CORRECTION OF AUTONOMIC DYSFUNCTION IN YOUNG WOMEN BY OPTIMIZATION OF COMPONENT BODY COMPOSITION.

OBJECTIVE: The aim: The article aims toevaluate the possibility of optimizing the state of the autonomic nervous system in almost healthy young females with different component body composition through physicalactivity and sensible nutrition. PATIENTS AND METHODS: Materials and methods: The study involved 30 young females. Body weight of women was measured both before and after the proposed weight correction program. Such parameters as body mass index (BMI, kg / m2),fat mass percentage(FMP,%),visceral fat content (VF,unit) and fat free mass content (FFM, %) using a bioimpedance analyser "TANITA BC-601"were measured. Also, the study of the state of the autonomic nervous system (ANS) based on the registration of the rhythmogram using the computer hardware complex "CARDIOLAB" (HAI - Medica) was carried out. RESULTS: Results: Analysis of the results of the study revealed that the regulation of functions in women with suboptimal ratio of adipose and muscle tissues in the body was carried out mainly through suprasegmental levels of regulation (VLF%) and was accompanied by a decrease in the activity of segmental autonomic influences.At the same time, the theoretical assumption about the possibility of correction of autonomic disorders by normalizing adipose and muscle tissueswas experimentally confirmed.Under the influence of a two-month program of body weight correction an increase in the functional activity of the autonomic control loop and improvement of the internal structure of the spectrum of neuroautonomicregulation (reduction of VLF-oscillations and increase of LF-effects and HF-effects) in the examined women were observed. CONCLUSION: Conclusions: Thus, physical activity and sensible nutrition have a positive effect on the rheology of adipose tissue and the mechanisms of regulation of body functions, so they can be used to correct their disorders.

Diaphragmatic breathing in biological feedback mode for correction of the psychophysiological state in medical students.

OBJECTIVE: The aim: The current study aimed to examine the possibility of correction of the psychophysiological state of the undergraduate students by diaphragmatic breathing sessions in the biological feedback mode utilizing heart rate variability. PATIENTS AND METHODS: Materials and methods: The study enrolled 86 students 18 to 20 years old. Assessment of the functional state of the ANS was performed bycardiointervalography (CIG) and analysis of the spectral indices of HRV by the hardware-software complex "Cardiolab" (КAI Medica, Ukraine). A complex assessment of the autonomic homeostasis was performed using IARS calculated by a special algorithm. Assessment of the psychophysiological state of students was performed by questionnaires. RESULTS: Results: Among the examined population, 45% of students were in the state of satisfactory adaptation, 43% - in the state of functional tension, and 12% - in the state of unsatisfactory adaptation. Students with poor level of adaptation and depletion of regulatory mechanisms had higher heart rate, systolic and diastolic pressure, and RR compared to the students in the state of satisfactory and strained adaptation. CONCLUSION: Conclusions: The findings suggest that the average intensity of psychosomatic complaints has significant differences between groups with varying degrees of tension of regulatory mechanisms.
