Abstract: In order to examine the effects of taekwondo training on preschool children’s execution function develop-ment, the authors selected 63 children aged 5-6 in 4 preschool classes in Beijing as the experiment objects, randomly selected 2 classes as the taekwondo training group, which includes totally 32 children, and the other 2 classes as the regular physical education class group, which includes total 31 children. The authors carried out 16-week taekwondo training intervention on the children in the taekwondo training group twice a week, and regular physical education courses on the children in the regular physical education class group. Before and after the intervention, the authors re-spectively measured the 3 subcomponents of the experiment objects’ execution function by using the Flanker inhibition control and attention test task, standard card classification task and working memory arrangement test in the NIH Toolbox, and revealed the following findings: the differences between the children in the taekwondo training group and the children in the regular physical education class group in measuring inhibition control and attention task (P<0.01), standard card classification task (P<0.05) were statistically significant, the taekwondo training group’s score was higher than the regular physical education class group’s score; after taekwondo training intervention, the children in the taek-wondo training group, whose scores measured before the task for inhibition control and attention task were at bottom 27%, had improved score differences that were statistically significant (P<0.05) as compared with those of the children whose scores measured before the task were at top 27%, the degree of improvement of the bottom 27% testees was greater than that of the top 27 testees, while the regular physical education class group did show such differences. The said findings indicated the followings: 16-week taekwondo training’s function in improving the inhibition control and perception flexibility of children aged 5-6 reached a statistically significant level; therein, the children with a lower in-hibition control baseline level benefited more than the children with a higher inhibition control baseline level.
