Abstract
The concentration of free calcium in the sarcoplasm of a resting frog skeletal muscle is increased by stretch. The magnitude of the rise in free calcium increased with the degree of stretch and the ambient temperature and it was enhanced by caffeine. This phenomenon might play a role in the twitch potentiation and enhanced metabolic rate evoked by stretch.
摘要
静息状态下的青蛙骨骼肌肌浆中游离钙的浓度会因拉伸而升高。游离钙升高的幅度随拉伸程度、环境温度的增加而增加，且咖啡因可增强这种升高。这种现象可能在拉伸引起的抽搐增强和代谢率提高中发挥作用。
