Features of changes in the parameters of the pumping function of the heart in school-age children engaged in sports acrobatics

In the study, it can be summed up that in young athletes systematically engaged in sports acrobatics, the heart rate response to performing a low-power muscle load does not change as the level of fitness increases. Also, after performing a low-power muscle load, the heart rate of young acrobats, regardless of the level of fitness, is restored by the end of the first minute of rest. It was found that in young acrobats, regardless of the level of training, the shock volume of blood when performing a low-power muscle load increases by about 20-25 ml compared to the initial data. It was revealed that as the level of training in acrobats increases, the reaction of the shock volume of blood to the performance of standardized muscle load does not change significantly.
