Cool Duck, we've seen the video a million times, you don't know Earl1972 do you!!
Besides, two totally different scenarios, not even close.
Ok, after all, I agree with you. When I heard about the Levrone vs Chambers race, my first thought was "That is a highly dangerous project". Being very heavy and at the same time very strong in only some of the muscles involved in running (quads, hams, glutes), but probably not in the very heavily involved hip-flexors, is a recipe for injuries. Also, explosive movement with lots of body-momentum in a body not trained for such strain, not safe at all.
I think I've heard several stories about patella ruptures and quad tears in bodybuilder doing everyday activities such as small jumps and such. Also, I think it ws mentioned here on getbig that Lou Ferrigno tore his achilles while playing football.
