Key words: physical development, visual and auditory deprivations, junior schoolchildren.
The purpose of the study was to investigate physical development of children aged 7-10 with sensory disturbances.
Developmental morphofunctional heterochrony gains its specific features at sensory deprivations, which is displayed in the accelerated development of single qualities at different age phases and slowdown of age changes at other phases.
Thus, as opposed to healthy boys the 7-year-olds with visual deprivation had low indices of the birth-death ratio, but higher anthropometric measurements. Boys with auditory deprivations had low anthropometric measurements and high functional indices. As for the girls, they were distinguished by high anthropometric measurements, but low values of vital capacity.
Most of 8-year-olds with sensory disturbances had low anthropometric measurements and high functional indices. The low values of the birth-death ratio were marked in 9-year-old boys with visual deprivation at high anthropometric measurements. Girls with auditory deprivations, on the contrary, had high values of the birth-death ratio and all children in the group – high strength indices.
According to the findings, adaptive-compensatory changes in the body of children with sensory deprivations result in the intensification of developmental heterochrony of morphofunctional development. These changes are a necessary condition of support of the optimal for specific age functional status in conditions of sensory disturbances.
