Keep in mind that ALL of Captain's training was done by the best that the U.S. could possibly provide from day ONE. If any john doe is trained for a decade and a half by masters of his discipline, whether it be physics, sports, chess, or whatever, he's going to be pretty damn good.People who are at their absolute oldest in their mid 30s? definitely. Batman didn't begin training until his mid to late teens. how good do you suppose he is again?
I don't know where you're getting "more well versed in global travels" since the leader of the avengers, sole super soldier for the US government and operative of S.H.I.E.L.D. would arguably have some pretty extensive resources and just MIGHT be fairly well traveled.
Firstly between 1940-45 he'd be kinda busy fighting Nazi's. He wouldn't have time to learn martial arts. Then he'd come back very tired or even injured. So how would he be studying. and also I doubt that they'd be able to bring martial arts experts to the front or go back home when Nazi's would be firing on them. Also considering for many years Shiva spent her life studying with martial arts masters and then killing them in one on one HtH combat when she learned everything she needed from them I'd say that she'd be way more fight-experienced and better martial arts wise.
