But yes, it's pretty standard. Almost all freedivers hyperventilate.

If a novice freediver starts hyperventilating before some of their apnea adaptations have developed, then there is a greater risk of blackout.

It is something i have really noticed, a lot of top divers are using hyperventilation before their swim somewhere in the breath up. What is the specific 'apnea adaptation' that would allow an experienced diver to hyperventilate but not a novice?

Are the top divers now recommending it as a technique??

Well done again Alan, not bad for an off day ;-)

By most of the 200+ club, who do you mean? The three NZers definitely don't, for a start.

As far as I'm aware, there is no physiological adaption that would make hyperventilation more appropriate for an experienced diver. They may be mentally better able to handle the side-effects, as they know their limits better. As for recommending it, there is no consensus on what the best way to dive is. There seem to be some broad strategies governed by what divers you train with regularly, ie here we aren't really into warmups or 'forced exhalations' for our diving. Mostly, we get in the water, pack then swim. Getting our German tourist, Clements, for a few months showed just how different this is to the 'German Way'.

I edited the post. I used a pretty broad brush for an elite few.

I was quoting from Dave Mullins and following that up though to be fair.

It is the case though that a number of comps ive been to and in clips i have seen some really good performances with forced exhalations which is a level of hyperventilation. Whatever happened to the bohr effect, it seems so yesterday.

Like I said, the people we train with and around influence our perception of training and performance characteristics. The only competitor I have seen with my own eyes who ventilates heavily was Clements. His static breathhold was in excess of six minutes, yet he struggled to break 100m. To contrast, I have never done a six, yet I can do

180m dynamic

. Maybe the hyperventilation is more beneficial in static than in dynamic?

Alan: Have you tried long swims with just tidal breathing before? No forced exhalations or long, deep breaths. It will feel a bit harder, but you may find yourself going even further! Congratulations on the dive anyway

Well I guess it made an interesting thread discussion anyway. I have never tried > 150m without some sort of warm up and THREE forced exhalations. Might well give it a ago. Five was excessive and resulted in a poor dive. Will do better in future - I promise. :-( Want to get a few more 200m done and then some 225m. Psychology is just such a HUGE factor - I need to learn to relax in my freediving - and that is something that for me is not going to be easy.

Thanks again everyone.

Regards,

Alan

Best of luck with the 225, that'll be some hard slog to get there! Psychology is always a big part. I've found regular max attempts help, in that I know I can do it. Then again, what works for one person might not for another.

[AJRBARBER]

Entirely agree - I've never done a maximum per se - we have always agreed the distance before and that is what I do. 225 is going to be interesting - also need to work on fitness but hey ho - one step at a time (or 25 with a little luck :-))

Congratulations Alan. Very well done.
