Frog sartorius muscle treated with 5.0 mM or greater caffeine exhibits stiffness similar to that obtained from muscle in iodoacetate rigor. The data provide quantitative evidence that suggests that caffeine at irreversible contracture-producing concentrations somehow induces a rigor or rigorlike state in skeletal muscle.

用5.0毫摩尔或更高浓度咖啡因处理的青蛙缝匠肌表现出的僵硬程度与碘乙酸盐致僵肌肉相似。这些数据提供了定量证据，表明在产生不可逆挛缩的浓度下，咖啡因以某种方式在骨骼肌中诱导出一种僵硬或类似僵硬的状态。
