Linear myofilament mechanics may update sarcomere models; leaves open validation in intact fibres and in vivo.
Massimo Reconditi (2010) conducted a letter in Skeletal muscle myofilament elasticity. Re-analysis of myofilament stiffness data was evaluated on Stress-strain relationship of myofilaments. Re-analysis of skeletal muscle fibre data demonstrates that when uncertainties and overlap region contributions are accounted for, myofilaments exhibit a linear stress-strain relationship.
