肌肽和牛磺酸含量的股外侧肌的两个不同群体的韩国男性受试者（老年人和受损的葡萄糖耐量（IGT）的主题和年轻的精英游泳运动员在国立体育大学）有一个类似的国家的饮食，进行了检查。尽管在年龄，健身和临床状态的显着差异，两组显示几乎相同的肌肉肌肽和牛磺酸含量。在肌肽的情况下，结果表明在两组受试者中对细胞内缓冲能力的贡献相似，没有证据表明在老年IGT受试者中这种缓冲能力降低。此外，两组显示出相同的肌肽和牛磺酸含量之间的反比关系;受试者之间，组内的值的传播，最有可能反映的变化，在I型（低肌肽，高牛磺酸）或II型（高肌肽，低牛磺酸）组成的股外侧肌。这种关系与牛磺酸在肌肽调节中的作用一致，补偿肌肽含量中纤维类型之间的变化。
The carnosine and taurine contents of the vastus lateralis of two diverse groups of Korean male subjects (elderly and impaired glucose-tolerant (IGT) subjects and young elite swimmers at a national sport university) having a similar national diet, were examined. Despite marked differences in age, fitness and clinical status the two groups showed almost identical muscle carnosine and taurine contents. In the case of carnosine, the results suggest a similar contribution to intracellular buffering capacity in the two groups of subjects, with no evidence of a reduction of this in elderly IGT subjects. In addition, both groups showed the same inverse relationship between the muscle carnosine and taurine contents; the spread of values between subjects, within-groups, most likely reflect variations in the type I (low carnosine, high taurine) or type II (high carnosine, low taurine) composition of the vastus lateralis. The relationship is consistent with a role of taurine in osmoregulation, compensating for variations between fibre types in the carnosine content.
