Comparisons of technique
What is the wrist?
Badminton
Badminton and tennis techniques differ substantially. The lightness of the shuttlecock and of badminton rackets allow badminton players to make use of the wrist and fingers much more than tennis players; in tennis the wrist is normally held stable, and playing with a mobile wrist may lead to injury. For the same reasons, badminton players can generate power from a short racket swing: for some strokes such as net kills, an elite player's swing may be less than . For strokes that require more power, a longer swing will typically be used, but the badminton racket swing will rarely be as long as a typical tennis swing. It is often asserted that power in badminton strokes comes mainly from the wrist. This is a misconception and may be criticised for two reasons. First, it is strictly speaking a category error: the wrist is a joint, not a muscle; the forearm muscles control its movement. Second, wrist movements are weak when compared to forearm or upper arm movements. 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. Modern coaching resources such as the "Badminton England Technique DVD" reflect these ideas by emphasising forearm rotation rather than wrist movements.
