... (force enhancement) and decreases after active shortening (force depression). In addition to cross-bridges, titin has been suggested to contribute to force enhancement and depression. Although titin is too compliant in passive muscles to contribute to active tension at short sarcomere lengths...

...Shawn M. O'Connor; Elton J. Cheng; Kevin W. Young; Samuel R. Ward; Richard L. Lieber ABSTRACT Laser diffraction (LD) is a valuable tool for measuring sarcomere length (L s), a major determinant of muscle function. However, this method relies on few measurements per sample that are often...

... in sarcomere length per degree joint angle rotation (i.e. d SL /dω) was measured as the wrist was moved from neutral to full flexion in both the extensor carpi radialis brevis (ECRB) and extensor carpi radialis longus (ECRL) muscles. Sarcomere length change per degree rotation was approximately twice as great...

...Rob S. James; Iain S. Young; John D. Altringham ABSTRACT The errors likely to result from using excised rigor muscles to determine in vivo sarcomere length ranges were calculated for mouse extensor digitorum longus muscle (EDL). This muscle was chosen because its very long tendon makes...

... frequency ranges just below, or at, those yielding maximal power. Soleus and EDL produced maximal power output in vitro when operating at mean sarcomere lengths of 2.58 μ m and 2.71 μ m respectively. These lengths are slightly above the plateau of the length–force curve predicted for rat leg muscle (2.3–2.5...

...Lawrence C. Rome; Roel P. Funke; R. Mcneill Alexander ABSTRACT The aim of this study was to evaluate how fish locomote at different muscle temperatures. Sarcomere length excursion and muscle shortening velocity, V, were determined from high-speed motion pictures of carp, Cyprinus carpio (11–14cm...
