Factorial structure of physical performance in children aged of 7-8 years


Full Text:


The given research is devoted to the comprehensive investigation of physical working capability within the whole range of accessible loads in healthy schoolchildren aged of 7-8 years (n=159). During the working process there were identifiedfive important facts determining the structure ofpupils ’physical working capability in the researched aged group. They include common working capability, aerobic alactant working capability, anaerobic glycolytic working capability, aerobic power and aerobic volume. The pointed out facts except the fact of common working capability, are associated with the maximum, sub maximum, large and medium zones of relative capacity respectively. During the study there were found out the expressed differences between boys and girls according to the development level of aerobic and anaerobic components ofphysical working capability. Therewith the most substantial differences were observed concerning the variables characterizing the working capability in zones of large and medium power dealing predominantly with aerobic muscle activity power supply, and the least valuable ones - in accordance with working indices in the sub maximum power dealing with anaerobic glycolytic system. The received data can be applied in solving practical problems of hygienic rating and control ofphysical loads value of different relative power during the process of physical education as well as in prenosological diagnostics of children’s health on the base of the evaluation of their organism’s adaptative capabilities.
