Ella’s Physiological Interpretation

This was a fasted VO₂max-efficiency session on wet-clay terrain with steady aerobic control and a small ketone rise (1.9 → 2.2 ppm). Compared to the earlier Skinsuit session on 11/28 — which produced higher environmental heat stress, stronger metabolic swing, and AUTOPHAGY_MEDIUM — this hike expressed a different adaptation profile: engine stability, lower systemic strain, and improved movement economy under technical footing rather than metabolic depletion. Pre-hike sleep showed high-quality readiness (stable autonomic tone, strong depth), while post-hike sleep showed strain with compensatory deep sleep, meaning the body prioritized tissue repair instead of pushing ketones higher. From a longevity lens, this session maps to HIGH_QUALITY_STRESS · ECONOMY_STABLE · MODERATE_STRAIN · ENGINE_STABLE — a durability-builder that strengthened aerobic capacity, VO₂max adjacency, and technical trail efficiency without triggering a full autophagy event.
