MMA Altitude Training Device Review – Legit or Hype?

Heard of Altitude Training Simulation Devices?

Lately, I’ve gotten a number of questions about various devices that you put in your mouth or wear over your mouth and/or nose that purport to simulate altitude training my fighters, customers and subscribers.

You might’ve seen people using various devices on YouTube or other places.

When I get multiple questions about something, I know it’s time to roll up my sleeves, pull out my library card and do some down and dirty research.

If you don’t know what I’m talking about, they basically restrict your breathing, which is supposed to simulate training at altitude.

Various claims are made about these devices, such as:

  • Increased lung capacity
  • Improvements to something called your Anaerobic Threshold
  • More energy
  • Improvements in physical and mental endurance and mental focus… and many more.

WARNING: we’re going to get a little technical here, so if you have absolutely no desire to talk science with me, then skip to the Conclusion at the bottom of this article for the answer to the question, “Will using these devices improve my performance?”

Otherwise, into the rabbit hole we go…

The first question you should be asking here is…

“What is Altitude Training and How
Might it be Beneficial for MMA?”

To understand the science behind altitude (elevation) training, you must understand the following definitions; otherwise you’ll be lost at sea without a paddle.

High Altitude Training

[features_box_azure_blue width=”75%” + border=”2px”]

Anaerobic/Lactate Threshold
The intensity of exercise at which your body begins to accumulate lactic acid*; at this point, energy production shifts from aerobic (unlimited energy) to anaerobic energy production (very limited)

*NOTE: this is not entirely correct but I’m not going to waste time here explaining what lactic acid is and what really causes fatigue, the main concept is still the same, so if you’re a science geek getting ready to call me out, don’t bother, it won’t help you, me or anyone else reading this

VO2 Max
The max amount of oxygen your body can make use of for fuel; often used in studies as a test for aerobic fitness, although it’s not often the best indicator of actual sport performance; often expressed as either 50 ml O2/kg bodyweight/min, or 5 L O2/min, either way, HIGHER is BETTER

When the air you breathe contains less oxygen than normal

The stuff you breathe did you really have to click this one? lol; composed of about 78% nitrogen (N2) and 21% oxygen (O2) at every altitude

Refers to elevation above sea level where the air is less dense, and thus contains less oxygen because there are fewer particles in the air overall; % of oxygen remains the same as at sea level; two major variables are manipulated, where you train (High or Low) and where you train (High or Low), thus, the following combinations exist and have been thoroughly studied:

  • Train High Live High (THLH)
  • Train Low Live High (TLLH)
  • Train High Live Low (THLL)
  • Train Low Live Low (TLLL – what most of us do all the time)

Some popular altitudes:
Boulder, Colorado, USA: 1650 m
Whistler, British Columbia, Canada: 652 m
French Alps: 2500 m
If you want to see how exactly how dense air is at a certain altitude, check this link out:[/features_box_azure_blue]

Now that you’ve got the basics let’s talk altitude training…

Altitude training is based on the premise that when you’re at altitude, there’s less oxygen in the air, making exercise a lot harder. The higher you go, the less oxygen there is, the harder exercise is.

altitude training oxygen levels

Because of this, it’s theorized that altitude will force your body to adapt increase your red blood cell (RBC) count and thus improving aerobic performance, delaying onset of anaerobic energy production and improving recovery.

The bottom line is that…

More Red Blood Cells = More Oxygen (to feed your working muscles with)

This is important – remember it, you’ll need this knowledge later.

This is the theory, anyway, but lucky for us, it’s been rigorously tested by scientists from around the world.

Some cool sports science history – altitude training gained huge popularity after the Olympic Games in 1968 which were held in Mexico City1.

Mexico City is at an altitude of 2300 m, so for those athletes who weren’t prepared for this, it was a huge shock and the exercise physiologists were put to work to figure out how to use this to their advantage.

Now, as mentioned in the Altitude definition above, there are 3 main combinations of altitude training that have been studied: Live High Train High, Live Low Train High and Live High Train Low.

With respect to these devices, if it’s supposed to mimic training at altitude and you wear it during your workouts, this would be similar as Live Low Train High (LLTH), since during your workout, you’re ‘training’ at altitude and the rest of the time you’re at your normal altitude.

live low train high at altitude

So we’re going to focus on the studies that test LLTH and forget about the rest.

