ABSTRACT
The Olympics is the biggest event in the international sports meeting. The athletes getting medals in the Olympic Games can not only demonstrate personal style, but also win the honor for their motherland. Thus each country's cultivation of athletes has a strong force. In order to make their own country's athletes reach the world's top level, it is not enough just to achieve the predecessors' performance. Since, each game may have a new breakthrough, sports scores forecast becomes a demand of sports development strategy and athletes training methods. This study uses the champion performance data of men's 400m freestyle in recent 10 Olympic Games, establishes a single sequence first-order linear dynamic model as a predictive model and conducts single sequence residuals identify forecast using the differential dynamic modeling method. It predicts the champion score of men's 400 m freestyle in the 31st Olympic Games is 220.16 sec; the score shows that the achievements of the 31st champion will not break the record, but close to the last record in the Olympic Games. This study provides a reference for the selection and training of next Olympics athletes in various countries around the world and lays a foundation for the relevant scientific research.
