Objective of the study was to find a correlation between the physiological and biochemical indicators affected by the composition of royal jelly and Q10 and effectiveness of functional test execution by highly qualified athletes. Methods and structure of the study. The study involved 40 highly qualified male swimmers aged 16 to 20 years. As a control exercise we used a series of segments 4x50 m covered using the main stroke with 45 sec of rest breaks in between. Based on the pretest results, we formed 2 groups of subjects with similar morphofunctional indicators. In the CG, the athletes were given honey (placebo) daily at a dose of 10 g/day for 10 days. In the EG, during the same period, the subjects were given the composition as follows: honey + royal jelly + Q10 at a dose of 10 g/day, including 400 mg/day of royal jelly and 60 mg/day of Q10. Results of the study. We detected the regression relations showing that the composition of royal jelly and exogenous ubiquinone-10 (Q10), when administered for 10 days, statistically significantly affected the dynamics of changes in a number of physiological and biochemical indicators in the highly qualified swimmers during the control tests. Conclusion. Using the principal component method and correlation analysis, it was shown that the co-use of royal jelly and Q10 improves the effectiveness of execution of the control exercise through the correction of the athletes` heart rate variability rates, inhibition of lipid peroxidation processes, and suppression of the development of hyperlactatemia under physical loads.
