In an attempt to reveal the characteristics of the boundary age of each training stage and the number of years for the total training process and each stage,the basic circumstances of the whole triningprocess of 379 Chinese p1ayers participating in the 23rd and the 24th Olympic Games were investigated. The results indicated that the total training years for Chinese Olympic players generally ranged from 7 to 14, obviously characterized by group event and specific event. The fuzzy ratio of the number of years of various training stages was 3: 4: 3 and the boundary age of training stages was lower for the event of gymnastics, diving and swimming, and higher for the event of shooting and cyclin.The boundary age model and fuzzy number of years for each training stage presented in this study may provide an effective, objective criteria for analysing the time characteristics of the selection, training and management of the Olympic players.

The results indicated that the total training years for Chinese Olympic players generally ranged from 7 to 14, 30% of the groups characterized by group event and specific event.
