The 2nd 100m is faster than the first, or at least that is how johnson set the 19.32s. However i doubt that Bolt will do anything like 9.7 over the first 100m as he will probably fade on the straight.
As for the question, if he is at it they probably all are at it...
Its a fair point, never say never etc etc. But Im sure I read somewhere that with human reaction time and all that jazz, a scientist came out and said that it was humanly impossible to break 9.5 seconds.
Dont get me wrong, the record will be broken and broken soon. But to go down to anywhere near what some above have been saying I think is highly highly unlikely.
Is he taking any banned substances. No.
But he's taking something. They all are.
The line has been drawn.
Illegal | Allowed
HAh yeah.
Ben Johnson's eyes were popping out of his skull.
Lol...what a bunch of haters.
Funny how no one's asked if 7-gold-medals-Phelps is clean.
You can see this in the West Indies and the US, because a lot of black people were descended from slaves. They were bred to be big and strong each generation for 300 years, thus ensuring the continuity of certain genes that influenced this area of their physiology.
In West Africa (and around the world, even), despite being the same people these particular genes are not as much in abundance, thus compared to the population size countries like Nigeria and Ghana produce less top class sprinters.
