Features of the space-time characteristics of the gait of children and adolescents involved in sports

The study of the spatial and temporal characteristics of the gait of children and adolescents is an important task. The purpose of this study was to determine the spatial and temporal characteristics of the gait of children and adolescents of different age categories who systematically engage in sports.Methods. On motion capture complex Vicon in the Center for Collective Use "Three-dimensional study of the biomechanics of motion" of the Astrakhan State University, 43 children were examined: 22 children in the control group and 21 children in the study group.Results. Quantitative indicators of the spatial and temporal characteristics of the gait of children engaged in sports dancing were obtained and a comparative analysis of this data with the control group was carried out. An increase of walking speed and cadence, a decrease in the time of single and double support in male athletes in the 7-12 year old group was revealed; increased of walking speed and cadence, a marked decrease in the time of single support, a decrease in the limp index in female athletes in the 7-12 year old group; an increase the cadence in female athletes in the group of 12-15 years.Conclusions. Doing sport every day helps with the spatio-temporal changes of the walk among children and teenagers. The imbalance of the motor function is examined among girls, that doing sports between the age of 7-12, so that’s why it needs a special attention from doctors, traumatologist and orthopedists.
