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly than a ball. Because shuttlecock flight is strongly affected by wind, competitive badminton is always played indoors. Badminton is also played outdoors as a casual recreational activity, often as a garden or beach game.
Badminton is an Olympic sport with five competitive disciplines: men's and women's singles, men's and women's doubles, and mixed doubles, in which each pair is a man and a woman. At high levels of play, the sport demands excellent fitness: players require aerobic stamina, strength, and speed. It is also a technical sport, requiring good motor coordination and the development of sophisticated racket skills.
To win in badminton, players need to employ a wide variety of strokes in the right situations. These range from powerful jumping smashes to delicate tumbling net returns. Often rallies finish with a smash, but setting up the smash requires subtler strokes. For example, a netshot can force the opponent to lift the shuttlecock, which gives an opportunity to smash. If the netshot is tight and tumbling, then the opponent's lift will not reach the back of the court, which makes the subsequent smash much harder to return.
