INSTRUMENTAL ASSESSMENT OF FUNCTIONAL STATES OF THE CNS, VANS AND HEMODYNAMIC INDICATORS OF STUDENTS WHO DO NOT HAVE TOLERANCE TO ENERGETIC DRINKS

The relevance of the research topic is due to the increasing popularity of energy drinks, especially among people of adolescence and young age. At the same time, there is scientific evidence that the uncontrolled use of energy drinks can harm the human body. The study was conducted to assess the impact of energy drinks consumption on the functional state of the central nervous system and the cardiovascular system. The study used theoretical methods (analysis of scientific literature) and empirical (instrumental assessment of the functional states of the central nervous system (CNS), autonomic nervous system (ANS) and hemodynamic parameters). The study involved 24 volunteers. The results showed that after the use of energy drinks there were significant changes in the functional state of the cardiovascular system in 13 subjects. In 10 of them, a deterioration in the functional state of the ANS was recorded on the basis of data indicating an increase in the integral index (PARS). In 3 subjects, a significant increase in blood pressure (BP) was recorded, indicating a hypertonic type of reaction of the cardiovascular system (CVS) to the impact of the energy drink. Also, evidence was obtained of the subjective sensations of the subjects, which can be explained from the standpoint of the individual reaction of the body to the stimulating substances that make up the energy drink. At the same time, the deterioration of functional states both at the central and vegetative levels may not be recorded instrumentally. Subjective deterioration of the state may be the body’s payment for maintaining the performance indicators of the leading physiological systems of the body, which can be influenced by the energy drink. Thus, the study allows us to conclude that the use of energy drinks can affect the functional state of the cardiovascular and autonomic nervous system. The results of this study may be useful in developing recommendations for the use of energy drinks, especially for people with diseases of the cardiovascular system and/or disorders of autonomic tone.
