Freediving RV training part 1

[@vlpanic]

If rest is training then I am overtrained :) Jokes a side, great videos and huge knowledge Aharon, thank you for sharing it with us. Every single word make sense

[@thessalonikifreedivers7750]

Thank you, friend, for knowledge sharing. Wish you health from Thessaloniki Greece.

[@AharonSolomons]

Thank you

[@CK141]

Very wise words from arguably one of the world’s foremost trainers. Thank you Aharon for sharing.

[@sphericalme1]

Man this is brilliant. You are so well spoken and make everything so clear. Thank you for doing this. I could listen to you speak all day.

[@Carlosyage]

Respect and thank you for sharing your knowledge. Best wishes from the Caribbean side of Colombia!

[@vandanos8745]

Great ,thank you very much for the information!!!!keep up the good work!!!

[@cevisuals]

Good to see you healthy with the same twinkle in your eye as always my friend...

[@mohammedkhelladi4570]

Thank you

[@samojeranko475]

Amazing, thx Aharon!

[@AharonSolomons]

thanks Samo much appreciated

[@BonaireFreediving]

outstanding! Thanks

[@obakhanjones2869]

This guy is pretty grumpy. It’s a good thing Freediving is becoming more popular because ppl are proving that physiology is such a vast spectrum that calls for various training methods that actually do work. I have heard soo much conflicting information from different 100+m divers that I respect that some ppl just do it different.

[@deepbluewaterful]

I was able to do the rv with the mouthfill for 4 times compensation only to -6 meters max and have the mouth fill volume enough for just 4 times ... do not know how to improve...? Could you answer please
Anyhow Im now at -40 m easy dives(full inhale no fills)

[@sophiebellin3787]

Very interesting ! Would you recommend RV training for people using frenzel only ? I'm a 60m diver

[@AharonSolomons]

Not my RV training

[@AharonSolomons]

not compatible with what I teach

[@oricohen6804]

Aharon thank you for sharing! learned a lot from the video. I know where you stand on FRC training, but with all the respect I have to ask you... I found that FRC can be productive on the primary stages of learning freefall (position, relaxation) without being at great depth. what do think?

[@AharonSolomons]

Whatever works for you

[@garygao7658]

Agreed almost all,but I cannot convince myself blood shift comes quicker, I think it caused by the water pressure, in my opinion it’s another flexible training but no
blood shift involved , thanks for sharing, best wishes.

[@AharonSolomons]

Please read up about the triggers for blood shift do you imagine they are different from spleen contraction ? It would be strange because in 20 years none of my trainees have experience lung squeeze

[@AharonSolomons]

Then you must also believe that the alveoli do not collapse during RV descends. I would like you to explain your version of physiology in this case. Or the capillaries also fail to dilate? You have some interesting ideas.

[@garygao7658]

Figure out what cause the blood shift must be very good ,do you have some research paper to reference , the resource I found before all about the depth reason including you mentioned a paper.

[@AharonSolomons]

Gary gao Gary you dont have to be a genius to figure this out . if you are begining the dive with only residual volume in the lungs then going through the 10 mt band where you get a 50% reduction in volume ; the maximum pressure differentials , what do you think happens to the alveoli ? and if the capillaires do not dilate the normal 200% as in blood shift , what exactly do you think happens ? The mother of all lung squeezes . Please think before you comment , particularly when you are throwing doubt on what someone else has written

[@AharonSolomons]

Gary gao Gary for God’s sake these are begginners questions , there is very little research in freediving ; for a good reason there expected financial rewards are zero. Research takes time and money and most people like to be paid for their time . The only papers I know of that directly relate to this are Karl Schaeffers’ papers on Bob Croft , but Karls sponsor was the US navy and they may not be available to the public , Also experments done on Tanya Streeter and Fred Boyle in the whirral the Royal Navy recompression chamber in the north of the UK ; circa 2002 . All the rest is peripherial , Per Scholander ( the master switch of life ) , klaus Lundgren ( the lung at depth) , La plongee en apnee Corriol ,, Erika Schagaty , Peter Lindholm . You should know this as an AIDA Instructor ,and the issue of bllood shift or not in RV diving is something an AIDA 2 star diver should have the knowledge to solve . If you understand basic freedive physiology what do you think happens if you go down with empty lungs through the most extreme pressure gradients and dont get bloodshift ? you would get either massive lung squeeze ( pulmonary oedema ) or you couldnt go down . I presume Stephan was your teacher why dont you have a chat with him ?

[@illianish]

Thanks Aharon for sharing your knowledge - it is an absolute treasure!
At 4:45 you say that RV will stop you from exceeding your "squeeze-safe" depth, "because you will not be able to equalize", could you please elaborate on this?

[@AharonSolomons]

Elaborate ? Why not try it ?

[@illianish]

​@@AharonSolomons I did try it.. but I wanted to understand what you said in a fundamental way. What exactly is happening in the lungs that prevents you from going deeper while you equalize only with the air in your mouth. I can not see an apparent connection between the two. Hope I made my question clear ;-)

[@AharonSolomons]

you tense up in reaction to pressure ; then . you cant equalise .. untill the pressure releases you ,you wont go any deeper .

[@illianish]

@@AharonSolomons thanks!

[@AharonSolomons]

illianish its simple its like a punch coming at your midrift as it gets closer you begin to tense up . The water squeezes you and unconsciously you tense up then you cannot equalise , so you are forced to return to the surface

[@Ondrik1471]

(just watched the video till the very end and assume you will cover this question in the next one, but I just leave it here in case of not)
Hi Aharon! Thank you so much for sharing your views on this topic. Amazing insights as always!
Can you elaborate on what are the benefits of taking a mouthfill ON the sourface and what is the issue with taking the mouthfill in 15-20m (depending on depth)? The later is widely used in most (if not all) freediving manuals.
I always thought that the logic behind taking MF in 15-20-25 meters is that beyond this point the diameter changes of the air volume are not that significant as the first 10 meter (boyel's law) and that if the freediver takes the MF beyond this point, it is more efficient and more likely that the freediver will reach the desired depth with some remaining air in his/her mounth. Whilst when you take a MF on the surface, at 10 m. half of the air in your mouth is gone already.
Would be glad to hear your thoughts on this. Thanks again for you great work!

[@galloyeah]

You're missing an important point. He's talking about RV dives. Not full lungs dives. Obviously going for a deep dive on full lungs with MF would require you a recharge somewhere between 20 and 30m.

[@Ondrik1471]

@@galloyeah Thanks, but no, you did not pay attention 10:49 "...all this nonsense on full lung dives of taking the MF at 20, 25 meters it is completely unnecessary, why would you do that? train yourself to hold MF and the best way is RV training."

[@galloyeah]

Thanks! Interesting, well then again he must be talking about Mouthfill training, not dives below 100m with only MF. Every top freediver that doesn't reverse pack charges from 0 to 10, and recharges all the way til 25-30. Some of them even deeper. What do you do?
