What is the Origin of Age-Related Performance Attrition?

The concept is rooted in the convergence of gerontology and exercise physiology, combining the understanding of age-related biological processes with the quantifiable reduction in performance metrics. The term attrition emphasizes a gradual wearing down of functional capacity over time, directly linking measurable functional decline to the process of endocrine senescence. It serves as a clinical descriptor for the measurable decline associated with the aging neuroendocrine system.

What is the Mechanism of Age-Related Performance Attrition?

Attenuation is driven by molecular factors like telomere shortening, mitochondrial dysfunction, and critically, a systemic reduction in the pulsatile secretion of key anabolic hormones such as testosterone, growth hormone, and DHEA. The chronic, low-grade inflammatory state, often termed 'inflammaging,' also contributes significantly by impairing tissue repair and endocrine gland responsiveness. These molecular and hormonal shifts collectively diminish the body's homeostatic reserve and functional output over time.

Age-Related Performance Attrition

Meaning

The progressive, physiological decline in physical, cognitive, and metabolic function observed as an organism ages is clinically defined as Age-Related Performance Attrition. This systemic reduction in functional capacity is a natural consequence of biological aging, involving shifts in cellular efficiency and systemic endocrine signaling. Clinically, it manifests as diminished recovery, reduced capacity for exercise, and measurable changes in hormonal balance.
