I had a race that went from around 5,000 ft above sea level to 10,300 ft above sea level over the course of 9 miles. I would go to the summit and run down about 1,500 ft of elevation and then run back up. I was in the best shape of my life during that training period. La Luz Trail Race 2019.
Think of it this way. Training is physical stress on your body in a controlled environment. So, if you get used to performing in lower air pressure, doing to the same exercise at the sea level you'll find previously unobtainable stamina.
@@Shootskas Well, yes. Just like with any physical activity/exercise. Only by regular exercise (exposure to high altitudes) you gain the endurance, strength etc.
I live in high altitude and would rather live at sea level. It's not ideal for people with asthma or arthritis among other conditions. You can adapt, but this adaptation doesn't eliminate the issues. It's great if you want to train or have something to brag about when you reach the lower altitudes. I can walk and run farther and lift items for longer periods of time when I'm visiting family or places at lower altitudes
I ran my first marathon last year at 21yrs, I live in the mountains sorrounding Medellín at almost exactly 7000ft and have always worked out at Medellín's altitude. I do consider the coincidental altitude training a pretty substantial contributing factor in achieving the condition that was necessary.
I attended University of Wyoming (7,200ft elevation) back in the olden times. We could definitely out-endure anyone from lower altitudes, especially at sea level.
This channel is so freaking amazing, it got me through my year of A&P and now I keep coming back for more as I specialize in certain subjects. Thank you for everything you guys do 🤘🏽❤
I live at 7300' and almost never go below 4000', but when i go to sea level it's like having an infinite endurance cheat code. I've lived over 5500' for the past 20someodd years until 2020 when i moved higher up the mountain to where i am now.
Solid information. Interesting you refocused on hypoxia rather than acclimatization. This leaves room for hypoxia training such as deep scuba diving and Wim Hof’s breathing techniques. AMS, HACE and HAPE is no joke. Bring an air can and medicine if you’re going to high altitudes. You may save your own or others lives.
I live around 4500 feet and commonly train trails and hiking up to 10k. Recently went on a trip to sea level and felt an infinite boost of energy the first few days, I was able to run further than ever
Fascinating topic! High-altitude training is such a game-changer for athletes and fitness enthusiasts. Excited to learn how it enhances endurance and performance!
Oo yes. This is a good one. Even my sister that’s a doc is not really very educated in high altitude science. Apparently there’s still a lot of research that needs to be done but it’s a tough study to do with a big enough study group size.
I live at 5000-6000 feet but go hiking and skiing at over 10000 feet. I recently went to sea level for my basic freediving certification and ended up doing a 2 min 20 second breath hold on my first try. Currently training to get to that level at altitude so that when I go back for my advanced cert I can do even better!
I grew up in Albuquerque and there were always runners using a local track to train. I also joke that growing up there is why my resting heart rate is in the 50s even though I'm the opposite of athletic. When my parents visited me when we lived in NC they complained the air was too thick, between the humidity and oxygen level.
Bolivian olympic athlete Garibay is using this as his training strategy. he went back to La Paz after the presentation in Paris to train in high altitude until it's time to fly back to France and compite
He actually went back to Oruro which has a higher elevation than La Paz and it has already worked for him, that’s how he broke the Mexico City marathon record. I think he is gonna do great in Paris 2024

Hi there. I like your channel and benefit from your deep dives in my practice as an ICU RN. A lot of the content here about physiological adaptation to hypoxia applies to some of my Pts presenting with hypoxia for other reasons. . . . I do want to just mention that seeing you present your videos with gloves on kinda takes me out. I understand that you have cadavers around, but good practice is to discard gloves often. Even if you’re working on the same Pt (or cadaver), it’s good practice to discard gloves between tasks and perform hand hygiene. Seeing you present most the entire video with gloves on seems like you’re not to practicing good hand hygiene-I assume you actually are doing good hygiene, but because we aren’t seeing you gel or scrub between discarding and applying gloves, it makes it look like you’re wearing the same gloves for long periods of time. . . . Just wanted to mention that. ☺️ . . . Thanks for your awesome videos!
