This study aimed to examine the relationship between qualitative evaluation of fundamental motor skills and the quantitative motor performances in preschool children (122 boys and girls:5.7±0.5 years) . Fundamental motor skills were assessed based on 5 tests:25 m run, standing long jump, jump over and crawl test, overarm throwing, and zigzag run. Movements were videotaped and evaluated on observational evaluation criteria of "whole-body movement sequence image" and "several movement components". Each motor performance was measured simultaneously. Children with superior skills in whole-body movement had significantly higher motor performances except for in the zigzag run using ANCOVA adjusted for sex, age, body height, and weight. Moreover, children with superior skills in several movement components had significantly higher motor performances except for arm swings in the 25 m run, the leap over in the jump over and crawl test, and all items in the zigzag run. These findings suggest that development of fundamental motor skills by qualitative evaluation may be related to the superior quantitative motor performances in preschool children.
