Bas Rutten did it this time! A while ago Sport Science they tested a Muay Tai knee strike ( which was more powerful then the Karate and Kung Fu kicks). The numbers were off the charts. It was equivalent to a 35 mph car crash and pushed the chest in about 1.5 in. Yesterday on Sports Science Bas Rutten gave a kick so hard that the guy that was giving the test made him do it again because the numbers were too high. Bas Rutten pushed the chest in 2.7 in(and created heart trauma) with a classic round house shin kick. Its proves the MMA kick is superior.
