The purpose of this study was to understand the level of exercise coordination ability of children with
developmental disorder, and to examine the effect of 8 weeks Taekwon gymnastics program on the
exercise coordination. Total 24 children with developmental disorder(11~16 yrs) were participated, and
randomly divided into three groups; Taekwon gymnastics(TA, n=8), physical education(PA, n=8), and
control group(n=8). All study participant performed their respective activity program for 8 weeks (2
times/week, 90 min/session). The Activity theme and contents of Taekwon gymnastics were chosen
considering the exercise development levels of Gallahue. Movement Assessment Battery for Children-2 was
used to measure the level of exercise coordination ability of children with developmental disorder. All
data were analyzed using a 3X2 repeated measure ANOVA with post-hoccon contrast test (p<0.05) to
identify the statistical differences. At the baseline, children with developmental disorder showed very low
ability of exercise coordination compared to children without disabilities (less than 5% of bottom line).
After 8 weeks Taekwon gymnastic programs, TK group only showed significant improvement on the
manual dexterity, balance, and total test score(p<0.05). While TK and PA groups, both showed the
significant improvement on aiming and catching task. In conclusion, 8 weeks of Taekwon gymnastics was
effective to improve the exercise coordination ability in children with developmental disorder.
