That "karate" guy who did the front kick is Taekwondo Master Simon Rhee and in his prime, he was probably the most badass guy on that stage. At the time of this recording, he was pushing 50+ years old. Probably why he did a front kick. His brother Phillip Rhee is amazing as well. They were in the movie The Best of the Best together.

Anyway, we would spar with TKD practitioners one or twice a month to teach us how to attack and defend people with other skills. TKD guys are insanely fast. There was one fighter who had a "slap kick." He would "slap" your bare arm with his foot and leave toe prints. It wasn't a deep bruise like a normal kick might leave but it was so fast it pretty much landed at will, and it was very painful. I winced when I watched this guy kick the bag in the video.

You'll also notice Bren's body is leaning back further than your typical Round kick. So perhaps Bren did this on purpose. I've tried this kick, but I'm not Bren. Bren probably had insane Hip Dexterity when this was made which allowed him to throw a very quick Round Kick because Speed = Power. It sucks that we didn't get to see the Karateka throw a Mawashi Geri.
@@Tkdm5 That's why I try to do the Kick more slower and relaxed. It's like Tennis, you don't muscle the racquet, you let the racquet do most of the work. You should look at Rafael Nadal's fore hand. It's like a whip.
Kwonkicker has a great video explaining what we in old school TKD usually call "jump powered round kicks" he's pulling with his front leg and then actually driving back down into the floor like he's jumping through the bag.
I like this one. Sensei Seth is examining one of the few empirical studies on martial arts and power of techniques. I think those natgeo shows did a great job, with some accuracy. Sensei Seth is demonstrating the importance of "Peer review". Empirical research requires peer review to explore the validity and limitations of studies and their findings! ALL empirical studies should discuss both their findings and the limitations of their research, and natgeo did not do the latter. Keep it up Sensei!!
I’ve realized that the heavier/stiffer the target is, the more it’s sensitive to mass. The lighter/more flexible, the more sensitive to speed. For example, a double end bag does care how much mass you throw in, it’s all dependent on speed. A slap will make it go crazy more than a knee.
that's mostly due to surface area and elasticity... you can actually affect the dbl ended bag more with a slipping grip than a knee strike due to the same forces at work. (same with throwing an air filled balloon, vs holding it with your thumb, middle, ring, and pinky fingers and poking your fore finger into it, then letting go with the other fingers... it goes further with the fingers letting go than throwing)
I'd really like to see you react to the old "Human Weapon" series. How bullshido are the "ancient arts" they encounter, how serious are the techniques and what are your takes on the final fights. They do some of the Fight Science-style animations, but the "hosts" are real people and the locations are sometimes quite gorgeous.
You can also see in the video that TKD uses the top of the foot, whereas MT uses the shin. More speed and power on the end of a lever, but also more delicate bones in this case so I suppose it's another tradeoff. Cool vid, Sensei Seth!
The Tae Kwan Do practitioner is Simon Rhee, who was my Tae Kwan Do teacher when I was 5 years old in Woodland Hills, California. Simon Rhee is also an award winning fight choreographer that received an award for fight choreography of the blockbuster movie Inception (Ken Watanabe, Leonardo Dicaprio). Thank you for sharing this.
The artists themselves chose the kick they wanted to use. If I remember correctly, Karate guy picked the front kick because it's in a straight line as opposed to the arc that the round kicks are. Straight line is faster = more force.(according to him)
@@houseofaction I myself have a lot of TKD experience... but I found out my teacher/school used tons of traditional karate in stances, forms, and moves. I think he might have done similar.
Yeah, maybe he didn't understand the physics of rotation/torque? Well, even though the experimental set up was rather flawed, it was an interesting video.
KAPWERAH KICK! Btw I an subbing to this channel for actually putting some respek on tkd. I think the power may also have to do with the smaller surface area making contact with the bag. With the Muay Thai roundhouse the force is spread out over a large portion of his shin. FROM THERE IT’S SIMPLE MATHEMATICS!
Asking about how much energy 1800 ft-lbf is: a 7.62x39 from an AKM will have about 2000 ft-lbf as it exits the muzzle, and a 5.56x45 from an AR-15 will have about 1750 ft-lbf when it does. If you're wearing level 4 plate armor and get hit by one of those rounds so it dumps its energy on your surface instead of poking a hole through you with it, that's what the capoeira kick feels like. The karate guy's front kick was comparable to a 9mm.
I’m not a capoeira guy but I have trained with Mestre Kinha from Capoeira Besouro and I can tell you now that Capoeira has the most advanced kicking curriculum and most unique sweeps in martial arts, far more advanced then any other stand up martial arts system. Second to Capoeira I’d say Taekwondo has a far more advanced kicking curriculum then any other martial arts. If you’ve seen Larate from the 20s and 1930s you’d see that the kicks utilized today in karate were not even present yet. With that being said as a Gung fu and Kenpo man I still say Capoeira has the strongest kicks. Additionally to that fact, how they land after a kick is landed or missed is out of strategy not out of flaw and they are not only comfortable fighting from Those positions but extremely effective in those positions.
hahahahahahahahaha this is funny shit, they do not have the most advanced kicks, and crowder is a freak of nature. most Capoeria players are slow as shit compared to crowder and are no where as large either. TKD literally has the most powerful kicks on earth
The TKD kick uses both legs to thrust the body forward (just before the kick). This allows the power of both legs and body weight to add power to the kick. The support legs quickly returns to the ground (allowing a fast kick recovery).
I admit, I've been practicing TKD since the late 80s (back in the so-called Power Era) and while TKD is indeed designed for speed rather than power, the math seems a bit off. After all, a Tornado kick or Roundhouse would have done better than a damn front kick. Then again, what can you expect from a program from the NatGeo, who are notoriously reckless with their findings? After all, Lemmings DONT commit mass suicide! Given that Seth has experts in Muay T, TKD, Karate & Capoeria, he could easily arrange to have the record set straight--he could even add arts like Jujitsu, Wing Chun & JKD.
i remember trying to have this very same discussion on this video with friends of mine back when I had only trained in karate and people thought my opinion was super biased. Basically, all the same points you brought up. The guys are different sizes, the kicks are all a different kick, all hit the body differently based on the size of the impact (ball of the foot vs an entire shin), where they hit, etc. Basically, it's a nifty video but by no means actually covers who is better or which kick is better or which one is most effective in a fight.
The confusion part is actually makes sense for Capoeira because it was made to resemble a dance too, so slaves wouldn't get caught by owners while practicing.
It's funny I turned the video off full screen, you said "I notice you're watching, subscribe", I checked and clicked subscribe and you said "thank you". Nice timing.
The funny thing is the Taekwondo didn't win lol they announced at the end that they actually secretly measured one more thing which was velocity which Capoeira won.
Fight science was about as far away from science as you can get. I'm sure I watched 1 clip where they had a knee as the strongest kick instead of comparing knees from all the guys.
3:12 - it's funny, because "martelo de negativa" literally means "hammer of refusal". But then I found out that "negativa" in capoeira means like "dodge" or "squat". Great video, great fan! Cheers from Brazil!
If this show was about guns, they’d compare a bazooka to a sniper rifle by using one to shoot a steak from a mile away and the other to shoot an SUV at point blank, then conclude one is obviously more powerful with a bunch of random numbers and unrelated equations
Your guess about the TKD kick is right. One of the main things we learn to do with any type of turning kick is to not keep our other foot on the floor, because that slows the kick down due to friction between the foot and ground as well as it gives an "anchor" to the body's center of mass. If the Muay Thai guy added that same thing to his kick, I think he would actually have both the fastest and strongest kick. Also, TKD didn't "win" anything other than saying that its way of performing a roundhouse kick is the best for speed and power (not including Karate because for some reason the guy did a front kick) in this specific test, so on a stationary heavy bag. And I'm saying that as someone who does believe that TKD does have the overall best kicking technique (at least ITF TKD does, not the Olympic WT TKD).
I pushed the like button as soon as you said"I hate it! and it's wrong". Other than the measurment test itself,there was not any scientific method behind.No weight categories , not enough speciments to each category/art , techniques were totaly diffent in each art. Great analysis Seth!
Hey Seth, I'm pretty sure another thing about the taekwondo kick is how they use body mechanics and leverage with the rotation of the hips. You are essentially pushing/pulling off the ground, then rotating your hips, and extending the leg as a lever, same as any kick. I think that ye specific motion that taek uses is what gives it that extra force with less motion.
The karate guy is Simon Rhee, brother of Philip Rhee... They both starred in one of the best martial arts movies ever created, "The Best of the Best" - no pun intended :D... You need to make a reaction vid about their finale fight, and also about Philip Rhee's Tommy character, when he fights preliminaries - one of the sickest footworks I've seen in a movie
Regardless if Bren's kick was actually stronger or not, you gotta admit his technique was beautiful. I love the way he starts a circular motion with his upper body like a kyokushin kick, opens his hips up like a thai kick, then sinks back down as it lands.
I've been waiting almost a decade for a martial artist to react to the dubious "Fight Science" series. Aside from the horrible research methodology (I'm a science nerd), letting each stylist choose different techniques didn't make sense if they're doing comparison. And the other episodes just got worse LOL.
@@houseofaction umm... NO, it doesn't make sense if you're calling what you are doing "science." Among other things in your research, you're supposed to hold all variables constant, except for the independent variable.
I have to share this story. I was just watching this video and my daughter, who has non verbal autism, came and hit the back arrow to rewatch the part where you were climbing on the chair. She then took my phone and watched it over and over again. I think it was the sound that was playing while you were climbing. She likes tapping things. It’s a stim for her. I got a good laugh listening to it over and over. Especially, because you said “don’t do karate like that”. Haha. I practice karate. 😂
That round kick was so powerful. the only problem with round kicks is that there is not alot of penatrating force no matter the power. I have very powerful kicks but no matter how hard I kick I can't move my opponent. even though I've Broken legs with little effort. So if I was going to label a most devastating kick it would be a step spin hook kick. Though it's probably one of the hardest kicks to land due to speed and inability to get both eyes on your target. Once your heel makes full contact try not to unalive your opponent.
Sensei Seth: Why are they pronouncing it “Cap-where-uh?” Also Seth: “Kuh-Raw-Dee” Lol tbh, I think most people don’t want to seem like a total nerd saying it in the accent, like Ross from friends with his “ka-da-teh!”
The biggest difference between the muy Thai and Taekwondo kicks is the point of contact. They are likely measuring the speed at the same place but everyone seems to miss that the farther away from the centrifuge u measure the force then the more force u will measure, even if they are swinging the same weight at the same speed.
The Tae Kwon Do fighter keeps most of his momentum because of that little elevation of the back foot. The Muay Thai Fighter's kick was similar is attack, but keeping his toes on the ground as a pivot creates some friction in the twist, slowing down his kick. TKD is also centered around rapid kicks, so his fast twitch muscles have to be on another level.
Muay Thai guy kicked with his shin, which obviously is a significantly harder and more devastating bone to land with, but the Taekwondo guy kicked with his foot. Perhaps with this testing method of solely using the mass and acceleration to calculate, "who won" the extra amount of whip and distance between landing with the foot as opposed to shin skews the numbers a bit...
The f=ma formula only comes into play in calculating the force on the bag is when the leg is in contact with bag, and "a" in that case would actually be the deceleration of the leg or more precisely the deceleration of the rotational motion of the whole body. The calculation of the force on the bag has nothing directly to do with the initial acceleration of the leg or more precisely the rotational acceleration of the whole body to reach the max speed of the kick.
I didn't know for a long time that there were more episodes of this. The only episode I saw had ninjutsu, boxing, Brent was there to represent taekwondo and for some reason they gave him the katana to swing around. I miss the 2000s, maybe it's just coz I was at the peak of my training in the latter half but martial arts seemed to be most mainstream and popular around the mids, lot of stuff on telly about it. Twas a good time to be part of the scene
I will say it to the day I die. The "best Martial art" is the martial art that works best for you. There is no way to directly compare all of the martial arts fairly and objectively.
LOL! So, two things, boss! First, I did subscribe, good luck with the new channel! Second, i could tell it really hurt you to give those props to TKD. You really should do a whole segment of Sensei Seth Reacts for KwonKickers' videos! You could make that whole thing hilarious! Then have a collab with him on your main!
Whats funny is that they use people who are about the same size but strength isn’t entirely dependent on size so they can definitely be stronger the other ones so come on National Geographic this just aint good
You get a like for explaining the muay thai round house kick, even though i do kyokushin this is really goint to help me cuz i am not so good at kicking since i just did boxing before i started Karate! Thank you!
Seth says he’s a child meanwhile I finished the video minutes ago and I’m still laughing at “The Brazilian martial art Cap Where uh” 🤣 from the beginning of the video
Very beautiful, interesting and useful videos. Your channel is number 1 in the world of martial arts. I hope for more videos about kudo karate .ashihara karate and enshin karate
Seth.. the Capoeira kick is basically Miagi Do's Crane Kick, just done from a crouching position and as a roundhouse .. hope this helps with any mental blocks
The Ultimate MMA fighter would be -BJJ for ground -Capoeira from ground to stand -Muaythai for stand Which should used 30 year to master it all lol. And when they start testing it on unstable ground Muaythai kick stay strong
I think the way to understand this is through energy. The energy that hits the bag is 0.5*m1*v1^2 The bag will gain energy as 0.5*m2*v2^2 + waste (like friction, coefficient of restitution of the bag etc). So: 0.5 m1 v1^2 = 0.5 m2 v2^2 + waste With higher speed the bag will gain more energy (assuming mass is about the same) faster because of the squared velocity. The F=ma is not about accelerating your kick but rather what acceleration the bag gets from your kick, so the energy equations are more enlightening than the F=ma equation. You'll gain more energy faster with more velocity then you'll get by adding more mass.
I'm a fan of your videos. But just so anyone who reads this knows. The guy performing the front kick is Simon Rhee, from Best of the best.they had a taekwondo guy impersonate the karate style.
I feel like the reason the TWD guy had the fastest kick is because as he kicks he also is also trying to spin his body like a top, if he missed he would spin 360 degrees, compared to the muay thai guy who only pivots of his front foot, if he missed he would only go 90 degrees at most
9:24 the way I see it the capoeira kick is basically dropping down your body parallel to the ground in order to basically socker kick your opponent which is a very cool idea. A socker kick to the body is very devastating but it is indeed easier to drop yourself rather than try to drop your opponent so he ends up on all fours so you can kick him.
I remember watching these shows when I was still in school and even then I thought all the "science" was a little hokey. There's so much variable to even be able to compare them fairly. There's even a weapons comparison one where they had the TKD guy (in TKD uniform) to demonstrate the KATANA!
I can explain why taekwondo won. It's because taekwondo DOES push off the back foot, then we AlSO pull from the front foot so we gain energy from BOTH legs which maximizes the acceleration. That's why taekwondo kicks have more force. Mass is relatively fixed by body weight. Muay Thai kicks however have more momentum because they tend to emphasize mass. Thanks for visiting my TED talk
Karate BB with cross training but I started out in TKD as a kid. the TKD "Power roundhouse" has a fairly simple principal: the more weight supported by your standing leg, the less of you weight is being driven into the kick. You can try this yourself simply by coming up higher than normal onto your toes during the pivot. You're trying to harness both your momentum, your mass, and some gravity to "sit on the kick" so high toes in the pivot and strike as your let your weight off of your toes so the pressure on that standing foot is momentarily reduced to almost nothing.
Thats a pretty cool shirt Seth, i wonder where you got it from......Also its so weird that they have Karate do a front kick while everyone else does a roundhouse style kick
Taekwondo kicks are extremely powerful when applied by an experienced practitioner and with the aim of producing damage. The false perception that many have of Taekwondo kicking techniques being supposedly weak comes from a superficial analysis of competitions in which athletes focus on volume and accuracy rather than power. Videos like this and Joe Rogan's are important to break this stereotype. Taekwondo kicks are as strong or even stronger than those of other styles such as Karate and Muay Thai, what happens is that most practitioners do not execute the kicks to the fullest of their potential due to bad habits from pure sportive/pointing training. In the end of the day is all about the aplication of the techniques.
no ones gonna say that taekwondo players arent insanely powerful kickers, problem is they train to kick, not to fight. a muay thai guy and even untrained people could probably mop the floor with a taekwondo guy, it needs heavy supplementation from the other arts
@@paultav556 As a former TKD practitioner I agree that TKD is not a complete martial art. But saying you don't learn how to fight is a big stretch since on top of all the kicking you are constantly practicing universal concepts like positioning, dodging and footwork. That's the point Antonio was making that the martial art is misinterpreted because of the competitive sports scene.
I remember watching this program years ago, and I was like, “Oh, that’s cool. But isn’t science all about controlled experimentation?” The guys are different weight classes throwing pretty much the same kick, except karate for some reason. They really did Simon Rhee dirty.

Kwonkicker has a great video explaining what we in old school TKD usually call "jump powered round kicks" he's pulling with his front leg and then actually driving back down into the floor like he's jumping through the bag.
That makes a lot of sense,its too damn late for me think physics right now
I like this one. Sensei Seth is examining one of the few empirical studies on martial arts and power of techniques. I think those natgeo shows did a great job, with some accuracy. Sensei Seth is demonstrating the importance of "Peer review". Empirical research requires peer review to explore the validity and limitations of studies and their findings! ALL empirical studies should discuss both their findings and the limitations of their research, and natgeo did not do the latter.
Keep it up Sensei!!
agree - they should also have each thrown about 100 kicks and then the average score taken.
I’ve realized that the heavier/stiffer the target is, the more it’s sensitive to mass. The lighter/more flexible, the more sensitive to speed. For example, a double end bag does care how much mass you throw in, it’s all dependent on speed. A slap will make it go crazy more than a knee.
that's mostly due to surface area and elasticity... you can actually affect the dbl ended bag more with a slipping grip than a knee strike due to the same forces at work. (same with throwing an air filled balloon, vs holding it with your thumb, middle, ring, and pinky fingers and poking your fore finger into it, then letting go with the other fingers... it goes further with the fingers letting go than throwing)
is this why a flick to the nuts hurts so much?!
Dang! Im really glad to see your subscriber count went up pretty good after your last video. Keep it up man I love this format.
I'd really like to see you react to the old "Human Weapon" series. How bullshido are the "ancient arts" they encounter, how serious are the techniques and what are your takes on the final fights. They do some of the Fight Science-style animations, but the "hosts" are real people and the locations are sometimes quite gorgeous.
Is it ok to say that I think I like this channel more than your original one (and I like the original one just fine)? Great video!
Totally fine, as long as you enjoy it 😂🙏
You can also see in the video that TKD uses the top of the foot, whereas MT uses the shin. More speed and power on the end of a lever, but also more delicate bones in this case so I suppose it's another tradeoff.
Cool vid, Sensei Seth!
The Tae Kwan Do practitioner is Simon Rhee, who was my Tae Kwan Do teacher when I was 5 years old in Woodland Hills, California. Simon Rhee is also an award winning fight choreographer that received an award for fight choreography of the blockbuster movie Inception (Ken Watanabe, Leonardo Dicaprio). Thank you for sharing this.
The artists themselves chose the kick they wanted to use. If I remember correctly, Karate guy picked the front kick because it's in a straight line as opposed to the arc that the round kicks are. Straight line is faster = more force.(according to him)
the "karate guy" isn't even a karateka, thats sinmon rhee, grand master in taekwondo he should have used TKD
@@houseofaction I myself have a lot of TKD experience... but I found out my teacher/school used tons of traditional karate in stances, forms, and moves. I think he might have done similar.
Yeah, maybe he didn't understand the physics of rotation/torque? Well, even though the experimental set up was rather flawed, it was an interesting video.
I love that you're rocking the Corridor Digital shirt!
Also, you're right, they should all have thrown roundhouse equivalent kicks.
I'm Brazilian and I was impressed by how perfect your capoeira pronunciation was.
KAPWERAH KICK!
Btw I an subbing to this channel for actually putting some respek on tkd.
I think the power may also have to do with the smaller surface area making contact with the bag. With the Muay Thai roundhouse the force is spread out over a large portion of his shin. FROM THERE IT’S SIMPLE MATHEMATICS!
Asking about how much energy 1800 ft-lbf is: a 7.62x39 from an AKM will have about 2000 ft-lbf as it exits the muzzle, and a 5.56x45 from an AR-15 will have about 1750 ft-lbf when it does. If you're wearing level 4 plate armor and get hit by one of those rounds so it dumps its energy on your surface instead of poking a hole through you with it, that's what the capoeira kick feels like. The karate guy's front kick was comparable to a 9mm.
I’m not a capoeira guy but I have trained with Mestre Kinha from Capoeira Besouro and I can tell you now that Capoeira has the most advanced kicking curriculum and most unique sweeps in martial arts, far more advanced then any other stand up martial arts system.
Second to Capoeira I’d say Taekwondo has a far more advanced kicking curriculum then any other martial arts. If you’ve seen Larate from the 20s and 1930s you’d see that the kicks utilized today in karate were not even present yet.
With that being said as a Gung fu and Kenpo man I still say Capoeira has the strongest kicks.
Additionally to that fact, how they land after a kick is landed or missed is out of strategy not out of flaw and they are not only comfortable fighting from
Those positions but extremely effective in those positions.
hahahahahahahahaha this is funny shit, they do not have the most advanced kicks, and crowder is a freak of nature. most Capoeria players are slow as shit compared to crowder and are no where as large either. TKD literally has the most powerful kicks on earth
The TKD kick uses both legs to thrust the body forward (just before the kick). This allows the power of both legs and body weight to add power to the kick. The support legs quickly returns to the ground (allowing a fast kick recovery).
I love that the Karate guy was Simon Rhee....an iconic Taekwon-Do guy...who's father was a direct student of Gen. Choi....science
Love that you are repping Corridor Digital.
Been subscribed to their website for a while, was subbed to their RUclips since it was the sam and Niko channel!
Holy crap. When I saw “3.4” as your subscribers for a split second I thought it said 3.4m, not 3.4k…
Very underrated channel
I admit, I've been practicing TKD since the late 80s (back in the so-called Power Era) and while TKD is indeed designed for speed rather than power, the math seems a bit off. After all, a Tornado kick or Roundhouse would have done better than a damn front kick. Then again, what can you expect from a program from the NatGeo, who are notoriously reckless with their findings? After all, Lemmings DONT commit mass suicide!
Given that Seth has experts in Muay T, TKD, Karate & Capoeria, he could easily arrange to have the record set straight--he could even add arts like Jujitsu, Wing Chun & JKD.
Legit didnt realize this was a new channel. If you hadnt said it, I wouldnt have noticed. Good shout!
Love your video Sensei Seth. As a practicing taekwondo student who has some karate training, I felt the exact same way. The front kick. Really!!!
i remember trying to have this very same discussion on this video with friends of mine back when I had only trained in karate and people thought my opinion was super biased. Basically, all the same points you brought up. The guys are different sizes, the kicks are all a different kick, all hit the body differently based on the size of the impact (ball of the foot vs an entire shin), where they hit, etc. Basically, it's a nifty video but by no means actually covers who is better or which kick is better or which one is most effective in a fight.
Yeah using a teep was just...weird
Like muay thai has teeps too? Its not even a uniquely karate kick like what capoirara did
They have done the karate guy dirty.
Love how e=mc^2 in the title like they are kicking so hard that fusion happens on the point of contact
The confusion part is actually makes sense for Capoeira because it was made to resemble a dance too, so slaves wouldn't get caught by owners while practicing.
It's funny I turned the video off full screen, you said "I notice you're watching, subscribe", I checked and clicked subscribe and you said "thank you". Nice timing.
It was pretty cool to see the science behind all the kicks... would like to look more into tkd/muay thai myself
The funny thing is the Taekwondo didn't win lol they announced at the end that they actually secretly measured one more thing which was velocity which Capoeira won.
Fight science was about as far away from science as you can get. I'm sure I watched 1 clip where they had a knee as the strongest kick instead of comparing knees from all the guys.
In my 15 years of training mma I can say I’ve never been kicked harder with a roundhouse than I did fighting Muay Thai guys
3:12 - it's funny, because "martelo de negativa" literally means "hammer of refusal". But then I found out that "negativa" in capoeira means like "dodge" or "squat". Great video, great fan! Cheers from Brazil!
Negativa is also seen in Brazilian Jiu-Jitsu. They just don't call it that. Dodging in Capoeira is called esquiva.
I remember watching this so long ago on TV! It's so lame taking people with different body types and weights to test how powerful kicks are.
You should totally test this out with that cube thing!
Imagine a bjj & capoeira practitioner. You think he’s pulling guard and boom kick from hell.
the karate guy isn't even a karateka, he is a Taekwondo black belt Simon Rhee
If this show was about guns, they’d compare a bazooka to a sniper rifle by using one to shoot a steak from a mile away and the other to shoot an SUV at point blank, then conclude one is obviously more powerful with a bunch of random numbers and unrelated equations
You're like a modern RUclips Fight Quest. It's the best.
Why a front kick? Why not... a side kick
💀😭
Wouldn’t help tbh!
Because nobody cares about Robin. We're here for Batman.
Back kick *Fucking dies*
@@senseisethreacts every normal man who has been schoolboy Knows that F=m x a
Why this mistake of karateka ?
why does "Martelo De Negativa" expecially the way Seth said it sound like some kinda cheap Texas beer
Your guess about the TKD kick is right. One of the main things we learn to do with any type of turning kick is to not keep our other foot on the floor, because that slows the kick down due to friction between the foot and ground as well as it gives an "anchor" to the body's center of mass. If the Muay Thai guy added that same thing to his kick, I think he would actually have both the fastest and strongest kick.
Also, TKD didn't "win" anything other than saying that its way of performing a roundhouse kick is the best for speed and power (not including Karate because for some reason the guy did a front kick) in this specific test, so on a stationary heavy bag. And I'm saying that as someone who does believe that TKD does have the overall best kicking technique (at least ITF TKD does, not the Olympic WT TKD).
I pushed the like button as soon as you said"I hate it! and it's wrong". Other than the measurment test itself,there was not any scientific method behind.No weight categories , not enough speciments to each category/art , techniques were totaly diffent in each art. Great analysis Seth!
Hey Seth, I'm pretty sure another thing about the taekwondo kick is how they use body mechanics and leverage with the rotation of the hips. You are essentially pushing/pulling off the ground, then rotating your hips, and extending the leg as a lever, same as any kick. I think that ye specific motion that taek uses is what gives it that extra force with less motion.
The karate guy is Simon Rhee, brother of Philip Rhee... They both starred in one of the best martial arts movies ever created, "The Best of the Best" - no pun intended :D... You need to make a reaction vid about their finale fight, and also about Philip Rhee's Tommy character, when he fights preliminaries - one of the sickest footworks I've seen in a movie
That movie was actually badass with the fights
@@BastardOfTheNorth I know :D
I had my first training session with Bren Foster on the weekend. The guy is amazing!
And btw speaking on tornado kicks you should let your tkd friend who you've done some Videos with throw one into the power cube :D
Regardless if Bren's kick was actually stronger or not, you gotta admit his technique was beautiful. I love the way he starts a circular motion with his upper body like a kyokushin kick, opens his hips up like a thai kick, then sinks back down as it lands.
Nat Geo: Lateef Crowder-
Me: That’s the goddamn Mandalorian
I've been waiting almost a decade for a martial artist to react to the dubious "Fight Science" series. Aside from the horrible research methodology (I'm a science nerd), letting each stylist choose different techniques didn't make sense if they're doing comparison. And the other episodes just got worse LOL.
letting them choose makes more sense in that its supposed to be style vs style not martial artist vs martial artist.
@@houseofaction umm... NO, it doesn't make sense if you're calling what you are doing "science." Among other things in your research, you're supposed to hold all variables constant, except for the independent variable.
I have to share this story. I was just watching this video and my daughter, who has non verbal autism, came and hit the back arrow to rewatch the part where you were climbing on the chair. She then took my phone and watched it over and over again. I think it was the sound that was playing while you were climbing. She likes tapping things. It’s a stim for her. I got a good laugh listening to it over and over. Especially, because you said “don’t do karate like that”. Haha. I practice karate. 😂
Bless ur daughter
I didn’t even notice this was a second channel brother. Right on!
That round kick was so powerful. the only problem with round kicks is that there is not alot of penatrating force no matter the power. I have very powerful kicks but no matter how hard I kick I can't move my opponent. even though I've Broken legs with little effort. So if I was going to label a most devastating kick it would be a step spin hook kick. Though it's probably one of the hardest kicks to land due to speed and inability to get both eyes on your target. Once your heel makes full contact try not to unalive your opponent.
Sensei Seth: Why are they pronouncing it “Cap-where-uh?”
Also Seth: “Kuh-Raw-Dee”
Lol tbh, I think most people don’t want to seem like a total nerd saying it in the accent, like Ross from friends with his “ka-da-teh!”
Lateef crowder’s had such a cool stuntman career. He’s one of the stuntmen for the mandalorian
The reason taekwondo took it was the velosity. Impact force is times two of the mass but times four of the velocity. Speeds the real killer!
The biggest difference between the muy Thai and Taekwondo kicks is the point of contact. They are likely measuring the speed at the same place but everyone seems to miss that the farther away from the centrifuge u measure the force then the more force u will measure, even if they are swinging the same weight at the same speed.
The Tae Kwon Do fighter keeps most of his momentum because of that little elevation of the back foot. The Muay Thai Fighter's kick was similar is attack, but keeping his toes on the ground as a pivot creates some friction in the twist, slowing down his kick. TKD is also centered around rapid kicks, so his fast twitch muscles have to be on another level.
Muay Thai guy kicked with his shin, which obviously is a significantly harder and more devastating bone to land with, but the Taekwondo guy kicked with his foot. Perhaps with this testing method of solely using the mass and acceleration to calculate, "who won" the extra amount of whip and distance between landing with the foot as opposed to shin skews the numbers a bit...
The f=ma formula only comes into play in calculating the force on the bag is when the leg is in contact with bag, and "a" in that case would actually be the deceleration of the leg or more precisely the deceleration of the rotational motion of the whole body. The calculation of the force on the bag has nothing directly to do with the initial acceleration of the leg or more precisely the rotational acceleration of the whole body to reach the max speed of the kick.
I’m subscribing because you’re passionate and good at what information you provide 😂
Not because you told me to but I gave a like for that 😅
I didn't know for a long time that there were more episodes of this. The only episode I saw had ninjutsu, boxing, Brent was there to represent taekwondo and for some reason they gave him the katana to swing around. I miss the 2000s, maybe it's just coz I was at the peak of my training in the latter half but martial arts seemed to be most mainstream and popular around the mids, lot of stuff on telly about it. Twas a good time to be part of the scene
Really nice vid. KEEP GOINGG
I will say it to the day I die. The "best Martial art" is the martial art that works best for you. There is no way to directly compare all of the martial arts fairly and objectively.
LOL! So, two things, boss! First, I did subscribe, good luck with the new channel! Second, i could tell it really hurt you to give those props to TKD. You really should do a whole segment of Sensei Seth Reacts for KwonKickers' videos! You could make that whole thing hilarious! Then have a collab with him on your main!
Whats funny is that they use people who are about the same size but strength isn’t entirely dependent on size so they can definitely be stronger the other ones so come on National Geographic this just aint good
You get a like for explaining the muay thai round house kick, even though i do kyokushin this is really goint to help me cuz i am not so good at kicking since i just did boxing before i started Karate! Thank you!
Seth says he’s a child meanwhile I finished the video minutes ago and I’m still laughing at “The Brazilian martial art Cap Where uh” 🤣 from the beginning of the video
Very beautiful, interesting and useful videos. Your channel is number 1 in the world of martial arts. I hope for more videos about kudo karate .ashihara karate and enshin karate
Seth.. the Capoeira kick is basically Miagi Do's Crane Kick, just done from a crouching position and as a roundhouse .. hope this helps with any mental blocks
5:36 Just learnt that SF = ma formula, a couple of weeks ago in physics class. Just a random fact
I subscribed 1.36s before Sensei Seth told me to. I now think I can predict the future.
Hey I’m one of the nobody’s that asked you to react to this. Thanks! I completely agree with everything you just said. Subscribed 👍
The Ultimate MMA fighter would be
-BJJ for ground
-Capoeira from ground to stand
-Muaythai for stand
Which should used 30 year to master it all lol.
And when they start testing it on unstable ground Muaythai kick stay strong
I love the corridor digital shirt
I think the way to understand this is through energy.
The energy that hits the bag is 0.5*m1*v1^2
The bag will gain energy as 0.5*m2*v2^2 + waste (like friction, coefficient of restitution of the bag etc). So:
0.5 m1 v1^2 = 0.5 m2 v2^2 + waste
With higher speed the bag will gain more energy (assuming mass is about the same) faster because of the squared velocity.
The F=ma is not about accelerating your kick but rather what acceleration the bag gets from your kick, so the energy equations are more enlightening than the F=ma equation. You'll gain more energy faster with more velocity then you'll get by adding more mass.
I'd like to see a physicist react to Sensei Seth's reaction.
I watched both of these specials when they released, and the pronounciation of the words killed me too.
Seth is just angry at this rare Taekwondo w
New channel? I didn't even notice. We follow All of Sensei Seths channels! ....and if you don't...well, Ill kick you in the face!!!
Already watched this clip, and I'm waiting Seth's reaction to the TKD kick 🤭
I'm a fan of your videos. But just so anyone who reads this knows. The guy performing the front kick is Simon Rhee, from Best of the best.they had a taekwondo guy impersonate the karate style.
U were so happy to talk about the front foot pulling lol I teach my students that also I agree back foot pushes front pulls
I watched this as a kid and i feel old now
I feel like the reason the TWD guy had the fastest kick is because as he kicks he also is also trying to spin his body like a top, if he missed he would spin 360 degrees, compared to the muay thai guy who only pivots of his front foot, if he missed he would only go 90 degrees at most
Thanks for saying this is a new channel. Made me check the sub button. Fixed it. In subbed here too.
9:24 the way I see it the capoeira kick is basically dropping down your body parallel to the ground in order to basically socker kick your opponent which is a very cool idea. A socker kick to the body is very devastating but it is indeed easier to drop yourself rather than try to drop your opponent so he ends up on all fours so you can kick him.
I remember watching these shows when I was still in school and even then I thought all the "science" was a little hokey. There's so much variable to even be able to compare them fairly. There's even a weapons comparison one where they had the TKD guy (in TKD uniform) to demonstrate the KATANA!
12:19 “it’s simple math, Maddox”
I can explain why taekwondo won.
It's because taekwondo DOES push off the back foot, then we AlSO pull from the front foot so we gain energy from BOTH legs which maximizes the acceleration. That's why taekwondo kicks have more force. Mass is relatively fixed by body weight. Muay Thai kicks however have more momentum because they tend to emphasize mass. Thanks for visiting my TED talk
I didn't know today was Saturday!
2nd channel drops Wednesdays!
way we love to see it
Karate BB with cross training but I started out in TKD as a kid. the TKD "Power roundhouse" has a fairly simple principal: the more weight supported by your standing leg, the less of you weight is being driven into the kick. You can try this yourself simply by coming up higher than normal onto your toes during the pivot. You're trying to harness both your momentum, your mass, and some gravity to "sit on the kick" so high toes in the pivot and strike as your let your weight off of your toes so the pressure on that standing foot is momentarily reduced to almost nothing.
TKD gave me the habit of kicking and pivoting on my toes. The back leg acting as a launcher for the front leg.
Thats a pretty cool shirt Seth, i wonder where you got it from......Also its so weird that they have Karate do a front kick while everyone else does a roundhouse style kick
I miss that shit. Fight science. I loved every episode they aired.
Taekwondo kicks are extremely powerful when applied by an experienced practitioner and with the aim of producing damage. The false perception that many have of Taekwondo kicking techniques being supposedly weak comes from a superficial analysis of competitions in which athletes focus on volume and accuracy rather than power. Videos like this and Joe Rogan's are important to break this stereotype. Taekwondo kicks are as strong or even stronger than those of other styles such as Karate and Muay Thai, what happens is that most practitioners do not execute the kicks to the fullest of their potential due to bad habits from pure sportive/pointing training. In the end of the day is all about the aplication of the techniques.
no ones gonna say that taekwondo players arent insanely powerful kickers, problem is they train to kick, not to fight. a muay thai guy and even untrained people could probably mop the floor with a taekwondo guy, it needs heavy supplementation from the other arts
@@paultav556 this statement is another excellent example of the stereotypes coming from superficial readings about Taekwondo.
@@paultav556 As a former TKD practitioner I agree that TKD is not a complete martial art. But saying you don't learn how to fight is a big stretch since on top of all the kicking you are constantly practicing universal concepts like positioning, dodging and footwork.
That's the point Antonio was making that the martial art is misinterpreted because of the competitive sports scene.
