Do you know what MDR is?

[Ben Gowland]

Naiad - do you pack (It would explain the high heart rates)?

 

[naiad]

I sometimes pack, but not always. My heart rate is high anyway. When I am doing normal everyday stuff, it is about 100. My lowest resting HR is 64, but it is normally 70-80 if I am relaxed and doing nothing.

But in the end so what - it is about maximising the response (reflex or not) so that we have great dives!

Not sure to what degree and what focus you meant to imply with "so what". However, to emphasize what I find important in working on this topic, the "so what" that I am working under are the following ideas:

1. Teachers only have vague, loosely interrelated, and inconsistent information to work from; creates a lack of confidence in presenting and elaborating this information.

2. Students put their trust in teachers, yet the topic in its unorganized and vague state, is arguably promoted as the most important topic to convey to students. This is fine if everybody is aware that this is the current state that the topic needs to be approached from, but instead this topic is taught as though there is a well defined and conclusive quality to it.

3. Because of its vague state, we see relaying of false/imprecise/inaccurate/inadequate information by teachers and students. This propogates exponentially.

4. promoting MDR at the forefront of our knowledge of freediving, yet, without any reasonably consistent or detailed comprehension of MDR, followed by lots of assumptions, weakens the stance that the freediving community has the ability to develop and discern relevant information. This can hinder the community from being taken seriously or professionally outside the community in this regard.

5. maximizing requires as much information as is available and drawing the relations between such information. Yet, if the information on MDR is not organized and clarified, then relations can not be drawn accurately and there is little ability to assess whether maximizing based upon currently available information is actually taking place.

6. if the information was organized and clarified then other previously unknown explorations and deduction may readily advance towards maximizing MDR.

So, at the end of the day, I see clarifying, organizing, and expanding on the concept of MDR as being the only way for freediving participants to collectively have access to digestible information towards "maximizing" MDR.

I agree. One thing I can think of to promote the above stated objectives would be to propose and run some very simple experiments, conducted by as many DB freedivers as would be willing to cooperate in such effort. I'll leave it to you eggheads to propose such experiments.

I would be glad to help out.

I see the problem within the 'Advanced' Freediving community in terms of accuracy of information, but:

The generally accepted definition (from Marine Mammal Science [MMS]) is not as defined as you think it should be. It is simply:- Bradycardia, peripheral vasoconstriction & 'blood shift'. Whether it is a response/reaction or a true reflex, or whether these are apneic or cold or pressure reponses/reflexes has never really been looked at in depth in MMS as it is not yet of much interest as they are still trying to study the magnitude of the responses rather than the controlling mechanisms.

Sadly science is too far behind the freediving world to be of much use to us.

Good summary of the state of affairs outside the freediving community.

This state of affairs is actually fine. And only further supports what I am suggesting. Identifying what we do not know is knowledge in and of itself, therefore, is as important as specifying what we do know and what we suspect. It is how clearly, precisely, and accurately we identify and categorize the various points related to MDR that determines the quality of the information.

The quality seems to be low at this time. I am simply hoping we can take what we know, don't know, and suspect and form it into quality information.
