Аннотация:Aim. The article is aimed at studying the relationship between the neurodynamic characteristics of athletes of different sports and the indicators of physical fitness obtained during exercise tests. Materials and methods. The study involved male athletes aged 16–21 years, involved in swimming (20 people) and powerlifting (16 people), having sports ranks from the 2nd adult to a candidate for master of sports. The volume and concentration of attention, the speed of eye-hand coordination, the level of functional mobility, the strength of nervous processes, the response to a moving object and the tapping test were processed using an automated program. Indicators of aerobic and speed - strength fitness of the muscles of the lower extremities were determined by the cycle ergo meter tests. Results. Swimmers differed from power lifters by a smaller volume, but better concentration of attention, higher dynamism and strength of nervous processes, less pronounced excitement in the central nervous system, high rates of aerobic energy supply and a less pronounced correlation between the functional indicators and psychophysiological characteristics. In both groups, negative correlations of aerobic performance with the speed of visual motor responses and positive correlations with the balance of nervous processes were revealed. Speed-strength indicators are better for athletes with a high functional mobility, dynamism and strength of nervous processes. Conclusion. There is a correlation between the neurodynamic characteristics and indicators of functional fitness, which must be taken into account when interpreting the results of stress tests and developing individual recommendations based on the results of the examination.
