[@mikebennett938]

@@SenseiSeth Fight science came up with a very similar list years ago. Tae kwon do was at the top of that list as well with Bren Foster so I don't think you are all that far off the mark. I think what is a really interesting question isn't so much how 'hard' can a person hit, but rather how much force do you need to stop an average opponent (of course relative to where you hit them). What we need when teaching is to show our students what it takes to shut the opponent down. With a device like this we can guide the student to improve their performance and allow them to set a real world expectation of what they can personally achieve. Once they can hit the 'magic number', which we know will stop most opponents then we can focus the student on how 'fast' they can strike and how 'precisely' they can strike the target, preferably moving. Maybe you could do a video on what how much force is required to knock a dude out with a head shot, bust some ribs or a femur? This would be especially interesting with different body sizes/weights to compare if you really need that much more force to stop a larger person compared to a smaller person. Then you are demonstrating end to end what all these numbers mean in practice. Remember though , BOARDS DON'T HIT BACK, hahahaha!

it's not like the relationship between weight and power output is linear anyway, so it doesn't necessarily yield an accurate result

[@herrmayhem1915]

I'm not sure if this was exactly the right approach because the body of the larger person also contains more 'stuff' (brain, guts, blood) that would not directly contribute to power/strength. I think this approach might favour the smaller people.

[@immanuelampomahmensah7909]

power is a function of force which is a function of mass and acceleration. Not entirely sure if dividing by weight is the BEST way to do this but it DOES make the acceleration component more influential

[@theaikidoka]

@@herrmayhem1915 This is true, and every possible measurement system has some flaws or preconceptions, but BROADLY speaking, professional fighters are higher in muscle mass and lower in fat mass, so as their total mass goes up, there's more muscle to use. That's why fighters are divided into weight classes as smaller guys simply don't have as much muscle - however, it's also why boxers are now compared pound-for-pound, so that a super flyweight can be meaningfully compared to a super heavyweight.

[@pihermoso11]

@@herrmayhem1915 it's physics, P=mv , momentum is equal to mass times velocity.. momentum is key in calculating for elastic and inelastic collisions, a heavier mass will have an advantage of having more momentum than a lighter object, a lighter object can compensate by increasing its velocity to achieve the same momentum of a heavier object, a thrown baseball has roughly around the same momentum as a bullet shot from a gun, that's what my physics teacher said..

I used to train capoeira with a guy that was a high-level TKD practitioner before starting capoeira. We would cross-train sometimes. His back spinning sidekick was the first time in my life that a kick, delivered in a training scenario, while holding a padded shield, lifted me off of my feet, and knocked the wind out of me. The kick knocked the wind out of me. Hitting the wall behind me was just adding insult to literal injury. There is something those TKD guys do in that freaking kick that is just plain deadly!

[@ssh7957]

Back kicks as opposed to side kicks activate your glutes more which is the strongest muscle in your body overall. Plus it adds a spin so there's some extra momentum.

[@notsospecial9012]

For that back spinning side kick, it’s so strong because it has that circular wind up to generate force like the roundhouse, but delivers that force through the bottom of the foot, mostly through the heel, as opposed to the top of the foot or the shin. This means more force delivered over a smaller area.

[@rayvincyful1]

It really hurts more to be hit by something with smaller surface area, but I don't think the cube measures pressure. It measures force so surface area doesn't matter. The elbow attack would have scored higher if so. The back kick is just strong

[@whiskeybuddha1995]

I found that the back kick is even more powerful (and easy to aim) when it’s thrown with your toes pointed downward instead of to the side. Not that the other technique is bad (as we obviously saw), just mentioning something I learned training over the years

[@-e6195]

[@kevingray4980]

In the roundhouse kick you have around 150° rotation to generate energy with a lot of centripetal force (energy spent redirecting, not increasing) In the spinning back kick you have around 210° degrees of rotation plus a more linear trajectory. Of course it hits harder.

TKD has been a part of my life i was literally born. my dad was a part of the founding team of the Korean Marines and then ended up coaching for the US Olympic team in the 80/90s. it’s crazy to see where the sparring (physical) side of TKD has gone. with the introduction of electronic gear. it’s gone from a thrilling and exciting competition into a strategic/fencing style sport. nonetheless, still love the sport but miss the way it was in the 2000’s.

Respect to all the Martial Arts. As a Muay Thai Trainer, I do believe it comes down to the weight as well as technique. The more these students come back to practice, the more they realize what they were doing right and wrong, and eventually develop not just the right technique to hit hard, but also the self confidence that they are capable of doing so. Great video.

