[Harry Potter] Do wizards have some form of wizard MMA?

Yes; we know dueling clubs aren't uncommon but quidditch seems to be the only popular sport; and some as interested in sports and dada as Harry would have probably taken note of it.

In the UK it appears they don't. Why should people hone their bodies when magic is enough? If you're in a situation where you don't have your wand against another wizard then you're screwed anyway. It's very unlikely that you'll both be without a wand and even so, wordless magic is still a thing. If you have to prepare to be in that predicament, then apparating is more efficient and practical.
