Abstract: The stories of change and functionality of the first-year students’ cardiovascular system at the beginning (1st stage) and the end (2nd stage) of the school year by parameters of hemodynamics and heart rate variability (HRV) were investigated. based on this investigation it is revealed that from the beginning to the end of the school year the disadaptation of the cardiovascular system by parameters of central hemodynamics and HRV increases in most of the students. Under relative rest circumstances, students’ heart rate, systolic and diastolic blood pressure (SBP and DBP) at the 2nd stage increased (p< 0.05) in comparison to age norms and their values identified at the 1st stage. At the 2nd stage, adaptive potential (AP) values indicated expressed diastolic myocardial stress. At the 1st stage, the average level of exercise and mechanical production was reported in students by average values of Robinson index (RI). The 2nd stage showed a reduction in aerobic support of the myocardium and its adaptive capabilities. According to the adaptive capacity (AC) average values, students at both stages were under adaptation breakdown conditions. At both stages, the students demonstrated normotony according to R-R and heart rate parameters with an increase of parasympathetic effects on the HR modulation at the 2nd stage. 58% and 66% of the first-year students, according to individual values of TI at the 1st and 2nd stages respectively, revealed poor adaptation, 29%, and 25% of them showed the state of adaptation failure, the rest of them demonstrated satisfactory adjustment.
Keyword: hemodynamic parameters, endurance and efficiency of the circulatory system, the type of self-regulation, the type of autonomous regulation of the heart rate.
