描述了一种改进测定哺乳动物肌肉系列弹性组分顺应性的Wilkie快速释放技术的方法。这种修改消除了肌肉和杠杆系统质量的影响，增加了一个与收缩成分缩短有关的额外因素。大鼠反股薄肌串联弹性成分的顺应性从最大等距张力时的1.1 × 10-6 cm/达因到零张力时的17.6 × 10-6 cm/达因不等。在最大等距张力下，该部件的延伸长度为0.07。通过能量平衡技术计算出串联弹性组件的阻尼通常为300达因/厘米每秒。本研究的结果与其他横纹肌的结果进行了比较。
A method of modifying the Wilkie quick-release technique of determining the compliance of the series elastic component of mammalian muscle is described. This modification eliminates the effect of muscle and lever system mass by adding an additional factor related to the shortening of the contractile component. The compliance of the series elastic component of the rat gracilis anticus muscle varies from 1.1 x 10-6 cm/dyne at maximum isometric tetanic tension to 17.6 x 10-6 cm/dyne at zero tension. The extension of this component was 0.07 rest length at maximum isometric tetanic tension. The damping of the series elastic component was calculated from an energy balance technique to be typically 300 dyne/cm per sec. The results of this study are compared with those obtained from other striated muscles.
