freediving at altitude

[lee]

Are there any beginners courses at altitude, I am doing my 1st freediving course at the dolphin in the uk. After this I would like to dive at altitude if anyone could give me some lessons or organise a course in europe or uk I would be greatful.
In Hom delphinus, when j mayoll trained at altitude, his performances at sea level increased.
this is my first post.
I am a willimg learner

ALTITUDE

Lee,

You are invited, may be not in this ocassion (due to shortness of time), but in any other. This week-end www.apneamx.com staff is training at a lake in the crater of a volcano, 80 miles from Mexico City, at 14,000 feet above sea level.

Interesting question.
My country is as flat as a pancake. The highest point being something like 200 meters. But I'm curious to know what to expect when freediving at altitude.
Is there anything you should definitely know before doing so?

Do safety rules changes? Will you be able to go deeper or are you more limited due to the lesser oxygen at altitude (I suspect the latter).

Hi people,
I learned to, and have done, most of my freediving at 1500 metres. I did my best statics while at altitude too, but now I'm living at sea level, and will see what happens when I start training again.
The first time I went to the west coast of Canada to go diving with Freediver48, I was supercharged for about 2 days! My very first dive into the sea was a 10 metre dive with a static to get things churning, and I waited on the bottom for a LONG time before the contractions started. That day I dove easily, despite my unfamiliarity with the sea, but over a few days the "supercharge" dissipated and my haemoglobin adapted to the local ATM. The main difference I felt was that I was already in dive mode, and didn't need to do my standard warm up procedures.
This is why athletes train at altitude for marathons, and why there are devices that simulate altitude training while at higher ATMs.
Remember that the same thing can be accomplished simply by static training at any altitude.
Cheers,
Erik Y.

Back here in South Africa , we do most of our diving at altitude, and on trips to the coast,
I have found that diving is much better when down at sea level.
Statics are longer , and bottom time as well as depth is better that high up in the mountains.

I am off to sea to test this once again, but this time it will take me 37 hours to get there,
for I have to fly all the way to Hawaii....for the Pacific Cup.
I will be leaving in an hour or so....wish me luck .

Good luck Herman, and say HI to the Canucks.....one of them (Brent) is South African.
Best wishes,
Erik Y.

Equivalent Depth

Hi,
I an old thread I posted a formula to calculate sea level performance from altitude performance.
It works for me.
