Why Mechanical Tension Is the Primary Driver of Muscle Hypertrophy: The Cellular Evidence
What Drives Muscle Hypertrophy? Mechanical tension is the foundational physiological trigger for skeletal muscle hypertrophy. When high-threshold motor units are recruited and muscle fibers produce active force at slow contraction velocities, cellular mechanosensors transduce mechanical strain into intracellular biochemical cascades, primarily activating the mTORC1 pathway to stimulate muscle protein synthesis (Lim et al., 2022; Wackerhage…
