Kicks Speed vs. Punches Speed

Can't anyone use Movie Maker or some kind of Video splitters where he/she will split the part where they kick from when he starts to kick till the kick is delivered to the bag and same for the punch???? so we can see it split parts of the second how fast it happens and how long does it take.
 
The faster your kicks and punches come the harder they will hit.
 
I used Video Surgeon and I saw some Kicks took 0.2 sec, 0.3 sec, I think the fastest guys can hit like 0.2 or even 0.18 just as fast as a boxer can punch, of course we are talking about Low and Middle kicks, High Kicks are a different story.

I also used a formula to calculate the kick being delivered, so normally a leg is 20% of the human body I found the weight of the Fighter's leg then we had the force and speed, the speed was 136 Miles per Hour whereas the force was 2300 Pounds I converted this pounds to Newtons and used that momentum formula and it said it takes 0.1 sec to be kicked or the kick to be delivered.

I don't know how true this stuff is but I will try to find better programs that slow down videos even more than Video Surgeon and do it.
 
OK I ran into this Vid where it shows Brandon vera throwing 2 High Kicks, one of those Kicks was delivered at a 0.30 sec and the other was delivered at 0.33, taking into account that Brandon Vera is not even remotely the right person to be tested for kick speed I would say that there are Muay Thai or Kickboxers that can throw a High Kick faster than that, maybe 0.2sec.

Also from all this I would guess that Low kicks and Middle Kicks MUST be way faster than High Kicks since they have less distance to travel they are easier to throw and you don't have to lift the leg as high as when you throw a HK.

 
well if it takes more time to get to the target because of the distance then they are not necessarily faster it is just that they have to travel longer in comparison to punches but low kicks don't have to travel that distance so what about them???

Mechanically, kicks require much more effort which is why they're slower. This is why there's a general rule to set up kicks with punches, even low kicks.

High Kicks for sure not low kicks and middle kicks, you can just throw low kicks and middle kicks just like if u were jabbing, if you go by that logic then you also have to set up a hook or uppercut.

Mechanically or not Mechanically doesn't matter, yes Kicks require more energy that is why you can't kick all the time cuz it is gonna drain you but requiring more energy doesn't really mean the thing should be slower, a F 18 Jet Requires more Energy than a Car but it goes 10 times faster than a car cuz there is a lot of energy to back that shit up.

A kick uses a lot of force and energy which means if you throw something with a lot of energy that means it will go faster and hit harder.
 
Plus go back to the thread I posted a couple of videos that will prove you that Kicks are way faster than Punches.

The Boxer Champ's Punch was measured to be with a speed of something like 35 MPH whereas there were kicks measured with 135 MPHs.
 
High Kicks for sure not low kicks and middle kicks, you can just throw low kicks and middle kicks just like if u were jabbing, if you go by that logic then you also have to set up a hook or uppercut.

Serious? Do you train? What do you train in? I've got see to this whole "you can just throw low kicks and middle kicks just like if u were jabbing" in action. The simple fact that you have to balance on one leg to throw a kick means that kicks generally will take longer to execute than a punch.

In terms of "time to target" measurement, it is a very rare person that can kick faster than they can punch to the same distance.

In terms of the speed of the limb/striking surface itself, I concede that kicks could be as fast, if not faster than punches.
 
I calculated the time that took for the boxer to reach the target ( face of the dummy ) it was 0.19 Sec.

By using his reach as the distance the punch has to travel and his speed of 30 feet/s.

I don't know, these people should make it simple, let a good boxer punch a bag and measure the time that his hand traveled from his starting positioin to the bag and let a good kickboxer kick the bag and measure the time.

I also calculated the time when a kickboxer will deliver a middle kick with the speed of the measured kick of 136 Miles per hour and it said that the middle kick will be delivered in 0.03 which is totally impossible of course I took into account the reach of a kickboxer with his leg 212cm

Your calculation is off. It assumes instantaneous acceleration. Being that the acceleration of his fist isn't constant, you can't even use algebra to solve for it. Your basic kinematics equations are predicated upon "constant" acceleration. You would need calculus to solve for it, and some function relating velocity, and acceleration already.

Of course you could just use video review like Myth Busters does.

