Objective: To explore the relationship between gross motor development and perceived motor competence among children aged 7-8 years old. Methods: Random cluster sampling method was used to conduct a test among 162 students aged 7-8(78 boys,84 girls)by using Test of Gross Motor Development Ⅲ(TGMD-3) and 3 and Pictorial Scale of Perceived competence and Social Acceptance for Young Children(PSPC-P). Results: There were no statistical significance of perceived motor competence in different genders,and ages among children(t=-0.82, -0.58, P>0.05). Gross motor development differed significantly in different age groups (t=-4.79, P<0.01). Eight-year-old group(63.10±5.70) scored higher than 7-year-old group(57.96±7.76).There exists clear association between gross motor scores and perceived motor competence (r=0.29, P＜0.01), as well as locomotor development and manipulative development with perceived motor competence (r=0.21, 0.24, P<0.05). Conclusion There are close correlations between gross motor development and perceived motor competence among children aged 7 to 8 years. Manipulative development shows obvious influences on perceived motor competence. No gender differences are found in perceived motor competence.
