I shared an article a while back on decision fatigue. The article came up again in a recent discussion, and another idea was raised, this time from the fitness/training world: Acute Training Load vs. Chronic Training Load.
“ATL – Acute Training Load represents your current degree of freshness, being an exponentially weighted average of your training over a period of 5-10 days…
CTL – Chronic Training Load represents your current degree of fitness as an exponentially weighted average of you training over a 42 day period. Building your CTL is a bit like putting money in your savings account. If you don’t put much in you won’t be able to draw much out at a later date.”
This seems like a very fertile idea to me. The language here is very control-theoretic, and the idea seems to be basically about separating time scales of training in a useful way. It also seems to relate to what I think of as the raise the floor/raise the ceiling ways of increasing performance, which I talked about in the context of mindful learning curves.
The interesting question, as a friend of mine put it, is whether decision-making skill (and therefore decision-fatigue limits) responds to training the way our bodies do. I don’t mean this in the sense of gaining experience. That of course happens. I mean, being able to go for longer before performance degrades.
I think the jury is still out on that one.
