Scrap's kinitec linking of a ko punch

[jms]

Cool video! I wonder how they make that!

Yes it is I'm glad that I found it! Remember Scrap's second principal that the lead foot acts as the break. Look closely again how the back leg moves forwards after the punch. The lead foot stops the body's weight from falling forward.

I don't believe that's right. Scrap says the heels act as the break. Not the lead foot, but either of the heels.

Also the way the lead leg is animated is wrong in that video. The knee is locked which is no good, too much leaning. The lead knee needs to bend too to keep the weight in the right place. Also way too much sideways leaning, whoever animated that make some pretty big mistakes.

Please don't start with national geographic conspiracies their at least a hundred years old, with all their money they can afford to make a video. I'll be up all night pondering as to why national geographic was lazy and callous. National geographic says that this is the most powerful punch, what we need to solve for is. Is that punch rotational or horizontal?

What are you on about? Doing a bad job doesn't imply a conspiracy. Isn't that clip from that sport science show anyway? It's notorious for shoddy science and outrageous comparisons (this guy hits as hard as a freight train traveling downhill and 300 miles an hour, and produces enough power to run your house!!!). The animation of the lead leg and the extreme leaning to the left is straight up wrong, that's like day 1 how to throw a cross stuff. Any decent coach would fix that immediately, and even the guy demonstrating wasn't punching like that.

There are several components to the trajectory of the punch.
