Yes. His senses, if nothing else, have been enhanced to superhuman levels. Everything else about him physically reads as "peak human" except, even if an Olympic level athlete trained throughout their entire prime, they'd never be able to do half the stuff that Cap and BP can do. Calling them peak human is really just a wink and a nod to the fact that writers want to portray them at the apex of what a human being can be without actually being superhuman.
