Physical Strength Retention

Meaning

Physical Strength Retention is the crucial capacity to maintain optimal muscle mass, contractile force generation, and stable bone mineral density over time, a process primarily governed by the anabolic influence of growth hormone and testosterone signaling pathways. This is a direct, functional readout of the body’s intrinsic ability to counteract age-related sarcopenia and maintain structural integrity across the lifespan. Clinical assessment in this area focuses intensely on preserving lean body mass index metrics.
