Sports Biomechanics Analysis Of Taekwondo Side Kick Technology

Research purposeAfter the emergence of Taekwondo electronic protective gear,the use rate and scoring rate of lateral kicking related techniques and tactics have been improved.But the use of the technology is still immature,there is a lot of room for improvement.By analyzing the lateral kicking action in the image,this paper analyzes the characteristics of the action and the technical elements,and puts forward his own views on how to use the side kicking technique reasonably in the competition,how to carry out the lateral kicking technical training,and provides theoretical guidance for helping Taekwondo athletes to improve the technology and then improve the performance in the competition.Research techniqueThis paper uses the method of literature to provide a reference for the research design and conception of this thesis,to provide materials for further research and analysis by means of image measurement,to clarify the feasibility and innovation points of the research through expert interview method,and to provide directional guidance for the main research points,and to measure the relevant kinematics parameters by experimental method,Provide reliable data for overall research.By means of mathematical statistics,the raw data are counted and processed,and the correlation analysis of various factors which may affect the effect of lateral kicking technique is carried out,which provides a basis for the research conclusion of this paper.Draw conclusions from the results and analysis he time of starting knee lifting and rotating hip retraction is shorter than that of kick,and the time used in each time stage of lateral kick is closely related to the whole completion time.The angular velocity of hip joint is closely related to the velocity of ankle joint.The faster the angular velocity of hip joint is,the faster the speed of ankle joint is,and the effect of hitting is limited by the flexibility of hip joint.The velocity changes of hip,knee and ankle of kick leg are: slow,acceleration,deceleration,slow;The displacement of X and Y axis was larger than that of Z axis,and the displacement of Z axis was smaller.There were differences in the displacement of X axis.Excellent athletes were more than ordinary athletes.Stability.