[@brodacious1313]

When I watch Muay Thai videos I see the absolute monsters being really lightweight (e.g. Rodtang and Tawanchai) -- but perhaps that's just vibes generated from the commentators. When you say "weight as well as technique", what would you say is a weight range that better compliments Muay Thai?

[@KatimaGaming]

@@brodacious1313 thats a great question. In Muay thai and many other striking sportz, weight equals to muscle mass. The heavier you are as a fit fighter it is assumed the heavier you can hit and take a hit. But also cuz you are heavier, you also fatigue faster. More so in Muay Thai. Hence why smaller fighters are the norm, as they are fun to watch and can go the distance. The max heavy weight in traditional Muay Thai is 70 kilos. 66kg is also pretty heavy. Average fighters are around the 60kg range. Fighters try to stay as light as possible so that they can be matched up with smaller fighters as well. If you hit that 66kg, most likely you will be matched with a tall heavy foreigner that can clinch you and throw you around easy. Hope this was helpful!

And in a local muay thai non tournament event, you can get away with being heavier. At this point the question is can the promoters find anyone who would wanna fight you. Most likely not a Thai.

The TKD guy was able to generate ALOT of oomph with his push style kick because he didn't let his body get pushed back as much. He allowed alot of the force to transfer to the target instead of pushing himself off which is what ALOT of people do. Good on him for keeping a sturdy stance on one foot to tranfer all the power. You can even see that on his sub 50k kicks his body was going further back after the kick which means his weight rebounded instead of tranfering. That guy has solid kicks when he is focused.

There is a famous "Quick Shot"... that can pull out a holstered gun, shoot two cans at a distance, nailing both, in less than 1 second worth of time... and he can do this every single time, without failure. Peak performance, isnt a non-achievable thing. In fact, anyone Can and many people DO, achieve peak performance, in many areas of activity. Both as a sport, and in other areas, such as special tasks at their Jobs. When I went to master Short Range power... I already went in with a few years worth of mastery of the Wing Chun vertical fist punch. I probably used to throw a good 1000 punches every single day... in addition to my other training. As well as wallbag work. Special Pushups. Speed drills. And more more. To achieve my goal... I hung a canvas bag on a chain, and filled it without about 15lbs worth of steel bbs. At its widest point, it was about 7 inches in diameter. If you hit it properly, it felt like hitting a solid Iron Girder. Every single night, I would start out with my fist.. 12 inches away from it.. and then strike it. Reset, strike, repeat... for an entire Hour... (no rests). Id say that it initially took me about 50 tries, before Id hit it in the correct way... to attain "Fajing" (explosive power). After maybe three weeks time... I could get Fajing on every single hit.. so I moved from 12" to 8"... and started again. This time, I probably got the correct hit, once in every 30 tries. It wasnt as bad as beginning... but it still was a far cry from what I just accomplished at 12 inches. Eventually Id fully master 8 inches, and moved on to 6 inches. And probably by the end of 3 months worth of DAILY 1hr sessions... I had graduated to a SINGLE INCH of runway, and could Nail it every single time, flawlessly. At that point, I started to use it in sparring. The MMA gloves do in fact reduce fajing potentials.. because they are designed to absorb the most Initial impact potentials. That said... I had so much power, that it didnt even matter. I was able to KO any fighter, with less than 6 inches of runway, from my mostly extended lead guard hand. I could do this every single time I chose to... and I never needed to use any more than about 15% of what I was capable of delivering. In fact, anything more than that, would have been too dangerous. I proved this on 4 different disrespectful fighters. Three of which were blackbelt level Jujitsu fighters, at their open-house sparring event. Each of those 3, were dropped from the exact same punch, same distance, off the very first Exchange. The other fighter, was a different arts artists, at a different private sparring event. He studied a Korean art of Kook Sul Wan, as well as Capoeira. Years later, I used fajing strikes, in the form of my forearm based Interception. I used a 10% level deflection... and it nearly shattered an MMA fighters wristbone. In about an hours time, it had swollen nearly double in size, and he was in great pains, for many days to follow. You see... The real reason why so many of todays artists are total Trash... is because they never invest enough time and intense efforts, into full Mastery of what they have learned. If you throw a poor, weak, punch, or a sloppy, weak kick... and it failed to Drop the attacker in Ancient China.. that dude might end up Ending you, a few seconds later. There is no room for errors, when its Real combat... when your life is ACTUALLY in mortal danger. If a few thugs from the hood manage to drop you... they just might not stop kicking your head, until your brains are leaking out of your skull. Dont believe me?

