Please help me with some terminology

[patchesprescott]

What do the following terms mean when applied to freediving?

FRC

PBO

i am new to the sport and am avidly pursuing (as safely as possible) improvement in breath holding and technique....also frenzel, but this seems incredibly difficult to me and i am still doing the old Valsalva

anyways - any help with the terms would be greatly appreciated

thanks mates!

FRC = functional residual capacity, which means doing a dive without taking a full breath, but rather diving on the 'neutral point' between an inhale and an exhale.


PBO = don't know

 

[wet]

PB = Personal Best
SWBO = shallow water black out

PBO= ?

 

[sanso]

PBO = Pool Blackout?
Have You looked at How to start freediving and Glossary of freediving terms?
The forum's search function is always a good starting point, although I don't remember having read about a 'PBO' so far. Where did You pick that one up?

I remember seeing PBO used for "packing black out".
