BODY POSTURE OF A JU-JISTU CHAMPION – A CASE STUDY

The aim of the paper was to evaluate a sportsperson’s body posture regarding spine position, foot arch as well as distribution of contact force on the ground of a champion training Ju-jitsu (a case study). A study of somatic characteristics has been carried out, namely height, body weight, length and width of feet and the area of foot sole. The level of longitudinal and transverse foot arch and balance of both feet has also been taken into account. The study of somatic characteristics and feet assessment have been carried out by the authors of the paper. In order to assess the level of somatic characteristics (height, body weight and BMI index) and the area of feet and the level of foot arch, own research results have been compared with Lizis’ results. DIERS Formetic III 4D system, which enables to analyse body posture, namely spine and pelvis, in a non-invasive manner that is safe both to patients and medical personnel, has been used to assess spine and body posture. The results are very accurate and thanks to rapid image transmission to computer software, data analysis has been carried out immediately after test performance.
