J Neurophysiol. 1976 Jul;39(4):788-93. doi: 10.1152/jn.1976.39.4.788.

The properties of human soleus muscle were studied by systems analysis. Single stimulus pulses and random stimulus pulse trains were applied to a branch of the nerve to soleus muscle and the resultant tension fluctuations were recorded. 2. The frequency-response function between stimulus pulses and tension conforms to that of a second-order, low-pass filter. The parameters of the second-order system, low frequency gain, natural frequency, and damping ratio, varied systematically with the angle of the ankle. As the ankle was flexed (the length of the muscle was increased), the low frequency gain increased, the natural frequency decreased, and the damping ratio was unaffected or increased slightly. 3. These results are discussed in relation to the twitch responses of human soleus muscles and the responses previously observed in cat muscles.

通过系统分析研究了人类比目鱼肌的特性。将单个刺激脉冲和随机刺激脉冲序列施加于比目鱼肌神经分支上，并记录由此产生的张力波动。2. 刺激脉冲与张力之间的频率响应函数符合二阶低通滤波器的函数。二阶系统的参数，即低频增益、固有频率和阻尼比，随踝关节角度而系统变化。当踝关节屈曲时（肌肉长度增加），低频增益增加，固有频率降低，阻尼比未受影响或略有增加。3. 结合人类比目鱼肌的抽搐反应以及先前在猫肌肉中观察到的反应对这些结果进行了讨论。
