        김성섭(Sung Sup Kim),백승철(Seong Chul Ba다),김지태(Ji Tae Kim) 한국사회체육학회 2013 한국사회체육학회지 Vol.0 No.54

        The purpose of this study was to examine characteristics in two groups by comparatively analyzing the kinemetical variables of bilateral symmetry on lower extremity according to skill level in Taekwondo. The group with experts was selected 9 exhibition members at Yuniversity with over 7 years of career in Taekwondo. The group with non-experts was selected 9 club members at Yuniversity with under 1 year of career in Taekwondo. The bilateral symmetry on lower extremity was limited to Do lryeochagi out of Balchagi(an act of kicking) in Taekwondo. The statistically significant difference was indicated in all variables except the flexion and extension of hip angle in the lower extremity joint angle. The bilateral symmetr y could be known to be excellent. The group with non-experts showed the bigger difference in lower extremity joint angle than the group with experts, and showed the statistically significant difference in variables of required time and peak tiptoe synthetic rate, thereby having been indicated to be short of the bilateral symmetry.
