Hi stef,
i found this link by searching deeperblue
The Frenzel Technique :: FDTF :: Freediving Team of Finland
this document about frenzel and mouthfill technique is quite detailed and there is a nice exercise for decoupling soft palate and epiglottis, using an inflatable ballon. i started to do it recently, the result till now is rather a pain in the cheeks from hours of blowing the ballon than a real mastering of the technique
. anyway i hope i will improve with time
The fact is that i think i CAN do the techique already when in the water and diving, the only thing i am sure i can NOT do is to take a real full mouthfill and aply the technique with it. as soon as i fill my mouth till the cheeks blow up well i am not able anymore to keep the epiglottis close and force air in the tubes by using cheeks or tongue. with just a little air in my mouth all works well, but of course i dont get very deep with the pour mouthfill.
Any suggestions? Just more training needed?
cheers,
Ivo
