Abstract

Introduction. Young people are exposed to a range of information technologies in different environments, including home and school, but the degree of factors influencing information technologies are poorly understood. Materials and methods. Current research included children of 7th from, divided into 2 groups depending on the duration of using the computer. There were investigated the following cardio hemodynamic indexes: frequency of heart contractions, systolic and diastolic blood pressure, pulse pressure, average dynamic pressure, systolic volume and cardiac minute-volume. Results. The research results indicate that changes in cardio hemodynamic indexes were within the norm of age, but recorded statistically reliable decrease in the dynamics of the day and week in children from both studied groups. A further reduction of 10% (which shows a fatigue) on an average in the research of the dynamics of the day or week were registered in children who work more on the computer. The largest decreases of the indexes’ values in the dynamic of the day were registered an the last lesson and in the dynamics of the week - Friday. The individual analyses of the children indicate an increase and a decrease of the investigated values of cardio hemodynamic indexes. Conclusions. Cardiovascular hemodynamic indices recorded changes, show a strain of the body systems and as a result – the development of fatigue, which is recorded in children working more on the computer.
