Bolt will compete against Britons James Dasaolu and Dwain Chambers in an eight-man lineup where every starter has broken the 10-second barrier.

John Barrow, Professor of Mathematical Sciences at Cambridge University, last year carried out his own research on the athlete and claimed Bolt could slash another 0.13 of a second off his world record, if he improved his reaction time at the start and ran in the best wind conditions possible.

Oleksiy Torokhtiy The Ukrainian weightlifter won gold in London 2012 in the 105kg heavyweight category.

According to the model, Bolt’s time of 9.58 seconds was achieved by reaching a terminal velocity of 12.2 metres per second, around a quarter of that achieved by a skydiver in a belly-to-earth freefall position, and exerting an average force of 815.8 newtons, close to the force of a knockout punch from a heavyweight boxer.

By taking into account the altitude of the Berlin track, the temperature at the time of the race and the cross-section of Bolt himself, researchers from the National Autonomous University of Mexico calculated that he had a drag coefficient of 1.2, which is less aerodynamic than the average human.

His winning clean and jerk would have consisted of 2,200-plus watts for the first movement and an enormous 3,700-plus watts output for the second movement lifting three times his bodyweight above his head.
