Mechanical Tension Signaling

Meaning

Mechanical Tension Signaling refers to the highly sophisticated cellular process by which physical forces, such as tension, compression, and shear stress, are detected by cells and subsequently converted into specific biochemical and genetic responses. This mechanotransduction pathway is a primary and essential driver of tissue adaptation, fundamentally dictating processes like skeletal muscle hypertrophy and the accrual of bone mineral density. The precise quality and magnitude of this signaling are directly correlated with the health, strength, and structural integrity of the entire musculoskeletal system. Optimizing this mechanical signal through resistance exercise is a core strategy for maintaining physical function across the lifespan.
