Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it It is also a technical sport, requiring good motor coordination and the . The doubles court is wider than the singles court, but both are of the same For the first rally of any doubles game, the serving pair may decide who. The clip captures just one single point being scored, but the rally which takes place before we get to it is what Best of Badminton Semifinals. Final men's (MS) and women's (WS) singles matches 'timing factors', type of ' shots' and players' trajectories executed during the match.
For instance, a recent study on the Beijing Olympic Games analysis revealed a percentage of unforced error at about In another study with national level players Taiwanese playersthe percentage of unforced errors increases to Liddle et al reported that However, Ming et al.
This suggests that the Badminton game has considerably evolved over the last two decades and that the notational analysis appears to be a good way to understand this change over time. Up to now, studies on Badminton game characteristics focused on isolated match analysis.
It is hypothesized that Badminton has become more intensive with a higher number of offensive strokes.

For validating this hypothesis, it is expected to observe an increase in the shot frequency, a decrease in the rest time and a change in the distribution of the strokes.

Spin Balls may be spun to alter their bounce for example, topspin and backspin in tennis or trajectory, and players may slice the ball strike it with an angled racquet face to produce such spin.
The shuttlecock is not allowed to bounce, but slicing the shuttlecock does have applications in badminton. See Basic strokes for an explanation of technical terms. Slicing the shuttlecock from the side may cause it to travel in a different direction from the direction suggested by the player's racquet or body movement. This is used to deceive opponents.
Slicing the shuttlecock from the side may cause it to follow a slightly curved path as seen from aboveand the deceleration imparted by the spin causes sliced strokes to slow down more suddenly towards the end of their flight path. This can be used to create drop shots and smashes that dip more steeply after they pass the net. When playing a net shot, slicing underneath the shuttlecock may cause it to turn over itself tumble several times as it passes the net. This is called a spinning net shot or tumbling net shot.
The opponent will be unwilling to address the shuttlecock until it has corrected its orientation. Due to the way that its feathers overlap, a shuttlecock also has a slight natural spin about its axis of rotational symmetry. The spin is in a counter-clockwise direction as seen from above when dropping a shuttlecock. This natural spin affects certain strokes: The shuttlecock is also extremely aerodynamically stable: One consequence of the shuttlecock's drag is that it requires considerable power to hit it the full length of the court, which is not the case for most racquet sports.
The drag also influences the flight path of a lifted lobbed shuttlecock: With very high serves, the shuttlecock may even fall vertically. Other factors When defending against a smash, players have three basic options: In singles, a block to the net is the most common reply. In doubles, a lift is the safest option but it usually allows the opponents to continue smashing; blocks and drives are counter-attacking strokes but may be intercepted by the smasher's partner.
Many players use a backhand hitting action for returning smashes on both the forehand and backhand sides because backhands are more effective than forehands at covering smashes directed to the body. Hard shots directed towards the body are difficult to defend. The service is restricted by the Laws and presents its own array of stroke choices. Unlike in tennis, the server's racquet must be pointing in a downward direction to deliver the serve so normally the shuttle must be hit upwards to pass over the net.
The server can choose a low serve into the forecourt like a pushor a lift to the back of the service court, or a flat drive serve.
Lifted serves may be either high serves, where the shuttlecock is lifted so high that it falls almost vertically at the back of the court, or flick serves, where the shuttlecock is lifted to a lesser height but falls sooner. Deception Once players have mastered these basic strokes, they can hit the shuttlecock from and to any part of the court, powerfully and softly as required. Beyond the basics, however, badminton offers rich potential for advanced stroke skills that provide a competitive advantage.
Because badminton players have to cover a short distance as quickly as possible, the purpose of many advanced strokes is to deceive the opponent, so that either he is tricked into believing that a different stroke is being played, or he is forced to delay his movement until he actually sees the shuttle's direction. When a player is genuinely deceived, he will often lose the point immediately because he cannot change his direction quickly enough to reach the shuttlecock.
Experienced players will be aware of the trick and cautious not to move too early, but the attempted deception is still useful because it forces the opponent to delay his movement slightly.

