Re: Movie 7
No it's not jabbament, Blueno thought it was because he couldn't comprehend it. Luffy learned to move as quickly as soru, by using the same mechanics in a different way (kicking the ground 10 times),
However Gear 2 is a seperate ability, it has to do with his Gomu Gomu ability, not Soru..
He explains gear 2 to Lucci in ch 420
[Spoilers]
Apparently he uses his legs as a pump to increase the blood pressure and blood movement inside of his body. His heart pumps out more blood faster, thus strengthening him and allowing him to move more quickly.
A normal human being would not be able to withstand this kind of ability since his internal organs would not only give up due to the increased blood pressure, but also since they are not rubber they can not expand and contract, thus would possibly explode.[/spoilers]
