The research purpose was to acquire data about the resilient characteristics of the foot under the natural conditions in young persons of both sexes. The examination of the morphofunctional condition of the foot was carried out by means of the computerized plantography, involving the systemic analysis and graphical analytical interpretation of the digital image of the foot. Scanning of the plantar surface of the foot was carried out consistently under compressive loads on each foot which were equal to 50 % and 80 % of the person's body weight. The height of the longitudinal arch of the foot was measured concurrently Resilience coefficient, deformation coefficient, Young's module and Poisson's coefficient were calculated in both groups. The conducted research revealed that the highest deformation coefficient in the persons of both sexes was found along the vertical axis of the foot. The lowest deformation coefficient was revealed along the sagittal axis of the foot. The persons of both sexes had the greatest Poisson's coefficient along the frontal axis of the foot. Poisson's coefficient of the women foot in this axis was higher in comparison with young men. Tensile modulus or Young's modulus of the young men was greater than that of young women. The obtained data of the elasticity of the human foot make it possible to characterize its amortisation function in normal condition and the extent of its loss in various foot deformations. The proposed computerized diagnostic module and the computerized detection of morphofunctional parameters make it possible to carry out an assessment of the human foot elasticity.foot resilienceresilience coefficientdeformation coefficientYoung's modulusPoisson's coefficientcomputerized plantographyyouth ageупругость стопыкоэффициент упругостикоэффициент деформациимодуль Юнгакомпьютерная плантографияюношеский возраст[Перепелкин А.
