Human VS Cheetah?

A few days ago I stumbled upon an interesting article about marathon record holing runner Usain Bolt.  Many questioned how many more sprinters will it take to break a sub 2 hour marathon time?  Conclusions led to possibly one of the most bizarre comparisons in exercise science today, sprinting limits between humans and cheetah's.  According to experts, humans have quite a bit of room for possible improvement.

Scientific expert Peter Weyand of Rice University explains that humans could possibly run a 100 meter as fast as a cheetah.  Humans have the same muscles, tendons, and bone structure as do cheetah's.  The only debatable information now is that humans run upright and have 2 legs, opposed to cheetah's who have 4 legs and run more parallel to the ground. 

I thought that this was a very interesting article for all of the KPE students, here is the link
