Physical Activity and Motor Performance: A Comparison Between Young Children With and Without Autism Spectrum Disorder

Purpose: This study aims to examine the differences in physical activity and motor performance between young children with autism spectrum disorder (ASD) and children with typical development (TD) and to investigate the relationships between the levels of physical activity and motor performance. Patients and Methods: Twenty-five children with ASD (mean age = 59.3 +/- 8.1 months) and 28 children with TD (mean age = 63.1 +/- 8.6 months) were recruited. The Actigraph accelerometer, Movement Assessment Battery for Children-second edition, and Assessment of Preschool Children's Participation were used. Results: Young children with ASD spent significantly less time in moderate and light physical activity and exhibited more sedentary behavior than did children with TD. Those children with ASD also had greater motor difficulties and engaged less frequently in physical recreation activities compared to their TD peers. Motor performance was significantly correlated with physical activity in all children. Conclusion: This study highlighted the specificity of the levels of physical activity, motor difficulties, and participation diversity in children with ASD comparing performances on children with TD. Additional research is needed to provide valuable information for early interventions.
