The rat isolated m. soleus perfused with bicarbonate buffer at 37 degrees C performed rhythmic work either with different loads and constant shortening or vice versa. The interrelationship between the work and the energy expenditure was the same in both cases. The energetic equivalence of strength and shortening at small loads in the skeletal muscle seems obvious as well as the absence of energy expenditure for shortening in the complete energetic cycle of muscle contraction, irrespective of the work. The energetic role of strength and shortening in the heart muscle is discussed.
在37摄氏度下用碳酸氢盐缓冲液灌注的大鼠离体比目鱼肌，能以不同负荷和恒定缩短率进行节律性工作，反之亦然。在这两种情况下，工作与能量消耗之间的相互关系是相同的。在骨骼肌中，小负荷下力量与缩短的能量等效性似乎很明显，而且在肌肉收缩的完整能量循环中，无论工作量如何，缩短过程都不存在能量消耗。文中还讨论了力量和缩短在心肌中的能量作用。
