... at the same muscle length and level of activation, are referred to as residual force enhancement (rFE) and residual force depression (rFD), respectively. The purpose of these experiments was to investigate the trainability of rFE and rFD on the basis of serial sarcomere number (SSN) alterations to history...

... contraction in which fibres were activated and then shortened from an average sarcomere length of 3.3 μm to 3.0 μm. The second test was a SSC in which fibres were activated and stretched from 3.0 μm to 3.3 μm, and then shortened to 3.0 μm. The third test was a SSC in which fibres were activated and stretched...

...Michael M. DuVall; Azim Jinha; Gudrun Schappacher-Tilp; Timothy R. Leonard; Walter Herzog ABSTRACT Since the 1950s, muscle contraction has been explained using a two-filament system in which actin and myosin exclusively dictate active force in muscle sarcomeres. Decades later, a third filament...

... as the sarcomeric cytoskeleton, is essential for the ordered assembly of actin and myosin filaments into sarcomeres, by combining architectural, mechanical and signalling functions. This review discusses recent cell biological, biophysical and structural insight into the regulated assembly of sarcomeric...

...Walter Herzog Muscle contraction and force regulation in skeletal muscle have been thought to occur exclusively through the relative sliding of and the interaction between the contractile filaments actin and myosin. While this two-filament sarcomere model has worked well in explaining...

...Thomas J. Burkholder; Richard L. Lieber ABSTRACT The force generated by skeletal muscle varies with sarcomere length and velocity. An understanding of the sarcomere length changes that occur during movement provides insights into the physiological importance of this relationship and may provide...

Electrocytes arise from the fusion of fully differentiated muscle fibers, mainly those expressing fast isoforms of myosin. Electrocytes briefly co-express sarcomeric...

... in other species. Sarcomere strains of axial muscle fibres were calculated at 0.4 and 0.8 FL . During C-starts, white muscle fibres were exposed to maximum sarcomere strains of up to approximately 16 %, and posterior fibres had similar strains to anterior fibres (red 27 %; white 16 %). During S-starts...
