underwater hypoxic training can cause shallow water blackouts. Not worth the risk, and not much benefit, for a triathlete wanting to learn how to breathe in and out of flip turns.Which is why I said do it with a partner. And it will teach him how to deal with C02 build up, breath control and how to control the feeling of panic. He can fix it with an improvement in fitness, tumble turn speed/technique, but also psychologically. Your mind is telling you, you need to breathe as you're about to drown, you're not going to drown, you are not breathing for 3 secs, that's it. You tell your mind you will get to breathe in 3 seconds and it gets much easier. This is one of the reasons why people can double their breath holds after doing a 2 day apnea training course.
