There are two types of choke: Blood Choke: Cerebral blood flow (CBF) chokes involve restricting the flow of blood to the brain, thereby denying it of oxygen. Strangle: Windpipe (Air) chokes involve compressing the trachea which deny the entire body of air. This shouldn't be done in training to the point of unconsciousness as it can cause tissue damage ...

Studies Where We Choked People Unconscious In a Lab Being choked out might not be good. But we have very little evidence that shows that it's bad to any significant degree, and considerable evidence that being choked out doesn't seem to be of notable danger: There has been limited medical research regarding neck restraints. One of the first studies was ...

and I expected him either to break free or to tap out. When I looked down at him... There would have been a physical sign that your instructor had lost consciousness, like his muscles relaxing and possibly a slight change in posture. You need to be considerably more aware than you were. You cannot always rely on your training partner to know when to tap ...

Worth making the distinction between a blood choke and a air choke. ie, are you cutting off the air ( through the throat) or the blood (through the arteries). Throat choking is a lot more dangerous because of the damage you can do to the actual throat. Can cause swelling, etc and can cause people to die some time later. Blood chokes, less dangerous, ...

Most people acknowledge that, given that Brazilian Jiu-Jitsu is derived from Maeda's teachings in Kodokan Judo (then known as Kodokan Jiu-Jitsu in the appropriate romanization of the time), it is recognized as a derivative of Judo, but they have each long-since taken very different paths. Jujutsu (the modernly accepted romanization of 柔術) is a broad term ...

There are two types of chokes: a blood choke, in which blood flow to the brain is, at least temporarily, halted; and an air choke, in which compression to the trachea or chest stop airflow into the body, and thus oxygenation of the blood. Both are inherently dangerous. During an air choke, excessive pressure can lead to the collapsing of the trachea or ...

Genuine Brazilian Jiu-Jitsu all stems from one man: Mitsuyo Maeda of Kodokan Judo. Maeda had numerous students the world over, and upon settling in Brazil, was featured in a circus there, where he was seen by Carlos Gracie, the eldest son of Gastao Gracie, a business partner of the circus there. Carlos was accepted as a student, passed on his training to his ...

I want to be able to be prepared against any kind of opponent. You are looking for a unicorn there. No martial art whatsoever is able to do that. There is no ultimate fighting art. That said, most martial arts (McDojo excluded) can give you an edge in self defence. It will shift the odds in your favour which is a good thing. However, self defence is ...

There are a number of common issues in maintaining a mount. Examine your mount, and perhaps you'll find one of these to be a problem: No base with your knees – When you're riding low, you need to create a strong base, and your knees offer you that base. Keep your knees out while pulling your feet in to give both control and a base at the same time. Stop ...

A good way to get gi / kimono specific grip training is sling your gi / kimono top around a pull up bar or a tree branch and use that to do any number of exercises, such as Pull ups, grip the lapels and hoist yourself up Grab lapels and pull yourself up Grab lapels and bring your lower body up and wrap your legs around the gi in triangle position Just hang ...

The relationships between judo, Kosen judo, various traditional Japanese jujutsu ryu, groundwork (newaza), the nature of challenge matches during that period in Japan, and pinning a style on a given grappling expert during that period in Japan are all very complicated and deeply interconnected. In my view, if we are to develop an understanding of this ...

Depending on if the choke is on and how their arms are positioned here are a few options I'm aware of and try to work on (these are very brief descriptions, barely scratching the surface of back and RNC defense, to get you started on further research): Hooks in no upper body control - Protect your neck with the "V" "prayer" position , flare your legs out ...

1. Relax Just try to Relax. Sparring isn't a fight for life or death. It isn't even a competition. It should be a playful way to work on your grappling. Even if you go hard you should still be relaxed, a tense body just doesn't move that well. This takes some time, but you will get used to it. 2. Grapple The best way to build grappling conditioning is to ...

This is an age-old question about training in general. It's generalized as the "Breadth vs. Depth" dilemma. A "Depth First" training philosophy would prefer to train in a small number of things, but teach them deeply before moving onto other things. This way, you get really good at everything you learn, but you won't have a good understanding of the broader ...

First, you need to ask your instructors and senior students about anything you see them turning their noses up to. Do this reflexively. Always ask why. If they have no good answer for you, other than that they just don't do it, then that's your answer. Otherwise, this is the sort of question that will lead to a much better understanding of Brazilian ...

