Talked to a guy in the Human Performance Lab at the University of Calgary doing studies on the relationship between time spent in a hypoxic tent (http://www.hypoxictent.com) and performance of high class atheletes.

Has anyone heard of freedivers engaging in this type of activity in the week or so prior to an event to increase performance? more red blood cells -> more oxygen -> longer time underwater??

I am going back to do some preliminary testing of my lung capacity with him and will ask some more questions if anyone has any.
Hi Jeremy

My wife is involved with a company that does hypoxic training for both human and equine athletes. I have done one of their interval hypoxic training courses and the results were great.

This was before I started freediving but I experienced huge improvements in terms of my overall cardiovascular fitness and my air consumption on SCUBA dropped by about 25%.

I recall Eric Fattah mentioning hypoxic training in the past. I hope he will offer his thoughts again. I am sure that it would make a difference to a freediver, if only in terms of the fitness gains.

I will try to do another course soon and see how much of an increase in performance I get during freedives and statics.

In terms of the time before an event, the course we did was done over a month, we noticed an improvement after about 2 weeks and a big difference towards the end of the month. I don’t know if a week will make any difference as it takes time for the body to adapt to the simulated altitude.

I can see it now, HEADLINES: Freediver found dead in home w/ plastic bag tied around head, apparently trying "Hypoxic Tent" method to increase apnea endurance. Please guys don't try this at home. I know someones already been thinking it.;)
