WORLD RECORDS BY AGE
Rules
|
Reference book: ATFS Annuals.
|
|
|
1. Only performances good for the Olympics can be records
by age.
|
Olympic Qualifying Standards |
|
2. Up to the year 2000, only outdoor results were valid
for the Olympics. Starting from 2001 both indoor and outdoor marks are
good for the Olympics. So I consider indoor marks from 2001 on.
|
|
|
3. Olympic Standards' duration: four years (from the year
before the Olympics to the second year after).
|
1983-1987; 2003-2006 |
|
4. Only the best mark per year for each age is considered.
|
|
|
5. My research starts from - at least - the best result
before 1977.
|
|
|
6. Automatic timing before 1972 was unofficial, consequently
I don't admit electric results before 1972.
|
Application of IAAF's 0.24 seconds rule |
|
7. Marks subsequent to drugs disqualification and all
marks made by life-banned athletes are excluded.
|
Drug Bans |

8. Chinese Games results are not included.

1993 Beijing; 1997 Shanghai;2001 Ghuangzhou. |
