Creatine kinaza as transient muscular damage indicator: Analyzes and importance for technology of sports training

Previous research suggests that there is no single marker that would be sufficiently reliable indicator of muscle damage and overtraining. Monitoring several physiological indicators can lead to the desired response. Among them is the creatine kinase serum as one of the best indicators of muscle damage accompanying physical activity. In addition to other properties, it is a direct indicator of muscle damage and overtraining. The aim of this paper is the organization of knowledge published in relevant scientific journals that directly concern creatine kinase and its relation with other markers, as well as the limit of its use. By measuring the level of creatine kinase before and after exercise, the existence of myopathy without muscle biopsy can be predetermined, which is one of the most important functions of this serum. In the future, research should include other factors that indicate muscle damage and overtraining, their synergistic activity, and new findings in assessing transient muscle damage due to physical activity.