Besides the unneeded philosophy I don't really know if u went back to the vids and check them, you can download VIdeo Surgeon or some other Video Editor that will slow down the videos in their parts of the second and u will see how it works.

Just the last video I posted with Brandon Vera showed that Brandon Vera who is not even a Dutch Kickboxer or Muay Thai can Throw a HIGH KICK in 0.3 sec now imagine a low kick or a middle kick, surely it will be half the time of the High Kick since the distance to the target is closer.

Check this vid where George St Pierre can kick Faster than he can punch and so do most of kickboxers or ESPECIALLY Nak Muay Thais, the only people that can punch Faster than THEY can kick are boxers cuz of course they can't kick at all.



That you have to balance yourself before you throw a kick is a bunch of nonsense cuz you can't do that, there is no balance when u throw a kick, u stand in your Muay Thai Stance or Usual Kickboxing stance and u just shoot for a kick and when you throw the kick then you are out of balance since you are in one leg and I don't know if u been following kickboxing or Muay Thai but if u get caught with a punch or push kick while throwing a kick you will be flying like a bag of potatoes.

you don't need to balance yourself when throwing a kick cuz there is no balance once one of your legs is up and thrown with full power to crush bones.

And Yes I have trained Kickboxing before, not a pro but enough, and you don't need to train Kickboxing to know how kickboxing works, if you are careful enough and follow the sport enough u will see how it works.

Maybe High Kicks need to be set a little bit I mean set your balance but Low Kicks don't really need to be set or middle kicks cuz it is easier to throw, the hardest part of throwing a kick is the technique, if you master it you will be throwing kicks very fast and reflexive just like Nak Muay Thais do.

if u ask me I think Nak Muay Thais or Kickboxers can throw low kicks as fast as a boxer can punch if not faster, the leg has bigger muscles uses more energy and in the end the leg has greater impact which usually proves that the Greater the force the kick thrown the greater the power and more speed of course.

If Brandon Vera could throw a High Kick in 0.3s then I don't know about Lumpee Champ Guys or Masato or some other Guys coming from Kickboxing and Muay Thai.


In terms of "time to target" measurement, it is a very rare person that can kick faster than they can punch to the same distance.

Not Really, if we are talking same distance then we are probably not talking about saying that a jab which is the fastest Punch is the same as a High Kick cuz the distance is not the same, obviously.

you have to compare a jab to a Low kick to the leading leg or a Straight Right to a kick on the thighs or a hook to a Kick to the body (mid Section), you can't compare a Jab to a High Kick, that will make no sense.

I think in this terms a kick COULD be even faster than a punch.

In terms of the speed of the limb/striking surface itself, I concede that kicks could be as fast, if not faster than punches.

I don't know if you saw the Vids from Sport and Science where they measured 4 types of Kicks, where a Muay Thai Guy kicked, a Tae Kwan Do, Karateka and Copeira.

The slowest kick was measured with 71 mph whereas the fastest 135mph.

That Light weight Boxing Champ in Sport and Science was also measured and he punched with 30 Feet/s which is not even close to the slowest kick measured.

I am sure in times of Speed that a kick is faster than a punch but the problem is that legs are so big and require much more energy than arms that the First kick will be lightning fast and if u try throwing 10 kicks in a raw the other kicks coming will slow down in speed drastically, and the good thing about punches is that punches won't slow down fast like that.

For instance you can throw 10 kicks the first will be 100 Mph fast the second 80 the 3rd 60 and so on but punches go like 90mph second 90mph 3rd 90mph and maybe the last 3 punches will slow a bit down but not as fast as kicks will slow down.

Anyways we were talking about single thrown kick, a low kick only one and a single thrown Punch cuz usually kicks are set up with punches and considering their speed and power can be used effectively.


Your calculation is off.

That is why I needed someone to correct me and I am grateful that you stopped by this thread to make some stuff clear :)

It assumes instantaneous acceleration. Being that the acceleration of his fist isn't constant, you can't even use algebra to solve for it.


Interesting, can you somehow pull out some numbers from these videos given, I mean the videos back in second page ?

Given Power it generates, the speed and also calculate some kind of reach we maybe be able to calculate something or pull out numbers.

