Abstract

Have a connection with speed; track and field events in track and field sports, the most can reflect the speed of the project is the dash. This article through studies involved in the 100m sprint project dynamics, development trend of sprinters and impact performance of physical quality, establish the gray prediction GM (1, 1) model, get predict expressions of men's and women's 100m sprint. Using the Matlab software to analysis the factors that affect performance results in and mobilization, get motor skills are the main factors influencing the performance athletes.
