Abstract

It has been analyzed in the article the change of spectral parameters of heart rate variability of the students of various disciplines influenced by conditions of educational and practical activities. It has been established that during training for women of all groups the studied parameters were reduced, and the students of «Physical culture» value LF increased almost in 2 times (P≤0,05) in parallel with a decrease of VLF (of 902 [497; 1417] to 516 [401; 723] square milliseconds P≤0,05). During the internship in students of «Foreign Languages» significantly increased rate of vegetative balance LF/HF (from 1,47 [0,88; 1,80] to 1,63 [1,18; 3,15] standard units, P≤ 0.05) and all the studied parameters tended to increase (P≥0,05). The growth of total power of spectrum (1969 [1298, 2398] to 3273 [1874; 4568] square milliseconds P≤0,05) in women specialty «Chemistry and Biology» testified to the increased activity of independent regulation circuit. In the students’ «Physics and Mathematics» and «Physical Education» downward trend indicators had HF, VLF, TP and to increase – LF and LF / HF (P≥0,05). Changes of spectral indices point to strengthen sympathykotonic impacts and reduction of adaptive capacity in women «Physical Education» experiencing psycho-emotional tension combined with mental and physical load.

Keywords: heart variability rate, spectral indexes, vegetative nervous system, sympathetic and parasympathetic links of regulation, students of pedagogical higher educational establishment
