Japanese ninja 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

i dont think people actually do it (i havnt really done much ninjitsu) but it would put ur center of balance i litle bit furtheur back so u can lean further forward so keep lower. you would also minimize the sounf you make because you are not moving your arms.  thats the only reasons i can think of to do it.

Answer 2

There are a number of running and stepping skills in traditional Ninjutsu the only reason to run with your hand behind you would be to steady a sword or something hanging from your back. Other than that its a cartoon thing.
