PROCEDURE AND THE ORGANIZATION OF RESEARCHES

116 experiments with participation in quality of examinees practically healthy for the researches, physically not trained men 19 - (N=20) and 6 women of 22-35 years (N=6) are spent 25 years. The used installation included veloergometr KE - 12 with digitizer KE - 12 MEDICOR and pulsotahometr 0-84 with the device, reformative pulsovye intervals in number sequences by means of the computer program «Pulse» (R.M.Grechishkin, etc., 2005).

In 1st series after 5-8-минутного habituations of examinees (N=14) a male to a starting position sitting on veloergometre were registered 120 cycles of warm reductions (R.M.Baevsky, 2001). Then examinees during 5 mines, visually being guided by a board veloergometra, carried out pedalirovanie in 150 Vt to sustain CHSS within the central contour of control RS (V.L.Karpman, 1987) and to maintain a load of the given level during experiment, regulating, thus, RS by means of muscular activity.

In 2nd series the same examinees in similar conditions worked on veloergometre, visually being guided on the monitor of the computer and aspiring, varying efforts of muscles of feet to replicate values of duration of a cardial cycle (DSTS), averaged of received in 1st series. Registration RS, as well as in 1st series, was spent to, to an operating time, and in 3 minutes after its terminal. Thus, regulation DSTS was carried out with participation of the visual analyzer and sensomotor component of muscles of feet more expressed in comparison with 1 th series (the complicated biological feedback).

In 3 th series individual researches of men of 19-25 years (N=4) to which in the conditions similar to 1st series 5-minute reproduction of values DSTS equal of 50 % between initial and before revealed size CHSS was offered are carried out.

Men participated in 4th series (N=3) 19 - 25 years with 21 registration RS during 5 mines at performance of constant ladder-shaped work on veloergometre.

Values DSTS replicated on the first 3 mines have compounded 20, 40 and 60 % from a difference between initial and maximum DSTS 1st series. On 4th and 5th mines the conforming decrease in a load to 40, 20 % and cessation of work then on 4th mines of the regenerative season final registration RS (fig. 1) was carried out was carried out.

In 5th series in 81 experiment 7 men and 6 women are surveyed. In 1st part of researches (control) examinees in position sitting listened own RS, transformed to sound signals, for experimentally established time - 13 minutes In 2nd part examinees listened own RS in an initial state (1st stage) and after switching-off of its scoring rhythmical influence by the computer metronome which has been adjusted on CHSS of the examinee, lowered on 10 ud/mines (2nd stage) moved. Thus the examinee was offered to listen attentively to a replicated rhythm, mentally comparing it with the own. At 3rd stage frequency has been lowered on 20 ud/mines, on 4th - for 30 ud/minutes Then, after 3 mines of rest with listening of own sphygmus, two-minute registration RS (5th stage) again was carried out. In 3rd part the metronome was adjusted on CHSS, the raised on 10, 20 and 30 ud/minutes

At matematiko-statistical analysis RS indicators were studied: H () - average value of a file karidointervalov; Mo () - a fashion; AMo (%) - voltage of a fashion; IN (Island E) - a strain index reguljatornyh systems; D (с2) - a dispersion; Cv (%) - variability quotient; r1 - linear correlation quotient; N (Island E) - indicator Harsta.

Spectral characteristics RS: OCH (мс2) - general spectral vigour RS; VCH (мс2) - vigour of a high-frequency component of a spectrum; LF (мс2) - vigour of a low-frequency component; ONCH (мс2) - vigour of very low-frequency component; NCH/VCH (Island E) - the attitude of a low-frequency component of a spectrum to high-frequency.

In work it is used correlation and regressionnyj analysis with exarticulation of linear and nonlinear interrelations.
