      WELCOME TO THE CASCADECLIMBERS.COM FORUMS   02/03/18

      We have upgraded to new forum software as of late last year, and it makes everything here so much better!  It is now much easier to do pretty much anything, including write Trip Reports, sell gear, schedule climbing related events, and more. There is a new reputation system that allows for positive contributors to be recognized,  it is possible to tag content with identifiers, drag and drop in images, and it is much easier to embed multimedia content from Youtube, Vimeo, and more.  In all, the site is much more user friendly, bug free, and feature rich!   Whether you're a new user or a grizzled cascadeclimbers.com veteran, we think you'll love the new forums. Enjoy!

Breathing?

Recommended Posts

May seem like a dumb question, but what's the best way to breathe during high output exercise? Long full breaths, deep quick breaths, in through the mouth and out through the nose? I'm thinking there's some science behind it, namely the most efficiecnt way to exchange CO2 for O2, and I find that forcing myself to consciously breathe rather than breathe autonomicaly has improved benefits, but what works the best, as far as the exercise physiologists are concerned?

I like to do belly breathing as much as possible to keep the side stitches at bay(or to get rid of one). If I stop paying attention to my breathing it gets weak and shallow and my performance follows.

 

If I'm cranking full-steam up a hill, I do an exaggerated, forceful exhalation every third or fourth breath to fully clear out the carbon dioxide and maximize the oxygen I can take in on the next inhalation(disclaimer: I don't know the true physiological merits of this technique, but I do find that it helps tremendously).

 

Massaging your diaphragm trigger points and intercostals can facilitate the ability to take those deep, relaxed breaths.

i gave up breathing a couple years ago.

i've found that being a zombie has done wonders for my stamina and pain tolerance.

I can't speak much to whether there is data about one particular breathing technique being better than another but there is not much physiologic merit to the idea of doing one thing or another to fully clear out the carbon dioxide or maximize the oxygen you take in. If you have healthy lungs, they will do an efficient job of eliminating carbon dioxide and taking in oxygen independent of whether or not you pressure breathe, do a forced exhalation every 4th breath or do other things.

 

In the end, with healthy people (i.e. no emphysema, pulmonary hypertension, severe asthma, heart failure) maximum exercise capacity is limited by the ability of the heart to deliver oxygen to the exercising muscles. Healthy people are not limited by the ability to take oxygen in or get rid of carbon dioxide through the lungs so the exact pattern of breathing will not have much of an impact.