Wouldn't make much sense to try to resist an incoming push kick as you would naturally hurt yourself more than necessary.

Capoeira is a martial art that is based off of movement and is dance-like because it was developed by slaves and they wanted to hide that martial art. Many times, they would have to fight off many colonialists alone, while escaping for example, so they needed to keep a certain level of distance to maintain the momentum that makes the kicks hit so fucking hard, and the side kick and front kick shown where examples of that intention

1) The measurement could be improved with the Kube fixed to an immovable object. The "uke" (holder) can subconsciously soften or strengthen the strikes. 2) Velocity-based strikes (TKD) need to be measured differently from mass-based strikes (MT). Even though kinetic energy for both is 1/2(mv^2), the velocity decay is longer for mass-based strikes. The PowerKube is better than any I've seen, but still can be better. I think the Human Force is a good idea in the right direction, but can be improved. 3) Contact area affects readings that are derived from measuring compression. If TKD man roundhoused with the ball of his feet vs instep using the same snap kick, the readings would be very different because the ball of foot strike will have significantly higher penetrative effect.

I don't know how the power cube calculates its numbers but my guess is that Impulse is the biggest factor. Impulse is force over time so the same force over a smaller time will produce a larger impulse, i.e. a round house kick is in contact with the pad a shorter duration than a front kick or side kick.

[@fourscorpio]

Loved this one, Sensei Seth! Back in the day (late 80s) there was a product out there called the Impax shield. It did the same things that this power cube does, except it had a LCD box that would measure power and speed (with a different scale). This was before you had laptop computers that could run advanced software. The great thing about these tools is that when you train with them, you learn how to adjust your technique to increase power. I still have my old Impax bag, though it died many years ago... The way the Impax system worked (might be similar to the power cube) was that there was a plexiglass layer in the middle of the padding with an electronic strip that measured the bending force and transmitted this signal to the LCD box. Very primitive, but the forerunner of today's accelerometers. I think this new system is probably much more precise. Because these tools measure the compressive force of your strikes, you get a higher score if the bag is being held by someone heavier -- if you're able to blast someone back with your strike, the force tends to dissipate, reducing the score. Also, if your straight line strikes don't deviate, it transmits a lot more force into the bag. The boxer had a really good way of doing that.

[@cpiper6338]

Yes, we had 2 back in the day. One strapped around a heavy bag (any heavy bag) that measured power and speed (or timing), then later Impax marketed a square focus pad model that the gauge plugged into for use with round kicks, spinning hook kicks, crescent kicks, etc. Fun times!

[@royalbandit8106]

You know what! I like this. Love the message at the end. You clearly have a Martial Arts background 😂

[@n0madc0re]

Practiced TKD for 5 years. One thing we learn quite soon and that might explain the high scores is this : every strike from one side must *also* be mirrored with a pushing force on the opposite side. If for example you do a simple side kick with your right stance (means you start with body facing right, only exposing your left profile to opponent), you have to switch to left stance during the strike (means ending in a reverse side, exposing your right profile), which naturally pushes your left side to the rear. Same for punches. This is why TKD fighters look like dancing while kicking, constantly switching side (or getting back to initial stance, depending on situation). This creates a devastating inertia that adds a lot of force to the receiving end. For that roundhouse right kick in the vid, what we don't see is how the whole left part of the body (leg, hip, torso, arm) all push in the opposite direction. This was the most interesting part of my experience and I've never seen this methodology in my karate and kickboxing years. Taekwondo somehow found an elegant way to marry movement, speed and power. There's also a whole universe of strategic small details during fights like choosing the best stance (left or right) depending on opponent's stance, distance, footsies, faking, forcing combo openers, etc. It's mostly mind games. Olympic fights might be boring to watch for someone who doesn't practice TKD, but when you understand how it works you can see dozens of branching scenarios from one simple foot position switch. It's like chess, it's fascinating. Anyone who love combat should definitely dive into the world of Taekwondo, tips and tricks videos, official fight commentaries etc. It's a pandora box of fun and complexity.

These impact tests are very interesting to me. Have you tried measuring the knife hand strikes on the sensor? Movements like the: 1. Overhand vertical strikes. 2.

[@nightshade7240]

I was always taught that the elbows should be thought of more like a cutting weapon than a blunt force weapon. The techniques with elbows are designed to penetrate into what they hit with the smallest area driving all the force, whereas punches and kicks are generally designed to disperse force through the target for effectiveness. So an elbow will never be as powerful but it can do far more internal damage. Nice to see the ridgehand. Pretty underrated but so versatile. If your boxer friend also rolls his shoulder as he turns his body back into the punch, it will give it even more power because of the ranges of motion involved in bringing it all together.

