Not strictly related to Bolt but....
Beyond Usain Bolt: can the world's fast men get faster still? How many more barriers can sprinters break and is there a human speed limit?
...........So what about changing our muscle fibre composition to upgrade to more fast- twitch fibres? Or, as one scientist put it, just splice some hummingbird genes into our own DNA? "It would certainly make us radically faster," says SMU's Peter Weyand. "If somebody manages the technical trick of having really fast animal fibres introduced, then all bets are off. Really crazy things would happen."Another possibility is that our own DNA could be manipulated to code for the fast-type muscle fibres, and the science for that, say the experts, is already in place – experiments have taken place in southern California and proved that it works. "That's the whole gene doping scenario," says Weyand, "and that's probably not very far away."
So at the Olympic Games of 2036 – 100 years after Jesse Owens – we could be witnessing some extraordinary times if the scientists get their way. It may sound like a bad plot for a kids' cartoon but if the history of the fastest men on earth has taught us anything, then it's always to expect the unexpected.http://www.guardian.co.uk/sport/2011/no ... nters-100m
