最近，人们表达了这样的希望（Hill 1937，第116页），即随着一种更准确、更快速的肌肉热量测量技术的发展，可能会出现一幅更一致的肌肉缩短（或延长）和做正（或负）功的能量关系的图像。这个希望已经实现了，并且发现了一些非常简单和准确的关系，而且，这些关系（除其他外）决定了载荷对缩短速度的影响，允许预测等距收缩的形式，并且是骨骼肌所谓的“粘弹性”的基础。本文共分为三个部分。在第一部分中描述了该技术的进一步发展：一切都依赖于该技术，因此无需为相当充分的描述和必要的预防措施而道歉。第二部分对结果本身进行了描述和讨论。在第三部分中，活动肌肉的“粘弹性”特性被证明是第二部分中描述的特性的结果。
The hope was recently expressed (Hill 1937, p. 116) that with the development of a more accurate and rapid technique for muscle heat measurement, a much more consistent picture might emerge of the energy relations of muscles shortening (or lengthening) and doing positive (or negative) work. This hope has been realized, and some astonishingly simple and accurate relations have been found, relations, moreover, which (among other things) determine the effect of load on speed of shortening, allow the form of the isometric contraction to be predicted, and are the basis of the so-called “visco-elasticity” of skeletal muscle. This paper is divided into three parts. In Part I further developments of the technique are described: everything has depended on the technique, so no apology is needed for a rather full description of it and of the precautions necessary. In Part II the results themselves are described and discussed. In Part III the “visco-elastic” properties of active muscle are shown to be a consequence of the properties described in Part II.
