Abstract

In 21st century, Chinese men 110m hurdle suddenly raised analysis and research on hurdle performance and techniques have already become a hot topic. Carry out researching on 4 factors significance that affects hurdle performance, utilizes multiple linear regression, analyzes Liu Xiang 110m hurdle total performance significance in stages from start to first hurdle, hurdle step soaring, three-pace running, the last exertion, then applies SPSS software in implementing unknown parameters estimation and significance testing. To define 4 factors correlations with total performance, establishes grey relational degree model, gets that techniques in last exertion, from start to first hurdle are Liu Xiang strong points, and techniques in three-pace run, hurdle step soaring are his weak points.
