Use of a method of share tendencies in the analysis time of some R-R intervals of the electrocardiogram after performance of 20 knee-bends and after 1 minute of restoration has allowed to establish a role of the centers of vegetative nervous system in restoration of a rhythm of heart at 4-th level of dynamic hierarchy. After 20-ти knee-bends and through 1 minutes of restoration the maximum vegetative centers of the central contour dominate. In interaction of the central and independent contours each center entering into them is characterized with distinctive features of dynamics which are shown in an increasing role of the centers of an independent contour after 1 minute of restoration.

Autonomic Nervous

A atuação do sistema nervoso autonômico está diretamente associada à condição fisiológica geral, sendo utilizada inclusive como demarcador de condição clínica, bem como indicador de risco para doenças cardiovasculares. No entanto, os estudos dessas relações têm sido conduzidos prioritariamente em população adulta. Nesse sentido, o objetivo do estudo foi analisar a associação entre prática habitual de atividade física, pressão arterial (PA) e variabilidade da frequência cardíaca (VFC) em crianças e adolescentes em Londrina, Paraná, Brasil. Estudo apresenta delineamento transversal, de modo que a amostra foi composta por 42 alunos da rede estadual de ensino, de ambos os sexos com idade entre 10 e 17 anos. Avaliou-se a massa corporal e estatura. Foram coletados ainda valores de PA sistólica e diastólica, VFC e a prática habitual de atividades físicas (PHAF) em diferentes domínios (geral, tempo livre, lazer e escola). O teste qui-quadrado foi empregado para avaliar as associações. Não foram identificadas associações estatisticamente significativas entre as variáveis cardiovasculares e a PHAF. A prática geral de atividades físicas habituais, bem como seus diferentes domínios, sejam eles no lazer, escola e tempo livre, não se associaram à valores aumentados de pressão arterial, bem como com os indicadores do comportamento autonômico de crianças e adolescentes.   Palavras-chave: Atividade Física.

Criança e Adolescente.   Abstract The role of the autonomic nervous system is directly related to the general physiological condition, including being used as a clinical condition path as well as a risk indicator for cardiovascular diseases. However, studies of these relationships have been conducted primarily in the adult population. Thus, the study aimed to analyze the association among habitual practice of physical activity, blood pressure (BP) and heart rate variability (HRV) in children and adolescents from Londrina, Paraná, Brazil. The study presents a cross-sectional design so that the sample consisted of 42 students from the state school system, of both sexes, aged between 10 and 17 years. Body mass and height were evaluated. Systolic and diastolic BP values, HRV, and habitual physical activity (HPA) were also collected in different domains (general, free time, leisure, and school). The chi-square test was used to assess associations. No statistically significant associations were identified between cardiovascular variables and HPA. The general practice of habitual physical activities, as well as their different domains, either leisure, school, or free time, were not associated with increased blood pressure values, as well as with the indicators of the autonomic nervous system in children and adolescents.   Keywords: Physical Activity.

The objective: studying of features of the psychoemotional and vegetative status at women with placental dysfunction at the previous pregnancy. Patients and methods. Complex clinical-laboratory examination of 89 women, from which was conducted: control group – 42 obstetrically and somatically healthy multipara, delivery through natural patrimonial ways; І group – 47 women with placental dysfunction at the previous pregnancy. Carried out a cardiointervalografia by means of a single-channel electrocardiograph and used a scale questionnaire of a condition of the pregnant woman. Results. It is established that regulation of cardiac rhythm at women at the previous pregnancy happens to placental dysfunction in the conditions of an autonomous contour which controls normal work of heart and vegetative nervous system. Further, there is an expressed strain of regulatory mechanisms that is shown by centralization of management of cardiac activity and sharp rising of activity of sympathetic nervous system. At the final stage influence of the central contour considerably decreases and patofunctionale vegetative equilibrium is again formed. Conclusions. The received results need to be considered when developing tactics of conducting pregnancy at these women. Key words: placental dysfunction, vegetative and psychological status.

AbstractBackground: The purpose of the research was to check opinions of students of various stages of education in the Pomeranian province about the attractiveness of Nordic Walking in comparison with other activities.Material/Methods: About 500 intentionally selected students participated in the survey. These were students of 11-18 years of age. Half of them participated in Nordic walking PE lessons. The researched students’ schools were localized in the Pomeranian province in Poland. Methods of a diagnostic survey using two questionnaires were applied. The first one was used to assess the level of students’ physical activity and was also used to research health behaviours of children and adolescents in Europe (HBSC). The second one - our own - was created to asses the attractiveness of Nordic walking. In the first part, the subjects ranked Nordic walking in comparison with other forms of physical activity. In the second part, they declared eagerness to attend such lessons.Results: The collected data imply a vast diversity of students’ opinions about the attractiveness of Nordic walking in comparison with other forms of physical activity and indicate the need to do research in the area of students’ preferences in planning PE lessons at school.Conclusions: It seems that in subsequent years of education, NW will gain followers among this group because it is a natural form of movement, whose health effects are starting to be seen not only by teachers but also by students
