Mixed martial arts?

in mma, when they talk about the guard, half guard, butterfly guard, where are these techniques learned, are they a particular form of martial arts or just taught when learning mixed martial arts?

Mixed martial arts?
there grappling terms. they have been around for a long time. I'm not sure how they originated but they were used back in they old school days of pancrace. and no there not for just one martial art now these words are just generally accepted on all forms of grappling i.e. bjj, sambo, jujitsu, and even judo
Reply:do whats right dude
Reply:each art forum has a different type of guard when it comes to defending yourself on the ground or standing and then again they can be learned on your own or just done naturally from the cituation you get placed in but most of the time it is taught to you so that when you get in the position your know what to do and what not to do...
Reply:The various guard positions are references to postures used in ground/wrestling scenarios. They are not martial arts, just terms for body positions.
Reply:They're traditional wrestling and grappling terms for grounded positions
Reply:They are learned while training for mixed martial arts, you would learn them while practising and training for Brazilian Ju Jitsu or Submission Wrestling, or Wrestling of any kind. Its part of the defense needed durring the ground game. It is also a main part when learning straight BJJ, or Wrestling.
Reply:those are more specifically jiu jitsu techniques
Reply:They are Jiu-Jitsu techniques. Guard is when you are on your back the other guy is on top and you have your legs crossed on his back to control his hip movement. Half guard is when you have yuour legs croseed over just his one leg to prevent him from going into side mount or full mount. and butterfly guard is when you are on your back and the other guy is kneeling or standing and you have your feet on his hips usually while holding his head or back to control him.
Reply:The ground game and all those positions you just metioned are incorporated from Brazilian Jiu-jitsu. BJJ is one of the most(if not THE most) essential arts when learning MMA.
