Relevance of the research topic. Studying the state of support-spring properties of the foot of primary school-aged children is an important indicator of their physical development. Particularly relevant is the study of the state of support-spring properties of the foot for children who are systematically engaged in physical exercises. Exploring the possible influence of physical exercises and other factors on the state of support-spring properties of the foot expands the scope of approaches for preventing their disorders. The purpose of the research is to assess the state of the support-spring properties of the foot of primary school-aged children who are engaged in hand-to-hand combat. Material and methods. 81 children of primary school age who systematically attend hand-to-hand combat classes participated in the study. The children's and parents' consent to participate in the study was obtained. Research methods included: analysis and generalization of scientific and methodological literature, Internet sources, anthropometric research methods, pedagogical research methods, mathematical statistics methods. To study the support-spring properties of children, the length, width of the foot, the height of the longitudinal arch of the foot, the Dahle angle were measured, the Weisflog Index, the Chizhyn Index were calculated, and the Ocheret method was carried out. Results. The overall number of deviations in the support-spring properties of the foot among primary school-aged children tends to decrease with age. The highest number of deviations was observed among 7-year- old children (77.78 % in girls and 75 % in boys). Regarding the nature of deviations in individual indicators of the support-spring properties of the foot, the highest number was found in the spring properties of the foot, specifically in the height of the longitudinal arch of the foot in a relaxed state and under load, according to the Ocheret method.The influence of body mass on the indicators of the support-spring properties of the foot was investigated. Conclusions. The cohort of primary school-aged children is characterized by a significant number of deviations in the basic structural elements as well as in their performance of the spring function. Studying the state of the support-spring properties of the foot allows for the elucidation of strategies for preventing their disorders.
