Objective of the study was to evaluate the effectiveness of the training process of weightlifters using biochemical markers.
Methods and structure of the study.
The experiment involved elite weightlifters (men, women) consisting of 20 people (n=20), who were members of the national team of Kazakhstan. The study of biochemical parameters in the blood of creatinine, the activity of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), creatine phosphokinase (CPK) was carried out on an automatic biochemical express analyzer SpotchemSP-4430 (Japan).
Results and conclusions. The obtained results of the study indicate that athletes specializing in weightlifting are characterized by high values of metabolic biomarkers, such as CPK and creatinine. High levels of CPK and the index of muscle tissue damage negatively affect the effectiveness of the training process of weightlifters and can be used as informative indicators for correcting the training load.

Keywords: elite weightlifters, creatine phosphate mechanism of energy supply, creatinine, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), creatine phosphokinase (CPK), muscle damage index, de Ritis coefficient, training load, growth rates of sports and technical indicators.
