Hier mal eine ganz interessante Seite, u.a. mit dem Split von Bolts Weltrekord

The magic of this performance, however, is not so much in the spectacular top speed between 50m and 80m, but rather that Bolt could maintain his speed for so long.
Remember, a sprinter typically hits peak somewhere between 50 and 60m, but then slows progressively. Bolt's huge victory was created thanks to his incredible 50m stint between 40m and 90m, where he never dropped below 42km/hour.
Even if he had maintained his speed for the final 20m (which is unlikely - he'd probably have dropped off slightly), he would have run 0.09 seconds faster. This would give him a 9.60 second time, which is incredible. More likely, he'd have slowed anyway (as all sprinters do), so I'd guess that his celebrations probably denied him about 0.05s and a time of 9.64s.
