Sustained Human Power

Meaning

Sustained Human Power refers to the physiological capacity to maintain high levels of physical and cognitive output over extended periods without incurring excessive allostatic load or a precipitous decline in performance. This critical capacity is fundamentally underpinned by robust mitochondrial function, efficient metabolic fuel switching, and the precise, coordinated action of the major endocrine axes. It is a key metric for systemic resilience, metabolic flexibility, and the overall functional reserve of the healthspan. This capability differentiates acute effort from true long-term vitality.
