A short distance is a general term for the game which runs short distance in track and field (to 400 m). Official events are 100m, 200m, and 400m. In unofficial events, there are 50 m, 300 m, etc. It is decided that the method of a start will be a crouching start. Moreover, a runner uses a starting block.
Especially in 100m and 200m, runners can run very fast when a fair wind is strong. So a fair wind exceeds 2 m/s, it is considered that the record is a wind-aided record. (That is, it does not become an official time.)
A 100-m world record is 9"58 which Usain Bolt established in 2009. When this record is changed to speed, it is an average of 37 km/h. In the Olympic Games, the title "the man of the human-beings fastest" is conferred on the boy's 100m champion. In track and field, 100 m is very popular and is a star game.
In case of 200m ,world record is 19"19 which Usain Bolt established ,too.At the Olympic Games, 200m is an event from the Paris Olympic Games in 1900.Unlike 100m, even if a frame and muscular power are inferior to other runners , it can cover with the way and technology of running.
400m is the most hardest event in short distance block. Distance of 400 m is medically made into "distance of the limit that man can run the whole distance by sprint", therefore a race will become very severe.
The world record is 43"18 which Michael Duane Johnson established in 1999.Incidentally, the Japanese runner who ran 400 m on the level of 44 seconds has Susumu Takano.
