Vigorous, aerobic exercise versus general motor training activities: effects on maladaptive and stereotypic behaviors of adults with both autism and mental retardation.

Elliott et al. (1994) compared two warm-ups for adults with both autism and intellectual disability.

One warm-up was hard aerobic exercise like brisk walking or jogging. The other was light motor games such as tossing a ball.

Staff watched each adult during a quiet session and later during a vocational task. They counted maladaptive and stereotypic behaviors after each warm-up.

The hard aerobic warm-up cut stereotypy and other problem behaviors. The light game warm-up did little.

The drop lasted through the quiet period and into the vocational task.

Frame et al. (1984) saw the same pattern in autistic children ten years earlier. Vigorous jogging beat mild ball play, so the adult finding is a clear replication.

Neely et al. (2015) extended the idea by letting each child exercise until they showed satiation signs like slowing down. They added that satiation-based exercise also boosts academic engagement, not just stereotypy reduction.

Vanderkerken et al. (2013) pooled 52 single-case studies on vocal stereotypy. Their meta-analysis says the biggest drops come from packages that add both antecedent and consequence parts. Exercise alone works, yet pairing it with a quick reinforcer or prompt may give even better results.

If you run a day program or job site, slot 15–20 minutes of brisk walking, stationary bike, or jogging before work time. No extra staff or gear is needed, and the behavior drop can last through the shift. Try it with one client next week and track stereotypy counts before and after.
