A while back they had this show on some chanel, might have been fox sports, the science of sports or something. On one of the shows they measured how much pounds of presure per foot or something each punch created, well basically the boxers punch won out with something like a 1000+ lbs, equal to a karate kick. The most devestating however was some crazy thai boxing move that was the same as being in a car wreck at 40 miles an hour....so but jeah I guess boxing punch beats out a kung fu one.
