Individual Features of Vegetative Support for Student-Athletes of Various Specializations

The aim of this paper is assessment of the features of vegetative support of the body of students of various sports specialization. Results: Significant differences in statistical and spectral HRV indicators in volleyball and swimming groups have been established. The volleyball players had lower SDNN, RMSSD, total spectrum power, as well as a higher level of the pNN50 parameter and heart rate. They have a tendency to increase the centralization of the heart rhythm and activation of sympathetic regulation. These assumptions confirm the values of the spectral analysis of cardiac rhythm, which shows the initial stage of overtraining and overwork in the volleyball group. To prevent maladaptation conditions, it is advisable to correct the training process in a group of students engaged in volleyball. Conclusion: In volleyball athletes, an increase in the activation of central regulatory mechanisms has been demonstrated, which leads to impaired functioning of adaptive and regulatory mechanisms, as well as to the initial stage of overtraining. To prevent this, it is advisable to adjust the training process in the volleyball group.