[For now, maybe if you’re really interested, I’ll discuss the others a future post. Let me know in the Comments if this is something you’d be interested in reading]

In a paper I found titled, “Is Hypoxia Training Good for Muscles and Exercise Performance?”  authors Michael Vogt and Hans Hoppeler from the University of Bern in Switzerland  state quite definitively:

“… A common feature of virtually all studies on “live low–train high” is that hypoxic exposure only during exercise sessions is not sufficient to induce changes in hematologic parameters. Hematocrit and hemoglobin concentrations usually remain unchanged with “live low–train high.”

“What does this mean for YOU as a Mixed Martial
Looking for Peak Performance?

So, do these devices actually increase red blood cell production and improve oxygen delivery to your working muscles as claimed?

When Vogt and Hoppeler talk about “hematocrit” and “hemoglobin”, they’re basically talking about RBCs. For your purposes, hematocrit = hemoglobin = RBCs. For each, more is better.

If you don’t know what RBCs, hematocrit or hemoglobin are, here are some definitions:

[features_box_azure_blue width=”75%” + border=”2px”]Red Blood Cells

Cells in your body that are responsible for transporting oxygen where required; the more red blood cells (RBCs) you have, the more oxygen you can transport to working muscles


Refers to the % of total blood that is made up of RBCs; more is better (to a point, if your blood gets too ‘thick’ you could die but this will never happen through training, only drugs)


The specific component of a RBC that carries the oxygen.

Let’s do an analogy – it’s kind of like if you were carrying a backpack that had your boxing gloves in them, you are the RBC and yes, you’re carrying your boxing gloves, but to be more precise, your backpack is actually carrying your gloves…

Well, your backpack is like Hemoglobin. Get it?

If not, I don’t blame you, the analogy sucked. Leave me alone – it’s late.[/features_box_azure_blue]

So Vogt and Hoppeler state that LLTH (altitude training) does NOT improve red blood cell paramaters, which means that performance does not improve either. But let’s look at some hard data, just to make sure, OK?

There are no studies on MMA specifically, so I had to search LONG and HARD to find something that would at least come close.

This took me FOREVER, because most of these altitude studies are done on endurance sport athlete such as runners, cyclists and cross-country skiers.

But lo and behold, I stumbled upon one, a moment before my eyes were about to explode from reading these cryptic journal articles all day. Scientists reading this – why can’t you write in normal English!

training mask research

How I looked and felt slaving through journal articles on my computer.

AND this is where we have today’s cliffhanger… :P

I put a lot of work into this article, as you can tell from this first half…

So if you want the Conclusion, I want to see 100 Comments letting me know that you want to see it, otherwise, into the vault it goes!

I’m 100% serious – if we don’t get at least 100 Comments, you won’t see Part II.

I wonder if
3 years 9 months ago

Will my hill sprint training be more challenging now?

3 years 9 months ago

I’m going to go out on a limb and based on the Single scientific opinion you referenced from Switzerland, that the mask is just another gimick. Unless of course you live at high altitudes and train in a mask at low altitudes? But hey, whats the answer? lol

Maybe it's hype
3 years 9 months ago

I’d like to know especially with all the PED use going on in MMA.

3 years 9 months ago

i want to know

3 years 9 months ago

come on, let us know what you have found, eric. i bought a mask only a few weeks ago and i think i already get an increase in condition. that´s what i´m feeling. placebo??

by the way, thanks a lot for your great statemants and videos. we really appreciate each of them.

Kind Regards from germany

Good article Eric. I say LHTL. live high because altitude builds RBS’s which will increase aerobic capacity and train low because you can train more intensely at lower altitudes. Short bouts with the mask will starve the body of O2 and decrease training intensity and will only be useful if you’re trying to mimic being gassed at the end of the fight.

Tony Ricci
3 years 9 months ago

The mask won’t change the the partial pressure of oxygen at all so it won’t change your H&H much either. I believe the mask’s main value is to improve the mechanical ease of breathing (when breathing intensely) by overloading the accessory muscles and the diaphragm (maybe). It would be intriguing to see if the mask also improves the airway structure’s resistance to changes while breathing at extreme airflow rates. In such cases a partial collapse (narrowing) of airways may occur, hence then wheezing one can induce in oneself simply by forcefully exhaling hard. Good article though…..looking forward to the rest. I imagine that there is a psychological benefit as well…..simply due to the comparative ease of working without the mask during competition.

3 years 9 months ago

I believe it takes approx 2wks for the body to truly acclimate to altitude. I am not sure, but either 1400 or 1900 ft above sea level seems to ring in my head as the cut off. So the LLTH would be insufficient to increase erythropoietin which is responsible for RBC production…..right. Now psychologicallly, getting used to sucking for air might help if one gets caught in a rear naked choke.

