freedivers should be the first ones to know about the Bohr effect!

good to hear! 🙏

oh God hahaha 😁

that might be a good idea yes.. short answer : it increases po2 (partial pressure of oxygen).

yes, we all have 95-99% under normal circumstances. Situations where spo2 can be lower: when you have some kind of pulmonary disease, or when you're at high altitude.

Glad it was helpful!

thanks 🙏

theoretically better would be to use the nose with a nose snorkel, but for practical reasons we use a mouth snorkel. as far as I know nobody has invented a nose snorkel yet.

buteyko, or Oxygen Advantage, or just simply DON'T HYPERVENTILATE. Not everything we do needs a name of a doctor or a book 😁

No! there is no "hyper-oxygenation". You are right on the lowering of the Co2, but very wrong on the increase of "oxygenation". This is exactly what I explain in this video!

The “hyper oxygenation” is just a term implying the increased ratio of O2 to CO2. Because if CO2 decreased and O2 stayed the same, then the ratio is different. “Oxygenation” it’s just a layman’s term for this ratio disparity.

@@user-rp8yc9qn3m it seems people have their own opinions on how to fill in the definition of "oxygenation". That alone is already a problem. We should simply stop using that word.

@@gertleroy Fair enough! 😂

thanks man. Was this something new for you, or did you know already about the Bohr-Effect ? I'm curious to know..

you mean 20 secs not minutes right? it's OK to take 1 or 2 bigger breaths right before taking the big final breath. no worries!

@@gertleroy yes you are right "seconds" what I wanted to say 😊. Thanks for the clarification you are awesome 💚💐

lung capacity: thoracic stretching and cardio. James Nestor's book should be seen as a collection or anecdotal evidence and data taken out of context. Not as a scientific work.

Thanks for that. Where can I find examples of the thoracic stretching?

​@@gertleroythanks.

on empty lungs hypoxia comes first. it's a hypoxic breathhold. On full lungs, hypercapnia comes first. It's a hypercapnic breathhold. now that being said, in empty lungs (which are never empty) you also have Co2 building up, and quite fast becauze your breathhold is so short.

I don't think this video is about vasoconstriction only. it's mainly about the Bohr effect which describes the relation between Co2 and how oxygen is delivered to the working muscles.

if you are at high altitude or if you're having a respiratory illness that keeps your spo2 lower than 95%, then hyperventilation can bring that up to normal ranges again 95-99% For all other people who have normal spo2 ranges hyperventilation will not make a difference. I explain in this video that a temporary increase from let's say 97% to 99% is negligible.

💥🙏🙏🙏

I don't think this video even mentions the name wim hof once.. (correct me if I'm wrong). But now that you do mention him.. hyperventilation does not create Co2 tolerance. It does the opposite. And if hyperventilation wouldnindeed create more red blood cells, ALL freedivers woukd be on it (for dry practice) and guess what, they're not. It is very difficult to increase long term red blood count through natural ways. Freedivers are literally devoting their lives to studying how to increase the red blood count, and high altitude training might temporarily increase RBC, but not long lasting. What does increase RBC is certain supplemts or "doping" like testosterone or EPO. The WHM does NOT increase RBC.

⁠​⁠@@gertleroy- you clearly don’t understand man … sorry … try to talk about breathing outside of the free diving community 😉 - 1) Your video is in the Wim Hof playlist … 2) read before you answer … I didn’t say hyperventilation creates more red blood cells - I said hypoxia in the retention phase does. 2) During WHM breathing (because of low CO2 levels, people go into intermittent hypoxia … You clearly don’t know the physiological consequences of Hypoxia … yes, release of EPO is one of them … More red blood cells is better oxygenation of the cells. 3) You write “more red blood cells but not for a long time” … Red blood cells have a life span of 120 days 😉 (fact) 4) in another video, you explain that the tingling is a consequence of CO2 levels being low and because of the Bohr effect, right. which is true. In most people who practice the WHM breathing, the tingling disappears over time, while the CO2 levels are as low as before … This means : CO2 tolerance has increased … On another spectrum as CO2 tolerance training after breath holding. - Try to come out of your box 😉 - Once again- you are an expert in CO2 levels, Bohr effect, but the rest, you need to dig a little deeper. very good with breathing related to freediving … But a lot of other videos, you clearly lack deeper knowledge and you come to a lot of wrong conclusions and wrong advice … - All the best 😉 - I’m done watching your videos on WHM (playlist) / you clearly don’t know - and people who point this out are from a cult or are emotionally reactive 😅 - the fact that you yourself may be wrong on physiology because you only talk about CO2 levels, Bohr effect and only stick to that seems to be impossible, cause you studied CO2 levels and the Bohr effe t (which is common knowledge btw) - Waist of time and bad advice for your viewers … Plain and simple …

@@dominiquestulens if hypoxia is what you're going for (and i doubt you should unless there are very specific reasons for this) then there are other ways to go into hypoxia. You dont need to hyperventilate (heavily) to experience hypoxia on a breathhold. You could (of hypoxia woukd be your goal) engage in typical hypoxia training loke freedivers do (multiple submaximal breathholds, or exhale brearhholds (FRC like the WHM, or RV = residual vomume) but WITHOUT the prior hyperventilation. the wim hof breathhold is a hypoxic breathhold (if at least the hyperventilation was heavy enough) meaning low O2 comes before high Co2 thus the lack of bodily warning signs to abort the breathhold and thus the many blackouts on the WHM. That's why it comes with a disclaimer. ps. in freediving hypoxia training is for the advanced athletes who have built up enough Co2 tolerance alrwady over the years. the other 99% of the world population dienst need hypoxia training. they woukd be far better if wirh Co2 tolerance training, hence the many breath coaches in topsport teaching athletes now to hold the breath WITHOUT prior hyperventilation.

⁠@@gertleroy- Haha, man, exactly what I mean. You have some serious blind spots. Rest of the world doesn’t need hypoxia training … - Just stick with the freediving. That very small percentage of people that freedive have something on your freedive video’s - “The rest of the people doesn’t need hypoxiatraining” 🤣 … This clearly proves you don’t know the advantages of hypoxiatraining … -> This is embarrassing for somebody who claims to know a lot … With every answer you give, you spread more desinformation and you don’t seem to be aware. - Waist of my time, waist of many peoples time … only they don’t know
