What is the Origin of Age-Related Performance Deficit?

The term derives from the intersection of gerontology and performance physiology, acknowledging that functional decline is not merely inevitable but a quantifiable clinical entity. It frames aging as a progressive loss of physiological reserve capacity, moving the focus from disease pathology to measurable functional limitation. This concept is foundational to preventative medicine and advanced longevity science.

What is the Mechanism of Age-Related Performance Deficit?

The deficit is primarily driven by age-related hormonal changes, such as somatopause and andropause/menopause, alongside increasing systemic inflammation. These endocrine shifts impair anabolic processes and accelerate sarcopenia, while mitochondrial dysfunction reduces ATP production. The net result is a decline in physiological efficiency across multiple organ systems, leading to the measurable reduction in performance physiology standards.

Age-Related Performance Deficit

Meaning

Age-Related Performance Deficit is a measurable decline in physical, cognitive, and metabolic capacity that correlates directly with the chronological aging process. This deficit manifests clinically as reduced muscle mass, decreased aerobic capacity, diminished hormonal output, and slower neurocognitive processing speed. It represents the cumulative functional impairment resulting from cellular senescence and compromised systemic homeostasis. Addressing this deficit is central to health span extension.
