I love using the rear naked choke, I've used it a decent amount of times while working security at bars and events. It's the best tool that I received while training in Brazilian jiu jitsu for the short time that I trained, and I hold it dear to my heart. I appreciate this video, because it uses the same concept, but it's applied by the use of strikes. I like the science of fighting, because no matter how tough an opponents head might be, it's going to shut down without being supplied with blood and oxygen. Fight sciences approach the human anatomy the same way that a mechanic disassembles an engine step by step. It doesn't even seem violent sometimes.

[@BuddyLee23]

Nickie Lee if you can find a link for the video you should post it here. It would be good to see some real life examples of this technique in action.

[@GMan8523]

Great video as usual, but I had one technical correction to add. The technique does not work by restricting the blood flow to the brain. There are additional large arteries that provide sufficient blood flow to the brain to maintain consciousness. The Carotid Restraint and strike works because it activates the Carotid Sinus, which monitors blood pressure in the artery. The compression from a squeeze or strike is read by the Sinus as a dangerous increase in blood pressure and in order to protect the body it dilates the blood vessel and shuts down non essential functions including consciousness. It basicilly makes you faint. As a former Law Enforcement Defensive Tactics trainer the Carotid Restraint was always under attack as a law enforcement tool by anti-police organizations as a choking technique that restricted blood flow to the brain. The inaccurate description of how these very effective techniques work is why they are currently banned by most police departments that don't have the will or desire to fight back and protect law enforcements use of these tools.

[@lifeinlimbo2186]

Yep...same method used in 007 James Bond movies. Been a practitioner my whole life and i love your instructions. You do not mess around and your knowledge is vast. Save a micro second when your hand is on their arm after a block and instead of flipping hand over for strike,immediately strike with hand in palm down position using your tucked thumb side of hand. In a real fight,every second counts,of course,so even if i miss when i swing, as i draw back my arm,i try to strike on the way back. Every strike in one direction,has the possibility of a second strike,or diversion strike on the way back. Kind of like a bullet that when it misses you,it immediately comes back from behind. Does not always work,but NOTHING always works.

Love your channel Sifu. More than just restricting the blood flow you’ve actually got special receptors in the carotid artery (baroreceptors) which when stimulated slow your heart rate and drop your blood pressure.

Hi Mark. I really enjoy your reality-based videos and often share them with students. Keep it up. I have experienced the effect of the carotid strike first hand and I dropped. I would add that it is not just the restriction of blood flow but also the effect the strike has on the vagus nerve. Question though. I watched your video "bodybuilders vs skinny" and it got me thinking about how effective a carotid strike would be against a someone with exceptionally well developed sternocleidomastoid muscles?

@@tombrady3086 lol

[@333dsteele1]

You are actually hitting the barowreceptors on the internal carotid near the bifurcation of the carotid that causes the effect. The barowreceptors control blood pressure and by suddenly stimulating them with a strike the vagus gets activated and slows the heart dramatically, blood pressure plummets and person falls unconscious. Risk is prolonged asystole and death. Usually the heart is slow for a few minutes then speeds up and person regains consciousness. This effect could also happen in strangulation, as well as the explained mechanical effect of partially blocking the blood supply between head and rest of body. Mechanical obstruction doesn't happen with strike as its too fast. Internal carotid is at the side but towards the middle, just under chin at side of trachea. Another reason to keep your chin down. Also that was his external jugular vein on the side of his neck you showed, not the carotid which is mostly under the sternocleidomastoid muscle.

[@randysmith2490]

What’s highlighted at 1:03 is the external jugular vein. Compressing it with a rear naked choke allows for a pressure buildup in the brain which will lead to unconsciousness after several seconds. Carotids are closer to the center of the neck, under the jaw line. There’s a bulb at the carotid bifurcation (into external and internal carotid arteries) which can be massaged to drop someone’s heart rate; hit that, and a neurological signal is sent to the heart to slow the heart rate, which if done while the target person is engaged in aerobic activity will lead someone to pass out. Hitting the jugular vein with a strike will neither change intracranial pressure or heart rate. I’m a martial artist (aikidoka) and an internal medicine physician.

