For those of you who are unaware, the world athletics championships bronze medallist, Asafa Powell, has smashed his own world 100-m record by 0.03-s!

You can watch his world record 9.74-s run in the video below as well as the 9.78-s run he recorded at the same meet.

If you can cope with the cheesy music there’s some excellent race angles.

The most astonishing part of his 9.74-s run is the fact that he appears to ease down after 85 - 90-m.

I’m sure there’s a few sports scientists in the world, including me, interested in putting some force plates underneath Powell and recording the amount of force he puts into the ground!
