This study examined the effects of a 48-week exercise-based intervention on the metabolic profile, autism traits, and perceived quality of life in children with autism spectrum disorder (ASD). We randomly allocated 64 children with ASD (aged 6–12 years) to experimental (n = 46) and control groups (n = 18) and used multilevel regression modeling to examine responses to receiving or not receiving the intervention. The experimental group showed beneficial effects on metabolic indicators (high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and total cholesterol), autism traits, and parent-perceived quality of life. Our results provide support for exercise and physical activity, including basic coordination and strength exercises, as important therapeutic interventions for children with ASD.
