What is the Origin of Functional Vigor?

The concept is widely used in anti-aging and functional medicine to describe the tangible outcome of successful health interventions, contrasting with the passive concept of simply being alive. "Functional" emphasizes the quality and efficiency of biological systems in action, while "vigor" denotes strength and energy. It is a metric of biological youthfulness and high vitality.

What is the Mechanism of Functional Vigor?

Functional vigor is underpinned by the harmonious operation of the neuroendocrine and musculoskeletal systems. Key mechanisms include maintaining optimal mitochondrial density and function for efficient ATP production, robust neurotransmitter balance for mood and cognition, and adequate anabolic hormone signaling for tissue repair and maintenance. A well-regulated HPA axis ensures effective stress response and recovery, all contributing to sustained high-level performance and well-being.
