研究人员测定了大鼠血浆中维生素A、锌和蛋白质的浓度以及肝脏中维生素A的水平，这些大鼠以跑步作为应激模型，分别接受标准饮食和不含维生素A的饮食。与不跑步的对照组动物相比，所有大鼠在跑步时血浆维生素a含量都有所下降。这两个试验组的肝脏维生素A水平高于体重和年龄相匹配的非跑步对照组。数据支持跑步，像其他形式的压力一样，减少血浆维生素A，这与维生素A在肝脏中的保留一致。
The plasma concentrations of vitamin A, zinc and proteins and the hepatic level of vitamin A were determined in rats subjected to running as a model for stress and which were receiving standard or vitamin-A free diets. All rats showed a decrease in plasma vitamin A with running compared with non-running control animals. Hepatic levels of vitamin A were higher in these two test groups than in their weight- and age-matched non-running controls. The data support that running, like other forms of stress, decreases plasma vitamin A, consistent with the retention of vitamin A in the liver.
