their body mass index (BMI) assessed. During testing, research assistants used the Observational System for Recording Activity of Children – Preschool Version (OSRAC – P) to assess physical activity and to provide information about the social environments during which children engaged in physical activity. The results of this study showed that all children spent 40.2% of session time performing light – to – moderate – to – vigorous physical activity and 13.2% in moderate – to – vigorous physical activity in free play sessions. During these sessions, children were among a group of peers 59.9% of the time with or without an adult present, in a one – on – one social setting 29.3% of the time with either a peer or an adult present, or solitary for 10.8% of the time. Children with autism spectrum disorder spent the majority of the time among a group of peers with or without an adult present, and only 8.8% of the time alone with a peer. When children with autism spectrum disorder were solitary, they participated in light – to – moderate – to – vigorous physical activity 70.3% of the time.
