Is that the Taekwon-do Ive seen in the Olympics?
No, there are different styles of Taekwon-do, the most popular two are ITF and WTF. ITF tends to concentrate more on technical, traditional and self defence training and WTF on the sport sparring side. ITF does have a sport side as well for those that want it, but ITF Style sparring is different from WTF. Please see the Traditional section for more information.
