Bolt could add 400m record

Usain Bolt’s coach says the Jamaican could attempt to complete his dominance of world sprinting by targetting Michael Johnson’s 400 metres world record.

Bolt enjoyed a stunning Beijing Olympics this summer when he set world records for the 100m and 200m, as well as being a part of the Jamaican team who set a new mark for the 4x100m relay.

And his coach Glenn Mills told Radio Jamaica that he would not rule out the youngster making a tilt at Johnson’s 1999 one-lap record of 43.18, although not until 2010 at the earliest.

‘At this point in time in his career I don’t have a problem with him concentrating on the 100 and 200,’ Mills said.

‘Since he is not motivated to run the 400 as an event I am not going to pressure him so to do. But he could attempt it in 2010.’

Meanwhile, a biomechanist at Stanford University in the United States has predicted the men’s 100m world record could come down by a further fifth of a second in the future.

Professor Mark Denny looked at the speeds of male race winners through the years and concluded that men have not reached their top speeds at any distance. (Duh! That’s obvious. All records get broken eventually.)

Denny predicted the women’s 100 record which is 10.49, set by the late Florence Griffith-Joyner in 1988 could only be lowered to used 10.61 seconds in his study because of ‘compelling evidence that the 10.49 race was wind aided.’ He also should have added that it was probably drug assisted.

In the marathon, where Haile Gebrselassie holds the men’s record of 2 hours 03 minutes 59 seconds, Denny’s study says that time can be lowered by more than three minutes to 2:00:47. According to the research, the women’s record of 2:15:25 set by Paula Radcliffe could be trimmed to 2:14:97.
