Physical activity patterns in youth with autism spectrum disorders.

Pan et al. (2006) tracked how much kids with autism moved during the day. They used small motion counters called accelerometers. The kids were in elementary or middle school.

The team wanted to see if activity rose or fell at set times. They also compared younger kids to older ones.

Elementary kids with autism moved more than the teens. There was no clear peak hour or daily rhythm.

In short, activity drops after the early grades.

Barry et al. (2025) talked to autistic adults and found the slide continues. Many left parent-run team sports and picked solo workouts like running or yoga. They wanted calm, not trophies.

Greenlee et al. (2024) linked more movement to lower anxiety and depression in autistic youth. Yet even the active kids still had high mood scores. This shows the drop in activity is also a mental-health risk.

Lin et al. (2010) saw the same low teen numbers in students with intellectual disability. Only eight in every hundred met exercise guidelines. Caregiver support predicted who stayed active.

If you serve autistic clients, plan for the cliff that comes after elementary school. Add teen choices that feel safe and self-chosen, like small-group yoga or short running clubs. Track mood along with steps. A quick caregiver survey on support can flag who may need extra help to stay active.
