Features of the recovery of the pumping function of the heart of athletes with disabilities after exercise

Objective: to study the reaction of heart rate and stroke volume of blood of athletes with disabilities to the implementation of standardized muscle load and the features of their recovery after completion of the load. Materials and methods: athletes are conditionally divided into two groups. The first group consists of wheelchair basketball players with amputated lower extremities. The second group consists of wheelchair basketball players with atrophy of the lower extremities. A comparative analysis of heart rate and stroke volume was carried out at rest, during muscle load and after its completion. Results: in athletes with disabilities with defects of the lower extremities, when performing a muscular load, heart rate increases by about two times compared with the initial parameters. Subsequently, heart rate values are significantly reduced. However, the rate of heart rate recovery within seven minutes of rest is not uniform. So, the most significant decrease in heart rate was observed in the second and third minutes of rest, where heart rate decreased by 17.9 and 20.1 beats/min, respectively (P
