Davis's law is a principle in human movement science that explains how soft tissue adapts structurally to the stresses placed upon it. NASM describes it as "soft tissue will model along the lines of stress," meaning that muscles, tendons, and fascia will align and reorganize based on the direction and type of physical forces they experience. This is important in corrective exercise because chronic poor posture, repetitive movements, or imbalances can cause soft tissue to remodel in a way that reinforces dysfunction. For example, if a muscle remains shortened for prolonged periods, collagen fibers may lay down in shortened patterns, limiting flexibility and altering joint mechanics. The other answer options describe different principles: poor neuromuscular efficiency (effect of chronic shortening), altered reciprocal inhibition (C), and the path of least resistance concept in movement compensation (D).
