Hmmmm.... I stand corrected. Sort of.
The Altipower Pro kit has you hold a mask to your face and rebreath your exhaled gas, thus progressively reducing your inspired fraction of oxygen to simulate altitude. The filter scrubs carbon dioxide from the gas so that you're not breathing a progressively increasing fraction of CO2. You monitor your oxygen level with a pulse oximeter. It's self-limiting, if you pass out from hypoxemia, you drop the mask and start breathing room air.
Interesting concept... in theory.
1. You would have to breath from this device for hours at a time to have any significant effect on hematopoiesis.
2. You cannot sleep with this device because you would have to strap it to your face, a risky endeavor without external cardiopulmonary monitoring.
3. The "proof" of its benefit is primarily in the form of testimonials (in magazines like Shape!), and testimonials are well-known to be the least reliable form of evidence.
4. The only pseudo-scientific publication quoted by Altipower Pro found that intermittent hypoxic training is only
likely to be beneficial, and that the authors
suggest that non-elite multi-sport athletes should expect such training to enhance performance.
All in all, extremely sketchy "science," extremely sketchy "proof," and an extremely high price.
The Power Lung does nothing but exercise your respiratory musculature, which shouldn't even be an issue if you are fit enough to go to Denali in the first place.
So I repeat my original statement in regards to simulated altitude training: "No such thing."