Notably absent from this video is a discussion of how long any measurable effects last upon returning to sea level or some level much lower than 7K+ feet. My understanding is, not very long. Apparently, the human body is extremely efficient when it comes to discarding what it no longer needs. Those extra red blood cells and other adaptations disappear in a very short time, measured in mere days (as opposed to weeks, months, years, etc.), from what I've been able to gather. Wish IHA had included that info here. That omission notwithstanding, they do present some excellent information here.
I don't imagine the extra capilarization gets undone so quickly. That means that even if the red blood cell count decreases over days, one still has additional capillariy perfusion in muscle tissue, delivering more oxygen, more efficiently, to working muscles.
@@RichardHarlos "Imagine" is the part I have a problem with. I'm asking for science to be presented here, not someone's imagination. Imagine (no pun intended) if this video were instead titled "How *I Imagine* Training At Elevation Changes Your Body." Yeah, that wouldn't be good. Also, how is "additional capillary perfusion" an asset if the red blood cell count drops back to normal? If the red blood cell count is normal, the cells can only carry so much oxygen to the capillaries, regardless of an increase in perfusion capacity. The red blood cell count is the limiting factor here. You need an increase in both to get a benefit. And how long does "additional capillary perfusion" last, even if it were key? Again, we need some science here. Speculation doesn't cut it.

What you did is mention that something you're interested in, isn't in the video: _"Notably absent from this video..."_ then you described what you were interested in, and concluded with a _"Wish IHA had included that info here."_ If you wanted answers, you could have asked search engines and AI. So maybe you're not as interested in answers as you are in criticizing? Maybe?
@@RichardHarlos HARLOS: "Red blood cell concentration is independent from plasma volume. Additional capillaries imply increased volume. Within this additional volume are additional red blood cells. Even if the concentration returns to baseline, the additional volume implies additional oxygen transport." If the red blood cell count concentration drops back to baseline, there is no "additional red blood cells" in "this additional (plasma) volume. That's what baseline means. Also, "implies?" Really? Very scientific word, that. It belongs with "I imagine" in the Pure Speculation bin. HARLOS: "blue: "And how long does "additional capillary perfusion" last, even if it were key?" Well, it is key, and I don't know how long it lasts." Yes, thank you, it IS key and that was, in essence, my original referenced topic. Since you don't know, your "I imagine" isn't helpful, which was part of my second comment. You "imagine" and you "don't know;" so why respond to a non-question with a speculative answer? Again, if I had said "can anyone tell me..." then fine, knock yourself out with science-based answers. I said "notably absent" and "wish they had included..." because I felt that info would improve the video. That should be exceptionally clear from my comment if you understand the English language. Maybe you have reading comprehension issues? Maybe? I see from the rest of your comment that I struck a nerve... HARLOS: "You're shuffling things around after the fact. You didn't ask for scientific replies. You didn't ask for replies at all. What you did is mention that something you're interested in, isn't in the video: "Notably absent from this video..." then you described what you were interested in, and concluded with a "Wish IHA had included that info here." Yes, exactly, very good. So why are you providing information to someone who is clearly not asking for it? Notice the wording: "wish IHA had included that info here." I wasn't asking you for the info; I was suggesting IHA was remiss for not including it. That's what is known as a "constructive criticism," something maybe you don't deal with well. Maybe? HARLO: "If you wanted answers, you could have asked search engines and AI. So maybe you're not as interested in answers as you are in criticizing? Maybe?" First, if you know I could look up that info, then why did you feel compelled to offer it in a response to my comment? WHOOPS! Again, I never said I wanted any answers. Again, I simply noted that certain info was missing from the video, which you seized on to post the product of your imagination; maybe because you have a fragile ego and wanted to sound intelligent? Maybe? Moving on now, because based on both your replies, it's clear to me your sense of self worth derives in large part from attention from others, and I don't care to feed into that.
