Professional surfer Laird Hamilton says Vo2 max can be increased by breathing through your nose

You #1 in USA. Beautiful Russian woman rewards will be yours. Give yourself thanks.

J - Are you saying VO2 Max could not be elevated by breathing through your nose?

On the podcast, he argues that: 1) Humans use oxygen more readily / efficiently when we breathe in through the nose. 2) If a person is a full time mouth breather, the nasal airway may shrink... decreasing the ability to get the benefits from point #1. 3) The problems associated with mouth breathing are reversible.

He indirectly addressed aerobic abilities being hampered by being a habitual mouth breather.

Why is it then that the consensus here has always been that sinusitis doesn't affect running (other than indirectly through poor sleep and such)?

I've read here many times that runners at any distance get sufficient oxygen through their mouths. This has always struck me as silly. I wonder if Cheptegai would have broken the WR the other day with plugs blocking each nostril?

The British runner Jamie Reekie made a massive jump in performance last year only weeks after having sinus surgery.

I think Jamin could be on to something here.

Just rubbish!

Laird is an enormous tool and is all about himself. He is contribution to fitnesses is lifting weights under water. Inelegant, ugly power surfing style too.

from the interview: well first of all you were designed to breed your sinuses and your nose were designed for breathing and so you actually admit a gas in your sinuses from my understanding gas called nitric oxide which is a vasodilator it helps you absorb oxygen so by breathing through your nose plus you reduce the amount of intake that you have and that gets you CO2 tolerance.

I think that's logically

I posted like two days ago that Novak Djokovic (tennis) also had nasal surgery to "improve his airflow" a couple years before he became number one in the world.

Nasal surgery seems to be a stealth way to give you an edge.

A friend has encouraged me to read a book "Breathe" that promotes breathing through the nose. I think that is good advice as the nose filters air far better. However, at some level of exercise you cannot get enough air in through just the nares.

I have not read the book, but I first take is that it likely takes a few nuggets that are true and extrapolates when it should not.

I'm actually in the process of trying to do all my easy runs and warmup jogs while breathing through my nose. The main thing benefit I'm feeling is the ability to actually control my breathing. You can relate this idea to how swimmers have to control their breathe for obvious reasons. Even when racing there is a pace to it.

9 times out of 10 you are probably breathing too much for what your body can actually absorb/convert in the lungs when you let your breathing get out of control as effort goes up. This is wasted energy. Breathing through your nose can help you take control of your breathe, or at least that's how I feel so far.

I only breathe through my ears on easy runs

Well that settles it, (channeling Jack Nicholson) "Laird Hamilton sez so...."

Didn’t Josh MacDougal endorse nose breathing?

nose breathing increases PEEP (positive end expiratory pressure) by allowing air to escape through comparatively smaller nasal nare diameter relative to the mouth. You also lose less water through insensible water loss that occurs when running with your mouth agape. People have trouble running while nose breathing at first, because they feel they aren't getting enough oxygen. You are- you just aren't accustomed to the feeling. You also warm and humidify air when inspiring through the nose.

that is all.

This is old news, but it's accurate. In 2000, IIRC, John Douillard wrote Body Mind Sport, which covered nose breathing. I assume the later books include more science, but understand, "nose" breathing isn't taping over your mouth and breathing exclusively through the nose. That might be possible in some sports for some people, but for running, I've been doing it for almost 20 years and I can only do it at a jogging pace. But then, I have the same nose damage that Rogan mentions.

It's also misleading to say "nose breathing" without explaining how the chest and abs affect breathing.

Most mouth breathers breathe with their chests. They breath in, their chest rises as they suck air into their lungs. This isn't efficient or how to nose breath. Instead, you should be belly breathing, also called diaphragm breathing. Ironically, diaphragm breathing is also a misnomer.

Proper breathing is forcefully contracting the abs to force air out of the lungs (mostly through the nose) and then allowing air to flow back in naturally as the abs relax.

Chest breathing is shallow and doesn't bring in as much oxygen as belly breathing.

you're dumb. Try breathing without your diaphragm. impossible.

Good surfer but I don't know about some of his ideas.

..try it for 9 months, maybe you’ll have a major break through.
