Research on Protection Property of Running Sportswear Fabrics Based on 3-D Motion Capture System

The running sport was regarded as the research subject in the topic and the sports biomechanics was applied to the research of the sport protective apparel fabric with the spring-mass model. And the running movement was simplified and the mechanics model between the human body and the fabric, namely the running protective model, was established. On the basis of the model, elasticity and thickness of fabric were further changed to verify their impact on the protection property of the human joints, taking advantage of the 3-D motion capture system to acquire the data of the movement trajectory. The result shows that the changing rate of momentum can be used as the parameter evaluating the protective performance from the protective model in running movement. The change of the fabric elasticity and thickness has some influence on the evaluating parameter of skeleton. Moreover, the effect of the fabric thickness is more obvious and representative of the protective performance of joints, which could serve as the basis that designs and develops the running protective sportswear.