@@blueeyeddevil1 Remember when I mentioned to you at the end of my 2nd reply that *"If you wanted answers, you could have asked search engines and AI. So maybe you're not as interested in answers as you are in criticizing? Maybe?"* Did you do that? Apparently not. If you had, you would have the answers that you claimed to be interested in. So, as I suspected, you're more motivated to contend than you are to seek understanding. I have zero interest in feeding such trolling so I did you a favor and asked Claude AI 3.5 the following question: _When someone who spends most of their time at sea level ascends to altitude (let's say 7,000 feet above sea level), they go through a period of acclimatization to the higher elevation. During this acclimatization, they experience several accommodations to their biology including an increase in plasma volume, an increase in red blood cell count, and an increase in capillaries to facilitate sufficient oxygen transport throughout the body. Assuming they remain at altitude long enough for these accommodations to meet the body's oxygen requirements, I'm curious to know whether, upon returning to, and staying at, sea level... do these adaptations revert back to the state prior to ascending to higher altitude? If so, how long does it take for each adaptation to return to its pre-altitude baseline?_ Here is Claude's answer. And with that, I'll bid you farewell: This is an excellent question about the physiological adaptations to altitude and their reversibility. Let's break down the response into two parts: first, addressing whether these adaptations revert upon returning to sea level, and second, discussing the timeline for this reversion. **Do altitude adaptations revert upon returning to sea level?** Yes, the physiological adaptations that occur during acclimatization to high altitude do generally revert when an individual returns to sea level. This process is known as de-acclimatization. The body's adaptations are a response to the lower partial pressure of oxygen at higher altitudes, and when this stimulus is removed (by returning to sea level), the body gradually returns to its pre-altitude state. **Timeline for reverting to pre-altitude baseline:** The timeline for de-acclimatization varies depending on the specific adaptation and individual factors. Here's a breakdown of the main adaptations you mentioned: a) Increase in plasma volume: This is one of the quickest adaptations to revert. The increased plasma volume typically returns to baseline within a few days to a week after returning to sea level. b) Increase in red blood cell count (polycythemia): The reversal of increased red blood cell production takes longer. The lifespan of a red blood cell is about 120 days, so the complete normalization of red blood cell count can take several weeks to a few months. However, significant changes are often observable within 2-3 weeks. c) Increase in capillaries: The increase in capillary density (angiogenesis) is one of the slower adaptations to reverse. While the exact timeline can vary, it generally takes several weeks to months for capillary density to return to sea-level normal. Other adaptations not mentioned in your question but worth noting: d) Ventilatory adaptations: Changes in breathing patterns and sensitivity to CO2 typically revert within a few days to a week. e) Hemoglobin affinity for oxygen: The decreased affinity of hemoglobin for oxygen (to facilitate oxygen release to tissues) usually normalizes within a few days. It's important to note that the exact timeline can vary based on several factors: *Duration of stay at altitude:* Longer stays may lead to more profound adaptations that take longer to reverse. *Individual variability:* Some people may de-acclimatize faster or slower than others. *Level of physical activity:* Maintaining high levels of physical activity at sea level may slow the de-acclimatization process for some adaptations. *Age and overall health:* These factors can influence how quickly the body readjusts. In conclusion, while the body does revert to its pre-altitude state upon returning to sea level, the process occurs at different rates for different physiological systems. Some changes reverse within days, while others may take weeks to months to fully normalize. Would you like me to elaborate on any specific aspect of altitude acclimatization or de-acclimatization?
Please discuss longevity and altitude. It has been my understanding that people living many years above something like 7000 feet have poorer longevity, on average.
Clean air is the key. In our days theres no low altitude with clean air. Usually places at 2000-4000 ft have clean air and will help boost training and red blood cells number..
Big Bear is where American pro boxers train for a fight.Many greats trained there.The greatest fighters ever. Workout at high altitudes.Mexican fighters train at big levels in Mexico.
Awesome video. Could you do something based on the same topic. Is South Africa, doctors treating kids with asthma advice parent to move away from coast to JHB thats about 5500 ft in elevation. So the question is why does living at a higher elevation help kids with asthma?
If it were purely based on altitude then Tibetans and Nepalese would be by far the best, but the reason why East Africans are so dominant is because of the high temperature of equatorial Africa. Generations of living in high temperatures means their bodies have adapted the best cooling mechanisms in the world. West African genes make the best sprinters because they have hot temperatures, the same goes for South Asians but you see less of them in the Olympics due to worse infrastructure for producing world class athletes. East Africa produces the best long distance runners because of the high temperatures but also the high altitude of the East African plateau means they have naturally better endurance than other equatorial ethnicities
I live at an altitude of 3,166’ I cannot help but find it humorous that people have difficulty breathing at this elevation (I live in a popular tourist destination so many people from lower altitudes visit my area)
lori wrote, _"I cannot help but find it humorous that people have difficulty breathing at this elevation"_ Finding people's wellness struggles 'humorous' places you on the sadism spectrum.
