Dynamic categories

[Blue Straggler]

"Back in the day" (I am thinking of Andy LeSauce, Maren Isgkeit, Natalie Desreac etc) there used to be separate dynamic records for 25m pools and 50m pools. I assume that this has changed now - when and why? Are all AIDA dynamic records/competitions held in 50m pools now?

I don't know when it changed - probably the same time as scrapping salt vs freshwater rankings? The rules state that they can be held in any pool 'larger than 25m' though the recent AIDA World Championship was held in a pool that was 18cn less than 25m - hence Dave Mullins doing 248m and not 250m. Bill Stromberg did comment that the rules would be changed to acomodate smaller pools, as this may penalise those who train in older facilities and if I remember correctly the change will be '25 yards and over'. Anyway if applied for, and as far as I understand any pool can get a waiver if accepted by the AIDA board - especially as some don't always meet the shallow end depth requirements.

Hope this helps.

It's a problem with the pools in Egypt. It's very hard to find a pool that is exactly 50 or 25 meters. 2006 at the AIDA WC the pool was 49.73 meters and this year the pool was 24.85 at the comp side and 24.90 on the other side.

What AIDA do is simply ask if we would like to have the WC there or not, sometimes there is no options and we have to accept the pool and give a waiver. BUT remember that we calculate what the pool is of course, not what it should be. So this year 2 laps was 49.70, 4 laps 99.40... etc. 10 laps 248.50 (Mullins DYN)

From the first of January 2009 the minimum will be 25 yards, (22.86 meters). ...if the AIDA Assembly vote yes for this, that is

have a nice day

Excellent. That will add a few more pools to the competition circuit.

I think the no-fins divers get an advantage with the push off in smaller pools and with fins are better off in a longer pool. For that reason Dave Mullins did an even more spectacular world record

In the UK i've noticed a number of our pools that are less than 25m (normally 25 yards) and a couple of the 50m pools are only 1.00m in the shallow end. I was going to ask for a waiver for that too as its a bit shallow under the rules. Can you chuck that in for us to Bill ;-)

As a point about the Salt Water / Fresh water dives I remember old records you could use the fact that most computers are Salt water calibrated to work out the actual depth you are diving in Fresh water by multiplying your fresh water depth by 3%.

So a competitor doing 60m on the computer in salt water did 60m depth
A competitor doing 60m on the computer in Fresh water did 62m depth.

Can this rule still be used?

Salt or not... it doesen't matter.

AIDA Judges verify the depth of the dive by measuring the length of the descent line. AIDA International does NOT accept the reading from a dive computer as verification of depth. Dive computers are only used by AIDA to give an estimate of the dive profile.

The length of the descent line is the same what ever water you dive in. This of course if you do it in the right way with decent weight calculated in the correct way.

Normaly it's easier to dive down in fresh water, but harder going up. And you will experience a sort of a contrast in salt water. But the distance between the surface and the bottom plate is the same.
