#3This meshes perfectly with the general view of endurance athletes that performance is largely mental. If fatigue was strictly limited by lactic acid buildup then your state of mind wouldn't make such a dramatic impact.

There are different kinds of fatigue though.
When I go running, it's some kind of aerobic sensation, but eventually my thoughts shift when it's time to stop.
If I lift heavy things for an hour, I can also be quite winded but there's usually some gas left in the tank I just know it's better to get some rest and allow muscle to repair.
Some kind of crossfit style workout, yet another sensation.
Sometimes I can take a nap as soon as I get home after the above, especially a vigorous run in the Arizona desert during summer.
Knowledge work has its own fatigue for me. If I go deep into flow state while working on something, eventually I reach a generalized mental haziness, where I want to relax and let my mind wander or be passively entertained.
Usually I have trouble sleeping after intense thinking, mind still firing but not effectively. I just want to "chill" and watch TV or do something simple and rewarding like clean the house to try and bring it fully out of gear.

Lactic acid buildup does not have the relationship to fatigue that you are implying. Common myth. For more and in from far more knowledgeable persons than me:

#6Anyone who has gone to the gym after a protracted absence and loss of fitness will have some intuitive understanding of this. Your brain hasn't quite gotten the memo that you're not in the shape you used to be, and it's really easy to over-exert yourself. You feel fine during the workout, then throw up afterward and take much longer to recover.

#7In light of this article, wonder what type of psychological training could be used to complement the typical physical training to improve athletic performance?

#8I can buy the conclusion except that I believe you can only usually tweak performance in small degrees without actually over-exerting yourself, since the central nervous system _is_ in fact an expert on what you are capable of doing safely.

#9If the claim is that muscles don't fatigue, then I am skeptical.
In college, I took a weightlifting class with a bunch of athletes in it. One day, we did lunges (no weight) around and around, in a line like ants. Nearing the end, my brain thought I was totally fine. I cannot stress that enough. Bam, like a light switch, my legs went from 60% strength to 2% three quarters of the way through the last lap. Had the instructor not caught me, I would have fallen right over.

#10'Protection' might be the goal of physical fatigue, but it doesn't work for intellectual effort - what are you being 'protected from breaking' by not being able to write another line of code? Carpal tunnel? In that case, it looks more like it's about conserving energy or rotating to another task after having spent so much time on one task: "A Meta-Analysis of Blood Glucose Effects on Human Decision Making" http://www.gwern.net/docs/2016-orquin.pdf , Orquin & Kurzban 2016
