Does Training In An Altitude Mask Really Work?

[@imanjkenpoaviationexpressions]

I used an oximeter to check....My experience is that you get the same amount of oxygen, But your muscles have to work harder therefore you are getting a better workout.

[@nadsham3388]

I actually had great results with that mask. I did moderate exercises with the mask and breathing exercises and it decreased my reliance of an inhaler for my asthma.

[@SalinaMoonfall]

Agreed for those of us with sub-par respiration either from health or lacking strong lungs it does seem like a useful tool to conditioning.

[@geraldfisher6475]

so you are already deprived of oxygen, and you think its a good idea to make that even worse? please just do breathing exercises and cardio.

[@LolaChewie]

@@geraldfisher6475 It doesn’t reduce oxygen. It adds resistance to breathing. It’s like lifting weights for your lungs. I play recreational football/soccer and am getting older (mid 40’s). I can work on my cardiovascular fitness without getting the wear and tear on my body. Imagine getting the heart rate and heavy breathing of sprints or HIIT without needing to do sprints or HIIT. It allows me too keep playing soccer without having my breathing be a limiting factor. The older I get, by body needs more recovery time between heavy workouts. I can build up my lung strength and let my body rest. I still play in the open age category. I’m able to keep playing and keep up players 1/2 my age. While the younger players are breathing heavy and are bent over trying to get more air, I can keep going. You can just wear the mask while doing daily chores.

[@Pneuma77]

Yea thats the only thing I would use it for, my respiratory

[@christiancarter5726]

This reminds me a lot of the 02 Trainer by Bas Rutten. One of the earlier guys to come up with this idea of training

[@thebigbearchasedm]

What I've found when trying air restriction is that it is beneficial for endurance; I usually use a mouthpiece and mask when power lifting(1hour) and for pack training (90lb for 3 miles under an hour.). When you are air restricting your body the primary focus is maintain a steady heart beat and focus on your breathing, so your body is conditioned to fatigue, also your heart and mind can work past the pain and panic of "omg, I'm suffocating!".

I have been using one for well over a month on a daily basis, set to 4880m ASL. I live on the coast. Prior to using this, at 3200m ASL I would really struggle with the altitude. With this I am handling the Altitude with ease.

[@-SimonRiley]

For how long should you use it? Or use it in an intermittent pattern?

[@ChopShackle]

You need to try more than 1 time. Train for something like a month then get back to us for a true experiment. I was telling a customer about my altitude mask. The customer my coworker was serving with an oxygen tank then says "Why would he do that?" My coworker then says "I don't know he's crazy." In the winter it also is mainly used to keep my mouth and nose warm.

[@doylemurphy152]

I used it for two weeks and it helped me on the stair master. I working my way up on the settings and after I do the treadmill for twenty minutes at a nice walk with the mask on. I believe it helped me get use to using the mask. I am doing this to train for the Manitou Incline next summer. I live at 180 ft altitude and trying to work to handle 8,000 ft. Not sure if there is a better way to do it where I live but it was the best idea I have.

[@ronreagan-x5w]

I agree. I'd like to see more long-term results of using this training mask.

[@GlitchChaos]

Late to the show, But, I have trained with a mask and, personally, found it very useful. They don't truly create a high altitude effect. I live in Colorado, elevation of 5,280 ft and spend a lot of time hiking at 10,000+ feet. So, I am very familiar with the effects of altitude training. The huge win for me with these masks, is that it forces me to pay attention to my breathing while under exertion. Just learning to breath more efficiently has had a massive change in my performance. When I use my mask regularly, I notice a dramatic improvement in my hiking ability and how long I can sustain exertion. All said, in my opinion and personal experience, while they don't literally do what is claimed. The results often create the desired effect. Great video!

[@kanehiro4635]

[@kanehiro4635]

@@konradnoises wearing a mask forces you to intake faster and exhale slower, exhaling decreases heart rate while inhaling increases it, if your progressive with your running; the exhaling doesn’t change much in proportion causing you to steady your heart rate in whichever direction depending on your goal for that given day. Personally I inhale with both my mouth and nose at the same time and exhale with my mouth relaxed.

[@konradnoises]

@@kanehiro4635 nice points, loved the advice. do you have some breathing ratio? breathing in for x steps and out for y steps for example. I've been trying many variations and can't seem to find one that truly works.

[@kanehiro4635]

@@konradnoises I feel that amount of proportionality depends on your form,pace,fitness, and goal of your run. I personally don’t count my steps relative to inhale/exhale. I just run and maintain good form, if it’s an aerobic run my HR guides me regardless if I’m breathing off or not but 10/10 times HR gives controlled breathing intention. If your run is recovery you shouldn’t really feel like you’re breathing too much and your HR should remain relatively low. Breathing/hr can be influenced by many factors such as footstrike, cadence, effort, form and fitness. I would recommend getting comfortable being as efficient as you can and then focus on more technical things like breathing per steps.

