Truly amazing forces on one's limbs . Should these runners have to be insured if they go on the road?


"If one considers that elite sprinters can apply peak forces of 800 to 1,000 pounds with a single limb during each sprinting step, it's easy to believe that runners are probably operating at or near the force limits of their muscles and limbs," he said. "However, our new data clearly show that this is not the case.

the critical biological limit is imposed by time -- specifically, the very brief periods of time available to apply force to the ground while sprinting. In elite sprinters, foot-ground contact times are less than one-tenth of one second, and peak ground forces occur within less than one-twentieth of one second of the first instant of foot-ground contact.


Human running speeds of 35 to 40 mph may be biologically possible (http://www.sciencedaily.com/releases/2010/01/100122102843.htm)

Will they be prosecuted for exceeding the speed limit in a built up area?

And this is news ? Obviously never enjoyed the Goat based cuisine in Africa, or perhaps the local delight of scud* !


(*scud - beer and sour milk mixed together)

So, if we extrapolate the conveyor belt flight dilemma & correlate it with this news, we prove conclusively, that a human being cannot fly...ergo, the aircraft will not take off either!

Seems slow to me....ever seen what happens when someone drops a live grenade by accident? I swear I smelled burning rubber from the boots spinning out on the concrete floor as the guys headed for other places while approaching the speed of light!:E

I dunno, the last time I made a "ringburn" chilli and then went and had some Guinness I swear that my feet did not touch the ground.


Ergo, I was flying and so would the aircraft

And the belt would move in the same direction :suspect:
