Force-length relationship 非本书图片 肌节能够产生的最大力量会随着肌节长度的变化而变化。长度与张力之间的关系可以通过滑动丝线理论(sliding filament theory)来解释,该理论于1954年由两个研究团队独立提出。Andrew Huxley和Rolf Niedergerke(在单个肌肉纤维中)以及Hugh Huxley和Jean Hanson(在分离的肌原纤维中)展示了...

The observation that the length-force relationship in airway smooth muscle can be shifted along the length axis by accommodating the muscle at different lengths has stimulated great interest. In light of the recent understanding of the dynamic nature of length-force relationship, many of our concepts...
Relationship between deformation and force. The normalized mean deformation area under the curve for each subject is plotted against the percent of maximal voluntary contraction (%MVC). (a) A linear relationship is observed for all five neck muscles summed in some individuals (n = 11; R2...
length during stance to half-sarcomere length, assuming an optimal sarcomere length during maximal activation of 2.6 µm at the short side of the plateau region of the sarcomere force–length relationship58. The number of crossbridge cycles was estimated from the amount of shortening within each...

AUC = area under the force–power curve; a.u. = arbitrary units. * indicates a significant difference (p≤ 0.05) from the Female group. 3.4. Correlations between Variables Significant correlations were detected between 30 m sprint time and VLcEI (r = 0.76; p≤ 0.001 in both male and...
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. ...
BACKGROUND AND PURPOSE: The purpose of this study was to determine the level of muscle force associated with ability to walk in the community without assistance, in the community with assistance, or at home only in individuals with amyotrophic lateral sclerosis (ALS). SUBJECTS AND METHODS: Percen...
Force-length relation for tetanic contractions (n = 10). The theoretical (thick line) relationship is obtained from ter Keurs et al. (1984) with a plateau extended from 2.26 μm to 2.43 μm and a zero overlap intercept on the descending limb occurring at 3.79 μm. The DT is given rel...
