Beta-Endorphins response

[anthrax]

What is the relationship between beta-endorphin and exercise ?

ie what leads to the more release of beta-endorphins, serotonin and dopamine ?

Intensity ?
Exercise time ?
Oxygen consumption ?

It seems, for my personal experience, that anaerobic activity is producing the most significant endorphin response

Any idea ?

So what ?

There is no endocrinologists on EF ?
No experts ?
Nobody with just a slight idea on the subject ?
