Interrelation of the indicators of the physical preparedness level and functional condition of junior schoolchildren organism

Abstract

Purpose: The aim of the work is to study the physical preparednes and functional condition of 7-10 year-old children’s with different level of physical health organism while tested by the running ergometer. Material: The following methods were used to solve the tasks: anthropometry, standard method, tonometry, dynamometry, functional tests of the cardiopulmonary system, method of physical health assessment. The assessment of the efficiency and respiratory and cardiovascular responses was carried out using methods of ergometry, gas analysis, spirometry, pulsometry and timekeeping. Results: Most of the surveyed 7-10 year-old schoolchildren had a low or below average level of physical health, amongthem disharmonically developed children prevailed. The level of physical preparedness on the basis of the results of running and strength tests is better in children with average and upper average levels of physical health compared with children with low and below average physical health. In schoolchildren with average and upper average levels of physical health, fewer heart rate abnormalities were observed in rest, during tested by the running ergometer, and they were more likely to be restored comparing to children with low or below average levels of physical health. According to the results of the ‘500m run’ and ‘600m run’ tests, it is possible to characterize the level of functioning the organism’s cardiovascular and respiratory systems, as evidenced by the significant correlation coefficients between the test results and the parameters of pulmonary ventilation, respiratory volume, respiratory rate, heart rate reductions, the level of oxygen consumption at different load levels when tested by the running ergometer. Conclusions: The peculiarities of functional condition and manifestation of motor qualities in junior schoolchildren’s with different levels of physical health are revealed.
