Examining the impact of physical activity on sleep quality and executive functions in children with autism spectrum disorder: A randomized controlled trial.
Thirty minutes of weekday active play lifts sleep quality and impulse control in elementary kids with autism.
01Research in Context
What this study did
Tse et al. (2019) split elementary kids with autism into two groups. One group kept their normal day. The other group added 30 minutes of active play after school, Monday through Friday, for several weeks.
The team tracked sleep with wrist watches and tested two brain skills: stopping an impulse (inhibitory control) and holding facts in mind (working memory).
What they found
Kids who moved more fell asleep faster, slept longer, and woke up less. Their sleep efficiency rose.
They also got better at the stop-and-wait game, showing stronger inhibitory control. Working memory scores did not budge.
How this fits with other research
Older studies mapped the problem. Hodge et al. (2014) and Kellems et al. (2016) showed autistic children sleep worse than peers and that poor sleep feeds daytime aggression.
Berenguer et al. (2024) extended the link: better sleep boosts communication skills. Andy’s trial is the first RCT to prove movement can break the poor-sleep cycle.
Cummings et al. (2024) add hope. Their big review found autistic executive functions grow with age just like typical kids. Andy’s gains on inhibitory control stack nicely on that natural climb.
Why it matters
You now have a low-cost tool: 30 minutes of tag, trampolines, or obstacle course right after school. No meds, no devices. Just schedule the play, watch sleep tighten, and see self-control rise. Start Monday—track latency and night wakings for two weeks to spot the payoff.

03Original abstract
Sleep disturbance and executive dysfunction have been widely reported in children with autism spectrum disorder. While the positive impacts of physical activity on sleep quality and cognition are documented in children with typical development, similar studies in children with autism spectrum disorder are scarce. The objective of this study was to examine the impact of physical activity on sleep quality and cognition in children with autism spectrum disorder. A total of 40 children diagnosed with autism spectrum disorder (mean age = 9.95 years) were randomly assigned into two groups: physical activity intervention and control. Four sleep parameters (sleep efficiency, sleep onset latency, sleep duration, and wake after sleep onset) and two executive functions (inhibition control and working memory) were assessed. Results revealed a significant improvement in sleep efficiency, sleep onset latency, and sleep duration in the intervention group but not in the control group during weekdays. Moreover, a significant improvement in inhibitory control was shown in the intervention group but not in the control group. No significant improvement in working memory capacity was documented in either group (ps > 0.05). Our findings highlight the value of physical activity in improving sleep quality and cognition among children with autism spectrum disorder, but specific physical activity may be required to benefit individual executive functions.
