The use of biochemical indicators in the system of improving the control of training loads in canoeing

Relevance. In recent decades, the registration of a complex of biochemical parameters has become an integral component of the ongoing monitoring of highly qualified athletes. However, the results of monitoring these indicators do not always carry the necessary amount of information. The aim of the study is to determine the diagnostic significance of the traditional complex of biochemical parameters used in the system of routine monitoring of highly qualified canoe rowers. Methods. The observations were attended by 19 male canoe rowers of highly qualified, age from 21 to 33 years, of which 7 ZMS, 6 MSMC, 6 MS. The studies were conducted repeatedly for 3 years. Registered: the content of hemoglobin, urea, cortisol, total testosterone, hematocrit index, total cre-atine phosphokinase (CKF) activity at different post-loading intervals. The reliability of the differences between all the values of the analyzed indicators (uncorrected sample) and after preliminary exclusion from the analyzed samples of the values of indicators that significantly differ from the majority (the so-called "potential statistical outliers") was calculated. For this purpose, the "quartile range" was determined. Results. It is established that when analyzing individual samples of biochemical indicators, it is necessary to exclude statistical outliers. The markers whose values correspond most closely to the intervals of post-loading recovery that differ in duration include only the activity of the general CPK. The current changes in the content of urea, cortisol, testosterone and the recorded indicators of red blood are less informative in this regard. Conclusion. Only the activity of total creatine phosphokinase belongs to the biochemical markers, the values of which, in terms of their weekly dynamics, correspond most closely to the intervals of post-loading recovery that differ in duration.
