Mechanical properties of muscle

WebMay 16, 2024 · The most important properties influencing a muscle’s passive viscoelastic behavior are the maximum elongation capacity (maximum stretch), stiffness or modulus (resistance to deformation), hysteresis (energy loss before restitution), and stress-relaxation and creep (i.e., a time-dependent reorganization of the tissue resulting in a loss of force … WebSkeletal muscle is made up of long fibres, terminated at each end by tendinous material attached to the bone. These fibres are formed from a syncitium of cells whose walls fuse during development, and hence have many nuclei spread throughout their length. Groups … Mechanical Properties of Muscles. John C.
