What is the fastest 100m ran by a caucasion person?

Lol, I agree. And you know we’ll both roll our eyes, when in ten years time, there will be a big “break thru”, when teachers tell us that exercize can stimulate the brain because the mind and the body are linked, and so therefor; P.E should be done. (for 10 minutes once a weak.)

As a side note, the sumo wrestlers increase their girth for three reasons:
A) More weight (obvious)
B) Harder for the opponent to get their arms around the mid-section.
C) Because a greater girth slightly lowers the center of mass, by pulling it downwards. This they believe, makes it harder for them to be toppled or thrown or pushed by their opponent.
(Amazing that a small oriental nation can produce such super sized athletes, to keep it a tad relevent to the thread.)

Despite the importance of the hip and leg muscles, many sprinters are ‘top heavy’ compared to to other people, in terms of girth. In reality, they have an astheticly pleasing physique and are the fastest of all athletes, so not realy top heavy in terms of functionality.
Look how thin Shawn Crawfords’ calves are, and look how developed his torso is. I don’t think that level of developement is necessary in upper body of sprinter, but it doesn’t seem to hurt him. Asafa Powell and Usain Bolt both have broad shoulders.
