Apples for better lung function?(7 posts)

Apples for better lung function?GD

Explain to me the scientific reasoning for a recent one-paragraph blurb in a bike mag about apples improving your breathing/respiration/lung function/etc.... sounds a little odd to me....

I remember hearing about Tibetan monks who would use this method to increase their oxygen intake at high altitude during extended retreats. Apparently they'd swallow an apple whole which would stretch their larynx up to 40% wider than normal.

I would expect the opposite effect...Humma Hah

... swallowing an apple might stretch the esophagus but I would expect it to crush the adjacent trachea.

A while ago, Doug Sloan posted something about the use of sodium phosphate for performance enhancement. It evidently worked by shifting the oxygen uptake curve of hemoglobin, evidently shifting human blood to work more like bird blood. I predicted that, at some altitude, this effect might backfire, causing an inability to take up oxegen when the partial pressure was below some critical level. Since then I've heard from folks who've used it up to 11,000 ft, so its not likely much trouble on US roads.

Anyway, the effect may be partly due to blood pH buffering, making the blood more basic, and perhaps combating lactic acid. Possibly the acid in apples make the blood slighty more acidic, shifting the curve the other way. That might reduce overall oxygen uptake at sea level, but help humans scavenge oxygen more effectively at extreme altitudes. It is said that high blood acidity (low pH) is apt to trigger exercise-induced asthma in folks prone to that problem. I personally seem to do better when I avoid acid foods before riding.

has sodium bicarbonate in it...my dad (doctor)has the theory that the bicarbonate (i think it was that part) counteracts acid in the blood stream...thats all i know..what do you know
Sounds about right ...Humma Hah

... some folks take a little baking soda (sodium bicarbonate) before riding, and my sports drink, ERG, has some carbonates in it. I've also tried Tums (calcium carbonate) which may help a little.

Seltzer water has water and carbon dioxide. That's all.
