Abstract: The smallest contractile unit in striated muscles is the sarcomere. While some of the classic features of contraction assume a uniform behavior of sarcomeres within myofibrils, the occurrence of sarcomere length non-uniformities has been well-recognized… read more here.

Abstract: Heart failure can reflect impaired contractile function at the myofilament level. In healthy hearts, myofilaments become more sensitive to Ca2+ as cells are stretched. This represents a fundamental property of the myocardium that contributes to… read more here.

DOI: 10.3389/fphys.2023.1242177
Abstract: Sarcomere lengths are non-uniform on all structural levels of mammalian skeletal muscle. These non-uniformities have been associated with a variety of mechanical properties, including residual force enhancement and depression, creep, increased force capacity, and extension… read more here.
