Lasting Vigor describes a sustained, high-quality state of physical and mental energy, vitality, and functional strength that persists over a long duration, often throughout the later stages of life. This is not merely a transient feeling of energy but a deep-seated physiological capacity for sustained effort and engagement, reflecting robust mitochondrial health and endocrine vitality. The presence of lasting vigor is a clinical indicator of successful aging and healthspan extension.
Origin
The term “vigor” comes from the Latin vigere, meaning to be lively or flourish, and has long been used in a medical context to denote vital force and strength. The modifier “lasting” emphasizes the chronic, enduring nature of this optimal state, distinguishing it from temporary energetic boosts. It is a concept that aligns clinical longevity goals with subjective well-being.
Mechanism
The underlying mechanism for lasting vigor involves optimizing cellular energy production through efficient mitochondrial function and maintaining a favorable hormonal milieu, particularly stable levels of anabolic hormones like testosterone and DHEA. It also relies on the central nervous system’s capacity for sustained neurotransmitter production and reduced chronic stress, which prevents the depletion of adrenal reserves. This synergy ensures the continuous, efficient supply of physical and mental energy required for sustained high performance.
