Ella’s Physiological Interpretation

Over the past five weeks, repeated fasted alpine efforts were absorbed with stable cardiovascular control, consistent negative heart-rate drift, and minimal anaerobic contribution, indicating durable efficiency rather than accumulating strain. End-ketone elevation and retention remained strong, reflecting preserved metabolic flexibility despite shorter exposure windows and colder conditions. Recovery followed a predictable pattern: Day-1 autonomic strain with preserved deep sleep, followed by Day-2 HRV normalization and improving REM, keeping recovery debt bounded and non-accumulative. Altitude stress was increasingly absorbed at lower physiological cost, while refined movement efficiency constrained mechanical load. Overall, the system reflects a stable, consolidated engine — stress is applied deliberately, resolved cleanly, and supports repeatability rather than chasing incremental adaptation.
