“The AltiPower Personal Hypoxicator uses your own natural breathing process to produce reduced oxygen (hypoxic) air. Continuous breathing using AltiPower, with its patented, semi-closed, respiratory circuit, gradually decreases the oxygen content of the breathing air. This replicates the conditions of high altitude and with it, the benefits of alpine-like air.”
I may be climbing a 10,000 ft mountain later this summer, and coming from zero elevation Miami, something like this may help. However, I’m failing to see how this works any differently than a paper bag.
Best piece of information from the Altipower site, the World Anti-Doping Agency president’s name is “Dick Pound”…seriously.
