What is the Origin of Muscle Preservation Agents?

This term is a clinical nomenclature arising from sports medicine and geriatrics, reflecting the growing understanding of muscle mass as a vital biomarker for overall healthspan and mortality risk. The "Preservation" focus underscores the primary therapeutic goal of preventing muscle catabolism and promoting anabolism, especially in the context of hormonal shifts or chronic illness. It emphasizes the importance of skeletal muscle as an endocrine organ.

What is the Mechanism of Muscle Preservation Agents?

These agents operate by enhancing the anabolic signaling pathways within muscle cells, primarily through the activation of the mTOR pathway and by increasing insulin-like growth factor 1 (IGF-1) expression. Many also function by selectively binding to androgen receptors in muscle tissue, promoting protein synthesis and hypertrophy while minimizing off-target effects on other organs. The core mechanism is shifting the net protein balance in the muscle cell toward anabolism.

Muscle Preservation Agents

Meaning

Muscle Preservation Agents are a class of therapeutic compounds, encompassing specific amino acids, selective androgen receptor modulators (SARMs), and certain peptides, utilized clinically to maintain or increase lean muscle mass and prevent sarcopenia. These agents are critical in longevity medicine to counteract the age-related decline in muscle protein synthesis and mitigate the associated loss of strength and metabolic health. Their application is targeted toward sustaining functional independence.
