Regarding the equipment expand a lung..
Can anyone confirm if this equipment really improve your apnea?
I read somewhere that in some cases it even decreased the time due to a possible decrease in the elasticity of the diaphragm muscle. It would get stronger but in some cases less elastic.
Any other gadgets to recommend for training?
Any good heart rate monitors?
Or any other thing to monitor your progress?
Thank you.

Try the search function (top of the page). There has been a good bit of comment on all those fine toys, polar especially
Heh heh... Walrus is talking about a spam post that was removed, not cdavis's comment.

Though now you mention it I am a fan of the Polar, just wish it recorded a higher sample rate dammit :D
Did a search but unfortunately couldn't find anything about the Polar product. These gadgets are a complete surprise for me, never heard about them before. Not even sure if I understand how they work and what are they supposed to do.
They are heart rate monitors - you strap them around your chest and they feed to a wristwatch. You can download the results to a computer later. Very popular with cyclists and runners. They're also water resistant to around 30m, depending on which model you go for. My model is water resistant to 50m, but the chest-piece is only resistant to 30m :duh
I was actually asking about the Expand-A-Lung product. Thought that Polar was something similar. But you were talking about the Polar wristwatches/heart rate monitors, I know well about these.


That's the thingie I was asking about. Does it really work?
Hello Everybody,

Actually, I'm using the breath trainer EOLOS, and well, the true is that it works. I like it, has a good price, good size, the case is great...

If you want more info about it: Eolos

Thank you!.

I tried one - didn't do anything for me. You might as well breathe through any kind of crushed tube as far as I can see - anything with a bit of resistance does the same job.
I have had some benifits (don't use it anymore for 2...3 years); mainly deeper inhalations in recovery breathing without thought, but I believe there are some hazards for the exhaletion part, search Deeperblue forum on 'power lung' there is a lot to read 4 u :)

Ciao Pim
You might find this interesting (or very..very boring) its a bit dated but I’ve seen quite a few medical studies that seem to support the use of the toy.
