VIdeo - Science on the effect that the KO-out had on Pacquiao "Spanish"

[MexicanBoxing1]

Here is a video where ESPN Deportes explain how strong was the punch that Marquez landed on Pacquiao which might be similar to a hammer of 1300 pounds of strength, incredible. Please some one translate, I am not very good at English, sorry.