Brandon Vera's HIGH KICK was measured 0.3sec which brings me to if that dude can throw a high kick that fast imagine someone like Souwer, Masato or Muay THai fighter can throw a low or middle kick, I think in this case my calculations would be true.

I am of course not saying I am right I just want to discuss this topic with people like you who ultimately say something worthy like you just did with the acceleration thing and I think you had a good point.

Your basic kinematics equations are predicated upon "constant" acceleration. You would need calculus to solve for it, and some function relating velocity, and acceleration already.

Of course you could just use video review like Myth Busters does.

I think you are up to something but we need to see numbers.

there are the vids, I don't know if u have any kind of VIdeo Editor that will slow down the video REALLY SLOW, I mean REALLY SLOW not just 50%, so of course we can see how long it takes from the time he lifts the foot of the ground to the time he touches the target.

 
Shogun Rua Punches with 25 Mph whereas he kicks with a speed of almost 40 MPH

 
OK so I contacted this Physics professor names Rhett Allain Associate Professor
Ph.D., North Carolina State University and I asked him about the speed of a kick and all this sport and Science stuff that has been going on on TV and so on.

this is what I wrote him

ME:
Greetings professor Allain, I have been searching some random facts about the Science and Physics behind Martial arts, I ran into your blogs and I saw you have some pretty good explanations and you are using formulas to calculate different kicks and stuff like that.

Mr. Allain I was wondering if you could explain me how the physics behind this work and are those data that those guys form Fight and Science or Sport Science accurate, I mean when they measure the PSI of a kick and punch or the speed of a kick and punch, is the measurement of a kick and punch in those commercial shows accurate or not ?????

I was interested to know from these videos I am about to post you if you could tell me what is faster in terms of mph and object displacement, so what is faster in terms of MPH a Punch or a Kick and what is faster in terms of second or parts of the second of the limb displacement.

Kicks seem to be more powerful, more powerful should mean faster since power is gained through acceleration and velocity, isn't it ?

this are the VIdeos I have been watching and they somehow got me confused:

YouTube - ‪Fight Science Kick Test (Capoeira, Karate, Muaythai & Taekwondo)‬‏

YouTube - ‪On Sports Science, Boxer Vs. Snake, Part 2‬‏

YouTube - ‪Sport Science looks at Machida vs Shogun with Brandon Vera‬‏

http://www.youtube.com/watch?v=FzmUhhB8SmA&feature=player_embedded

So this is the case, there is this Boxer who used to be some kind of middle weight Champ and they are comparing the speed of his punch with the speed of a snake bite, they said his punch speed was 30 - 35 feet per second which in MPH will be something like 20 - 25 MPH.

In the videos where they compare kicks of different martial arts they measure kicks with speed of 70 Mp ( slowest one ), and the fastest one was 136 MPH.

Is this true ???? how accurate is this.

it seems that a kick is 4 - 5 times faster than a punch.

Please do some explaining if you have the time for it.

Thank you in Advance :)

Rhett Allain:
Yes, fight science seems to be quite popular. However, there is a problem. How exactly do you quantify an impact? I am not really sure about the best answer. Fight Science seems to continue to make things up (like the speed of the kick). However, these are only part of the equation.

PSI of the kick and stuff like that don't do it either. If I had to measure one thing, it would be the acceleration of the person getting kicked. That is the best I can think of.

As to the question of the speed. I think those speeds seem to be realistic as they are easy to measure.

Hope that helps a little bit.

Rhett

So after watching all those videos from fight and Science I got really confused when I saw that the speed of Chad Dawson's punch which was something over 30 feet/sec which in MPH would be something between 20 - 25 mph and the speed of those guys' kicks was 70mph, 100mph and the fastest 135 mph which means a kick is faster than a punch.

I also posted in this thread where they measure Brandon Veras head kick in terms of seconds and his hick kick was measured 0.3 sec, now taking into account that Brandon Vera is not really the adequate guy to be tested for a high kick and high kicks are usually slower than low and middle kicks due to the distance they have to travel.

I guess low and middle kicks are as fast or even faster than punches.
 
The last emails we exchanged with Professor Rhett Allain:

ME:

So from what I understand you are saying that the VIdeos I sent where they measured the speed of a Kick above 100 MPH and the speed of a punch somewhere 25 - 30 MPH is true and not biased and measured precisely.

if the speed of a Kick is 100 MPH that means that the leg is faster than the arm, isn't it???

