对储存在冰中的沙丁鱼进行尸检变化。快速（“白色”）肌肉磷酸肌酸在死亡后立即从 25 μmol/g 开始下降。 ATP浓度保持在约10μmol/g，并在观察到尸僵发作2小时后开始下降。当磷酸肌酸浓度达到与 ATP 相似的水平时 ATP 迅速下降，并在观察到完全严酷时 8 小时后为 2 μmol/g。乳酸积累与 ATP 降解（相关系数 r = -0.995）和尸僵程度（r = -0.989）平行进行。相比之下，沙丁鱼慢肌的磷酸肌酸（1μmol/g）和ATP（5μmol/g）含量较低，两者在死后立即下降。与快肌相比，该肌肉中的乳酸积累较低，与尸僵进展的相关性较低（r = -0.902）。
Postmortem changes were followed in sardines stored in ice. Fast (“white”) muscle creatine phosphate began decreasing from 25 μmol/ g immediately after death. ATP concentration remained about 10 μmol/ g and began decreasing after 2 hr when rigor mortis onset was observed. ATP decreased rapidly when creatine phosphate concentration reached a level similar to ATP, and was 2 μmol/g after 8 hr when full rigor was observed. Lactate accumulation proceeded parallel to ATP degradation (correlation coefficient r = -0.995) and the degree of rigor mortis (r = -0.989). In contrast, sardine slow muscle was low in creatine phosphate (1 μmol/g) and ATP (5 μmol/g), both of which decreased immediately after death. Lactate accumulation was low in this muscle and correlation with rigor mortis progress was lower (r = -0.902) than for fast muscle.
