I remember watching that and I always feel bad for the man. Good thing he got himself under control... One can only imagine how much this stuff messes with you. And thanks Seth for not making fun of him but actually aknowledge how dangerous he is and how bad of an idea that was. Seriously thought you would make fun of him tearing up. Thank you

[@UnpleasantAlex]

It doesn't mess with you at all. I've had epinephrine multiple times. It doesn't affect you mentally at all (he obviously has issues). You're just able to be at peak performance for way longer than you should be able to, and you don't have to put effort in to hit it. I voluntarily withdrew from a swim meet on a day I'd had to take it prior because I knew I'd have an unfair advantage. I timed myself during warm ups to see if it'd left my system yet...was hitting my 50m time 3 seconds faster than my top time, and it felt easy.

[@maddinkn]

[@MidwestArtMan]

I learned from research into the death penalty for college that ft/lbs equals pounds times feet fallen. Basically, it takes 1,000 ft/lbs to reliably break someone's neck, but not decapitate them. So, if they had a 200 lb guy, they'd drop him 5 ft.

[@al-imranadore1182]

[@kungfukitten6735]

Gotta say putting your ads where they’re ad breaks are is kinda genius.

[@Elriuhilu]

One pound of force (or pound-force) is the gravitational force exerted on a mass of one pound. It is calculated by multiplying one pound by the acceleration due to gravity on Earth expressed in feet per second squared. I have no idea what the acceleration due to gravity is in ft/s^2 because practically no-one uses those units, but there is a similar unit that's also not used called a kilopond (or kilogram-force), which is essentially the same as pound-force except using kilograms and m/s^2. The normal, SI units of force are kilogram metres per second squared (kg•m/s^2), more commonly referred to as Newtons.

[@matthewschafer6359]

Making sense of units of force can get confusing, so maybe this will add some context; the average untrained person swinging away can, on average, hit with around 200 pounds of force (which is more than capable of causing a knockout if delivered into the right area). So 200 pounds is like a haymaker from your typical tough guy. Someone trained to throw a punch is going to hit with around 300-500 pounds of force on average, like someone with martial arts or boxing training (granted boxers typically hit a lot harder). A professional boxer who is both skilled, muscular, and has developed pushing muscles can get up around 700-900 pounds of force. Heavyweight boxers can get over 1,000 pounds of force in their punch, with guys like Iron Mike Tyson capable of over 1,500 pounds of force. So to help the numbers make sense, a kick that hits with 1,000 pounds of force is like a hard punch in the face by a good heavyweight boxer. Force is calculated by taking mass and multiplying it by acceleration, so in other words to hit hard you have to take something that weighs a lot (mass) and get it going really fast (acceleration) and that will generate energy, and then you have to ram that thing into an object to release that force. We could say force is essentially the energy released during a collision, like a fist with a face. To hit harder (get more force) we need to either increase the mass (make that object weigh more) or the acceleration (move it faster). Thats why keeping your elbow in and twisting your hip let you punch harder; keeping your elbow in connects your arm to your body so instead of hitting with just the weight (mass) of your arm you're hitting with the weight of your torso as well. Twisting the hip increases the speed of the punch (acceleration) by adding the speed of your rotating hips to the speed of your fist, much like throwing a ball while riding in a car. What is perhaps more important than all of this is the force transfer. It doesn't matter if you can generate 1,000 pounds of force if you can only transfer 300 pounds of it into your target. As soon as your punch makes contact with the target all the force you generated by swinging your fist gets released and starts leaking out everywhere. Some of that force becomes heat, some becomes sound, some travels back towards you, some travels out into the air, and some goes into the target which is where you want it. The trick is to transfer as much of that force you generated as you can into the target instead of it going into other things. If you can do a smaller punch (which is faster and harder to see coming) that only generates 150 pounds of force but you transfer almost all of that into your target that is ideal since its minimum effort but maximum effect. That's a secret of a lot of the Chinese arts, they focus on transferring as much force as possible instead of generating a lot of force and then possibly wasting it, and that is why a lot of their strikes as small, tight, explosive, and not easy to see. The transfer of force is determined by tension, alignment, time in contact, and vector (direction). If you go back to the video of Fight Science and watch the boxer hit the dummy where does his fist go after making contact? If their fist hits the dummy's chin and then as their punch follows through it slides off to the side they're losing force that could have be transfered. Ideally you want to follow through so your fist lands solidly and keeps pushing forwards without leaving the target, you want the punch to travel in only one direct and keep contact with the target for as long as possible. To transfer as much force as possible you want the target (the other person's body) to move away from your fist instead of it being the other way around.

The guy who gets hit in the throat in the video is Shihan Joey Harvey, also a very skilled and knowledgeable man. Back then, unfortuantly, they were affilated with Juko Kai and "Dr" Rod Sachornoski. Now they have formed there own council that encompesess Japanese Jujutsu dojos across the south U.S. Shihan Harvey here in my home town actually also teaches Erik Paulsons CSW and STX Kickboxing

This guy had balls

[@jasonerickson1753]

This show was all over the place. The groin kick generated 1100 pounds of force, while the muay thai kick was estimated at 780+ pounds to break the bat. The Assassin on natural adrenaline punched with 1000 pounds of force. Taking a groin kick the way it was demonstrated in this video is something I've done. There's a trick to it that doesn't require years of training and conditioning. I've had a friend shin kick me in the groin so hard that my heels came slightly off the ground, and he did that multiple times. It has no real combat value, but it's an impressive parlor trick. Done correctly, it doesn't matter if the kicker is in front of you or behind you, and you don't have to see the kick coming. I would be far more worried about a thigh kick. Those are much harder to take unless you put in the years, and even then you can be dropped with a good one. I would like to have seen the Assassin groin kick the dude while on adrenaline.

