Is it natural to say "xxx sports contain a, b, ..."

Question

According to Cambridge Dictionary, "include" means

to contain something as a part of something else, or to make something part of something else

while "contain" means

to have something inside or include something as a part

According to an ELL post

The distinction between 'includes' and 'contains' is a bit more subtle. 'Contains' is used when there is something else that is doing the containing. The box is a container, and contains the hats. You would not, generally, say that the box includes the hats. Inside the box is a set of objects, and that set (which 'contents' refers to) includes (and consists of) the hats.

Common combat sports include mixed martial arts, boxing ...

Is it still natural if I substitute "contain" for "include"?

Common combat sports contain mixed martial arts, boxing ...

Answer 1

“X contains Y” requires thinking of X as a container. Not all containers need to be physical, but I don’t think of “combat sports” as even a virtual container. They are using it to mean a list of sports and then give examples “included” in that list. Lists are not containers.

Answer 2

“Includes” actually works much better. “Contains” almost makes it seem as if they are saying combat sports are a mixture of the different specific disciplines it mentions. “Includes” is more clearly showing that “combat sports” is a category and that boxing, wrestling, kick boxing, etc. are examples of sports in that category.
