I don't recall one directly linked to attacking, but as your character will be hit regularly the constant thumping or dodging to avoid a blow will likely drain your stamina to a degree. It also stands to reason that wielding a heavy weapon (heavy for your character, anyway) or a flail that must constantly be in motion might drain a bit of your stamina, but you'll need to ask an Obsidian employee about specifics.
Ah, you guys are discussing what-ifs. I thought I might have missed something official.
