A clinical-register reading room. We explain the mechanisms the performance category talks about — signaling, recovery, adaptation — at the level of how the system works. Nothing else.
Training breaks tissue. Recovery rebuilds it. Between those two events sits a signaling cascade that decides how much adaptation you actually keep. Understanding that cascade — generically, mechanistically — is the whole point of this page.
The mechanism is the message. The message is recovery.
The adaptation you keep is decided after the session, not during it. A mechanism-level look at the recovery window.
READ THE NOTE →The category uses the word constantly. Here is the physiology underneath it — receptors, messengers, pathways — in plain terms.
READ THE NOTE →Why the largest lever on recovery is also the cheapest, and how the repair cascade depends on it.
READ THE NOTE →Feeling worked is not the same as adapting. The difference is mechanistic, and it changes how you train.
READ THE NOTE →Field Notes is editorial. We do not sell, dose, or recommend products here. If you want the mechanism breakdowns as they publish, follow the notes.
