Saw it on fightscience recently where the impact of Bas Rutten's kick was measured to be harder than a 35 mhp car crash. The test was done on a specially designed dummy. Bass pushed in the ribcage of the dummy almost 3 inches, whereas on a person it would break the ribcage and severely damage the heart and internal organs if not kill the person.
For one I find this to be amazing that Bas still has that much power and speed at age 42. He probably kicks just as hard as CroCop (just not as flexibly). Now I realize why warpath tapped out to his leg kicks.
Sorry if it's been posted. Did a search and couldn't find anything. If anyone hasn't seen this episode of fightscience I highly recommend it. The show features Tito, Randy, Bas and Dean Lister. It really portrays the mma in a positive aspect. National Geographic is a popular channel so I hope it makes people understand and respect the sport a little more.
