Objective  To explore the relationship between motor skills and cognitive self-regulation ability of 4-6 year-old children, so as to provide a basis for the demonstration of multiple values of sports.

  Methods  165 4-6 year-old children were selected as the research objects. The development level of motor skills was tested by Bruininks-Oseretsky Test of Motor Proficiency-2nd Edition(BOT-2), BOT-2 sensitivity subscale, Movement Assessment Battery for Children-test-2nd Edition(MABC Test-2), and MABC Test-2 throw-in motor subscale; the cognitive self-regulation level of children was evaluated by learning related cognitive self-regulation test package.

  Results  Correlation analysis, logistic regression analysis and linear regression analysis showed that bilateral limb movement coordination, hand eye coordination, movement agility, movement balance were positively correlated with preschool children's cognitive self-regulation ability. After adjusting the interaction effects of month age and multiple movement skills, only bilateral limb movement coordination was significantly positively correlated with children's cognitive self-regulation ability. Boys' and girls' movement skills were positively correlated with children's cognitive self-regulation ability, with boys β=0.22, 95% CI=0.08-0.36 and girls β=0.16, 95% CI=0.04-0.29, respectively; however, there was no significant difference in the correlation between motor skills and cognitive self-regulation for different genders.

  Conclusion  4-6 year-old children's bilateral limb coordination skills are related to cognitive self-regulation. It is suggested that preschool sports educators should pay attention to the development and intervention of children's bilateral limb movement coordination games, and that families should develop children's coordination ability through regular parent-child sports interaction to promote the development of preschool children's cognitive self-regulation and the formation of good learning quality.
