hypoxic swim training for high altitude

I live at 3400' and have an Oly race up over 7000' next month.  Last week someone at the pool gave me the advice to swim while taking limited breaths to simulate the lower oxygen environment; this is how he trained for flagstaff races in high school swim team and he said it worked well.

What has your experience been with this type of training?

When you inhale after holding your breath, the air is just as thick as it was previously. By merely holding your breath you wont trigger your body to increase hemoglobin and red blood cell levels. If you want to adapt to racing in thin air, then you need to go where the air is thin. Breath control sets will have other adaptations, but not what you are looking for. If you want to adapt to altitude while living at sea level, you either need an air chamber or some EPO. Good luck in your race.
