Strange Raymond Stewart comment about sprint technique???

about yohan blake’s performance at the world

‘’He is still young so he still has a lot left in him to do well and run much faster, getting him much stronger, he will for sure run faster,

the kid has great lift, high knees, which you need in sprinting, the higher the knee lift, the more force coming back down and more bounce getting back off the ground, and his arms control his body movements and he his in control upper body wise, confidence level is high so that is what will make him a competitor and to run faster, he only needs to be stronger and the rest his history, everything is in place now."

in theory and to a point but if you get too high then you actually end up losing hip height.

More like the greater the force of the ground results in a greater knee lift…

Is this a chicken and egg situation
