How to export part of a Database

So our xenforo site is a sports site associatied with a university. A Student from the university would like to use all the posts from our football (American football) in a research paper.

I know all the board posts are located in xf_posts but can I just pull just the post or do I need to xport the whole thing. I really would like to just send him the post from football with out user names.
