Functional State Of Modern Schoolchildren With Different Physical Working Capacity Level

Abstract

The research purpose is to find out the influence of physical working capability level appeared at the maximal zone, submaximal, high and reasonable power to organism's functional state and effectiveness of intensive cognitive activity among children at critical periods of development under the conditions of informative-educational environment of modern school. 6-7 aged children (n=134) and 11-12 aged immature girls (n=221) related by the health state to the main medical group have taken part in the research. The research results allow to make a conclusion that at critical periods of development the physical working capability causes a significant influence on children's FS changes under intensive cognitive activity. A high level of aerobic and anaerobic glycolytic capabilities appeared predominantly at reasonable zones, high and submaximal power on one hand and a high level of anaerobic alactic capabilities appeared in the maximal zone power on the other hand provide the opposite functional effect. The first ones provide the decrease of extra psychophysiological reactivity, increase of intensive cognitive activity effectiveness, and possible, the personal anxiety decrease, the second ones in opposite provide predominantly hypermobility of autonomic systems of 6-7 supply of activity. The obtained data show that the improvement of intensive cognitive activity effectiveness among children and their FS normalization at the conditions of informativeeducational environment of modern school can be reached on the base of directed and balanced increase of physical working capability at different zones of relative power.
