A study of influence of mental and physical load of the indicators of heat rate variability in students with different dominant types of autonomic regulation

Abstract

Modern education in universities causes significant stress in students and strains the functional systems of their bodies. Analysis of scientific literature over the last few years convincingly shows that here has been a trend of worsening health among youth in many countries around the world. The issue of the health of students in higher education institutions in Ukraine is particularly acute. Firstly, this is directly related to the learning process itself, which is an extremely responsible and stressful period in the lives of modern young people, for the successful realization of which good somatic (physical) health is necessary. Secondly, this problem is related to deteriorating political, ecological, and economic conditions in Ukraine, as well as with unhealthy eating habits and a sedentary lifestyle. The causes of the worsening health of students can also be attributed to a low level of motivation for a healthy lifestyle and health culture among young people, which is associated with a lack of parental upbringing, namely, a lack of understanding from early childhood of the importance of a healthy lifestyle and the formation of a stable motivation for sports activities. It should be noted that an important role in the adaptation process during stressful situations is played by a personality trait such as resilience. In case of insufficient vitality in young people, apathy, reduced efficiency or a state of high tension can be observed. In particular, during teaching, it is necessary to take into account the individual characteristics of each student, as well as the peculiarities of their mental processes and states. Individuals with different individual typological properties of higher nervous activity (HNA) differ not only in the reactivity of the cardiovascular system, formation of the initial psychological background, but also in the activation of mechanisms for regulating heart rhythm.
