【Abstract】 The variation method is an effective method to study the functional extreme value. It is widely used in many fields. The main discussion here is the application of the variation method in the sprinters sprint model. First,make a statement about the athlete sprint problem. Secondly,the main mathematical methods involved in the establishment of the model are analyzed. Then,according to the speed and momentum,the dash process is divided into two stages. On the basis of the assumption of some variables,the variation method is used to discuss the sprint speed and running distance of the athletes in two stages,and the results of the model are obtained.更多还原
