Condition of the Foot Arch in 7–14 Year–old Takewon–do Sportsmen with Flatfoot

Danyschuk A. T.

The purpose of the work was to study the state of the vaulted apparatus of the foot in 7–14 year–old taekwon–do sportsmen with flatfoot. Material and methods. We surveyed 50 children aged 7–14 years involved in taekwon–do. We determined the individual and group structural features of the foot: the foot length, the anterior section (deflection angles of the I and V fingers), the state of the longitudinal arch and its height by the K coefficient, the area of the supporting surface, the heel angle. The study was conducted using the Stritter plantography method. Results and discussion. Regardless of age, young taekwon–do athletes with flat feet differed from the healthy group by pronounced statistically significant changes in the main plantographic indicators: an increase in foot width, a decrease in the Weisflog index, an increase in Stritter and Stritter–Godunov indexes, an increase in the first toe and heel angle, an increase in the longitudinal arch feet. The correlation analysis showed that the development of I–II degree flatness was in strong inverse correlation with the Weisflog index, and also strongly correlated with the foot width, the Stritter and Stritter–Godunov indices, the angle of the first toe and the heel angle. At the same time, a weak correlation was established with the indicator of the transverse arch of the foot. Conclusion. There is a relationship between the development of flatfoot and changes in the anatomical and functional state of the foot, which consists in decreasing the Weisflog index, increasing the foot width, the Stritter and Stritter–Godunov indices, the longitudinal arch of the foot, the I–angle and the heel angle. Considering the strong correlation interrelation of the vaulted foot indicators with manifestations of flatfoot, it is necessary to use Weisflog, Stritter and Stritter–Godunov indices of the height of the longitudinal arch of the foot. As a result, it was established that an indicator of the anatomical and functional camp of the foot is stable, with a slight increase in flat footing and with winter signs. Analysis of pantographic indicators showing that with flat feet the width of the foot increased, the value of the index of the Stritter and Stritter–Godunov index, the index of the late crypt foot, the size of the finger and the foot can be clearly predicted.
