Supertraining

Very well, but in an interesting article: by Hunter, S,K; Duchateau, J,
and Enoka, R.M: Muscle fatigue and the mechanism of task failure, Exercise
and Sports Sciences Review Vol.32, Nio.2, april, 2004, pg.44-49 it states
that the fatigue is task dependent, which taps into our own experiences
that one might have CNS fatigue, not being able e.g. to lift 1RM in squat,
but still at the same time being able to lift the 1RM in benchpress ......
Ralph's interpretation hints in the direction of a strong perceptual/
motivational being involved.
Suppose somebody is extremely tired like after running a 10 k and
collapses on the track, not being able to run one more step: muscles
depleted, brain exhausted... what would happen if this persons life was
seriously threatened all of a sudden? Would he be able to get up and
escape or just lay there ... Would this then be mind over matter?
Probably CNS fatigue is partially explained by diminished cortical and
spinal exitability.
