Some of the factors which influence the development of tension in cat tenuissimus muscle were studied quantitatively. Under isometric conditions, it was shown that the dynamic properties of the relationship between the tension of the muscle and its electrical stimulation depend on the mean rate of stimulation. This non-linear effect cannot be explained on the basis of the dependence of muscle tension on instantaneous rate of stimulation since the tension due to a stimulus following closely a previous stimulus is augmented, but the time course of the twitch response is unaltered. The interaction between the tension due to active contraction and that due to the viscoelastic properties of the muscle was investigated by independently varying muscle length and the rate of stimulation. Within the limits of resolution of the data, it was concluded that these two components of tension are addictive and that muscle stiffness is related to the instantaneous tension of the muscle.
对一些影响猫薄肌张力发展的因素进行了定量研究。在等长条件下，研究表明肌肉张力与其电刺激之间关系的动态特性取决于平均刺激频率。这种非线性效应无法基于肌肉张力对瞬时刺激频率的依赖性来解释，因为紧接着前一个刺激之后的刺激所产生的张力会增强，但抽搐反应的时间进程并未改变。通过独立改变肌肉长度和刺激频率，研究了主动收缩产生的张力与肌肉粘弹性产生的张力之间的相互作用。在数据分辨率的范围内，得出的结论是，这两种张力成分是相加的，并且肌肉僵硬度与肌肉的瞬时张力有关。
