GM(1,1) Model of International and National Records in Women's 400 m Hurdling and Calculation |
| |
| Abstract: | By literature and gray model in the systematic gray theory, the calculable gray model of international and national records in women's 400 m hurdling has been set up and tested. The results reveal that the precision of the calculable model is at the first rank, which could be used to present the systematic rule of athletes' performance. |
