The literature search was conducted until 10 July 2021 by two independent reviewers (Y.Z. and Y.L.) with the following electronic databases: PubMed, Scopus and Web of Science (Supplementary Materials). Search terms included "child" OR "children" OR "preschoolers" OR "boy" OR "girl" AND "fundamental movement skills" OR "motor skills" OR "motor development" OR "gross motor" AND "TGMD" OR "Test of Gross Motor Development". Specific search strategies can be found in the Supplementary Materials. In addition, we manually searched reference lists in some key previously published studies and reviews.