Against weaker players whose intended strokes are obvious, an experienced player may move before the shuttlecock has been hit, anticipating the stroke to gain an advantage.
Slicing and using a shortened hitting action are the two main technical devices that facilitate deception.
Slicing involves hitting the shuttlecock with an angled racquet face, causing it to travel in a different direction than suggested by the body or arm movement. Slicing also causes the shuttlecock to travel more slowly than the arm movement suggests.
For example, a good crosscourt sliced drop shot will use a hitting action that suggests a straight clear or a smash, deceiving the opponent about both the power and direction of the shuttlecock. A more sophisticated slicing action involves brushing the strings around the shuttlecock during the hit, in order to make the shuttlecock spin. This can be used to improve the shuttle's trajectory, by making it dip more rapidly as it passes the net; for example, a sliced low serve can travel slightly faster than a normal low serve, yet land on the same spot.
Spinning the shuttlecock is also used to create spinning net shots also called tumbling net shotsin which the shuttlecock turns over itself several times tumbles before stabilizing; sometimes the shuttlecock remains inverted instead of tumbling. The main advantage of a spinning net shot is that the opponent will be unwilling to address the shuttlecock until it has stopped tumbling, since hitting the feathers will result in an unpredictable stroke. Spinning net shots are especially important for high-level singles players.
The lightness of modern racquets allows players to use a very short hitting action for many strokes, thereby maintaining the option to hit a powerful or a soft stroke until the last possible moment. For example, a singles player may hold his racquet ready for a net shot, but then flick the shuttlecock to the back instead with a shallow lift when she or he notices the opponent has moved before the actual shot was played.
A shallow lift takes less time to reach the ground and as mentioned above a rally is over when the shuttlecock touches the ground. This makes the opponent's task of covering the whole court much more difficult than if the lift was hit higher and with a bigger, obvious swing. A short hitting action is not only useful for deception: A big arm swing is also usually not advised in badminton because bigger swings make it more difficult to recover for the next shot in fast exchanges.
The use of grip tightening is crucial to these techniques, and is often described as finger power. Elite players develop finger power to the extent that they can hit some power strokes, such as net kills, with less than a 10 centimetres 4 inches racquet swing. It is also possible to reverse this style of deception, by suggesting a powerful stroke before slowing down the hitting action to play a soft stroke. In general, this latter style of deception is more common in the rear court for example, drop shots disguised as smasheswhereas the former style is more common in the forecourt and midcourt for example, lifts disguised as net shots.
Deception is not limited to slicing and short hitting actions. Players may also use double motion, where they make an initial racquet movement in one direction before withdrawing the racquet to hit in another direction. Players will often do this to send opponents in the wrong direction. The racquet movement is typically used to suggest a straight angle but then play the stroke crosscourt, or vice versa.

Triple motion is also possible, but this is very rare in actual play. An alternative to double motion is to use a racquet head fake, where the initial motion is continued but the racquet is turned during the hit. This produces a smaller change in direction but does not require as much time. Strategy This section does not cite any sources. September Learn how and when to remove this template message 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 net shot can force the opponent to lift the shuttlecock, which gives an opportunity to smash. If the net shot 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.
Deception is also important. Expert players prepare for many different strokes that look identical and use slicing to deceive their opponents about the speed or direction of the stroke. If an opponent tries to anticipate the stroke, he may move in the wrong direction and may be unable to change his body momentum in time to reach the shuttlecock. Singles Since one person needs to cover the entire court, singles tactics are based on forcing the opponent to move as much as possible; this means that singles strokes are normally directed to the corners of the court.
Players exploit the length of the court by combining lifts and clears with drop shots and net shots. Smashing tends to be less prominent in singles than in doubles because the smasher has no partner to follow up his effort and is thus vulnerable to a skillfully placed return.
