Somatic Tissue Accretion

Meaning

This refers to the physiological process of increasing the net mass of non-reproductive, structural body tissues, most notably skeletal muscle, bone, and connective tissue. It represents a state of positive anabolic balance where the rate of tissue synthesis and deposition exceeds the rate of catabolic breakdown. Optimizing somatic tissue accretion is critical for maintaining strength, mobility, and metabolic reserve throughout the aging process. This process is essential for countering age-related frailty.