[@KatonRyu]

As someone who does krav maga and gets kicked like that a lot, I'd love to know the trick. Even wearing a cup it really does suck.

[@jasonerickson1753]

@KatonRyu I may have video of an old demo that I could post. I'll take a look. I don't think it's practical for realistic sparring, let alone combat, but it's a neat trick. My friend and I figured it out in about 45 minutes when we were way too bored one day. In person, I can teach it in about 10 minutes, but it usually takes longer than that for a person to believe it's possible. 😂

[@Bennettje04]

This is “Combat Ki”, Developed by Soke Rod Sacharnoski. They have done demonstrations for years on different shows all over the world. Kirby is a great person as well as many of his associates who train with him. The Ki is only part of the system and there are no cups or tricks. The old school guys were pretty tough back in the day. I have read the comments about tricks but as with any reaction to a strike, the more you train the faster the reaction, clinch, tighten up, breath, etc. I don’t know of many men who have balls high enough that they can tilt their pelvis up enough to prevent being struck to some extent by a kick, shin or foot. I have trained in this system and yes, took kicks to the groin, strikes to the neck, ribs, solar plexus. I think you should try for yourself. I can put you in touch with some active practitioners(?)

[@MMarbleroller]

The groin kick is a carnival trick, a stunt man tecnique. The "flinch" at 1:10 is not accidental. It is an intentional rotation of the pelvis that moves the lower muscles of the buttocks forward, flexed. This puts those muscles between the shin of the kicker and the pelvic bone. It also rotates the testicles further upward and away from the kick. The shin against the floor of the pelvis, against the flexed muscles prevents direct impact against the testicles. It is very important to the technique that he kicked with the shin bone and not with the foot. Look on the video, the foot comes up behind. This is how stuntmen do groin kicks. It allows a full force kick between the legs without actually striking the testicles. The rotation "flinch" is critical to the method. If the performer does not do the rotation, then the pelvic bone is unprotected, and the testicles are not rotated away. That is not to say what was in the video was not impressive. Even a stunt man technique, with that much force, is going to transfer a lot of kinetic energy up through the body. But it is not, in any way, the same as taking what we normally think of as a groin kick. There are several episodes of Fight Science where the show portrayed essentially carnival stunts - magic tricks - instead of real demonstrations of what they claimed they were showing. Spear bending in the throat and crap like that. While a lot of the show was straight up and interesting, there were enough of those kinds of things that the makers ought to be embarrassed.

[@blackmetalassasin1]

As for the bat break, if you're ever curious, look up some traditional uechi-ryu karate demonstrations for body conditioning. I'm sure the muy thai guy is pretty tough, but I've seen dudes in their 70's and 80's do a hell of a lot more.

[@MojoKingWojo]

I did Jujutsu with people who trained with that Sensei and I went to one of his seminars, he even came to my high school and had the Punter and Kicker of the Football team kick him in the nuts. They also do up to 4 sided strikes to the neck at the same time, and various other techniques to the abdomen. The difference of Jujitsu and Jujutsu is, Jujutsu has weapons in the curricular as well as open hand btw.

Ft lbs of force is a measurement of the force needed to move one lb of mass one foot absent other resistance or interference, such as bending or crushing.1000 ft lbs is the force needed to move a one pound weigh 1000 ft or the force needed to move 1000 lbs one foot.

[@theaikidoka]

Two points; 1) There must have been a LOT of waivers signed on this show. Jacking up the heart-rate like that is not good for your long-term health. 2) I believe (though I can't do it personally) that with the right training a man can voluntarily withdraw the testicles back into the body cavity, to the position they are in pre-puberty. If so, then that kick would have been onto an area of relatively thin flesh over bone, simlar to being kicked on the forearm. Definitely painful, but nowhere near as debilitating as being kicked in the nuts. If he isn't doing something like that, a kick that powerful would have just damaged his balls, so it doesn't really matter if he can ignore the pain, he's getting hurt anyway - like it doesn't matter if you 'fight through' someone sticking a thumb into your eyeball, your sight is getting damaged. There's a 'trick' to this, but I'm not familiar enough with anatomy to know what it is.

[@Bearman-my8dj]

How do you explain the kicker saying that he felt the dude's balls on his shin? There have also been other combat Ki demonstrations where they let people hit them in the balls with their hands to prove they are hitting them in the balls. Unless they are hiding their testicles in the cavity and then using a silicone fake to trick the hitter into believing they are connecting their their testicles. That is a pretty elaborate setup though. The explanation the show gives is that due to Wolff's law, supposedly, their testicles have hardened after repeated conditioning training. But, my understanding is that Wolff's law only applies to bone, and the testicles aren't a bone. The thing is though, if its not that their testicles have hardened, its hard to imagine what else it could be because they can also do full power throat chops and take strikes to other vitals without feeling it. The prior episode of the clip he took a full power throat chop from the same guy.

[@theaikidoka]

@@Bearman-my8dj I explain it by saying I didn't hear him say that, possibly because Seth was laughing. I don't think Wolff's Law applies either, MAYBE something like what Kickboxers do to destroy the nerves in their shins? If so, it seems needlessly elaborate when you could get a similar effect by, you know, dodging or putting a different body part in the way. A hand, hip or thigh for example.

[@tombayley7110]

Seth! I am shocked that you have not learned how to be kicked in the gonads yet. What you describe as a nervous reaction to the kicker checking his distance is actually the guy receiving the kick rolling is tailbone under. this has the effect of rotating the glutes down and the testicles up. this puts the glutes below the testicles. now any kick delivered with a swinging upward punt action will hit the glutes first. The gonads may not actually be hit at all, particularly if you ride the kick up by lifting onto your toes.
