Comparisons of technique
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 10cm. 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 — wrist movements are weak when compared to forearm or upper arm movements.
