摘要：Background and Study Aim: Practicing capoeira requires improving movement, defense and attack techniques (kicks, transitions, dodge,
takedowns) as well as develops agility, coordination, praxis and co-contraction. Due to the specificity of the
training process, it can be assumed that physical exercises used in the training of athletes are a factor strongly
modeling their feet, which are the distal part of the musculoskeletal system. The aim of this research was the
post-exercise changes in the values defining selected features of foot structure in capoeira adepts advanced
in training experience.
Material and Methods: We examined 30 capoeira adepts with advanced training experience, aged 20-25 years, attending “UNICAR”
Capoeira Academy in Rzeszów. The study relied on the CQ-ST podoscope for pertinent measurements. The
following foot features and indices were measured: foot length and width, Clarke’s angle, heel angle (γ), hallux
valgus angle (α), and the V toe varus deformity angle (β). The data were analyzed based on the Student t
test and Wilcoxon test.
Results: There was a statistically significant increase in the value of foot width (p = 0.000) and Clarke’s angle of the
right (p = 0.001) and left (p = 0.000) foot under the influence of 1.5 hours of training, as well as an increase
in the values of the heel angle (γ) of the left foot (p = 0.000), hallux valgus (α) of the left foot (p = 0.028) and
varus angle of the Vth toe (β) of the left foot (p = 0.000).
Conclusions: Mechanical stimuli used during capoeira training improve the longitudinal arch of the foot. After 1.5 hour training
the feet widen, the transverse arch of the left foot decreases, as well as the increase in hallux valgus and
the Vth toe deformity of the left foot in adepts with advanced training experience. This indicates the need for
skillful dosing of exercises and combat elements excessively straining the forefoot in order to minimize permanent,
adverse changes within the anterior support zone.
