Influence of occupations by diving on bioelectric activity of a brain of children of 12 years was studied at single immersion under water with an aqualung. Power changes (мкВ2) alpha, beta, a theta - and delta-rhythms before immersion under water with an aqualung are investigated. After occupation by diving at boys at implementation of the factorial analysis of data of EEG two factors with a total accumulative contribution to the general dispersion of signs of 79,03% were allocated. The first factor had a percentage contribution from the general dispersion of47,85%, and also high factorial loadings on variables: alpha-rhythm (r=0,78), theta-rhythm (r=0,82), delta-rhythm (r=0,76). This factor can be interpreted as cognitive. The percentage contribution of the second factor from the general dispersion made 25,24%. The variable entered this factor - a beta-rhythm (r=0,98). The factor made of variable second group, it is possible to consider important for a direct assessment of attention and intellectual tension (an attention factor). After occupation by diving at girls at implementation of the factorial analysis of data of EEG two main components (factor) with a total accumulative contribution to the general dispersion of signs of 69,02% were allocated. Results of the factorial analysis testify to prospects of application of indicators of bioelectric activity of a brain for differential diagnostics of a number of functional conditions of the person arising at occupations by diving.
