As the world's best athletes descend on London to take part in the Olympic Anniversary Games, a group of researchers from Mexico has provided an insight into the physics of one of the greatest athletic performances of all time.

In a new paper published last week in IOP Publishing's European Journal of Physics, the researchers have put forward a mathematical model that accurately depicts the truly extraordinary feats of Usain Bolt during his 100 metre world record sprint at the 2009 World Championships in Berlin.

According to the researchers' model, Bolt's time of 9.58 seconds - which is still the world record - was achieved by reaching a terminal velocity of 12.2 metres per second and exerting an average force of 815.8 newtons.

What was truly amazing about his performance, however, was the amount of power and energy that Bolt had to exert to overcome the effects of drag caused by air resistance, which were exacerbated by Bolt's huge 6ft 5in frame.
