THE ROLE OF SPORT PARTICIPATION AND BODY MASS INDEX IN PREDICTING MOTOR COMPETENCE OF SCHOOL-AGE CHILDREN

ABSTRACT The purpose of this study was to investigate the association between Sport Participation (SP) and Motor Competence (MC) in school-age children, and to assess the mediation role of Body Mass Index (BMI) on this association. 707 children (332 boys, 375 girls) aged between 6- to 10 years participated in the study. Motor competence was determined using the Bruininks-Oseretsky Test of Motor Proficiency (BOT-2). Parents were asked about organized SP, categorized as 1) no participation, 2) partial participation and 3) consistent participation, and BMI was calculated based on the child’s height and weight. The results indicated significant differences for all MC components and total score for SP categories, all p < .05, with higher results for consistent participation in sports. For BMI, significant differences occurred in all components, with the exception of fine manual control and manual coordination. Our findings showed that SP was associated with MC, and BMI was not an important factor in these relationships. However, a small mediation of BMI was found, but only for obese children. In summary, we conclude that sport participation plays a relevant role in the development of motor competence in school-age children, and that association is, in general, not mediated by weight status.
