frc and contractions

[ktreloar]

Hey crew,

gotta a couple of questions for the frc gurus.... i have started to notice when i do frc statics / 3/4 empty lung statics, as i gradually do more contractions come later and later... for example my first hold they will come around 1.30min next hold 1.45min and then 2.00 mins on the next one... i dont do any breathe up the before hand.. my question is, is this the norm when diving this style? i have read else where on this site that some guys dont get contrations at all on frc... hmm

cheers guys

that do not only happens with frc search for warm ups and study the rest that question has already been answered but by the looks of it u should stick to full inhale by know

 

[DivingDane]

as you do consecutive holds, whether on FRC or inhale you are getting your body's dive response kicked in and you are becoming more relaxed. this is why the contractions are being postponed.

FRC will bring this response on more quickly than inhale.

FRC is a great way to dive and once you have it i find it to be a VERY enjoyable way of diving. just my opinion. i find that i am more "there" at the end of an FRC dive than an inhale dive. if max depth is your aim then FRC isnt really the answer (unless your Sebastian Murat or or Eric Fettah) but is a very rewarding way of diving.

thanks for the info guys...

i have been diving frc for about 8 months now and im already getting better results then my previous inhale dives. Now that i look at it i have gone deeper on frc then inhale (28m on frc not that deep but deep for me :blackeye) bottom times on frc are way longer then on inhale to... i will give the search function a go see what i can find..

Cheers

28m on frc is deep and you need to study what you are doing,

use the search function and find all the post from seb murat

Or maybe the dive response actually gets weaker and weaker. Who knows. Since the no warm up strategy is based on partly this. Not doing consecutive dives and thus getting stronger dive response in the first dive. Search all post by MURAT and learn what a REAL dive response is.
The feeling of easier dives after some warm-ups usually relates to a spleen release (search), which is not part of the original definition of dive response.
In my experience easier consecutive breath holds usually can be traced to the diver being unaware of hyperventilating (ventilating in water under pressure could also enhance the effect of breathing). What is believed to be recovery breathing is actually (volume wise) hyperventilating.

28 thats great on FRC.

sorry, can someone explain what FRC is? I am new to all this so I would like to understand it, thanks.

Great thank you Leven

Sebastian, thanks for clearing that up. i understand that the no warm diving style brings on a much stronger dive response. i think i may have misworded my answer.

more trying to say that the body is getting used to holding its breath and relaxing more thats why it gets easier after a couple of warm ups. i always considered this to be due to dive response (heart rate drop, little bit vasoconstriction etc) but it would seem i'm wrong... time to go back to my notes me thinks.

Spleen contraction releasing blood with high levekls of red blood cells but i only thought this happened when pushing a bit more (past the first urge to breath) as in a BIG dive. but again could be very wrong.

i think 90% of divers hyperventilate if we talk volume wise after a dive and take the exact diffinition of Hyperventilation in to account. would hyperventilation have any effect if you had 2-3min between the end of you recovery breathing and yoiur next dive as in:

surface, recovery breath, 2min relaxed breathing, Dive.

i understand the no warm up thing but i just CANT do it, feels too uncomfrotable. not to say it isnt working just feels CRAP.

What fflupo said. I am a huge fan of frc, but it is a very different way to dive and your body reacts differently than to full lung diving. 8 months is not very long to be doing it and 28 m, while great, is pretty deep. Diving with a very experienced buddy, while you learn more about how you react when pushing your envelope, would be a great idea.

On your specific question, your pattern looks pretty close to mine, normal. On getting no contractions at all, it happened to me once on a full forced exhale practice dive. I was 50 % past where i should have had an urge to breath or contraction or something but felt absolutely no urge to breath. Scared the begebers out of me. Bottom line, FRC is different, be careful.

..i can feel the blood leaving my arms and legs on a exhale/FRC no warm up dive, the mind enters a different stage of consciousness and the performance increases, but the body needs its time to adopt as well as your body-awareness will change, this needs to be done in little digestible pieces otherwise you might get hurt.. not only to mention the equalization

f.e. let some cold water in your suit and you will see the effect of a shock and relaxation

get used to the burning legs

Be sure and read all of Murats posts and the several long threads that go with them, some pretty old. Often, he doesn't write very clearly and reading his stuff is work, but absolutely necessary and rewarding for anyone who wants to pursue frc.

Or just dive and listen to the body

Spleen contraction releasing blood with high levels of red blood cells but i only thought this happened when pushing a bit more

About 2 min apnea needed and spleen fully empty after about three apneas. But if you wait too long in between 7-12 min, spleen fills up again.

Murats says better to get spleen release while doing your big dive and during vasoconstriction. But in that case it will most likely not be a full spleen release.
And question is, how big issue is spleen release compared to a good dive response.

For me recovery breathing means = anything the body wants to breath after a dive. If it breathes more than normal it is not unnormal, it is just ventilating out levels of CO2 ABOVE normal levels.
When you are back to normal you have the option to start a breath up (ventilating or to be medically correct hyperventilating) or just go with no breath up.

But i would advice against a total no breath up strategy since it is so beneficial to do an exhale down to nearly RV and an inhale and go from maybe 14-15% O2 in lungs to 16-17% O2 which is quite a big increase.

Yes Murat style of diving takes the fun out of it. Not recreational really.
I did some good dives inspired by his methods (NR's) but have turned back to warm-ups for a few years, it is supposed to be pleasant at times, otherwise it is hard to keep motivated.

Hey crew,

cheers for the responses.. have had a pretty good read of sub murats threads and what i can gather is that his approach although pretty rough since there is no warm up will yield better results. hahah even though its not to much fun, I have found with serial frc dives even though you might not get results as good as the no warm up approach at least they will be alot more comfortable and enjoyable..

just curious guys whats masks are you using for frc?

cheers

A sphera : very good for frc since it's very flexible and don't ned to be equalized until 20m (for me at least).

 

[fflupo]

minima or non,

anyway a strong epiglottis and a good mouth-fill is mandatory..

i like what sebastian wrote, the murat style is work and suffer

but the benefit you get out will shoot you in a different dimension of freediving and becoming one with your body and mind, the body can tell you a lot

finish your training with something positive
