Can you tell us what you know about ammonia as a factor in fatigue?

So you are looking for a metabolite to blame. Stop doing that. That's not good science.
You are missing the point about glycogen depletioon. It's a depletion of the most powerful fibers. Yes we can use them again after a rest, this is because accumulated lactate can be reconverted to liver and muscle glycogen, a process known as gluconeogeneis. There are many gluconeogenic pathways.
Your basic hypothesis seems to me to be that no-one has a hypothesis. I'm sure that if Ross Tucker had the time, he would be polite, but you aren't giving him anything really profound are you? Just a load of Newtonian physics equations and a suggestion that if we can't blame 'lactic acid' we must find another culprit. How many other half baked hypotheses do you think he gets asked to read?
"Surely glycogen depletion of the most powerful fibers ..." sounds like another half baked hypothesis.
Forming hypotheses, even wrong ones, is not bad science.
Looking for evidence, even for wrong hypotheses, is not bad science.
The Glycogen depletion of the most powerful fibers hypothesis relating to the very fast starts and extended high speed endurance of 400 and 800 meter races, has been around a long time. It's common sense. Hypothesizing that there must be some unknown metabolite which causes fatigue?..... Not so much.

Great interview with Steve Cram - says Jakob has no chance of WRs this year
RENATO can you talk about the preparation of Emile Cairess 2:06
Hats off to my dad. He just ran a 1:42 Half Marathon and turns 75 in 2 months!
