title: [Effect of supplementary intake of vitamins for 6 months on physical and mental work capacity of children beginning school education at the age of 6 years].
abstract: The authors have estimated the influence of polyvitamin intake on mental and physical working capacity of schoolchildren beginning their study from 6 years. A total of 74 children were under observation. They were divided into 2 groups: control (30 children) who were not given vitamins, and the main group (44 children) who received Undevitum (1/2 capsule, 2 times/day) during 6 months of the winter-spring period. It was found that already after 3 months of vitamin intake children studying in kindergartens or at school demonstrated increased number of letters looked through, muscle strength, decreased number of mistakes after introduction of a differential component. At the same time no favourable changes were recorded in the control group who did not receive vitamins. Six months after the beginning of vitamin intake the number of letters looked through by the children in the main group was higher by 22-37% than in the control group, the muscle strength was higher by 37-40%, the fatigue limit--by 113-119%, while the latent period of visual-motor reactions was lower by 25-30%, and that of audio-motor reactions--by 12-14%, as compared to the control group.
