Methods for Biomechanical Analysis of Sports Techniques

Biomechanical analysis of the sports technique is an important part of scientific researches on competitive sports and national fitness. The main idea of biomechanical analysis of the sports technique is goal-oriented, model-based, and reasonable in adopting data analysis methods. In view of the actual needs of athletic sports technique analysis and diagnosis, this research, based on a case study of athletic and swimming events, introduces the steps to establish the sports technique analysis model and data analysis methods with the goal of improving sports performance, and puts forward the problems that should be emphasized in condcting biomechanical analysis of sports techniques, so as to offer a reference for the research and practice of sports biomechanics, and provide technical assistance for sports training more accurately and effectively.
