Learn about the length-tension and force-length relationship and why they are important to skeletal muscle. Discover examples of the length-tension...
The total tension capability of a muscle is dependent upon its length. Active force generation is typically greatest at near-resting length while increased passive tension during lengthening...Prof. FrankChristoph MoorenSpringer Berlin HeidelbergEncyclopedia of Exercise Medicine in Health & Disease...
The present study examined the active and passive length-tension relationship of the abdominal expiratory muscles in vitro during electrically stimulated contractions. Studies were performed on isolated strips of transverse abdominis and external oblique muscle from nine adult hamsters with normal lung functi...
The length-tension relationships for arterial smooth muscle were determined using vascular strips teased from the media of hog carotid arteries. Histological examination revealed that the strips were (1) free of adventitia and (2) composed of smooth muscle cells oriented parallel to the long axis of...

Other things being equal, the stroke volume of the heart varies as the extent of diastolic filling, that is, the energy of contraction is a function of the initial length of the muscle fibers. Hellin's law See: Hellin's law Henry's law See: Henry's law Hilton's law See: Hilton, ...
Relationship between intracellular pH and tension development in resting ventricular muscle and myocytes Simultaneous measurements of intracellular pH (pHi) and tension development were made in resting cat papillary muscles and resting ventricular myocytes (ca...

where vmax > 0 is the maximum shortening velocity, Fim is the maximum isometric force, and F/Fim is the normalized muscle force. The parameter curv describes the curvature (Winters, 1990) of the force-velocity relationship, and results from the parameters a or b (− a and − b being...
Using Hill's equation, we calculated the values of P 0 (the maximum force at 1 0, lo being the trachealis muscle lenght at which the maximum active tension develops) and Vmax (the maximum veloxity at zero afterload). They were P 0 = 0.85 ± 0.20 kg/cm 2 and Vmax = 0.08 ± 0.02...
