Sparring as we've seen can have a wider range of emphasis and definition. At the end of the day IMO, sparring is training free from pattern or drills with intent to make contact with the opponent. Injury is a risk but shouldn't be inevitable.
In the FMA world sparring gets even more confusing. Lots of people consider non padded free flow drills sparring, without intent to hit the head FMA is a completely different animal. IMO FMA sparring should require at least head gear, I'd almost hesitate to consider it sparring other wise but I'm biased. You can body spar and do all kinds of variations but "sparring" without any kind of specification is what I'm getting at. I've seen quite a bit of non padded FMA sparring where no one seems to take a head shot yet the fighters claim to be going all out. But what seems to happen is a game of trying to show "I got you" without actually hitting and there are often tough calls where one wonders if the hit really would have landed.
Completely different note here, but for someone whos only ever seen FMA with knife and Stick, what exactly does FMA sparring consist of? Does it have empty hand? ITs probably a dumb question, but we dont have it anywhere in my area, so Internets basically the entirety of my exposure.
