Central nervous system fatigue: an enigma or lack of proper definition?

CNS fatigue: how many time have I read that term in the messages this
group.

But did anybody ever wonder what the central nervous system is?

Just a quick look at Wikipedia: The central nervous system (CNS) represents
the largest part of the nervous
<http://en.wikipedia.org/wiki/Nervous_system>  system, including the brain
<http://en.wikipedia.org/wiki/Brain>  and the spinal cord
<http://en.wikipedia.org/wiki/Spinal_cord> .

Looking at this definition “fatigue of the spinal cord” or
“fatigue/exhaustion of the hypöthalamus-pituitary gland” or fatigue of the
“autonomic nervous system’ could also be called central nervous fatigue, or
do we just mean “fatigue of the brain”, “fatigue of the neocortex” or
“fatigue of the motor cortex”? Is the old term “neurasthenia” of
“psychasthenia”  the same as central nervous fatigue.

Before we throw this term around let’s first define what we really mean, no
miracle nobody comes up with a solution for a problem that is so ill defined
as this one.

Onderwerp: [Supertraining] CNS Fatigue (Was: Question - Rest interval
between sets?)



CNS fatigue seems to be a bit of a black box. Is there
any real scientific understanding of it that addresses
it in the way it typically is discussed by coaches, or
is it just an explanation for declining performance
when no other cause can be found?
