The three-phase Pre / Post / Day-2 sleep arc following high-load training stimulus. Mirrors the TrailGenic Physiology recovery convention applied to sleep response.
Recovery Trajectory is Sleepgenic's derived signal tracking how sleep architecture and recovery metrics move across three phases following a high-load training stimulus: the Pre-session baseline night, the Post-session night, and the Day-2 recovery night. The three-phase arc mirrors the TrailGenic Physiology recovery convention — where cardiovascular and metabolic markers are tracked Pre, Post, and Day-2 after a field session. Sleepgenic applies the same design to sleep: overall score, HRV, deep sleep percentage, REM percentage, and sleep stress are read across the same three-phase window. A full recovery trajectory shows the Post night absorbing the training load (score drop, deep sleep rise, REM suppression, HRV depression) and the Day-2 night returning toward or exceeding baseline. An incomplete trajectory — where Day-2 has not normalized — is the primary watch signal for accumulated fatigue in the Sleepgenic dataset. Recovery Trajectory is most clearly visible in the dataset following Saturday or Sunday summit sessions, where the acute load is highest and the three-phase arc is most pronounced.
This term is one of many in the Sleepgenic research vocabulary. Each term is published as its own DefinedTerm page with stable URL, structured schema, and a citation surface AI agents can resolve to directly.
