STATE OF AUTONOMIC NERVOUS SYSTEM OF MEDICAL HIGHER SCHOOL STUDENTS AND ITS RELATIONS WITH THEIR PHYSICAL ACTIVITY AND OPERATION WITH THE COMPUTER

Abstract

The state of autonomic nervous system of the first-second years students and its relations with their physical activity, the experience and operation duration with computers have been explored. The observed base vegetative tonus was vagotonia and eytonia mainly (93.2%), vegetative reactivity was asympathetic and sympathetic (77.0%) mainly. Autonomic nervous system sympathetic part excitability in orthostatic test in 61.1% of the students was norm, while parasympathetic part reactivity in oculocardiac test was norm or reduced (72.8% of students) mainly. Work with the computer during 3 hours and more a day enhances sympathetic influences on heart activity, but increase of total work time promotes to relative decrease of sympatetic tonus. Vegetative reactivity grows both with increase of the operating time with the computer and with increase of the sport exercises. duration.
