The problem of optimization of the physical state of school students by means of physical education

The study of the influence of different training regimens on the individual components of the physical state of 7- to 17-year-old school students of different morphofunctional types was carried out. A complex of methods for determining the level of physical development, motor fitness, the muscular capacity for work, the state of the cardiovascular system, and child and adolescent morbidity was used. The study showed the absence of a universal index capable of characterizing the "physical state" on the whole, the measurement of which would make it possible to judge unambiguously the effectiveness of the training process. None of the motor regimens used ensured complete optimization of all the components of the physical state and a decrease in the students' morbidity. In the course of the experiment, there were many cases in which a training regimen aimed at improving the autonomic regulation of the heart exerted little effect on the total morbidity, a considerable increase in aerobic capacity (as evidenced by the PWC170 test) was not accompanied by an increased level of overall fitness, etc. It was shown that, to optimize different aspects of the physical state of age-matched students with the same constitutional type, it is necessary to use motor activity regimens that differ in their physiological action. © Pleiades Publishing, Ltd. 2009.
