The quantitative relationship between soleus muscle length and the angle of the ankle joint was studied in human cadaver lower limbs of various lengths. The ratio of soleus length to fibula length (lsol/lfib) was linearly related to ankle angle phi A. An expression for soleus resting length lr was derived from the parameters of this relationship and lr was estimated to be 0.998 lfib (S.E. of estimate = 0.004, P less than 0.0001). This gave a mean (+/- S.D.) value of lr of 361.4 (+/- 16.9) mm. The fractional change of lsol produced by rotation of the ankle joint was 0.004 lr.deg-1. The results of these analyses are used to predict lsol changes in intact subjects under varying experimental conditions.
在不同长度的人体尸体下肢中研究了比目鱼肌长度与踝关节角度之间的定量关系。比目鱼肌长度与腓骨长度之比（lsol/lfib）与踝关节角度phi A呈线性相关。根据该关系的参数推导出比目鱼肌静息长度lr的表达式，估计lr为0.998 lfib（估计标准误 = 0.004，P < 0.0001）。这得出lr的平均值（±标准差）为361.4（±16.9）mm。踝关节旋转产生的lsol的分数变化为0.004 lr·deg-1。这些分析结果用于预测在不同实验条件下完整受试者中lsol的变化。
