This protocol documents the physiological recovery effects of high-protein and high-sodium refueling following prolonged fasted summit load. Strategic protein repletion activates muscle repair pathways, while sodium restoration stabilizes plasma volume, cardiovascular output, and neural recovery. Carbohydrate moderation preserves metabolic flexibility and accelerates mitochondrial repair integration without suppressing fat oxidation dominance.
Following a prolonged fasted summit effort, the body enters a transient physiological state defined by depleted glycogen reserves, reduced plasma volume, and elevated mitochondrial stress signaling. The objective of post-hike refueling is not simple caloric replacement, but restoration of structural integrity and metabolic stability.
Protein repletion is the primary recovery trigger. High-quality protein intake activates muscle repair through the mTOR signaling pathway, initiating satellite cell activation and structural reconstruction of muscle fibers damaged during prolonged eccentric load, especially during descent. Consuming approximately 50–60 grams of complete protein exceeds the anabolic threshold required to initiate tissue repair while minimizing prolonged catabolic exposure.
Sodium restoration is equally critical. Extended endurance effort results in significant sodium loss through sweat, which reduces plasma volume and impairs cardiovascular efficiency. Replenishing sodium restores circulatory stability, improves oxygen delivery, accelerates autonomic nervous system recovery, and stabilizes next-day heart rate variability patterns. This restoration directly improves recovery efficiency and physiological readiness.
Moderate carbohydrate intake restores essential glycogen reserves while preserving metabolic flexibility. Excessive carbohydrate intake can suppress fat oxidation pathways and prematurely shift the body back into glucose dependence. Controlled carbohydrate reintroduction allows continued mitochondrial repair while supporting structural recovery. This balance preserves the metabolic adaptations gained through fasted endurance exposure.
Observed TrailGenic physiological outcomes following this protocol included preserved ketone presence the following morning (2.4 ppm), stable cardiovascular recovery patterns, rapid muscle repair activation, and maintained mitochondrial metabolic efficiency.
Optimization can be further improved by reducing unnecessary carbohydrate load while preserving protein and sodium intake. Protein-style configurations improve metabolic signaling stability, reduce insulin response amplitude, and accelerate return to fat oxidation dominance. This preserves mitochondrial adaptation while enabling complete structural recovery.
The objective of TrailGenic refueling is not caloric replacement. It is restoration of metabolic stability, cellular repair capacity, and preservation of endurance adaptation.