[@danielskipp1]

With all due respect, Sifu, I would like to nitpick. ;-) Your description of the mechanism of the effects of a carotid sinus strike is not exactly correct, in that the mechanism is slightly different from a blood strangle "choke", as the blood supply IS interrupted but it is mainly NOT via the same restriction preventing blood flow in the carotids. The KO effect in fact comes from 1 or both of 2, TWO, mechanisms: sudden compression near the baroreceptors [pressure detectors] in the carotids, making them send a signal to the brain that there is dangerously high blood pressure which then triggers the fainting response by the brain to get blood pressure down fast AND/OR disruption of the vagus nerve which regulates the heartbeat rate, causing a stutter in the heartbeat. Both cause a drop in blood supply and a nervous collapse. Naturally a carotid strike can restrict the blood flow directly but the effect is so quick as to be minor, unless the artery does not open up again.* Perhaps insignificant a point as the effects are usually the same, but it does mean one can get a stun from a simple push into the carotid sinus, and a strike is instant and does not require the same continued pressure as a strangle [or as the BJJ people now call them, a "choke"]. The stun effect can take a second or more to really kick in, unlike a concussion KO, which is a disadvantage but they are usually still incapacitated to a degree before then. as you know. You are going to hate me! I have not finished! You note that doubling up, alternating opposing side carotid strikes, is very effective, which is true and good teaching, but, again, I don't think the real reason is entirely as you state, like compressing both sides in a choke. My dim mak teacher said that it is a nervous and/or chi effect, neural shock from opposing sides of the body, that works synergistically, not per se to do with having both carotids' blood flow interrupted, though of course it would seem on a double carotid strike that would help with a stun so I guess it is a bit of both. One can get the same synergy from other parts of the body [e.g.arm and opposing side neck, leg and opposing side arm etc.]. *This can happen after a strangle/choke too which obviously could be fatal... RNC's have killed people after they were released. Of course, while the carotid attack avoids the dangers, you rightly note, of hitting the jaw it has dangers of its own, not least the risk of brain damage when they fall KOd onto concrete, not to mention the risk of a stroke or even major haemorrage or a heart attack from disruption to the vagus nerve. It is not the safest of techniques!

[@fightscience]

Thank you, of course you are welcome to nit pick. I'm aware of the effect of the Vagus nerve, I thought a more simplistic explaintion was appropriate for this video and time allowed. While there is a risk of a major haemorrage or heart attack, these risks are likely increased in relation to the age, physical fitness, and health of the person being struck. There is an equal risk of stroke from being choked. In this view, applying such a strike to a middle age obese gentlemen with health problems is likely to carry a higher risk than a younger fitter attacker. In which case, the comparrison of safety is relative and context specific. Having said that your points will duely be noted by all reading out comment section, so thank you for adding. Thank you :-)

[@NotQuiteLucid]

This doesn't explain proper technique for the Shuto knife hand, just one place to strike with it. Anyone who uses this without conditioning and strike training is more likely to fail. Proper form of the Shuto should make all the muscles in the forearm flex making the hand and forearm into a single edge. The small finger of the hand should be pushing outward slightly with the rest of the fingers pushing onto the small finger. The index finger should be slightly bent and the thumb pushing against the index knuckle. The knife hand should be conditioned by repeatedly striking a hard flat surface 5 times daily to start for the rest of your life. This is the iconic karate chop.

Unless you're on some sort of military operation, it sounds kind of cowardly to me. Sneaking up behind somebody to coldcock a person that's (I assume) is unaware of your presence and intent? I dunno man. If you're gonna go, go straight up. Square off, he knows, you know... Besides, why would you even want to do that at all? Actual combat should be the last resort. If it isn't, you're risking injury to yourself, possibly MORE injury to your opponent that you intended (such as him dropping and slamming his head and dying or serious, life altering brain injury) resulting in a criminal trial for yourself. I happens. I know this personally. And for what? To be a "tough guy". Dropping a guy that didn't even know what was coming up behind him doesn't make you a tough guy. It makes you "an aggressive coward". Square off, make yourself known. Make it known you're deadly serious. Give the other guy a chance to walk away. Of course, if the opponent is the aggressor, than all rules no longer apply. If you're fighting for your life and/or the life of a loved one or someone that's being attacked simply for being weaker, than yeah, by all means, do what you gotta do. Bottom line: Use your head. With great power comes great responsibility. Use that power when in the wrong and more often than not, you WILL be held responsible.

