Performance Erosion is the measurable, progressive decline in physical and cognitive output metrics over time, characterized by reduced strength, decreased endurance, slower processing speed, and diminished recovery capacity. This phenomenon is a direct clinical manifestation of age-related physiological decline and chronic, low-grade catabolic stress. It represents the functional consequence of hormonal and cellular aging.
Origin
This is a descriptive term utilized in sports medicine and longevity science to characterize the inevitable decline in functional reserve that occurs with advancing age. The term “erosion” highlights the gradual, detrimental nature of this biological process.
Mechanism
The underlying mechanism involves a confluence of factors, including age-related reductions in anabolic hormones like Growth Hormone and DHEA, chronic low-grade inflammation, and the accumulation of cellular damage (senescence). These elements collectively impair mitochondrial function, reduce muscle protein synthesis, and diminish neuroplasticity, leading to a systemic loss of reserve capacity.
