“…On the basis of studying and processing the research data of the other authors (Bouchard, 2012, Kipp, 2017, Lutsenko, Kоvalenko, 2017 and according to the results of our study, it was found that the motivational interest of students of different institutions of higher education (non-sport specialties) in physical education classes is extremely low (Cline, Gammage, 2015, Han, Gabriel, Kohl, 2017, Zarei, Memari, Moshayedi, Mosayebi, Mansournia, Khoo, Morris, 2016). It directly affects health and disability.…”

The purpose of our study was to determine the level of motor activity in students, as well as to promote the formation of motivation to engage in physical sports. University students (n= 54, age 17-21 years) divided into 2 groups according to physical activity and sex. For the research, the self-developed questionnaire was used and processed by the statistical method with determining the relative parity indexes. The results of the research allowed studying the student's attitude to physical education in universities and independently, to assess the subjective state of health of different grade students, the reasons for abandoning physical exercises. The results are consistent with satisfaction with classes at university and the reasons for abandoning additional classes. Girls prefer classes of non-traditional types of PE that are not included in the program of the higher educational institutions and require significant financial investments that students cannot afford. Male students prefer sports games, and although they are included in the program, there are no free sections. Students pay little attention to physical activity, thus they do not have the formed need for independent exercises in physical culture, and most of them prefer to be engaged in non-traditional health-improving forms of physical culture. The amount of motor activity physical education classes showed a clear training effect and can be considered as one of the benchmarks of the compensatory role of classes in eliminating hypodynamic. Also in the article, the authors consider motivation as a dynamic process of continuous choice and decision-making, based on weighing behavioral alternatives, explaining the purposefulness, organization, and sustainability of holistic measures to achieve a certain goal acts as an incentive to act with a certain motive.

“…At the beginning of the twenty-first century, the attention of researchers is drawn to the study of the variability of the duration of the interval R-R [7][8][9][10], blood pressure [11][12][13], shock volume [14], respiratory arrhythmia [15][16][17], and the relationship of wave changes in various hemodynamic parameters. This is due to the wide introduction of information technology to the theory and practice of medicine and physiology, high diagnostic value of parameters of regulatory rhythms of hemodynamics.…”

“…The power of R-R and BSV oscillations spectrum was calculated in standard frequency ranges of very low frequencies of 0-0.04 Hz (VLF), low frequencies of 0.04-0.15 Hz (LF), high frequencies of 0.15-0.4 Hz (HF), general oscillation power of 0-0.4 Hz (TP), and normalized power in the range of 0.15-0.4 Hz (HFnorm). Besides, spectral and cross-spectral density and the frequency of the highest amplitude oscillation peak of t-R-R and BSV in the LF range were estimated in the prone position at rest for 5 minute records, at tilt test from the 2nd till the 5th minute and in psycho-emotional test from the 3rd till 7th minute[10].…”

Seventy seven women with 17-19 years of age examined central hemodynamics and its wave structure at rest, with orthopedic and psychoemotional load in different phases of the ovarian cycle (OC). It was established that in the luteal phase of the OC in the lying position, the blood pressure was higher than in other phases. In orthoprost in the luteal phase, in comparison with other phases, the growth of cardiac rhythm wave strength in the range of 0.04-0.15 Hz is observed, their concentration and connection with oscillations of the shock volume of blood, and the leveling of differences in blood pressure levels. The involvement of spontaneous baro-reflex sensitivity of the studied states and reactions is discussed.

Purpose The current study aimed to investigate the time course of changes in choroidal circulation hemodynamics and their relationship to systemic circulation dynamics during the normal menstrual cycle in young, healthy women using laser speckle flowgraphy (LSFG). Methods This prospective study included 26 eyes from 13 young, healthy women (21.3 ± 4.0 years) with a normal menstrual cycle and 24 eyes from 12 young, healthy men (21.8 ± 4.4 years) as a control group. The macular mean blur rate (MBR), a quantitative index of relative blood flow velocity in the choroid, was measured using LSFG. MBR, intraocular pressure (IOP), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), and ocular perfusion pressure (OPP) were evaluated in the late follicular phase and mid-luteal phase in women and at baseline and 10 days after baseline in men, respectively. Results In the female group, IOP, SBP, DBP, MBP, and OPP values were significantly higher in the mid-luteal phase than those observed in the late follicular phase (P = 0.035, P < 0.001, P = 0.041, P = 0.001, P = 0.014, respectively). The average macular MBR values in the late follicular phase and mid-luteal phase were 12.7 ± 5.3 and 13.7 ± 6.6 (+7.7 ± 19.4%), representing a significant increase in the mid-luteal phase (P = 0.041). The rate of change in MBR exhibited a significant positive correlation with changes in DBP and MBP (R = 0.456, P = 0.019 and R = 0.474, P = 0.014). However, there were no significant changes in any of the factors in the male group during the study period. Conclusions Our results suggest that in young, healthy women with a normal menstrual cycle, choroidal blood flow velocity decreases during the late follicular phase and increases during the mid-luteal phase, depending on systemic circulatory dynamics.
