However, Physical activity and Physical fitness in children with autism spectrum disorders have received little attention. The purpose of this study was to evaluate physical fitness in preschool children with ASD. Methods: A total of 31 children, aged 3 to 6 years, participated in this study: 13 children with ASD (Age=50.23 +/- 7.62 months, 2 girls and 11boys) and 18 children without ASD (Age=51.33 +/- 11.06 months, 4 girls and 14 boys). A fitness test battery was employed. Results: Children with ASD have lower performance in physical fitness tests. However, no significant differences were found in anthropometrics characteristics, physical activity time. screen-based time and physical functioning. Conclusions: Preschoolers with ASD show an early deterioration in physical fitness. Physical activity programs at pre-school level are necessary to stimulate these abilities in children with ASD.