[@cpiper6338]

I agree with you regarding the concept of elbow strikes. I think what goes wrong here is; when using a softer or less dense target, the person ends up striking more with the forearm rather than the actual elbow (the end of the ulna). Therefore, the force (impact) is spread out over more surface, getting less penetration.

[@leagreenall5972]

Regarding elbows; the one shown was what is called a 'cutter' - fast and cuts like a razorblade around the eye ridge. Hit across the jaw its a knockout and the speed hardness of contact point and all executed in such a short distance and blink of an eye is something pure raw hitting power doesn't take into consideration. But as a Muay Thai ex pro fighter and fight trainer, there is nothing more powerful in close than a 'breaker elbow'. When you have your opponent by the back of the neck and pulling them in as you drive in the elbow. There is no give, and it lives up to its name with breaking anything it contacts. The same with the knee. The guy was terrible at throwing that knee; no thrust, too short, no drive and pulled back, not enough hip movement - and looked like he didn't point his toes to hone the area of the knee to strike more of the cap and not the larger muscle area.

[@spudley_1_325]

If I had to guess how the machine works, it measures how far it moves and the time it takes (distance ÷ time) to get the speed. Change in speed ÷ time = acceleration. Acceleration multiplied by the mass of the machine = the force generated in order to move it.

I really relate to the first guy a lot. I'm his weight up to 140 depending on what I'm doing. I apply my aggressive strikes with that exact mindset, but it's not often because I counter fight way more than anything. And his approach plus the whole issue about being light means you need a lot of speed to compensate the lack of weight made me realize why I love using that back kick/spinning sidekick the TKD guy (my first martial art) did so much. It's offensive and defensive when used correctly and adds so much speed and movement without sacrificing much control.

I just enjoyed seeing the different styles. I practiced tkd and jujitsu as a teenager. It wasn't too surprising to see tkd take it in power since it's mainly kicks but power isn't really all your looking for in a fight. Tkd is pretty rigid so a more fluid style trading off power to get in close or move around easier can be very advantageous.

[@electric_boogaloo496]

Great video, here is what I learned 1. Momentum from the body, linear or spinning adds a lot of power to the strikes, which makes sense because when you are standing still while striking, aka, karate punch, the rest of the body can contribute no more than opposing the recoil of the punch/kick when it meets the target. Also seen in other sports, for example in Javelin throw the thrower falls over on purpose to transfer maximum momentum to the javelin. A serve with a jump in tennis is much more powerful than a serve without a jump. 2. Heavier limb hits with more force, duh! 3. Roundhouse beats front kick or side kick because not only are you generating power with your leg and core, but also you are transferring your body's rotational momentum to your target. 4. The spinning back kick not only has the help from the body's spinning momentum, it also add the power of the glutes to the kick to generate much more power than the roundhouse. Quads and glutes combined have enough power that any person without a disability can jump on one leg. They are the biggest muscles in the body, no wonder that power combined with the spinning momentum of the body added to the kick can knock opponents off their feet. 5. It would be interesting to see the power difference of a stationary back kick to a front or a side kick.

[@vixxcelacea2778]

Seeing you break it down based on what muscle regions would on their own generate a lot more power, but also adding the momentum made more sense as to why a moving back kick could generate so much more power. Even though the spin isn't as much momentum as the tornado. It's because it's using two main muscle areas that are much more powerful AND adding momentum. I think you also hit with the heel or the whole foot from what I could see, so it's also blunt force since it's more solid than say the front.

[@Lo33y_]

So many issues with this main one being weight differences are massive but interesting none the less. Few things about tkd, we have the knife hand as well and it was my go to hand technique for breaking in comps. Only thing is its banned in sparring cause of excessive force. Also i feel it really depends on where you learnt taekwondo and by whom. Our instructor was insane and we did a lot of breaks and high power/ flashy kicks and hands. It was really common for the upper class (red belt up) to have insane drills like 2v1 spars and getting u16s pre blacks to break boards cause he thought it was important to actually know how to defend yourself and theory can only get you so far. In case anyone is curious when it was his turn for the 2v1 he just legged it out the dojo initially and this guy was the breaking champion in the UK. Definitely could have handled it, but just said nope and ran.

Exactly this... If you think about it, the same guy kicking the box when it's stuck to a brick wall is going to score a LOT more than if it was dangling by a rope freely.

