The aim of this study was to calculate the theoretical variation of the non linear damping factor (B) as a function of the muscle shortening velocity. The theoretical variation of the B factor was determined from a muscle model which consists of a contractile component in parallel with a viscous damper both in series with an elastic component, and by using the characteristic equation of the force-velocity curve. In this muscle model, the viscous element modeled the inability of the muscle to generate as a big contracting force (while shortening) as possible under isometric conditions. The results show that the theoretical behaviour of the B factor was dependent on the shortening velocity and on the af parameter which varies according to the muscle fibre type composition and affects the curvature of the force-velocity curve.
本研究的目的是计算非线性阻尼因子（B）随肌肉缩短速度变化的理论值。B因子的理论变化是通过一个肌肉模型确定的，该模型由一个收缩成分与一个粘性阻尼器并联组成，二者均与一个弹性成分串联，并利用力-速度曲线的特征方程。在这个肌肉模型中，粘性元件模拟了肌肉在等长条件下无法产生尽可能大的收缩力（在缩短时）的情况。结果表明，B因子的理论行为取决于缩短速度和af参数，af参数根据肌肉纤维类型组成而变化，并影响力-速度曲线的曲率。
