A characteristic feature of the life activity of modern children and adolescents is the couch potato, mostly "sedentary" lifestyle. Biomedical and psychosocial significance of motor activity (MA) stipulates the necessity of the substantiation of scientific and methodological approaches to the formation of the motivation to exercises and sports in children. The purpose of the study was in the scientific substantiation and the delivery of medical, pedagogical and neurophysiological prerequisites for the formation of the motivation to increase MA in students in current conditions of their life activity.

Psycho- and neurophysiologic investigation of 66 Navy specialists aged 18-71 has revealed the consecutive age-related worsening of different components of operators' activities with predominant and more early disorders in the processes of sensomotor coordination and attention. Apparently the age-related changes in functional state of certain cerebral areas underlie the observed disorders in operators' activities. It is supported by the results of correlation analysis between neurophysiologic and psychophysiologic indices.

The effect of omega-3 polyunsturated fatty acids on the psychophysiological state of an operator was studied and mechanisms of the drug action were analyzed based on the EEG data. Changes in the psychophysiological and hemodynamic characteristics, EEG, and catecholamine excretion after a 30-day administration of eiconol--a complex of unsaturated fatty acids--in a daily dose of 8 g were studied in a group of 16 middle-aged healthy male operators. It was established that eiconol decreases systolic arterial pressure, reduces adrenalin excretion with urine, imparts the sense of well-being, improves the parameters of activity and the attention stability and concentration, and decreases the level of static tremor.

The study of EEG and psychophysiological parameters and their correlations in 10 healthy volunteers after single oral administration of bromantan in comparison with placebo revealed favourable influence of the drug on operators' functional state. By EEG-profile (increase in middle-frequency alpha-rhythm power with lowering of powers in delta- and beta1-bands) bromantan is similar to many drugs with moderate psychostimulating, antiamnestic and antihypoxic properties. Bromantan does not alter the subjective state and principal components of operators' performance in untired men but promotes the appearance of EEG-signs of moderate vigilance rise and forming of productive action state coupled with favourable for precise motor performance tremor reduction.
