Popis: PURPOSE This study investigated the effects of Taekwondo training of foot angle application on Pelvic stabilization and trunk tilt. METHODS This study investigated the effects of Taekwondo training of foot angle application on pelvic stabilization and trunk tilt. 80 boys aged 11 to 13 years old were selected, then reselect 20 people of exercis group and 20 people of control group from Taekwondo trainees of elementary school who have length difference to their legs and trunk tilt called R-body type (right leg is long) group. Taekwondo Training of foot angle application was conducted once for 60 minutes, three times a week for 12 weeks. RESULTS After 12 weeks of training, In the trunk tilt, exercis group’s neck tilt, spine tilt, pelvis tilt differences between front and back and leg tilt left were significantly decreased. In the pelvic X-ray examinations, exercise group’s ilium height, difference between right and left ilium width, length difference between right and left obturator foramen height, length difference between right and left sacrum width were significantly decreased. In the correlation between trunk tilt and X-ray examination, there was positive correlation between neck tilt and obturator foramen width. Also there was positive correlation among spine tilt and ilium height, sacrum width. There was positive correlation between pelvic tilt and length difference between right and left ilium width. And there was positive correlation between length difference between right and left legs and length difference between right and left ilium width, obturator foramen width. CONCLUSIONS Taekwondo training has been shown to stabilize the pelvis through strengthening muscles that support the lower limb and spine, improve leg length and leg inclination, and correct the trunk slope through human body compensation.
