[A decrease in the motor activity of children under the influence of technogenic air pollution].

Among multiple and various functions of the body, motor activity is essential. But it is little studied in schoolchildren. The present study was undertaken to investigate the impact of industrial pollution of the ambient air on the motor activity in old schoolchildren. At school, the motor activity of 8th-, 10th-, and 11th-form schoolchildren was found to decrease with age, the dynamics of its decrease was determined by not only sexual differences of pupils, but also by the technogenic ambient air pollutions.
