Objective of the study was to analyze creatinine rates in elite weightlifters and identify the nature and degree of their relationship with the level of sport-specific technical mastery. Methods and structure of the study. The experiment involved 11 elite weightlifters, members of the national team of the Republic of Kazakhstan. The biochemical control was carried out 4 weeks before the World Cup or Asian Championship. Results and conclusions. The study found a statistically significant relationship between a sports result, being expressed in points and representing an absolute sports result per unit of own body weight, and creatinine rate per kg of own body weight r=0.78 (p<0.01). The mean group result in the double-event, expressed in points (the Sinclair table), was M=395.4; S=20.0. The mean group creatinine rate was M=144.8 μmol/L; S=11.8. The mean group creatinine rate per kg of own body weight was M=1.82 μmol/L per kg of body weight; S=0.5. The study showed that creatinine as a biochemical marker can be an informative indicator for evaluating the effectiveness of athletic training under such a criterion as the special orientation of training loads on the development of creatine phosphate mechanism of energy supply to the contracting muscles when performing exercises with the maximum effort.
