To understand the paradox, the researchers set up a computer model of a sprinter’s push-off. The simulation revealed that despite providing a mechanical disadvantage, the short lever arm of a sprinter’s heel actually produced more force than the longer lever arm of a non-sprinter. Funny how as soon as you discover something, your computer simulations miraculously start to predict it.