I always wondered if you could make low pressure barometric training facilities to get this effect. I wonder what percentage of time you have to endure to get the effects. I went higher altitude from sea level for a few days. Never felt weaker in my life.
I live at 6,000' in Colorado Springs. Moved here from Ohio in 2013, definitely took about a year to get used to it. Now it's no big deal unless I go over 13k feet. Mountain biked up Pikes Peak twice on Barr trail. That will test you!
consider if you will, a sealed container, like a submarine. we run our submarines with normal atmospheric pressure typically at sea level. but as we breathe, we consume oxygen and waste carbon dioxide. we do scrub the co2 from the air and discharge it out, and we do have oxygen tanks on board to replace the o2. but our typical o2 concentration on board runs as low as 17% for 2 reasons, ok just one main reason. fire. lower o2 levels inhibit fire propagation. the lowest i have seen the o2 concentration on ship was 16%.
Where is the limit? Can I move into a sealed chamber and slowly lower the air pressure to total vacuum? Maybe I can do space walks without a space suit!
What about live low, train high? I think I'll be a bit better cause you recover and sleep at low elevation with lots of oxygen pressure. I live in San bernardino (45min to big bear, at 500ft elvation)
Could a similar effect be achieved by holding your breath at a low altitude, or just breathing less? Would this be bad because of the higher partial pressure of CO2?
So, to maximise the amount of production of red blood cells, should one: (1) also consume iron-rich foods to assist in the production of red blood cells, or (2) totally avoid such foods to allow the body to naturally produce as much red blood cells as necessary? Appreciate your views.

You're shuffling things around after the fact. You didn't ask for scientific replies. You didn't ask for replies at all. What you did is mention that something you're interested in, isn't in the video:
_"Notably absent from this video..."_ then you described what you were interested in, and concluded with a _"Wish IHA had included that info here."_
If you wanted answers, you could have asked search engines and AI. So maybe you're not as interested in answers as you are in criticizing? Maybe?

HARLOS: "Red blood cell concentration is independent from plasma volume. Additional capillaries imply increased volume. Within this additional volume are additional red blood cells.
Even if the concentration returns to baseline, the additional volume implies additional oxygen transport."
If the red blood cell count concentration drops back to baseline, there is no "additional red blood cells" in "this additional (plasma) volume. That's what baseline means. Also, "implies?" Really? Very scientific word, that. It belongs with "I imagine" in the Pure Speculation bin.
HARLOS: "blue: "And how long does "additional capillary perfusion" last, even if it were key?"
Well, it is key, and I don't know how long it lasts."
Yes, thank you, it IS key and that was, in essence, my original referenced topic. Since you don't know, your "I imagine" isn't helpful, which was part of my second comment. You "imagine" and you "don't know;" so why respond to a non-question with a speculative answer? Again, if I had said "can anyone tell me..." then fine, knock yourself out with science-based answers. I said "notably absent" and "wish they had included..." because I felt that info would improve the video. That should be exceptionally clear from my comment if you understand the English language. Maybe you have reading comprehension issues? Maybe?
I see from the rest of your comment that I struck a nerve...

Yes, exactly, very good. So why are you providing information to someone who is clearly not asking for it? Notice the wording: "wish IHA had included that info here." I wasn't asking you for the info; I was suggesting IHA was remiss for not including it. That's what is known as a "constructive criticism," something maybe you don't deal with well. Maybe?
HARLO: "If you wanted answers, you could have asked search engines and AI. So maybe you're not as interested in answers as you are in criticizing? Maybe?"
First, if you know I could look up that info, then why did you feel compelled to offer it in a response to my comment? WHOOPS!
Again, I never said I wanted any answers. Again, I simply noted that certain info was missing from the video, which you seized on to post the product of your imagination; maybe because you have a fragile ego and wanted to sound intelligent? Maybe?
Moving on now, because based on both your replies, it's clear to me your sense of self worth derives in large part from attention from others, and I don't care to feed into that.