[@kanehiro4635]

As a Runner with a mask since COVID, I can safely say running with a mask in general does improve fitness…but not directly by simulating altitude but rather tranquility, comfort, and efficiency using your lungs. It does elevate your hr for many days weeks and etc but over a long time you notice it gets easier although you are suffering the same intensity as when you started. Taking off the masks for workouts I’ve always noticed an absurd amount of Fitness I didn’t know I had acquired so I’d say it does work but in a different way

Mark didn't you wear one of those masks for the 1000cal run you did with Heather and Fraser? Well another great video so thanks for sharing.

[@arjl880]

I find that the mask helps me control my breathing rate. You expend so much energy just trying to get so little air while using the mask that it isn't worth hyperventilating...so instead I find myself controlling my breathing for maximum air for each labored breath. When I remove the mask, I find myself breathing at a slower rate for the same workout or speed. It's pretty cool once you get acclimated. My advice: work your way up to it cause it's really difficult the first couple of times you use it.

[@kanehiro4635]

Yeah, been running with a general mask since covid era, and man…. when I take the mask off for workouts the change is there.

You could have covered how masks do not generally effect the partial pressure of the inspired gasses, something that does change when training at altitude.

Can you try to do a long term training using the mask to see is it really works?

[@debbiewyler4048]

Great. As a pulmonologist and triathlete, I’ve thought through this a fair amount when planning for a race at 7000ft(2100m). I have mountains close by and could train at that elevation, but live at the base at about 1000m. Because of the way and time required of exposure to hypoxia, one would not anticipate any significant improvement in altitude acclimation from training high and living low. As you mentioned, the opposite is true. If these masks did decrease the oxygen content, one would also not expect altitude acclimation benefits as you would not have the same stimulus at other times.

[@MTBScotland]

They can affect VT and RCT when combined with HIT training. They won't do anything to increase RBC count as you are still getting the same amount of o2 pressure. You actually need to breath in low 02 concentration (O2 room) or live at altitude.

[@noway2831]

A similar idea is forcing yourself to breathe through just your nose. Breathing through your nose (as opposed to your mouth) has several health benefits as well

[@unclebobs90]

When I ran in school during the winter we were always told to inhale through the nose because it warmed the air instead of going right in your lungs and "shocking" them

[@NerdScriber]

@@unclebobs90Whether you breathe in through the mouth or nose, the air we breathe is warmed and humidified. It’s one of the jobs of the general oropharynx. However, breathing through the nose slightly reduces air flow which increases cardiopulmonary endurance.

[@konradnoises]

Nice video. Pleace make a video on breathing patterns. Analysing several patterns for different paces and heart rates. Would be awesome to see the results, actually based on data, and not just a random coaching tip that says: everyone has it’s own pattern.

[@pokekraze339]

You mentioned oxygen in the air, and how the mask only gets less air to your lungs. That is the same thing that happens with altitude. At sea level or the top of a mountain the percentage of oxygen in the air is still 20.9%. At elevation the air pressure is less, and therefore the partial pressure of oxygen is less, which is what makes it harder for oxygen to diffuse get into your blood.

[@Kamicassie]

I believe the difference is based on the volume. Persentage wise when comparing oxygen at sea level vs at altitude both might make up 20.9%. But at altitude the density of air is lower than at sea level (1.225 kg/m3). This would then in turn mean that per breath you are taking in the same volume of air but the amount of air is less at altitude. The mask however reduces the volume of air that you take in due to the added resistance and your lungs and other muscles working harder for less volume of air

[@markthrelfall3577]

Cassie has beaten me too it. Yep the difference is the volume of air you breathe in remains the same whether you’re at altitude or sea level, but the oxygen content of that air differs

[@pokekraze339]

@@markthrelfall3577 Thanks for the reply, Mark. To me, saying "less" oxygen in the air is misleading. The composition of air is the exact same at sea level and at altitude, but the atmospheric pressure is lower at altitude, meaning the partial pressure of oxygen is lower and hemoglobin won't become saturated. Also, you stated that altitude chambers pump oxygen out of the air, which implies that they are not pumping out nitrogen, carbon dioxide or any other components of the air. Altitude chambers pump normal air out of the room which lowers the air pressure and thus lowers the partial pressure of oxygen.

[@markthrelfall3577]

@@pokekraze339 Of course you are correct, but imagine saying that to all our viewers that haven't studied this. It becomes very long winded, and overwhelming. I think it's fairly obvious that it's not just the oxygen content that differs, but we're focussing on that purely from a hemoglobin and fuelling of muscles stand point. It's also how most literature explain and refer to it. So, this is in no way misleading, but of course I could dig far deeper...but then risk the video becoming incredibly dull!

