===Biomechanics===

Badminton [[biomechanics]] have not been the subject of extensive scientific study, but some studies confirm the minor role of the wrist in power generation and indicate that the major contributions to power come from internal and external rotations of the upper and lower arm.{{sfnp|Kim|2002}} Recent guides to the sport thus emphasize forearm rotation rather than wrist movements.<ref>{{citation |contribution-url=http://www.badmintonengland.co.uk/text.asp?section=0001000100070007 |contribution=Badminton Technique |title=Badminton England |url=http://www.badmintonengland.co.uk }} {{cite web |url=http://badmintonengland.co.uk/text.asp?section=0001000100070007 |title=Videos / DVDS - Badminton England |access-date=2015-12-06 |url-status=dead |archive-url=https://web.archive.org/web/20080417212505/http://www.badmintonengland.co.uk/text.asp?section=0001000100070007 |archive-date=17 April 2008 |df=dmy-all }}</ref>

The feathers impart substantial drag, causing the shuttlecock to decelerate greatly over distance. The shuttlecock is also extremely aerodynamically stable: regardless of initial orientation, it will turn to fly cork-first and remain in the cork-first orientation.

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: the [[parabola]] of its flight is heavily skewed so that it falls at a steeper angle than it rises. With very high serves, the shuttlecock may even fall vertically.
