Children in their motional activities have more and more contents of static nature, or even contents od dynamical nature that are not of sufficient quality to cause the appropriate transformation of the anthropological status. Because of a lifestyle like that, feet deformities occur, and they can cause pain in the lower extremities, disrupt the normal structure in relations of the lower extremities (X or O legs) and even cut back the child’s desire for further excercising of motional/sports activities. The goal of this research is to determine the effects of deformity removal program on samples of boys and girls at the age of 10 and 11. The analysis of determining the deformities was performed by Mayer’s method for valuation of feet posture at a total sample of 85 examinees, and the statistical verification of the reaction to the program was performed with the use of T – test for the dependent samples. The results obtained during the research have shown that the corresponding program may affect the reduction or removal of the analysed deformity. The program applied to this research can be recommended for further work and use on populations similar or identical anthropological features.
