Long-Term Functional Capacity

Meaning

Long-term functional capacity is the measure of an individual’s sustained ability to perform physical and cognitive tasks necessary for an independent, high-quality life over an extended lifespan. This metric integrates measures of physiological reserve, resilience, and the efficiency of metabolic and hormonal systems to resist age-related decline and chronic disease. Optimizing this capacity is the ultimate goal of longevity and healthspan protocols, ensuring vitality rather than merely survival. It quantifies the robustness of an individual’s biological hardware.
