Abstract: This paper focus on the influence of KDL curriculum implementation on children's basic motor skills and physical health level. 4 pilot primary schools in a city were selected by convenient sampling and the classes from grade 1 to 4 were implemented with KDL curriculum. Before and after the implementation of the course, the differences of students' basic motor skills and physical health scores were analyzed by the Independent Samples Ttest.The correlation between indexes was analyzed by Pearson’s correlation and multiple linear regression analysis. Results show that: before and after the implementation of KDL curriculum, there were statistically significant differences in total mobile skills, manipulation skills and overall skills (P<0.05). In group comparison, there were statistically significant differences in mobile skills between groups of 8-year-girls, 8-year and girls (P<0.05). Except for the 6-year group and the 7-year-boys group, there were statistically significant differences in control skills and total skills among the other groups (P<0.05). There were statistically significant differences in total vital capacity, sit-forward-flexion, rope skipping and total scores (P<0.05); in group comparison, there was no statistically significant difference between groups of 6-year and 7-year (P>0.05), but between certain groups of 8-year and 9-year (P<0.05). No significant difference in statistics between basic motor skills and physical health scores except vital capacity index (P>0.05). Conclusions indicates that: KDL curriculum could effectively promote the development of basic motor skills and physical health of children aged 6-9 years. The basic motor skills changed significantly between 7-9 years old, and the main improvement was shown in motor control skills, and the physical health level changed significantly between 8-9 years old. But there is no correlation between children's basic motor skills and physical health level, which may be two independent development abilities.
