Since Liu Xiang won the 28th Olympic Men’s 110m hurdles champion, Chinese athletes’ hurdle technique research has become a hot topic. In this paper, we focus on Chinese top 110m hurdle athletes’ special features, by using multiple linear regression to analyze the correlation between Chinese top 110m hurdle athletes’ performance and 4 factors (the number of 98% speed striding hurdles, the whole 10 hurdles step soaring time, the whole 110m hurdles’ three pace running time, the number of striding hurdles before the Max speed turn down). Further on, we use grey relational analysis to find out which factor is dominant in the performance.
