Women's 400 metres world record progression

From Wikipedia, the free encyclopedia

The first world record in the 400 m for women (athletics) was recognized by the International Amateur Athletics Federation, now known as the World Athletics, in 1957.

To June 21, 2009, the IAAF has ratified 27 world records in the event. Their 2009 record progression list, however, lists 26 records.[1]

Record progression from 1975[edit]

From 1975, the IAAF accepted separate automatically electronically timed records for events up to 400 metres. Starting January 1, 1977, the IAAF required fully automatic timing to the hundredth of a second for these events.[1]

Riitta Salin's 50.14 from 1974 was the fastest recorded result to that time.
