  • Objective: To analyse the kinematic characteristics of smash in badminton and to explore the key factors affecting the effectiveness. Method: Forty badminton athletes at national level were selected from a university, and each of them performed 10 smashes in situ. They all wore sensors equipped with motion capture system, which are designed to collect their three-dimensional coordinate movement trajectories. The data then could be used to calculate the joint angular velocities, respectively of the knee, hip, shoulder, elbow and wrist. The calculation of peak angular velocities and the time lag naturally render the descriptive statistics of mean and standard deviation. Results: The transmission sequence of the badminton smash action is knee→hip→shoulder→elbow→wrist, and the joint torsion speed gradually increases during this process with the joint torsion speed increasing gradually with the transmission of the dynamic chain. The shoulder joint forward flexion contributes the most, the elbow joint speed should not be too fast, otherwise it will lead to the blockage of speed transmission, and the wrist joint rotation and deviation contribute more. The acceleration of the racket hand and the position of the centre of gravity are strongly correlated. Conclusion: The power source of the badminton smash action comes from the ankle, upper limb joints contributed significantly more than lower limb joints. A good position of gravity is beneficial for the player to start and move quickly and thus get more active opportunities to hit the ball.
