World men sprint event development status research based on grey theory


Next Olympic Games prediction problem is always the hot pot that attracts correlation researchers’ attention. By SPSS mathematical statistics method, test and handle with previous Olympic Games men 100m first performance, establish grey GM(1, 1) prediction model, prediction result is 9.71s, and through testing on residual value and ultimate ratio deviation value, it gets that the prediction result is relative correct. In research, it combines with actual, select recent several sessions’ performance data to make prediction again, result is 9.49s, comparing with first prediction result, and it is more accurate and conforms to practice. Therefore, next session Olympic Games men 100m performance is within the range 9.49s-9.71s. The model has the advantages of small relative errors from prediction results and high precise.
