| Introduction:Since the sole of the foot, as the first organ that is in contact with the ground, with the help of longitudinal-internal arch structure, is responsible for transmitting ground reaction forces to higher organs, the purpose of this study was to investigate the effect of drop. Methodology: 14 active young women with flat anatomical structure [with mean age 24.75 years, height 160.85 cm and mass 51.82 Kg] and 14 active young women with normal anatomical structure of the sole of the foot [with mean age 25.33 years, height 161.16 cm and mass of 53.23 kg] After evaluating a flat foot with a photo scanner, they participated in this study voluntarily. Markers according to Planck method and imaging with Coalitions 8-camera system, kinetic information with two Kistler forceplates, in case the subject made a 50 cm step on the first forceplate of the biped landing, then jump upwards and then Finally, it landed on the second force plate and was collected. Results: In the study of the studied kinematic variables, only velocity Foot and leg angles in the jumping stage and wrist, leg and thigh angles in the second landing stage in people with flat and normal soles showed a significant difference. The results of statistical tests for the kinetic variables of landing jump landing skill showed that the loading speed in people with flat feet is done in a longer time. Meanwhile, ground reaction forces in all three directions in people with flat feet significantly increased. Discussion & Conclusion: Considering that the decrease in internal longitudinal arc has an effect on the reaction forces of the earth, while most of the kinematic variables of motion did not differ between people with flat and normal soles, it seems that the complexity The anatomical structure of the foot and the consequent ability of the foot to develop rapid compensatory mechanisms of the foot to communicate with new positions, as well as the level of physical activity and subsequent increase in muscle strength can greatly reduce the lack of internal longitudinal arch. Train young women to practice and actively. |
