Motor skills(MS), physical activity(PA) and physical fitness(PF) are important factors in preschooler's healthy growth. Thus, the aim of this study was to integrate the level of MS、PA and PF,so as to build an evaluation system of preschooler's physical activity index (PAIP). Method: Preschooler (n = 600) from kindergarten in Changsha, the capital city of Hunan Province in Central China were recruited, and a three-axis accelerometer (ActiGraph GT3X-BT) was used to the PA status of them, and the test of gross motor development three edition (TGMD-3) was used to the MS status of them, and national fitness test standard of China was used to PF status of them. We conducted simultaneous path modeling in AMOS to test moderation effects.
Based on the measurements of MS、PA and PF༌a PAIP model was built using a structural equation modeling (SEM) approach. This model combined physical fitness, physical activity and motor skills together and to reveals that the promotion of motor skills to the physical health of preschoolers has greater benefits than physical fitness and physical activity. At the same time, the evaluation index system and reference level of physical movement ability index of preschool children are developed, which provides an operational way to look forward to the development of physical health of preschool children.
The theoretical structure model of PAIP suggests that kindergarten administrators and physical education teachers should put the multi-directional development and types of motor skills of preschool children in the first place.
