BACKGROUND: At present, a large number of people live in unfavorable environmental conditions that adversely affect the health of the population, including children. Therefore, it is necessary to look for ways and create methods for removing harmful substances from the body, including physical culture means.
METHODS: The following methods were used for the study: analysis and synthesis of literary sources, atomic absorption analysis, pedagogical experiment, pedagogical observation.
RESULTS: The research was conducted in a sanatorium located in a relatively environment-friendly area. More than 1000 preschool children participated in the study. To remove excess nickel and chromium we applied the following techniques in the experimental group: hiking using cold-protective clothing, swimming in the pool, combined effects of hiking and saunas, saunas and swimming in the pool. The control group followed the standard program of the sanatorium. The results of the research showed that the most effective way for removing nickel from the body of children living in unfavorable environmental areas is physical activity in the pool; for the removal of chromium the most effective way is the combined effect of aquatic physical loads and thermal-air loading.
CONCLUSIONS: The children from unfavorable environmental areas have higher content of heavy metals in the solid biological media; to reduce it, these metals must be removed through physical activity; the most effective way for removing nickel from the body of the children living in unfavorable environmental areas is the impact of physical exercises done in the pool; the most effective way for removing chromium from the body of the children living in unfavorable environmental areas is the complex impact of aquatic physical activity in combination with thermal-air loading.
