According to qualitative analyses the activation-relaxation-pattern of the grip forces seems to be a crucial factor of performance in many Badminton techniques. Especially for the backhand net shots it is assumed that experts exert high pressure on the racket handle within a short period of time to utilize the elasticity of the racket whereas athletes on lower level of performance tend to maintain grip forces over a longer period during the final phase of the smash. This is partly supported by EMG analysis [1]. To analyze the movement coordination by the pressure applied on the racket a specific device has been developed.
