Re: High kicking
I have seen some people who study Tae Kwon Do who can throw a kick to the head about as fast as an average person could throw a punch, and with a lot more power. I would never throw a kick higher than about groin level because it just doesn't work for me... I feel unbalanced and definitely not centred when I do it. But for those that train for high kicks they seem to have no problems.
There was a show on discovery channel not long ago where some scientists compared different styles of MA, the Tae Kwon Do spinning back kick delevered over 1500 pounds of force to the crash test dummy and was also put forward as being one of the fastest martial arts.
