通过观察各种等张负荷下的缩短速度的简单装置，可以研究被剥夺参与任何非粘性组分的肌肉的机械特性。摘录。蛙缝匠肌和猫缝匠肌的研究表明，肌肉缩短的速度与肌肉在张力充分发展后释放的速度相同。随着缩短速度的增加，力减小，但以指数方式，而不是线性方式。这与产生额外能量以作缩短功的过程有关。肌肉不能被看作是一个简单的机械系统。
It is possible to study the mechanical properties of a muscle deprived of participation in any non-viscous component by the simple device of observing the speed of shortening under various isotonic loads. Expts. on the sartorius of Rana pipiens, and the sartorius of cats, show that the speed of shortening is the same as for a muscle released after tension is fully developed. As the speed of shortening increases, the force decreases, but in exponential, not linear fashion. This is concerned with the processes of developing extra energy for the work of shortening. A muscle cannot be treated as a simple mechanical system.
