钙激活力的发展在去皮青蛙肌纤维被抑制的纤维压缩，可能是由于肌丝之间的间距减少。这种抑制取决于肌节长度，因为长长度的纤维必须比短长度的纤维压缩得更深，以达到相同的抑制程度。因此，这种长度依赖性的抑制倾向于补偿力的减少，这仅仅是由于在完整纤维中拉伸时发生的丝间间距的减少。
Calcium-activated force development in skinned frog muscle fibers is inhibited by osmotically compressing the fiber, probably owing to a decrease in spacing between the myofilaments. This inhibition depends upon sarcomere length in that fibers at long lengths must be compressed further than those at short lengths to achieve the same degree of inhibition. As a result, this length dependency of inhibition tends to compensate for the reduction of force due solely to the decrease in interfilament spacing which occurs with stretch in intact fibers.