@@blueeyeddevil1 Remember when I mentioned to you at the end of my 2nd reply that *"If you wanted answers, you could have asked search engines and AI. So maybe you're not as interested in answers as you are in criticizing? Maybe?"* Did you do that? Apparently not. If you had, you would have the answers that you claimed to be interested in. So, as I suspected, you're more motivated to contend than you are to seek understanding. I have zero interest in feeding such trolling so I did you a favor and asked Claude AI 3.5 the following question:
_When someone who spends most of their time at sea level ascends to altitude (let's say 7,000 feet above sea level), they go through a period of acclimatization to the higher elevation. During this acclimatization, they experience several accommodations to their biology including an increase in plasma volume, an increase in red blood cell count, and an increase in capillaries to facilitate sufficient oxygen transport throughout the body. Assuming they remain at altitude long enough for these accommodations to meet the body's oxygen requirements, I'm curious to know whether, upon returning to, and staying at, sea level... do these adaptations revert back to the state prior to ascending to higher altitude? If so, how long does it take for each adaptation to return to its pre-altitude baseline?_
Here is Claude's answer. And with that, I'll bid you farewell:
This is an excellent question about the physiological adaptations to altitude and their reversibility. Let's break down the response into two parts: first, addressing whether these adaptations revert upon returning to sea level, and second, discussing the timeline for this reversion.
**Do altitude adaptations revert upon returning to sea level?**
Yes, the physiological adaptations that occur during acclimatization to high altitude do generally revert when an individual returns to sea level. This process is known as de-acclimatization. The body's adaptations are a response to the lower partial pressure of oxygen at higher altitudes, and when this stimulus is removed (by returning to sea level), the body gradually returns to its pre-altitude state.
**Timeline for reverting to pre-altitude baseline:**
The timeline for de-acclimatization varies depending on the specific adaptation and individual factors. Here's a breakdown of the main adaptations you mentioned:
a) Increase in plasma volume:
This is one of the quickest adaptations to revert. The increased plasma volume typically returns to baseline within a few days to a week after returning to sea level.
b) Increase in red blood cell count (polycythemia):
The reversal of increased red blood cell production takes longer. The lifespan of a red blood cell is about 120 days, so the complete normalization of red blood cell count can take several weeks to a few months. However, significant changes are often observable within 2-3 weeks.
c) Increase in capillaries:
The increase in capillary density (angiogenesis) is one of the slower adaptations to reverse. While the exact timeline can vary, it generally takes several weeks to months for capillary density to return to sea-level normal.
Other adaptations not mentioned in your question but worth noting:
d) Ventilatory adaptations:
Changes in breathing patterns and sensitivity to CO2 typically revert within a few days to a week.
e) Hemoglobin affinity for oxygen:
The decreased affinity of hemoglobin for oxygen (to facilitate oxygen release to tissues) usually normalizes within a few days.
It's important to note that the exact timeline can vary based on several factors:
*Duration of stay at altitude:* Longer stays may lead to more profound adaptations that take longer to reverse.
*Individual variability:* Some people may de-acclimatize faster or slower than others.
*Level of physical activity:* Maintaining high levels of physical activity at sea level may slow the de-acclimatization process for some adaptations.
*Age and overall health:* These factors can influence how quickly the body readjusts.
In conclusion, while the body does revert to its pre-altitude state upon returning to sea level, the process occurs at different rates for different physiological systems. Some changes reverse within days, while others may take weeks to months to fully normalize. Would you like me to elaborate on any specific aspect of altitude acclimatization or de-acclimatization?
Do one about the harmfull effects of antipsychotics
Please discuss longevity and altitude. It has been my understanding that people living many years above something like 7000 feet have poorer longevity, on average.
Clean air is the key. In our days theres no low altitude with clean air.
Usually places at 2000-4000 ft have clean air and will help boost training and red blood cells number..
What do you think of a a device the put artificial pressure on feet and chest to pump blood for you
The creativity tho 😙
Big Bear is where American pro boxers train for a fight.Many greats trained there.The greatest fighters ever. Workout at high altitudes.Mexican fighters train at big levels in Mexico.
What alternatives would there be to altitude training? Swimming?