There are a number of factors to consider. Firstly the age and health of the person being struck. If they are young and fit, then they are likely to have a higher tolerance to a knockout strike to the neck. Reverse is likely for someone unfit or old. A medic on our team does advise that repeated striking of the sternum clavicle mastoid muscle may lead to swelling that could be fatal if repeatedly struck. Of course this is extremely excessive and difficult to defend as reasonable force in a court of law. Thank you for watching.

Stop thinking about fight but think about self defence and then it works🙌🙌🙌

I had decided to give the link for your channel to my son after watching several of your videos. There is so much rubbish online but I see a lot of what I found effect included in what you advise. When I use to train, I have always found it interesting how many people drop their guard or don't think to guard their neck and collarbone, the area I used to stop an attack on me when I was 20 years old by some bloke who mistook me for someone else and decided to gay bash me. These techniques are effective. I think I broke his collarbone though when I used the side of my open hand.

[@garymasterson1174]

Thank you. Your channel is excellent but on this occasion I think I may have something to offer. Completely agree that neck strikes (from any angle) are highly effective and can certainly result in a knock out, However, I have two comments: 1. The knock out does not result from the strike to the carotid artery causing a reduced flow of of arterial oxygenated blood to the brain because of its momentary effect. Pressure resulting from a choke (particularly affecting both carotid arteries simultaneously will certainly cause a prolonged reduction in blood food to the brain) will certainly result in unconsciousness but a momentary reduction in carotid blood flow resulting from a strike (particularly to one of the carotid arteries will not. I have pondered over this for a long time time and i am of the opinion that the knockout resulting from a neck strike results from the energy of the concussion to the cervical spinal cord being transmitted upwards to the brain stem. I am saying that the technique is high;y effective but that the underlying patho-physiology of the resulting knock out has a different has a different mechanism. 2. Neck strikes are profoundly lethal and can result in death really because of the possibility of medium term term damage to the carotid artery and other vital structures in the neck. If you are ready to use a well executed neck strike, then be prepared for the possible consequences which may include a man slaughter conviction. I am a senior doctor dealing with trauma and a low level martial artists which I hope gives me the credibility to make this comment. I hope this is useful and not perceived as critical. ATVB.

I like this a lot, makes perfect sense! Does that make it more similar to when you see a fighter drop after getting hit behind the ear?

I love the science of this guys approach. But is there any video footgae of him really fighting and using it?

[@Mountainofcharm]

Great, so why dont boxers punch the corotid or MMA fighters chop at the corotid if it leads to such efficient and fast KO's? You're allowed to as per sport combat rules. I'm calling BS

[@KM2558-o1y]

I like the level change. Obviously the strike to the carotid artery and/or throat will be effective. However, I think body shots are often underrated and have the benefit of being fist friendly.

[@chriszablocki2460]

Dear KZbin, Based on the recommended videos in my media feed, it seems that you're suggesting that I should either train for sanctioned fights or prepare for a nonsanctioned street fight. If so, I'd like to take a moment to explain why that is, in fact, not a good idea. In the case of training for a sanctioned fight, I have consider a) my age, b) the reward for the effort, and c) the motivation for doing it. In the case of preparing for a street fight, I have to consider the legal ramifications for doing so. I'll give an example. In the last altercation I was in, I was charged with 2 unnecessary charges. And I didn't even throw a punch. Is it fair for me to question the legal issues I'd be up against if I WIN a fight? Can you understand my reasoning? Self defense is great for everybody to learn. And can be a zesty form of sanctioned competition. But let me clear something up. This doesn't belong in my recommended video feed. Sincerely, Chris

This brings back memories of a fight I had as a schoolboy. I had been bullied quite alot and had been beaten up about 10 times. Cuts, bruises and nose busts etc. Got scarring on eyes now. Anyway I bought several martial arts books and learnt this but didn't realise or comprehend how dangerous it was.
