Yes, in the comics she has been gifted with a Russian variant of the Super-Soldier-Serum. It has metabolized and permanently enhanced all of her bodily functions to beyond the peak of human potential like with Captain America. She is another example of what a scientist in the Marvel universe described this potential as being "the next step in human evolution," while still remaining completely human. None of their abilities would weaken. Both are intelligent, strong, fast, agile, and durable as possible for humans being to be without being considered superhuman. Both will remain permanently young and have powerful healing factors. One downside is that they cannot have children with normal people and only with ones of the serum like each other (and also mutants & Gods possibly). Know all that?
