Abstract
In this research, in order to consider on the performance analysis of the top sprinters in the regional rankings regarding to the 100m sprint and the construction of a support structure for the future. Analysis targets are totally 660 data available which were ranked within 10th in each year from 1955 to 2020. As a result, each time was 11.59 ± 0.25s (1955s), 10.90 ± 0.21s(1990s), 10.72 ± 0.12s (2015s). However, this turning point of performances was appeared in 1990-1995 compared with 1955-1990. Especially, posterior performances were no significant difference, and then it was cleared that athletes performances were not improved since 1995. Ranked athletes were consisted almost high school students(55.4％，1955-1990 年), but it was changed to university students(50.8%) for latest 26 years. For the reason, it can be said the issue is that the period of performance maintenance is as short as 3 to 4 years. It is necessary to construct a support structure so that adult athletes can continue to join every competition in the future.
