An experimental method is described for estimating the mechanical properties of human soft tissues by calculating Young's modulus which was defined according to the slope of the hysteresis curve of the test subject, reflecting the dependence of its deformation on the force applied. The main causes of numerous difficulties in obtaining such data and the ways for their overcoming are considered. Experiments were made on the biceps in the isometric mode under different degrees of internal tension. It has been shown that the higher the physical development of the test subject the less the magnitude of Young's modulus. The dependence of its magnitude on the degree of muscular tension is sublinear in character in the group with good physical development and superlinear in that with poor physical development.
本文描述了一种实验方法，通过计算杨氏模量来估计人体软组织的力学性能，该模量根据测试对象滞后曲线的斜率定义，反映其变形与所施加力的依赖关系。文中考虑了获取此类数据时诸多困难的主要原因及其克服方法。在等长模式下，对处于不同内张力程度的肱二头肌进行了实验。结果表明，测试对象的身体发育程度越高，杨氏模量的值越小。在身体发育良好的组中，其值与肌肉张力程度的关系呈亚线性，而在身体发育较差的组中则呈超线性。
