Development of Basic Motor Skills from 3 to 10 Years of Age: Comparison by Sex and Age Range in Chilean Children

Basic motor skills are recognized as fundamental movements that allow children to interact with their environment and are identified as the basic structure on which more complex movements are built. Objective: to identify the level of motor development of children from 3 to 10 years of age according to sex and age group. Methodology. We studied a sample with a total of 328 participants (girls = 170; boys = 158) at preschool (n = 154) and school levels (n = 174). The ages of the students ranged from 3 to 10 years, with a mean of 5.94 years (±2.53). TGMD2 was applied to identify motor development. Results: boys and girls present low levels of physical activity, with most of them in the very poor, poor, and low-average categories (n = 182, 55.5%). Levels of motor development in locomotion, manipulation, and general development by age show significant differences (p = 0.000). However, levels of development by sex are not significant in manipulation, locomotion, and gross motor skills tests, respectively (p = 0.150, p = 0.208, and p = 0.210), and in relation to chronological age and motor development age show significant differences (p = 0.000).
