Does smoking lower your SCR?

1 minute 15 seconds. i think SAC rate and breatholding are semi-orthogonal, though...

You did 1 minute 15 seconds? Were you a smoker at one time?

Semi-orthogonal?

1 min. 45 seconds. We used to do this as kids.

I felt I might have squeased out 5 more seconds, maybe. Bet you could have gotten a few more seconds? Damn, 1 min 45 sec is very impressive . Waiting for the 3 minute person to surface.

50 sec fisrt try. 1 min 5 sec second try. :shakehead

I need to work on my technique.

1 minute 20 seconds my second try. I felt I could go no further.

Sitting here i can do 2:05 minutes without too much effort. I have done over 3 in water before. I guess maybe it's because I was immersed in cold water. Mind you I am not burning O2 sitting here.

I am a former smoker who gave up 3 years ago after smoking from age 12-29.

Just keep doing it. Sit there for 3 minutes first, breathing in as slow as you can, throught the smallest hole you can make with your lips. Try and make the intake and breathing out last the same amount of time. This oxygenates your body.
Then after 3 minutes, hold the long intake, close your eyes, and try to acheive a sense of complete relaxation. You will eventually get "spasms" but they pass. on land they are not dangerous because you will simply breathe when you have to.
In water once I hit my second spasm I go up. You can learn to control them after a while...

I just did 2:04.

Hey, can I play?

nope.

Semi-orthogonal?

probably not 100% prective of SAC rate. i.e. my breatholding is lousy, but my SAC is starting to get respectable...

Hmm... I've never tried pushing through the "spasms" before...

Anyway, this is what I was meant by semi-orthogonal -- I've got some decent SAC rate lowering technique; a lot of which is just comfort in the water -- but my breatholding technique is poor.
