Oxygen for sale...
Are you kidding me? I just saw an ad for "pure oxygen" 95% oxygen, the "legal, safe performance enhancer." Anyone try this? Could this be bad for you? I mean other than you spending money on some worthless crap?
Ive had to use it for other reasons than performance; so I don't have the experience really. That being said - I don't think that it would help. The amount that you would need to carry with you just isn't practical.
Yeah this tiny little tube doesn't seem convincing to me...it's about 6 inches tall. The video is pretty funny - they show some goofballs inhaling it and working out - but I'm not posting it because advertising this stuff would be just plane silly.
I remember seeing pix of the pro's taking oxygen before stages of the Red Zinger / Coors Classic.
I went googling and couldn't find on but I did find this pic of Connie Carpenter. Mmmmm.
/ feeling a bit light headed... need some oxygen...

A friend of mine who dived said it was a real pick-me-up if he was feeling groggy. I can't remember how the system worked, exactly, but the way dive tanks are set up, he could take a hit of straight oxygen during the drive home. Not safe or practical long-term. But if they're selling it in little, tiny tanks that can't prevent a person from still breathing a fairly normal mix of air most of the time, it would take some pretty ridiculous extra effort to come up with something dangerous.
I bet it could help recovery to have a slightly oxygen-enriched environment. Again, it would take a lot more than having one of those little tiny tanks.
I'll allow it

Up to ~ 1000 feet above sea level, oxygen saturation on hemoglobin is 98.5% for 'normal' healthy people.
Adding more oxygen barely touches the oxygen dissociation curve.
Read about it: Oxygen
It will make a difference at altitude (high) and for COPD patients.......

I bet they could have sold truckloads of this at the Tour of Beijing or at the Olympics to the riders. Otherwise, not so much...
I couldn't reconcile that with the fact that studies do show you increase work rate if breathing hyperoxic air. I think it must come down to the fact that some oxygen is carried dissolved in the blood rather than bound to hemoglobin and breathing the hyperoxic air increasing that dissolved concentration enough to make a difference.*

*IIRC, the studies that show increased work rate breathing hyperoxic air typically have the subjects exercising at a fairly high intensity, where even a normal healthy person is not going to clinically desaturate their hemoglobin, but might there be a small drop in hemoglobin saturation (say a percent or two) that is avoided by breathing the hyperoxic air? After all, there are certain situations where healthy folks can desaturate even though it is unusual (i.e. some elite athletes doing an all-out effort for a minute or so).

I can't see any benefit of a small container of air. In CO, its not uncommon to find racers that train on Oxygen. Here in Boulder, there are several places you can go to train on Oxygen. Most riders use it for High intensity workouts and you suck down a lot of it, like 100's of pound per workout. At altitude the weak point in a workout is oxygen delivery so the muscles never get fully taxed. The use of Oxygen helps tax the muscles that other wish never get pushed to there limits at altitude. I don't think there are any benefits for people in lower altitudes and for people in high altitudes the benefit is mostly seen when competing in lower altitudes.
I did some of the first work with hyperoxic training when I worked for project '96 (see morris et al. (2010) The effects of breathing supplemental oxygen during altitude training on cycling performance. Journal of Science and Medicine in Sport 3(2) 165-175.) and some follow up work a few years later with Randy Wilber at the USOC lab. The original training study showed that after 3 weeks of living at 6000 ft and training on hyperoxic gas, subjects showed greater improvements in performance when compared to those who were training on normoxic air.
Chris Perry did some work with hyperoxia at sea level and found that it increased work tolerance during high-intensity intervals but didn't look at the training effect. I'm not aware of anyone who has looked at the effects of training while using supplemental O2 at sea leavel. Blood is almost 100% saturated with oxygen at sea level in resting individuals, but I have seen saturations drop to ~90% during heavy exercise when breathing normal air.
As some of you pointed out, breathing supplemental O2 during competition is not practical - you just can't take enough of it with you and the added weight of the apparatus would more than negate the advantage of using the O2.
You can pick up O2 cyclinders from any gas supply house without a prescription. Welders use the stuff all the time.
as a diver, I have multiple cylinders of pure O2 in my inventory.
never tried it before riding, but combined with a Bloody Mary, it's a great hangover remedy.
Yeah, when I make sojourns to altitude, I always feel better after a night of drinking tequila. I don't know why, and I'm not complaining.
funny, back in my younger, wilder days, if i was a bit hungover i would go out the the shop and crack the valve on the O2 bottle, bleed the line and stick the torch in my face to get some relief....

Oxygen delivery is defined as such:
Originally Posted by Dwayne Barry
DO2 = CO X CaO2
CO = cardiac output; CaO2 = oxygen content of blood
CaO2 = [Hgb(1.38)(10)(SaO2)] + [(PaO2)(0.0031)]
Hgb = hemoglobin; SaO2 = oxygen saturation; PaO2 = arterial oxygen pressure or dissolved oxygen in the blood
0.0031 times anything is a small number
Clinically, we think of oxygen delivery as DO2 = CO X [(Hgb)(1.38)(10)(SaO2)]
Thus, I'm not sure how much dissolved oxygen could improve oxygen delivery.
I'd be curious to know the adverse effects of hyperoxic training on the lungs from Dwayne Barry. In critically ill patients there are data suggesting that higher fractions of inspired oxygen can cause damage to the lungs epithelial lining.

Okay, first off if you want to do this, DO NOT use industrial Oxygen. I work for a gas supplier and we carry both industrial and medical oxygen. For breathing you need Medical Oxygen, which is produced under strict regulation and quality control. There are NO quality standards in place for industrial oxygen... you never know what that person who had the bottle last hooked it up to, and it is common to find relatively high levels of moisture in these products.

There then is the possibility that the cylinders do not get vacuumed appropriately. What happens when you then purchase this product for breathing and you take in a lung-full of pure Nitrogen? Not good. It's too easy for something like this to happen, and it's just not worth the risk.
That being said, you will need a prescription to purchase medical oxygen. If you find a gas supplier who will sell it to you without one, you should be wary of that supplier and their products.

i prefer to get my O2 from taking deep breaths. helps with nausea, headaches, etc. and it's FREE!