I also argue that the hardest hits regardless of martial art always depend on the practitioner's skill, discipline, focus, dedication, attitude, confidence, and willingness to do the blooming work.

However, martial arts are not always defined by the power of their strikes and grappling abilities but also by how well they can uphold the eight codes of the arts: attitude, confidence, cooperation, self-respect, respect for others, dedication, and discipline. Let us thank the amazing Hanshi Jason David Frank aka Tommy Oliver from the Power Rangers franchise for the Eight Codes of the Dragon and for also empowering many martial artists to live by the code.

A big conflation is this is the setup. It's a person holding it. How stiffly they hold it would make a big difference in the force reaction and the instantaneous pressure. If he dampens it by getting knocked off his balance more easily sometimes, it would be a big change to the force reading. I think that could be a part of why there was more variation in the kicking values - the kicks are more likely to be forceful enough to unbalance the person holding it. Ideally the sensor would be held by a set of stiff springs that were the same for everyone.

I think a big reason the power is so inconsistent is that the stronger hits as you said, take more time to apply the force. Since impulse is force/time the total impulse is absorbed by your body instead of straight into the bag/box, leading to higher numbers for roundhouse kicks. If you hit an actual dangling bag you can see which hits are strongest in total energy by how far it moves but the force of something like a roundhouse kick will be higher since the time is lower.

[@joaovictormartinslima6755]

Capoeira!!! AXÉ!! 🔥🔥🔥

[@wertywerty6]

For those still wondering, here's some physics background on hits: First, there's 2 side to a hit: 1- Energy transfered to the target. 2- Pressure on impact. 1) You transfer your energy to an opponent in 2 ways: A) Potential energy (mass * height difference * gravitational acceleration) and B) Kinetic energy ( 1/2 * mass * velocity^2 + rotational kinetic energy terms) 2) The pressure at impact is the contact point with your target where the energy is transfered. Now let's see why the TKD' spinning side kick is so devastating: 1) Even if it is small, the person jumps a little bit (his center of mass elevates). Therefore, he gets a fraction of energy there. 2) Rotation. This is where most of the energy is generated at impact. Here in comparison to other kicking techniques, the rotation of the body is transfered to a linear movement (body's kinetic energy to the kicking leg). In comparison, in a roundhouse kick, your body rotates but you do not transfer as efficiently your rotation to your kicking leg. For example, if you miss your roundhouse kick, you'll certainly continue to spin because your body still had rotational kinetic energy but, in TKD's kick, you would almost be at rest because you transfered most of your rotation to your kick (linear movement). To conclude, this TKD's kick brilliantly transfers the energy of your body (potential + kinetick energy + rotational kinetic energy) to your kicking leg. Moreover, the impact zone is small (being only the side of your foot). This way, it maximize the pressure on impact which results in damaged to your target.

As a TKD black belt myself, this was a real ego boost. I now have "proof" that I am a better fighter than someone who does muay thai (joke)

[@throughthoroughthought8064]

I fully-expected Muay Thai to win and TKD to be last. 🤷‍♂

4:15 I gotta say, Peruca chose the absolute weakest kicks in capoeira. And he definitely could have generated way more power with the "Martelo de Chão" the idea of the movement is to drive the whole weight of the body into the attack. He was controlling it.

2:15 what the dog doin

[@zinebbarni8541]

I just believe that anyone that has mastered something can break your bones, thanks for the video, I really appreciate all the tips each one was saying about how to hit harder

[@brettbarager9101]

Ultimately . . . It's is less the art form and more about the artist individually . . .

[@Stark1ller]

That stupid Capoeira music deals more damage to my body than any Capoeira hit.

[@mkcool_]

Capeira is a lot more powerfull than shown in this video is you look into the comments a bit you will see other people saying that too. And ofc you will say smth like that through a screen

[@inpowerenglish]

This turned out to be the complete opposite of what I thought it would be

[@pettersenm]

Fight Science did a similar test years ago. Capoeira had by far the most powerful kick. Guess the results depends on the test subject more than the style

[@vggm5750]

Thanks seth... for saying the truth...that everyone of them is diferent and we learn diferent strategies, and we can learn new forms 👍

[@terbrylewis6400]

@ 5:25 This is sooo nice to see the Capoeira practitioner being able to properly generate that kick from the ground to record the kick power! 😭 For context - I saw a Science show many years ago that tried to do something similar to this vid. When they reached the part of measuring kick strength from four various martial arts, in order to simulate a moving target to hit, the ENTIRE PLATFORM was rocked about! (Looked more like the persons had to try to kick in the middle of an earthquake than a moving target!)
