Apply GM(h,N) in the influence factor analysis of 300 m Man´s Race

Push pace and push frequency are the two important factors, which constitute the speed skating. This article was based on 25^th National Jhong-Jheng Cup Speed Skating Tournament´s 300 m men´s race and time trials competitors as research objects. The main purpose of this paper is to explore the effect of push pace and push frequency toward competition performance at time trial item of 300 m men´s speed skating race. First of all, the entire competition process was recorded, and took down related data. Then, the data was analyzed the weighting by the GM(h,N) in grey system theory. During the analysis, the data was also calculated by using Matlab toolbox, we found out the most important factor which influences the performance of 300 m men´s speed skating is the push race. Finally, in order to provide further research and reference of training for coaches and athletes, some suggestions are proposed according to the research result.