Awesome video. Could you do something based on the same topic. Is South Africa, doctors treating kids with asthma advice parent to move away from coast to JHB thats about 5500 ft in elevation. So the question is why does living at a higher elevation help kids with asthma?
Nice to know it works!
I saw lizard lizard on the heart in the thumbnail and now i can't unsee it
Myself
My 16 year old son
My 14 year old daughter all of us get altitude training at almost 49% of the schedule month
#Triathlete ✌️🤘👍
I was just reading how Kenyans and other eastern Africans run better than most of the world before this dropped 😂
If it were purely based on altitude then Tibetans and Nepalese would be by far the best, but the reason why East Africans are so dominant is because of the high temperature of equatorial Africa. Generations of living in high temperatures means their bodies have adapted the best cooling mechanisms in the world. West African genes make the best sprinters because they have hot temperatures, the same goes for South Asians but you see less of them in the Olympics due to worse infrastructure for producing world class athletes. East Africa produces the best long distance runners because of the high temperatures but also the high altitude of the East African plateau means they have naturally better endurance than other equatorial ethnicities
Nice 👍
Hi could you please start taking detailed anatomy classes?
I live in the highlands, yeppie, this is true

Can you do a close up of muscle adhesions
I live at an altitude of 3,166’ I cannot help but find it humorous that people have difficulty breathing at this elevation (I live in a popular tourist destination so many people from lower altitudes visit my area)

Finding people's wellness struggles 'humorous' places you on the sadism spectrum.
What about a video for emphysema?
I always wondered if you could make low pressure barometric training facilities to get this effect. I wonder what percentage of time you have to endure to get the effects. I went higher altitude from sea level for a few days. Never felt weaker in my life.
Is there anything one can do to get the same results without having to move to a high altitude environment..eg; masks, supplements, chambers..thanks
I live at 6,000' in Colorado Springs. Moved here from Ohio in 2013, definitely took about a year to get used to it. Now it's no big deal unless I go over 13k feet.
Mountain biked up Pikes Peak twice on Barr trail. That will test you!
That does sound like quite the test!
@@theanatomylabNot so much on the downhill!
consider if you will, a sealed container, like a submarine. we run our submarines with normal atmospheric pressure typically at sea level. but as we breathe, we consume oxygen and waste carbon dioxide. we do scrub the co2 from the air and discharge it out, and we do have oxygen tanks on board to replace the o2. but our typical o2 concentration on board runs as low as 17% for 2 reasons, ok just one main reason. fire. lower o2 levels inhibit fire propagation. the lowest i have seen the o2 concentration on ship was 16%.
And here I am living at sea level for almost all my eternity so far.
I'd like to see a compare and contrast with CO2 rebreathers, which seem to be all the rage in cycling.
Science Research Backed Studies on Athletes that were wearing a bin bag liner on a run/Training acts exactly the same as High Altitude Training.
How long elevation adaption last when coming back to sea level?
Where is the limit? Can I move into a sealed chamber and slowly lower the air pressure to total vacuum? Maybe I can do space walks without a space suit!
Why don't the blood vessel walls themselves uses up the oxygen .
What about live low, train high?
I think I'll be a bit better cause you recover and sleep at low elevation with lots of oxygen pressure.
I live in San bernardino (45min to big bear, at 500ft elvation)
What about using a High altitude breather?
Watching from Florida (where the highest point is 300 feet above sea level): "Interesting..."
This guy has to be LDS.
Why does the insulin resistance reduse on high altitudes?- i always wonder
Could a similar effect be achieved by holding your breath at a low altitude, or just breathing less? Would this be bad because of the higher partial pressure of CO2?
So, to maximise the amount of production of red blood cells, should one:
(1) also consume iron-rich foods to assist in the production of red blood cells, or
(2) totally avoid such foods to allow the body to naturally produce as much red blood cells as necessary?
Appreciate your views.
Hey. What happened to the other guy that does the videos sometimes?
how is this compared to one of those mask you see on the internet? the mask one can use to simulate the hypoxia while at sea level.
So the atmosphere ends at a fine line afterall
so I was born in Little Rock Arkansas but grew up in Spokane Washinton so about 1600 feet difference, so what would be the effect
I got too high one time but that was something different.
What if its easier for me too breathe and run at 9000 feet in colorado vs groundlevel in texas