3 years 9 months ago

I think it’s actually longer for the body to fully adjust to altitude in this sense, because the body needs to kick out more red blood cells, which takes a while. If memory serves correct, it’s closer to 4 weeks to fully compensate.
It only takes about 1-2 weeks for your body’s pH to adjust to altitude, which works as follows:

– you breath faster because there’s less oxygen (O2) around in the atmosphere
– by breathing faster, you get rid of more carbon dioxide (CO2)
– CO2 and bicarb (HCO3-) are the main ways that your body balances it’s pH. CO2 is the acid, HCO3- is the alkali (base)
– as your lungs get rid of more CO2, your kidneys begin to get rid of more bicarb to balance it out, a process that takes about a week to equal out (or get close to it, you never fully come back to your normal pH)
– once you’ve made enough red blood cells to carry the O2 that you need, you don’t have to breath as fast and the process swings back in the other direction

I think it’s also important to know that bicarb helps you clear lactic acid (the stuff that makes your muscles burn when you’re doing anaerobic exercise), and if you’re at the point in this cycle where you’re kidneys have dumped a bunch of bicarb to balance your pH and you haven’t made enough RBCs to make up for the O2 difference, you’re going to have more trouble clearing lactic acid. I can’t remember the guy’s name, but there was an American miler who set himself up for this perfectly at the ’68 Games in Mexico City: showed up about a week before his race to “get acclimated”, his body adjusted for pH, but didn’t have time to make new RBCs, and he promptly finished 12th in his race.

Anyways, Rob, you are correct that this device isn’t going to stimulate erythropoietin production. Same goes for the LLTH philosophy. I think you might be better off if you wore this thing for daily activities and for sleeping. That would have a better chance of convincing your body that there’s not enough O2 around and perhaps increase erythropoietin production. I’m thinking it’s probably not worth it to drop 90 bucks for this thing…

Are you saying none of those sports scientists studied Judo or wrestling athletes but we went and stuck them in the US Olympic training facility in Colorado anyway?

Too bad science is sooo expensive . . .

I need to know!!!!! :-)

I have been looking at this for a while know but without the knowledge and experience like you guys have most of the information might as well be in shorthand!

Please, Please, Please release the answer :-).

I look forward to reading it soon!

3 years 9 months ago

What is the answer? I was just yesterday looking into buying one of these.

3 years 9 months ago

What’s the answer man? Keep the articles coming… It’s all great info

3 years 9 months ago

Hey Eric,

Please release your results regarding these training devices. It’s good information if I ever decide to take my training to the next level, and it will let me know if certain coaches on TUF are teaching the contestants the correct training techniques.

3 years 9 months ago

I’m going to hazard a guess that the mask does provide some benefit, but only when used intermittently at rest. For true, altitude-like training, the better option would be sleepingin a hypoxic tent.

3 years 9 months ago

come on bro tell us

………….Even Chuck Liddell said high altitiude training is B.S.

3 years 9 months ago

I don’t really care to use it, but I’d like to know whether it is worth it!!

3 years 9 months ago

so what is the conclusion?

3 years 9 months ago

I thought this was something that seemed too good to be true, esp at the price point, I also figured that you not only needed to Train but LIVE in High Altitude to really see results. Adaption like that wouldnt take place by just spending 4 hours a day at high altitude, simulated or real I would think.

Thanks Eric!

3 years 9 months ago

So what is the final verdict?

3 years 9 months ago

Reviews on Amazon are mixed, so it would be great to get your thoughts on the product.

3 years 9 months ago

I’m thinking of moding a rubber half mask w/ filters (like the ones used for liquid respiriable contaminants). They are quite a bit cheaper and there is nothing over your eyes that could get fogged up (I sweat alot).
Let’s hear the final verdict on this self induced hypoxic training device. Is it really worth my while?

3 years 9 months ago

I’d like to know whether my performance should improve after a skiing trip as well. If I live at 1700m high skiing 6-7 hours a day for a week, will it make any significant change in my RBC density? Because I tried it, and I didn’t notice any difference when I trained back home the following day.


3 years 9 months ago

Waiting in anticipation :D

Conclusion please. This is an intriguing article! With all the hype about the altitude training device I want to know if it’s for real or not.

gerry ayers
3 years 9 months ago

My theory: It works for anaerobic but not for aerobic sports. Maybe has something to do with a possible internal trigger? Not sure, but I am intrigued to see the answer.

I would love to hear you final part to this. I am looking at improving my game so this would help

3 years 9 months ago

Part 2 please

Come on Eric i am thinking about buying one of these! I need your input before i spend my money!

