即使在不活跃的状态下,当肌肉被拉伸超过其静息长度时,也会产生力量,就像一个非线性弹簧一样。这种被动的力-长度关系(passive force-length relationship)主要源于肌肉中的两个结构:钛蛋白(titin)和围绕纤维、束和肌肉的结缔组织。钛蛋白是一种大型、灵活的蛋白质,它将厚丝锚定在肌节两端的Z线上。当肌节短时,钛蛋...

Definition The force-velocity relationship describes how muscle force depends upon the velocity of movement or vice versa . Characteristics Quantitative Description The seminal experiments of A.V. Hill showed that the velocity of shortening in actively contracting skeletal muscle depended upon the force ...
Research into defining a load-independent measure of contractility has been active. When the length of an isolated muscle strip is held constant, force and velocity are inversely correlated. In the intact heart, this relationship can be defined usingarterial pressureand echocardiographic parameters.Colan...
We conclude from these findings that passive, mean SLs obtained from a single location are not necessarily representative of the distribution of SL in active muscle, and thus may be misinterpreted when deriving muscle mechanical properties, such as the force-length relationship. In view of these ...
during stretching in several studies, and the relationship between shear modulus and passive muscle force during slow stretching has been shown to be linear. Studies based on musculoskeletal modeling[25,29]as well as works performed in vitro on chicken muscles[26,30]yielded the same results. ...
Muscle - Actin-Myosin, Regulation, Contraction: Mixtures of myosin and actin in test tubes are used to study the relationship between the ATP breakdown reaction and the interaction of myosin and actin. The ATPase reaction can be followed by measuring the
The contractile machinery of heart and skeletal muscles has as an essential component the thick filament, comprised of the molecular motor myosin. The thick filament is of a precisely controlled length, defining thereby the force level that muscles gener
The initial response of isometric contracting muscles to a short quick stretch and release is characterised by a linear relationship between changes in muscle force and length, referred to as short-range stiffness (Cui et al., 2008). Muscle stiffness is determined by a number of factors that ...
