Adaptation Rate is the system’s measure of whether the Athlete is actually improving. The Rate is computed per metric per week, against the Athlete’s own True Normal. Mechanical Efficiency moving +0.012 W/bpm/week over 6 weeks is a positive Adaptation Rate; the same shift over 2 weeks is a normal noise band, not an adaptation. Tracked across the four True Normal metrics (Mechanical Efficiency, FTP, Execution Precision, HRV trend), the Rate becomes the input that gates the next training block: positive Rate unlocks supra-threshold work; negative Rate forces a deload; near-zero Rate triggers a block revision.

Protocols: Protocol 10 — Adaptive Workout; Protocol 1 — Zone Endurance

The metric traverses the closed loop: Intent is the .zwo prescription the system computed against the Athlete’s True Normal. Telemetry is the .fit recording of the executed session. Adaptation is the longitudinal movement of the metric itself, logged against the True Normal and feeding back into the next day’s prescription via Protocol 10 (Adaptive Workout).
