My friend told me the other day that not only do the pro swimmers train in the high-altitude zones with low oxygen level, but supposedly some train in swimming facilities where they lower the oxygen level some way.Sounds kinda hard to believe.Is that even true or possible to lower the amount of oxygen in pools?Or is it just some BS?

Olympic Training Center in Colorado Springs has a "flume" (swimming treadmill) that is in a chamber/room that can be sealed and pressurized or de-pressurized to simulate altitudes from (not sure how much) below sea level to 14,000 feet (I believe) above sea level.
I have heard that if you want to mess with training and oxygen levels, you are better off living and being acclimated to the thin air of higher altitude, and swimming at lower level.
