Hi Gabriel,
I have read that before about the tests done with cycling sprints. The main advantage with Bicarb loading is that it delays the build up of lactic acid. I read that you would actually fail a doping test because it changes your blood PH to outside allowable limits.
I can't see how it would help in any way to hold your breath longer, especially for a static. It might possibly help for a dynamic or depth dive to reduce lactic acid build up.
But, I've seen a discussion before on this forum about changing blood PH, can have both positive and negative effects on breath hold time. Think Eric Fattah has already done quite a bit of research on the subject.
It's possible that it does help and maybe some people are already doing this, who knows.
I was going to try it out myself but not sure how safe it is. Took Bicarb once before exercise and it makes you burb big time !
Tastes really salty.
Cheers,
Wal