As a former LAPD police man who went through academy training in the early 70s, I can give testimony about the bar arm control hold and its effects, on other police cadets and myself as well. We were taught to know what to do when gaining consciousness, how to identify by hearing, where our main threat was (man with a gun) and how to proceed. Naturally in ...

I've personally seen the following, in various combinations: going slack tensing up and shaking sputtering blinking/twitching eyes glaze over eyes close snoring It's a lot easier to tell as a third party, since you can see things like the legs going limp while their upper body is locked in position by the choke. It helps to have a coach or whatever ...

Most Brazilian Jiujitsu schools do have children's ranks which automatically get turned into adult ranks when they turn 16. So a children's orange belt will become an adult's blue belt automatically at age 16. A children's green belt will automatically become an adult's purple belt at age 16. This is usually how it's done, but a teacher might decide to award ...

It seems a number of females share your problems. I read a number of female BJJ bloggers, and they have expressed similar feelings. My suggestion is to read what they have to say and maybe reach out to them: A tiny, shy woman who is mad keen on jiujitsu and gives a brutally honest account of her journey. A post a little while ago where she talks about ...

Gi and no-gi have a long rivalry in BJJ and grappling that has changed character dramatically over the course of the art's history. Most modern jiujitsu practitioners from the US train both and don't think much about it, but there are still a significant number of polemicists on both sides. BJJ came from judo, which trained exclusively in the gi, and so was ...

there are a few things you can do to help with this: break down your opponents posture, it's very hard, if they are sitting tall, even for someone with normal/long legs to keep the guard closed. use your legs to draw them in, and lock up their upper body, this keeps them closer, and makes it easier to keep your guard closed. develop a good open guard ...

I'm in construction and like to grapple in my spare time. I read somewhere on here someone recommended Horse Stall Mats.. thats a no-no.. falling on Vulcanized rubber is like landing on concrete, but you get a nice skid burn on top of that. I saw someone else say to make your own out of plywood, styrofoam, carpet underlay foam and drape your own vinyl... ...

My experiences in judo and BJJ The judo club I trained at regularly for several years was about 50/50 between newaza and tachiwaza (groundwork and throws). (Actually, it was more like 43/47/10 with the 10% being kata and standing joint locks.) My time at other judo schools has showed the ratio to be fairly different: 75/25 in favor of throwing, or even ...

In Living the Martial Way, Forrest Marshall makes the insight that you should run like you want to fight: if you want to fight at a slow, plodding, constant pace, then run long distances at a slow, plodding, constant pace. This advice is a gross simplification of exercise science but it is basically true in this context. Your coach is right. Long-distance ...

Concepts are great In general, I agree: concepts are the underlying part of all jiu-jitsu that works. Posture, base, leverage--these will be constants across all techniques that work. I think Kit goes off the rails by extrapolating from his experience to advice for the general populace, however. For instance: One of the things I noticed early early on ...

I assume you are working on the arm bar known in judo as juji gatame. The principle in this technique is the use of a class 2 lever to hyperextend the opponent's elbow joint. Resistance is in the middle, at the opponent's elbow joint. Force is applied by pulling down at the wrist and raising the hips. The fulcrum should be one of your legs; this makes any ...

The requirements for blue belt vary from school to school. What is required at Roy Harris' academy is not what is required at Renzo Gracie's, Marcelo Garcia's, and so on. The Straight Blast Gym had a good article about how to view the goals of each belt progression. Here's the section on going from white to blue: White to Blue: The journey of white ...

You're going to get a lot of push-back and they'll probably close this question, but you're not far off. Hard-sparring arts have proven themselves in ways that non-competitive arts have not. However, don't forget that other arts spar hard as well: san da/san shou is akin to kickboxing with fast throws and takedowns. However, like how all modern mixed artial ...

In Brazilian jiu-jitsu with a gi you wear the funny Asian pajamas. In no-gi Brazilian jiu-jitsu you wear shorts and usually a t-shirt or rash-guard top. You can grab onto the funny pajamas but you can't grab onto any clothes in no-gi. The gi absorbs sweat, adds friction, and provides a wide variety of grips to choke, throw, and control from. Often the ...

There is no "ultimate method" in a street fight. Ground grappling is really good if you end up in a one on one fight, on the ground, with no weapons involved. Fights tend to go to the ground because people have bad balance, it's relatively easy to trip or get knocked over something, and the tackle/bum rush doesn't require a lot of skill to use. ...
