comment How dangerous is it to choke someone unconscious or to be choked unconscious?
Quick Google brought up: A 26-year-old amateur MMA fighter named Dustin Jenson died last Thursday, after suffering a seizure following a triangle-choke loss to Hayden Hensrud at a Ring Wars event. Admittedly not precisely judo training, but you get my point. Young people can die, and if it happens 1 out of 100,000 -- if you're the one who killed a 26 old, you wish you had been more careful for the rest of your life.

About lack of evidence of ill effects, again, this means nothing at all. It is something that neither you (nor your judo association) can assert. I am a MD, and heck, I can't. It is very possible for someone to die in a car accident or cardiovascular event caused by unconsciousness or convulsions or hypotension, maybe days later. It will never be correlated to choking, and nobody will know. The only thing that is 100% certain is that unconsciousness and convulsions have a higher overall mortality (both immediate and long-term) than not having either of these.

@DaveLiepmann: I'm need not be convinced that choking is safe, because I'm not opposing to choking as such. I'm sounding a note of caution about choking in general (there is a human attached to that piece of meat on the floor), and I'm opposing to choking without reason, in particular to unconsciousness which is a big difference. As I've pointed out, unconsciousness is a life threatening condition, no matter how often you deny this, and no matter what kind of study you dig out that says this or that metric returns to normal after regaining consciousness.

This "ignorant" statement shows that she has an understanding of human physiology (not very surprising considering her profession) and at least a minimum of responsibility. The fact that something happens hundreds of times every day has absolutely no bearing. In Pamplona, thousands participate in bull running every year. During the last 80 years, only 15 people have died due to injuries. According to your reasoning, one could argue that running down a narrow street followed by two dozen angry and panicking bulls is perfectly safe, reasonable, and advisable.

"The LVNR system has specific after care guidelines. Officers must obtain field medical clearance for subjects who were placed in the LVNR whether they were rendered unconscious or not. There is a mandatory 2 hour observation period for anyone who has had the LVNR applied. [...] not to be applied to people with cardiac disorders, children" -- this very clearly suggests that they are not at all concerned about potential ill effects or lethalities :-)

Let me provide an analogy: You're sitting at a dirty table in a bamboo hut while the person on the other end of the table keeps shouting "đi đi mau" at you. You put a revolver into your mouth and pull the trigger... CLICK. You're alive and have no ill effects. Your brain shows a normal EEG. You repeat the experiment 4 more times, still no ill effects are observed. Conclusion: You can put a gun into your mouth for training purposes, there is nothing to be afraid of. -- How reasonable do you deem this conclusion?

such as "mild tonic and clonic seizure [...] No deleterious effects" you have to ask yourself "WTF?", and when someone says "...regained consciousness EEG returned to normal" you have to ask: "yeah, well, what else?". A normal brain will of course show a normal EEG, but that does not mean that it's not dangerous to choke that person to unconsciousness. Look into studies about cardiovascular effects of seizures or sudden unexpected death in epilepsy to get an idea of why seizures might be considered deleterious (tip: 5-fold increase in mortality).

My position is that unconsciousness is already a dangerous, possibly lethal condition when fully equipped medical professionals are attending. Even more so when they are not, in a dojo or in a backyard. Practicing martial arts, more than anything else, means learning responsibility, and avoiding unnecessary damage to one's self and others. It is markedly easy to injure, maim, or kill a healthy person, even without intent. As for the studies you posted, I did not check them for methodic validity because they are meaningless for the matter (and some are outright cynical). When you read things

@DaveLiepmann: The reason of shock kidney is an extreme hypotonia, whatever the reason (that's secondary). I can't tell about vasovagal syncopes being a "training goal", but in my opinion this would be a rather stupid goal, as it is dangerous. You could as well have your partner stab you in the eyes or repeatedly kick you in the testicles (without protection ofc) to "harden" them. Some things are just dangerous, and one shouldn't do them, simply because they're dangerous. Doing dangerous things for "training" leads to Bad Things Happening™. Maybe not the first time, but eventually.

@DaveLiepmann: Carotis sinus massage is a known therapy for supraventricular tachycardia, and a known cause of vagovasal syncope. I recall seeing the latter once with school kids choking each other. Shock kidney is something I've seen 4 or 5 times in my life in people who were "fine" after trauma with shock. Death due to aneurism in young people is admittely something that I do NOT remember seeing ever, but it is something that can conceivably happen given a) enough "stimulation" and b) being unlucky to have an aneurism.

comment What martial arts cultural remedies are there to avoid and relieve soreness?
Tiger balm does work wonders (though it's as expensive as gold). Capsaicin, e.g. rubbing a habanero on the skin, works wonders too, though you had better be careful with coming anywhere close to your face afterwards, even after washing hands.
