Dynamics of Judoka's foot arch

Background and Aim of the study. Many health problems are caused by a poor condition of foot arch. Foot arches of athletes are influenced by injuries. Barefooted walk is recommended as a prevention of foot arch problems. That is why we chose judoka as tested persons because their performance and training is always barefooted. Materials and Methods. We used drop test to assess the dynamics of judoka's foot arch. Our control group consists of nonathletic population (25 judoka, 25 nonathletes). We measured the length of the sole, height of os navicular in a sitting and standing position. Results. The dynamics of Judoka's right foot (average result of drop test 6.64 mm) is bigger than their left foot's (6.0 mm). Foot arch's drop of nonathletes is less than half of judoka's (2.62 mm of right foot, 3.54 left foot). Conclusions. Practicing judo formulates the feet arches. There is a difference between right and left foot arch dynamics depending on the preference guard in judo.
