Abstract: Objective To explore the correlation among children's large muscle group movement development,growth and development and perception of movement ability,so as to provide scientific reference for the comprehensive assessment of children's physical and mental health. Methods A total of 178 children aged 7—8 years between May 2018 and October 2019 were selected into this study. All children completed height and weight measurement after admission. The third version of the Large Muscle Movement Development Test (TGMD-3) was used to evaluate the development of large muscle groups in children,and the Children's Perception and Social Adaptation Scale (PSPC-P) to test children's physical perception capabilities. Pearson correlation analysis was used to evaluate the relationship among motor development of large muscle groups,growth and development,and operational capabilities. Results Among the 7- to 8-year-old children,the mobility score in the TGMD-3 of boys was lower than that of girls,while the scores of control and the total score of TGMD-3 of boys were significantly higher(t=7.391,5.327,6.481,P<0.05).The scores of mobility,control and the total score of TGMD-3in 8-year-old children were significantly higher than those in 7-year-old children (t=6.035,7.121,6.092,P<0.05). The height and weight of boys aged 7—8 were slightly higher than those of girls (t=7.091,6.436, P<0.05). PSPC-P score was not statistically significant between boys and girls (P>0.05). The height,weight and PSPC-P score of 8-year-old children were all higher than those of 7-year-old children (t=6.093,7.163,5.992, P<0.05).Pearson correlation analysis showed that the mobility,control and total score of large muscle group were positively related to children's height,weight and PSPC-P score(mobility r=0.745,0.737,0.762;control r=0.698,0.794,0.751;total score r=0.711,0.721,0.745,P<0.05). Conclusions There is a close correlation among the movement development of the large muscle groups,growth and development,and the perception of movement ability in children aged 7—8 years. Children's movement measurement should be added to comprehensively evaluate the overall physical and psychological development of children.
