青蛙骨骼肌肌浆中游离钙的浓度因拉伸而增加。游离钙的上升幅度随着拉伸程度和环境温度的升高而增加，咖啡因则增强了这种上升。这种现象可能在牵张引起的肌颤增强和代谢率增加中起作用。
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.
