Japanese anime run?

Question

You know how characters run in Japanese animes? With their arms pulled behind their backs? Do people really do this in real life? What are the benefits? I know aerodynamic... but is it practical?

Thanks

Answer 1

No. They don't. Don't do it.

/question

Answer 2

arms pulled behind their back so they dont have to draw the arms moving :) LOL

and running WITH ur arm helps u speed up, much better and helps ur balance. dont run with ur arm back, wat if u trip? =p

Answer 3

i guess its good if youre running really fast... aerodynamic as you said and maybe less tiresome because you dont use your arms?... just a guess though...  tried it once but i didnt really notice a difference lol.... could just be a culture thing...  

or maybe its a ninja thing (less movement less sound?)

enough speculation ^^ take care!