I have been talking to many people that watch and some practice Martial Arts and it seems that there is a quite big misconception when it comes to what is faster a Kick or a Punch, most of them say a Punch is faster and when I watched those Videos I saw that a kick seems to be faster.

How do you define faster??? and is what I said true or not???

Thank you one more time :)

Greetings

Rhett Allain:

I think it is safe to say that the foot is faster than the hand (rather than leg and arm) because if the leg is moving in a circular motion, different parts will be going at different speeds. The end will be the fastest. Also, since the leg is longer, it will make the end go faster.

If you are talking about fast as in speed, then the above should be true (and also pretty easy to measure). Some people may say a punch is faster. What they might mean is that it takes a shorter time from start to finish. However, it goes a shorter distance so that might not mean faster.

about him saying that the foot is faster than the whole leg is true because it was proven with Brandon Vera's kick, when he high kicked with the foot it was 0.03 sec faster than when he kicked with his shin.

So in the end the myth is busted, all people here saying kicks are slow were wrong, besides measuring the speed or a kick is an easy thing with those speedometers or accelerometers they tie around the fighter's leg, Kicks from guys relatively not important in the sport of Muay Thai and generally in the kicking department measured 70 MPH up to 135 MPH, Chad Dwason's punch who is a pretty decent boxer was measured 25 MPH max.
 
A punch is a punch and a kick is a kick... you can't compare the two. It's like apples and oranges. Use the right tool for the job.

True, numbers and precise measurements don't lie.

Thanks for stating the obvious, we pretty much knew all this.

I opened this thread to discuss the myth that a Punch is faster than a kick which is totally not true.

As you can see from the videos I've posted and the simple logic the foot/leg is faster than the fist/arm and that was the whole point of the thread.
 
This thread is about the best way to deliver a low blow?

A: knee

 
In my opinion a skilled fighter's punches and kicks travel at about the same speed. Actually the kicks may be traveling faster at point of impact of because the longer distance allows more speed buildup.

The problem though is that a kick travels a much longer distance, so even though it may be traveling at the same speed or faster, it still takes longer than a punch to travel from point A to B. So if your right cross takes .10 sec to travel 2', and your right high kick traveling at the same speed will take .30 sec to travel 6' to the same point of impact.

Because of the longer time in the technique it is easier to see it coming, and makes it appear slower to the eye. Plus, normally there is movement more before a kick is thrown than a punch. Comparing a jab to a teep, you'd have to start your jab with you left arm outstretched overhead, drop it to your shoulder and then fire the jab. Making it travel a lot longer, less direct path. So while your jab may be traveling the same speed, it takes considerably longer time to target.

Did that make any sense? Or am I rambling?

Makes total sense. It'd be like dodging a tennis ball being thrown at you from 10m away would be easy but let them throw it from 1m and you are probably going to get hit. The tennis ball thrown from 10m may well be going faster but you have a lot more time to react to it.
 
I also posted in this thread where they measure Brandon Veras head kick in terms of seconds and his hick kick was measured 0.3 sec, now taking into account that Brandon Vera is not really the adequate guy to be tested for a high kick and high kicks are usually slower than low and middle kicks due to the distance they have to travel.

I guess low and middle kicks are as fast or even faster than punches.

I think something that people should bear in mind is, yes the terminal velocity of a kick is far higher but which one reaches the target first? The punch is much quicker to reach the target.

Taking Brandon Vera's 0.3 sec kick, well Frank Bruno (ex British HW champ) did a punch speed test and it was found his rear cross took 0.1 sec to hit the target which is three times quicker.

So the kick might be moving at a higher speed when it hits the target (head) but the punch got there 3 times as fast. Now measure that time for a low kick and it would be more comparable to the head punch I'd assume.

Makes sense, Head Kicks are slower than Punches, way slower, as you said that Boxer's punch reached the target 3 times faster than the high kick but that is because the Fist is closer to the head.

Middle kicks and Low kicks are as fast as a jab cuz the distance is shorter plus the leg travels with higher speed than the arm which means a Kick will reach the Liver or the inside thigh faster or at the same time as a jab or straight or Cross reaches the head.
