Application of Multivariable Mathematical Statistical Analysis in Safety Protection of Marathon

Xinbao Wang, Xuemin Zhao

Abstract



Multivariable mathematical statistical analysis is a statistical discipline that studies interdependent relations and inherent statistical regularity among multiple random variables. As an official competition item in the Olympic Games, due to long distance, long duration and great energy consumption, marathon has extremely high requirements of human body, and could easily cause various sports injuries. This paper uses multivariable mathematical statistical method, principal component analysis and factor analysis comprehensively considers internal and external factors that cause internal injuries, and studies the safety of marathon, in order to propose some valuable comments and suggestions for safety protection of marathon athletes.The result shows that Multivariable mathematical statistical analysis (comprize principal component analysis and factor analysis) should be applied in safety protection of marathon.

Keywords
