HRV indicators in wheel-chair basketball players under the influence of training load

   Relevance The purpose of this study is to study the functional state and features of the regulation of cardiac activity of athletes with disabilities, with damage to the musculoskeletal system, engaged in wheel-chair basketball. For several years now, the number of athletes in this sport has increased.
The purpose of the study is to study the functional capabilities of athletes, which will not only reveal their potential and capabilities, but also identify specific needs that can be met with the help of appropriate training and rehabilitation.

   Methods and organization of research. Measurements of anthropometric parameters were carried out, conclusions were made on the indicators of pulse, blood pressure, oxygen saturation and heart rate variability. As part of a step-by-step study of the functional state of athletes in the preparatory period of a oneyear training cycle, the level of adaptation of athletes was assessed using cardiointervalometry. As a result of the research, it was concluded that according to the spectral analysis of heart rate variability, the initial state of the autonomic nervous system of the studied group of athletes with musculoskeletal system damage engaged in wheelchair basketball was characterized by simatonia at rest, high pulse, systolic and diastolic, as well as pulse pressure were recorded. It was found that the level of activation of the vasomotor center of regulation has the strongest reliable influence on changes in the pulse as an indicator of adaptive potential.

   Conclusions. It was revealed that the average values of CCC indicators in Paralympic basketball players differ significantly from those of ordinary athletes. In particular, Paralympic basketball players have high pulse rates, systolic and diastolic, as well as pulse pressure. While the frequency analysis indicators are within the low values.
