This is not about BJJ, its not about wrestling, it’s not about judo. It’s about grappling or ground fighting. As an instructor once told me, “grappling at the highest levels is all the same”. What this means is that the fundamental concepts of grappling are the same no matter if your a judo black belt or a kushti wrestler. Of course the rules of your particular game may differ but the physical concepts of leverage, momentum, weight distribution etc don’t change.
In grappling there are two main facets to consider. One is positional dominance and control and the other is submissions.
Positional dominance is controlling your opponents body on the ground, an example of this is having someone in the full mount which is where you are sitting on top of your opponent. The person on top is in a dominant position because he can rain down strikes wit great effect on his opponent due to gravity while his opponent is pretty much helpless. Positional control comes into play regarding how effective you are in holding mount. You could get the mount position but then have huge problems staying on, constantly defending the chance of being bucked off. However, for someone with good positional control they can sit on top of their opponent and no matter how hard the other is struggling to buck them have total control with which to rain down effective strikes. Wrestlers are known for being very good with positional dominance and positional control.
Submissions are techniques applied on the ground (however they CAN be applied standing but are much harder to pull off, almost never see this in a pro fight) where a limb in manipulated beyond its normal range of motion causing pain and the potential for serious injury or when a choke is applied causing the opponent to lose consciousness. The most well known and utlized art form for this aspect of grappling in MMA is Brazillian Jiu Jitsu.
They are different animals but very closely related to each other with a few exceptions. The link between the two lies in the fact that generally speaking, a submission is much easier to obtain when you are in dominant position.
It’s all in the hips, is what my BJJ instructor always tells me. There is a lot of truth in that. To control an opponent, controlling their hips is very important. With the hips your opponent will try to get to guard, buck you off or scoot away to get to their knees. Controlling the hips is very important. This does not mean you should ignore the upper body, it just means that it requires more strength, attention, focus and technique to control a good opponents hips than it does his upper body.
A good drill to do for first time grapplers is to take turns with a partner trying to control each other in either side mount or mount. This will teach you to get used to being pinned underneath someone and remaining calm while looking for a way out. It will also teach the controlling partner how to remain on top of a resisting opponent without losing position. There are many techniques that are involved in this one aspect of ground fighting however this lays down the foundation of what is a long road of learning.
So they key point that one should learn from the article is that learn how to control position before submission. This is particularly true for MMA because from a dominant position you also have the added option of strikes making your top position all the more advantageous.
