Creatine lysinate – part II: effects on the motor coordination and muscle hypertrophy in mice.

In the current study, we investigated the effect of creatine monohydrate (CrM) and newly synthesized creatine lysinate (CrLys) in tail suspension (TST) and rotarod tests and their influence on the histology of the skeletal muscles. In the TST, a slight decrease in the immobility time from the 1^st to the 3^rd week was observed in the group treated with CrM at a dose of 1.5 g/kg/day and CrLys at a dose of 6 g/kg/day. The rotarod test revealed that CrM (1.5 g/kg/day) and CrLys (3 g/kg/day) lead to a significant improvement in motor coordination in the 3^rd week. The results from histology showed an increase in the muscle fiber diameter of soleus muscle in animals treated with CrM (3 g/kg/day) and CrLys (6 g/kg/day). The results showed that supplementation with creatine derivatives appears to be a generally effective nutritional ergogenic aid for an improvement of physical performance. [ABSTRACT FROM AUTHOR]
