Abstract
In order to improve the level of athletes, modern scientific and technological means can be used to understand the characteristics and rules of movement. This study mainly analyzed the whip leg technique of Sanda athletes. Taking ten athletes as an example, the kinematics and surface electromyography (sEMG) data of them were measured, calculated and sorted out when they were doing the action of round kick. The results showed that the movement completion time of the first-level athletes was shorter, 0.34 ± 0.33 s. In the stage of turning hip and hitting, the angle of hip joint increased significantly. In the stage of turning hip, there was a significant difference in the angle of hip joint between different levels of athletes (p < 0.05), and there was no significant difference in other kinematics characteristics. In the aspect of sEMG, the duration of muscle discharge of the first-level athletes was shorter, but there was no significant difference in integrated electromyogram (IEMG) and root mean square (RMS). The experimental results reveal the importance of hip joint in the course of round kick and provide some theoretical bases for improving the level of athletes and carrying out targeted training.
