DAEGU, South Korea (CMC):
Usain Bolt will have to learn quickly how to deal with the nerves that led to his false-start disqualification in the final of the 100 metres at the World Championships.
Track & field's world governing body said it had no plans to change the rule before the Olympics next year in London, despite the disqualification of the world sprint king and the sport's biggest star.
IAAF President Lamine Diack said no official at yesterday's council meeting raised the issue about the false-start rule.
"We will not come back to the issue," he said. "Bolt had a false start, but that is not going to make us change."
The 'one-false-start-and-you-are-out' rule has been heavily criticised from last year when it came into power and even more strident reviews following Bolt's stunning disqualification two Sundays ago.
Previous false-start rules allowed runners room for error, but too many of them led to delays to event schedules, and grumpy telecasters in particular.
Bolt was one of handful of high-profile runners that suffered false-start disqualifications. The others were Olympic and former World 400 champion Christine Ohuruogu, as well as fellow Briton and former European 100 champion Dwain Chambers.
