Llewellyn Starks, that happend during NY competition in 1992, winner was C. Lewis 872cm (+2.2). He broke his shin during takeoff! 
Came back alright to work for Nike and got in a punch-up with Gatlinās masseur!
How didnāt he have a massive leg infection after landing on the sand with his bone sticking out?? :eek:
BTW, any news about Gatlin? His preparation?
Ouch! How can something like that heal?!
imagine the forces created for this to happen! Could the same forces be created when running the 100m too Fast? Imagine falling at over 40klm hr with a broken leg! ouch
Supposedly 10 x bodyweight at takeoff for a LJ
About 4 x bodyweight for a sprint impulse, but could be less. Iāve heard different estimations (down to as little as 1-1/2 x bodyweight for sprint impulse in the upright position)
I guess bolt has very strong lower abs, good hip mobility, and strong posterior chain to acheive this position.

Skip to 11:34 and watch Simeonās left leg after his drive, it seems to turn outwards before each foot strike, causing him to drift to the left of his lane, but then after he dips his leg seems to be going straight all the way through again. Whatās going on here!?
Heās always ran like thisā¦granted over the last 2 years its gotten more pronoucedā¦Its only now cos heās in the worlds limelight that it has been noticed and scruntinsed by loads of watchers. Iāve never seen it as bad as this thoughā¦his form went and he tried to muscle it out. It looked like he was limping while running. He wasnt getting that massive extension of the front of the left leg which he normally does or any height of the track in say comparison to how he looked during the indoors championships (almost looks like he bounds down the track)
do these people have therapists?
