Thanks to Cris for his second posting on the topic " fatigue '.
With his paper we may be able to discuss and perhaps develop some simple tests for the coaches and athletes.
The goal of a training unit may be , to produce a specific stimmulus to reach a specific respond.
So one may use Cris's type's of fatigue's in his paper to plan and to stimmulate one of the fatigue types.
Even tough it may or is impossible to eliminate one type completely from another , in specific workouts ,one type may still be most dominant.
So we could try to do a brain storming with possible signs of the different types of fatigue and see , which one are good ones , but inpractical and which one could we alter , so we can use it as a help of " controlling " or " measureing " fatigue.
( Try is the key word , because it is a challange )
Let me start with some spontaneus suggestion .
Fatigue Equipment possible test or signe
neuromuscular EMG (handheld) drop of peak
activity

EMS/EMG voluntary contraction
EMG drops.
EMS contraction , EMG
still up .
Possible low of
azetylcholin ?

Metabolic fatigue Lactate Pro trends and lactate
values.
glycometer blood sugar trend
ammonia meter possible protein
catabolic involve
ment .
perhaps other more and more available small lab equipment .

Structural fatigue . extreme would be stress
fracture , but already too
late ( now more overtraining )
Will be interesting to see some suggestions here ( Have to go and find some too )
" I for the moment use LBP drop asa marker of possible structural fatigue in the mitochiondria activity , but I am not so sure , just a trend.
It may also be , that ammonia could be used as a structural fatigue of protein.
Neuroendocrine fatigue :

No ideas yet , but would be nice to get some simple test markers out of here. I think discussion like the once we have may help us over time to get more and more practical ( not school infos ) in and get a head of the game.
Psychological fatigue . again I need some more time here.


Here short an info for Cris There is a nice presentation by: Dr. Alan Donnelly ( physical education and sport science University of Limerick , Ireland.
Titel Cellular fatigue , muscle stiffness and free radicals.

They use voluntary contraction and stimulated contraction to try to quantify fatigue.
I have to find my notes I mad during his presentation.
I just remember , that they use 20 / 50 and 100 Hz to stimulate , but I will try to get back on this as soon as possible. Please be patient.