I’m interested in the usefulness of nasal breathing both for aerobic efficiency and replicating some of the benefits of altitude or hypoxic training .... and whether it is a more sustainable method as you can nose breath 100% of the time

[@maloxi1472]

I've always breathed through my nose, just as a principle... even as the exercises got harder. I thought this was the correct thing to do

[@alsymphony7868]

I know it's been a year, but breathe through your nose. Even when the intensity is up, PREFERABLY you want to maintain a, 4/6 sec inhale, 1 sec pause, 6/8 sec exhale. Where your nose hair is barely moving, that's how less the exhale and inhale is supposed to be, but it's hard to keep that up at higher intensity. There's videos about this on this site. I bike 3 days a week, where 80% of the time I'm biking uphill, I used to breathe through my mouth because it felt right. Saw vids about this and started breathing through nose. First session was really hard, you have to fight your habit, and also it feels you are always out of air. BUT, after the exercise, my body felt better also less tired in general. I also recover very fast in terms of my breathing when doing it through my nose. Normally I would be beat. Don't quote me on what's I'm saying next, these are things I kinda recall from the videos. But breathing through mouth we traditionally used for survival, high stake situations, where there's a predator or we are going for a prey and our instinct kicks in and we breathe through our mouth to take in as much oxygen as possible. while that sounds good, we actually need a set amount of carbon dioxide for our muscles/body to absorb the oxygen. What happens when we do cardio and breathing through mouth is we overload our supply, and our muscle isn't actually taking as much as it should. I'd encourage you to search this up yourself though, like I said these are just things I barely recall. But from experience, it is effective. Can't quite do it on weightlifting though, what I'll do is inbetween sets I'll breathe through nose instead. This makes sense for me since like our instinct says, we may want to overload the oxygen when we need strength instead of cardio but maybe breathing through nose is more effective on that as well I'm just not used to it.

Would have made more sense to wear a pulse oximeter while running to read the Oxygen percentage.

Honestly I can't handle high altitude which is the reason why I hate riding in airplanes and being in high mountains for a long period Of time, but in my personal opinion the athletic training mask may definitely not replace high altitude training, but it probably can replace low density High duration cardio exercises, which in my opinion is definitely beneficial to a certain extent.

[@astraltegic4724]

Why not make blood work before and after ?

[@mantuhray1]

BLUF, it's not analogous to being at high altitude. It has a training benefit of forcing your diaphragm to work harder. It cannot replicate the expansion of the air molecules at high altitude which would trigger the increased production of red blood cells. Getting less air is not the same as getting air that delivers less on a physiological level. You may see cardiorespiratory improvements with training, but this will have nothing to do with hypoxic effects. It is not a sufficient substitute for altitude training and will not directly impact your VO2 max as quickly or significantly as actual altitude training, if at all.

[@scottwhitten2016]

It is not to replace altitude. It does stress your respiratory muscles by adding resistance. BTW, better if you put your ears in holes.

The oxygen content at altitude is exactly the same as at sea level. 20.9% It's the pressure that is lower at altitude, and therefore the “partial” pressure of the oxygen in the air your breath is lower.

[@Flowmada]

No. It does not. Masks simply increase resistance of breathing. It causes lungs to work harder. High altitude completely changes physiological processes within the body due to atmospheric pressure changes. Differences in pressure result in circulatory changes within the circulatory system and organs/tissues within the body. When someone gets injured, doctors put them in a compression chamber to force more oxygen into tissues and accelerate healing. If a mask worked, they'd just keep a steady flow of O2 flowing through their mask/ventilator. This is just a fitness fad.

is this the same mask you used in the "most calories in an hour" video?

[@markthrelfall3577]

Yep 👍

Answered my question bed I typed it 👍

[@Dems411]

nice

[@emanuelalmanzar3008]

I mean your lungs are working harder to get the oxygen but is there any actual oxygen depletion ?

You needed 12 minutes to say "no they don't"?

[@markthrelfall3577]

Well there was a little more to it than that. But yes, in summary, "no they don't" :) But the debates are interesting, and the idea of RMT. Unless of course you knew all of that already

[@ivannikonov3047]

Well, every time you breathe out, the mask is full of “used” air, so next time you breathe in some of your intake will be this used air, so your oxygen intake levels will probably be lower, plus you will be working out your breathing muscles, as the mask makes it harder. I’m no doctor, but this seems to have positive effects if used correctly. This needs to be researched though. I have this mask, and it definitely makes training harder, but I used it when I was training for anaerobic sports (all in 5 min runs & mma), and was a complete noob in aerobic&cardio departments. When I got into running I realized my cardio is very bad, I got very high pulse at very low paces, My hr goes up very fast, but I can tolerate 90%+ max hr for periods well above average. Now I know that’s neither healthy nor efficient endurance training. It still interesting how 90%+ effort training made running slow harder for me.
