A Randomized Controlled Trial of the FMS - CrossFit Training Program(FCTP) to Improve School Readiness in Preschool Children With Autism Spectrum Disorder
Autism spectrum disorder (ASD) is an increasing public health concern, with preschool children often exhibiting persistent deficits in school readiness. However, targeted and developmentally comprehensive interventions remain limited. This randomized controlled trial will evaluate a 12-week Fundamental Movement Skills-CrossFit Training Program (FCTP) in 184 children with ASD aged 3-6 years, compared with a Treatment As Usual (TAU) control group. The program integrates progressive FMS training with CrossFit-style circuit training to improve motor competence, social interaction, and self-regulation. Primary outcomes focus on school readiness assessed by the Strengths and Difficulties Questionnaire (SDQ), while secondary outcomes include motor development, executive function, social responsiveness, and biomarkers. Assessments will be conducted at baseline, mid-intervention (8 weeks), post-intervention (12 weeks), and follow-up (20 weeks).
