Frank,
Thank you for the input. A good DR in competition situation can only be explained by stress, right?. I followed the posts by Sebastian M. about that before. Very interesting and logic. Catecholamine hormones are released, peripheral vasoconstriction is activated and peripheral muscles therefore switch to anaerobic metabolism. So, oxygen is preserved for the central nervous system. For the dive I described yesterday, I tried to imagine going into very cold water and having a very tough task ahead. Nevertheless I waited for the DR and it came very late. I felt stressed when I started the dynamic, but somehow relaxation set in and my legs "didn't close"...
Interesting that you say Frank that you don't think too much in CO2, but in O2 stores to kick the diving reflex. How come?
