I saw this yesterday over at the Scientific American.
Meredith Miller, the high performance director of USA Taekwondo, is trying to clean things up by developing statistics for the sport, and also a better understanding of the “magnetic socks” integral to the martial art’s electronic scoring system.
Through the study of statistics they learned this:
It’s called a cut kick, in which a fighter pushes the opponent with the bottom of the foot. The research showed that executing a cut kick by leading with the ball of the foot was not very successful, but using the heel scored points 90 percent of the time.
