Badminton smash is one of the most powerful and fastest techniques in racket sports. The purpose of this study was to analyze the grip force and pressure of a collegiate first-class badminton player while performing smash and jump smash movements. A grip pressure system (500Hz) and a high-speed digital camera (2000Hz) were simultaneously used to collect eighteen areas of grip force and pressure of the dominant hand, along with 2D kinematics motion images. The results revealed that the initial shuttle velocity of the jump smash was faster than that of the smash stroke. Additionally, the swing movement of the jump smash was faster than that of the smash. The maximum grip force and peak finger force point during the jump smash were greater compared to the smash. Furthermore, it was observed that the middle finger played a primary role when executing both the smash and jump smash strokes.
