Ok. Again.

1) Body Weight changes as an indicator of severe dehydration. The science 
says that 3% o 4% of body weight loss during enduracne competition indicates 
the beginnings of severe dehydration--to the point where gut absorption of 
water is compromised.

2) Portable blood analyzers are now available. Look at muscle enzymes for 
muscle damage, total protein and PCV for indications of dehydration, GGT and 
AST for liver indications, cortisol for stress, pH, glucose, and other 
parameters for half a dozen other conditions.

3) Computerized HR monitors tracked against speed. Working heartrates rise 
with distress, and these heartrates are better indicators than recoveries 
because artifacts, particularly emotion, or lack of it, don't have as 
dramatic an effect.

4) The type of platform New Bolton Center used to use to diagnose subtle 
lamenesses via what they called the "shiver factor" Injuries cause 
proprioceptors to send messages that conflict with commands sent from the CNS 
to control muscle and leg stability and stance--so you get a shiver. Subtle, 
but easily seen on an oscilloscope. 

5) Infrared thermography. 

6) Several other modalities have been played with--researchers at Cornell 
have looked at EEGs for stress indications, for example--some of these 
machines are portable. ECGs would give an accurate rendition of heart 
irregularities. EMGs to measure muscle response. One Ridecamper just informed 
me of a portable device for noninvasively measuring blood glucose, tissue 
oxygenation and a number of other parameters that is under development. 

That's a start. By the time these are tested and implemented, I'll have more.
