The efficacy of a 9-month treadmill walking program on the exercise capacity and weight reduction for adolescents with severe autism.

Researchers added a 9-month treadmill program to normal PE for teens with severe autism. They compared exercise scores and BMI to a group that kept regular PE only.

The study used a quasi-experimental design. That means groups were not randomly picked, but the team still tracked clear before-and-after numbers.

The treadmill group got stronger and lasted longer on fitness tests. Their BMI also dropped compared with the control group.

Kids who just kept usual PE showed little change. The extra walking made the difference.

Healy et al. (2017) and Pan (2014) show autistic teens start with low fitness and high weight. Pitetti et al. (2007) proves a long treadmill block can flip that pattern.

Waldron et al. (2023) got similar gains using parent-led home games instead of treadmills. Both studies ran months-long, both found positive motor change. The new twist: parents can deliver the dose at home.

Moya et al. (2022) moved the idea online for adults with ID. Web classes still raised activity and trimmed waist size. It extends the same long-exercise concept to a new age and tech format.

You now have three ways to run a long physical program: school treadmills, parent-led games, or web classes. Pick the one that fits your setting and staff. If you serve overweight autistic teens, add at least nine months of structured walking or active games. Track BMI and endurance each quarter to show families real numbers.
