Hypocapnic Blackout...

[AlanC]

1. Why is high CO2 the limiting factor to Dynamics (Alanc post)

Co2 is what gives your body the urge to breathe and at my current level of ability (1:30-1:40) i think high levels of Co2 is limiting me before i get low on oxygen. Obviously the higher a Co2 tolerance you can build and/or the more you can purge you would eventually meet you O2 limit.

[too many to list, here are some]
1. Avoid vasodilating foods

That doesn't seem to make sense to me... Is it a typo? (Vasoconstricting instead of vasodilating?)

Either way, what sort of food are vasodilating? (Or vasoconstricting?)

Thanks.