3 years 9 months ago

It is a bit too difficult to understand for me but because I wanted to buy one, the answer will be most welcomed…

3 years 9 months ago

Too F!@#$%G funny! Reminds me of the Saturday/Sunday night movies on TV in the early 90’s… TO BE CONTINUED. Bad part is I never did get to see the other half of the movies. Oh well, maybe I’ll get to read the “PART TWO” of this blog. If not in 20 years something may trigger my memories and make me think back to the time I read a half post on a blog referring to training with a retro WW2 gas mask! The funny thing is I really don’t care if the “MASK” works or not, the only time I would wear one would be if I was being attacked by some kind of chemical warfare! Kudos to the first half of the post.

3 years 9 months ago

Well, we got the 100+ Comments so hopefully you’ll be back….

Oh yeah I would very much like to know if it works. I see alot of athletes using this device if not make shift ones like it.

3 years 9 months ago

Train slow, fight slow that’s what you will get as your end result that’s why training high living low will never work that’s my take on the mask amyway. The only benefit I see is it may induce an adrenal stress factor (fuck I cant breath) that mimics that of a fight, which might prepare someone for that oh so common feeling.
Besides that it’s simply a bad look.

3 years 9 months ago

Post the second half. You got my attention then shot me down. Not cool.

3 years 9 months ago

You’ll get over it. :)

Even assuming it did work, I’d wait for the model that didn’t have full-face coverage which cuts down visibility 80% and increases facial sweat and nerdiness 1000%.

Hey Eric,

I literally just woke up 10 mins ago and was checking my emails on my phone. When I saw these I knew I had to comment. The trainers at my Kickboxing gym and I have been discussing whether to get one of these or not. I trust your reviews and can’t wait to hear what you’ve come up with. Thanks for everything.

PS this my first post, that’s shows how much I need that answer. Keep up the great work warrior.

3 years 9 months ago

it would be interesting to know about the other forms of altitude training, maybe if you wore the mask to bed it would have a greater effect on your red blood cell count and would freak the hell out of your partner.

Hi Eric,

Another quality post from you, with some realy good info. It would be awsome to see part 2 on this subject, as was thinking about investing in this product. Anything that can potentially give you the edge over your opponent has got to be a good thing right? Would also like to see the info you got on the live high train high & the live high train low princeples.

Virgil Tanner
3 years 9 months ago

I like when you do the science. My undergrad is in biochem, so I eat that stuff up.

The “leave 100 comments” thing sounds like Joel Marion, whose work I like. But I hate this leave-me-some-comments game. I am sure it has some business or marketing function, but it sounds a little like when middle schoolers beg for compliments or high school girls try to get all their friends to say they are pretty. I am sure that’s not what you’re doing, but fighter to fighter, it just feels a little unbecoming.

Is there another way you can accomplish the same business/marketing goal?

Peace, and thanks for your work. Yours is the only training email I read, besides occasionally the Bodyweightcoach guys. Keep up the good work.

I’ll hold my breath until I get 5 million dollars ! Here’s an idea, muscle-heads, close your mouth while you workout. Put earplugs in your nose, WHAT’S THE DIFFERENCE? I’m amazed this has so many people champing at the bit for answers. I’ll bet someone is working on an endorsement deal before telling everyone this will make you last longer in bed. SNAKE OIL ANYONE?

3 years 9 months ago

Hey Virgil, good call, yeah I’ve seen Joel do this…

Basically, it helps Google see that people are spending time here on this site, helping it rank higher… That’s why I do it…

Plus, it’s fun to interact sometimes and get feedback about posts that are interesting, so I know what to write about further… If only 30 people left comments, I wouldn’t spend another 8 hours researching, writing and editing Part II, it’s democracy at work my friend.

Not Cool but reguardless I still love the mask teaches u work thur fatigue
Which happens sooner

jason griggs
3 years 9 months ago

From my personal experience I find that it does help with my cardio for mma, especially because I have major sinus problems that when i workout my sinuses block to the point where I can barely breathe through my nose at all. So i find that it does help, I will probably be proven wrong but it’s just a personal observation.
I really would like to know wether this is all in my head or if it actually does work.

3 years 9 months ago

PLEASE TELL US! I was really interested in hypoxia training when Wanderlei started it, but he got so slow. Stronger, but slower. I hope in your next article you include answers to both claims too! I was born with asthma and have overcome it somehow, so I’m curious to see if this mask can help lung capacity too. (I can’t see why not, in marching band they made us do lung exercises while marching to be able to hold long notes while marching. I played tuba, so I quite, but that’s beside the point.)
