NMR spectroscopy was used to study carnosine and anserine metabolism in rat tissues under intensive muscle loading. Muscle loading was accompanied by the dipeptide (predominantly anserine) accumulation in muscle tissues. Preliminary per os administration of carnosine (250 mg/kg of body mass) did not increase the dipeptide content in muscle tissues but diminished the lactate content in rat muscles under intensive muscle loading.
采用核磁共振光谱法研究了高强度肌肉负荷下大鼠组织中肌肽和鹅肌肽的代谢情况。肌肉负荷伴随着二肽（主要是鹅肌肽）在肌肉组织中的积累。预先经口给予肌肽（250毫克/千克体重）并没有增加肌肉组织中二肽的含量，但在高强度肌肉负荷下降低了大鼠肌肉中乳酸的含量。
