Three-Dimensional Image Analysis of the Movement Characteristics of Nunchakus Kick Technique

Standard taekwondo turning kick technique motions are very important resources in teaching, training and further research in the future. In this paper, it is mainly the research and design on inherent regularity of taekwondo turning kick technique motion. Firstly, a turning kick technology motion image collection plan based on three-dimensional image is proposed and the collected motion images are processed to get kinematics parameters (velocity, displacement, etc.) of motion. Then testing apparatus of combating event group is utilized to directly obtain kinetic parameters (force, torque, momentum, etc). Finally, through MATLAB these parameters are processed secondly, thus obtaining the changing rules of parameters in turning kick technology motion. The results show that the scientific and rational muscle force order has ensured good hitting effect, the intensity and range of upper limb swing related to the waist and hips also affects the hitting effect, meanwhile the strength, speed and explosive force have significant effect on hitting effect.
