The effect of physical activity interventions on youth with autism spectrum disorder: A meta-analysis.
Physical activity gives kids with autism clear, large boosts in motor skills, fitness, and social play—so schedule it like therapy.
01Research in Context
What this study did
Healy et al. (2018) pooled 29 smaller studies of kids and teens with autism. They looked at any program that got the kids moving—games, sports, yoga, horseback riding, gym workouts. They crunched the numbers to see how these programs changed motor skills, fitness, strength, and social play.
What they found
The meta-analysis showed medium-to-large gains in every area tested. Kids ran and jumped better, got stronger, made more friends on the playground, and kept up longer in PE class. The authors call the evidence “robust” across age, IQ, and setting.
How this fits with other research
Neuhaus et al. (2016) said the same thing two years earlier: exercise cuts stereotypy and lifts mood. Their review is a direct predecessor—same kids, same playful workouts.
Pickard et al. (2019) narrowed the lens to group sports only. They still found a small-to-medium social boost, matching Sean’s social result. The 2019 paper is a conceptual replication that keeps the story standing.
Bassette et al. (2023) took the idea into a real community gym. Three teens learned to plan and run their own workouts with a self-management app. Skills stuck for weeks, showing Sean’s meta gains can happen outside the lab.
Why it matters
You now have a green light to add movement to any behavior plan. Pick an activity the learner already likes—dance, martial arts, tag—then embed it before tabletop work. Track stereotypy, attention, and peer talk; you should see quick drops and quick gains. Share the gym story with parents so they keep weekend workouts going.

03Original abstract
UNLABELLED: The purpose of this meta-analysis was to examine the effect of physical activity interventions on youth diagnosed with autism spectrum disorder. Standard meta-analytical procedures determining inclusion criteria, literature searches in electronic databases, coding procedures, and statistical methods were used to identify and synthesize articles retained for analysis. Hedge's g (1988) was utilized to interpret effect sizes and quantify research findings. Moderator and outcome variables were assessed using coding procedures. A total of 29 studies with 30 independent samples (N = 1009) were utilized in this analysis. Results from meta-analyses indicated an overall moderate effect (g = 0.62). Several outcomes indicated moderate-to-large effects (g ≥ 0.5); specifically, moderate to large positive effects were revealed for participants exposed to interventions targeting the development of manipulative skills, locomotor skills, skill-related fitness, social functioning, and muscular strength and endurance. Moderator analyses were conducted to explain variance between groups; environment was the only subgrouping variable (intervention characteristics) to produce a significant difference (QB = 5.67, P < 0.05) between moderators. While no significant differences were found between other moderators, several trends were apparent within groups in which experimental groups outperformed control groups.

LAY SUMMARY: Results of the meta-analysis-a method for synthesizing research-showed physical activity interventions to have a moderate or large effect on a variety of outcomes, including for the development of manipulative skills, locomotor skills, skill-related fitness, social functioning, and muscular strength and endurance. The authors conclude that physical activity's standing as an evidence-based strategy for youth with ASD is reinforced.
