Getting back to running and building optimum muscle: you can't stay in POSITIVE NITROGEN balance by running excessively for distance, et. al.
You've got to digest 20 grams of protein every 3 hours or look at it like NITROGEN in the system every 3 hours for optimum muscle growth.
There's no way you can keep ahead of your bodily requirements for nitrogen and perform THAT much work. Loss of hormone makes it tough, particularly when they are taking steroids.
I won't go into those aspects now because we covered that on another tape. Distance running can contribute to this over-stimulation of the Adrenal glands – then you have overstressed adrenals – sometimes ADRENAL SHOCK and then the resulting feedback mechanisms cutting down on your Testosterone levels, etc. No growth.
It is only a loss, however, to the degree that they are spending it.
In the meantime they can't possibly get back from Peter what they took from Paul. Fortunately, these glands can rejuvenate themselves with care and nutrients.
They can rehabilitate themselves even if they atrophy. You see this with the varying libido problems a lot of these guys have.
When they get off steroids, for example, their own glandular system slowly comes back and sexual drive returns more, sense of vitality and well-being, etc
