Peculiarities of regulation of heart rhythm at the different stages of the academic process in students-athletes

Studied the mechanisms of heart regulation in untrained students and athletes. Cardiointervalograms were recorded during the training sessions and during the exams. The parameters of heart rate variability were analyzed by R.M. Bayevsky. The results showed that in all subjects there was a certain degree of activity increase in the central mechanisms of heart rhythm regulation, especially during the exams. In athletes, the degree of activity of parasympathetic influences was higher than that of untrained students at all stages of the survey. It is concluded that a certain degree of activation of sympathetic influences on the heart is necessary for successful adaptation, but in order to eliminate the risk of functional overstrain of the heart, it is necessary to introduce health technologies into the educational process.
