Apart from genetics/talent, what other qualities do you see in Casey accomplishing that 6.59?.
Low bodyweight?.
Great elasticity/spring?.
Doesn't look to have great "strength" levels in the purest form of max strength.
Any thoughts?.
well, he doesn't "look strong from a physique sense", but either do the people who bend ridiculous level iron/pans/nails/etc.. either does stefan holm and many of those youtube dunkers etc..
i havn't seen him shirtless or nearly nude (speedo) but i imagine he wouldn't look weak.. i imagine he would look pretty solid/dense even though he is so light.
genetics is his #1 quality, he hasn't been studied so who knows, but i'm assuming it's completely optimal leverages/tendons for sprinting, very high percentage of type IIx fibers throughout his body, really incredible CNS, relative strength off the charts, etc.
he has to be crazy strong relative to his bodyweight, to perform the way he does.. there's just no other way to describe his power.. he's not purely reactive, that's for sure.. he looks very strong to me.. that type of acceleration & 'drop step VJ tuck jump' require a very high amount of raw power. if he was ALL tendon, his acceleration would be nowhere at the level it was.
he's very strong no doubt about it.
