Associations Between Fundamental Motor Skill Domains and Physical Fitness Components in 5-11-Year-Old Children.

Abstract

High competence in fundamental motor skills (FMS) and adequate physical fitness (PF) levels are a solid foundation for acquiring an active and healthy lifestyle during childhood and adolescence. In this cross-sectional study, we aimed to compare gender and age groups and identify correlations between FMS and PF in young elementary school students. We used a structured questionnaire to gather sociodemographic information from parents, and we characterized the children's economic profile with the Brazil Social Economic Status Criterion. We collected FMS data using the Furtado-Gallagher Children Observational Movement Pattern Assessment System (FG-COMPASS), and we used the Brazil Sports Project Battery Test to measure PF levels. Statistical analyses involved descriptive data and inferential tests to determine group differences in FMS and PF levels. Hierarchical regression helped identify the associations between FMS and PF, as controlled by sociodemographic factors. Participants were 720 students (and parents) of both genders (383 girls, 337 boys; M age = 8.8, SD = 1.52 years) from grades 1 to 5 in an elementary school in a municipality in the western region of the Paraná state in Brazil. The results showed significant differences in children's motor skills and PF based on gender and age. The hierarchical regression model showed different combinations of flexibility, abdominal resistance, upper limb strength, agility, speed, and lower limb strength, which explained 33.7% of the variability in the global FMS index, 41% of the variability in manipulative skills, and 12.7% of the variability in locomotor skills. In addition, there was a positive association between FMS and PF related to neuromuscular development for both sexes, regardless of age.
