Apart from the beautiful new training space right on the beach, as before we have the beautiful blue right in front. Which is why we came in the first place.
Sebastian Murat was recently in Amed, Bali, while preparing for his 703 ft no limits world record attempt.
Knowing that Sebastian Murat is not really an exponent of the Yogic school of free-diving I was expecting an uber-focused competitive athlete. It was a pleasure to hang out with Seb and see how little he is focused on the numbers.
I have always wanted to to put some questions to him regarding his intense research into the Mammalian Dive reflex. Our conversations were quite long and meandering so I’m not going to offer a transcript here.
Just some of the interesting points as I see them.One thing that I was particularly interested in was that since he started training using FRC techniques Seb has had no incidents of lung endema (squeeze) that he is aware of. This coincided with giving up on lung packing. Something we looked into in a previous blog
Basically the question is why would one dive with less air, especially on extremely deep dives.
The simple answer is that the MDR is stronger, which means that the body is more efficient in it’s use of O2. In Seb’s view this increased MDR balances the fact of going down with less air.
Another benefit is the lack of Nitrogen Narcosis at extreme depth and lesser likelihood of Shallow Blackout on reaching the surface. The decreased expansion of the lung volume upon surfacing means there is a less dramatic drop in air and blood. With a strong MDR there is also increased brain cooling which reduces O2 consumption.
Which is something that Seb is spending a lot of time doing these days, researching the cooling effect on the brain and exploring the MDR as a short term hibernation. A lot of Seb’s energy these days goes into medical research, something which is great for the rest of us.
I want to come back to some of this stuff in greater detail in another blog. To see how Seb is doing check the french job website.
With so much energy and time going into getting the space finished I just got round to looking at the website for Sebastian Murat’s world record attempt.The publicity around it is all a bit hyper for such a cool and down to earth guy, we wish him the best of luck with the dive and the circus around it.
Recently Sebastian Murat was with us in Amed, while training for his no limits world record attempt at over 700 feet.
Some people newer to free-diving may not have heard his name, but Seb is one of the most interesting guys in the sport, devoting the last years of his life to exploring the Mammalian Dive Reflex(MDR). His training and deep research has focused on the MDR in all its aspects, investigating the medical applications of the MDR and breaking and attempting records using less than a full lungful of air.
This attempt at over 200 metres depth on one breath will be performed in FRC, that’s to say less than one breath. This is something that many would consider as counter intuitive and maybe even a little insane.
Unsurprisingly I had a few questions for him and even managed to drag myself away from the building site to hang out with him and test his no limits retrieval system.
His approach is decidedly minimalist. Basically it involves grabbing hold of some rigid buoys built to withstand high pressure. When they are released you shoot to the surface.
He’ll be using this beautifully simple system to rocket to the surface from 200+ metres.
Another interesting thing about Sebastian Murat’s approach is that since starting to dive using exhale/FRC techniques he has never had a squeeze. Something he previously had a couple of times when practising full lung diving with packing.
As there is lot of interesting things to be learnt from a career spent studying and developing the Mammalian Dive reflex, we’ll come back his ideas on another blog shortly..
Weather has picked up very nicely the last few days. The peak of Agung has been clear, the sun shining and the water warm and clear. The last few days have seen some very pleasant free-diving. All hail the return of sunny days…
These will probably be the last pics before the place is all shiny, bright and ready to be filled with stuff…
This space will be used for free-diving theory, yoga and meditation practice and then for hanging out later on…
At the moment, we have the ugliest front in Bali. But in one month (or ten) this ugly place will be the first purpose built free-diving/yoga space in Bali…watch this space.
The mammalian dive reflex (MDR) is part of our evolutionary heritage that all humans possess to some extent. In extreme situations such as near drowning it helps by increasing our survival time, but normally in most people it is a reflex that lies dormant. Though dormant it, like most reflexes, can be honed and developed. (more…)
