Abstract: The authors probed into the relationships between the basic movement skills and sedentary behaviors of chil-dren aged 3-6, so as to provide a basis for intervening children sedentary behaviors. The authors selected 355 children aged 3-6 in Shanghai as the investigation objects; the basic movement skills were measured by TGMD-2, while the times of sedentary behaviors were reported by the parents as the agents. The results indicated the followings: the basic movement skill performance of children aged 3-6 in Shanghai needed to be improved; there were gender differences in displacement movement skills, the girls’ displacement movement skill performance was better than the boys’; with the increase of age, the basic movement skill score, the displacement movement skill score, and the object operating skill score, showed sig-nificant differences. The total time of sedentary behaviors was far beyond the recommended, mainly related to the time of non before-screen sedentary behaviors. The regression effects of the basic movement skills and the displacement move-ment skills on the total time of sedentary behaviors and the time of non before-screen sedentary behaviors were all signifi-cant. Evidently, the basic movement skills and the displacement movement skills in their sub-domain were the negative correlation factors of the total time of sedentary behaviors and the time of non before-screen sedentary behaviors. Improv-ing the displacement movement skills played a positive promotion role in reducing the total time of sedentary behaviors and the time of non before-screen sedentary behaviors of children aged 3-6.
