Objective of the study was to determine the level of self-regulation of emotional states in children engaged in badminton through the application of a biological feedback toolkit. Methods and structure of the study. A total of 34 primary schoolchildren attending the badminton section at the Municipal Budgetary Institution "Olymp" Sports School of the Elabuga municipal district of the Republic of Tatarstan and 30 non-sporting primary schoolchildren were involved in the study. When determining their level of emotional self-regulation, we applied the biological feedback method, which implied two practical courses conducted in a psychoemotional state correction center: muscular training and thermal training. The diagnostics of emotional regulation using the biological feedback toolkit was carried out before and after the badminton training session. Results and conclusions. The analysis of the muscular training results revealed that the level of muscle tension at the end of the training session, as compared to its beginning, fell. The children in their second year of training in the badminton section were found to have a muscular relaxation level of 678 µW at the end of training, as opposed to those in the first year of training (967 µW). Proceeding from the findings, we may conclude that long-term badminton training contributes to the formation of a muscle relaxation skill. By the end of the training session, the children improved the efficiency of performance of Jacobson's exercises, which consists in alternating muscle tension and relaxation. The statistical analysis revealed a statistically significant difference in the performance of Jacobson's exercises at the beginning and at the end of the training session. The thermal training showed no statistically significant differences in the peripheral temperature control before and after the training session

Efficiency of nickel and chromium removal from child's body through physical activities

© 2020 EDIZIONIMINERVAMEDICA. 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
