Hurdle technique analysis and application of the 110m hurdle based on human body motion mechanics

摘要

Under the premise of the same hurdle velocity, based on human body motion mechanics, this study conducts force and motion analysis of the human body at three links: hurdle run transforms to crossing, soar and touchdown of the hurdle transforms to hurdle run. Besides, this study also analyses the impact of each link???s responding time on the hurdle crossing velocity. With human body motion mechanics, such a natural science as a means of research, this study confirms the existing techniques and obtains the relevant factors to improve the hurdle velocity through theoretical analysis, in order to provide a theoretical basis for the 110m hurdler???s techniques.
