Watch this head-stabilized video of a champion hurdler

Grant Holloway is the world champion in the 110 meter hurdles. Watch the fascinating video above in which his head is digitally stabilized. From Kottke:

In this view, you can clearly see how expert hurdlers don't jump their whole bodies over the hurdle (like Super Mario or something) it's more that they just bring their lower bodies up over the hurdles while their heads & shoulders remain more or less the same height from the ground.
