Brief Report: Preliminary Efficacy of a Judo Program to Promote Participation in Physical Activity in Youth with Autism Spectrum Disorder.

Garcia et al. (2020) · Journal of autism and developmental disorders 2020
★ The Verdict

An 8-week community judo class can nudge up moderate-to-vigorous activity in youth with autism.

✓ Read this if BCBAs working with school-age or teen clients who need more daily movement.
✗ Skip if Clinicians focused only on verbal communication goals with no motor component.

01Research in Context

01

What this study did

Researchers ran an 8-week judo class for youth with autism. Kids met once a week at a local dojo.

They wore activity trackers before and after the program. The team wanted to see if judo would raise moderate-to-vigorous physical activity, or MVPA.

02

What they found

Daily MVPA rose from a large share to a large share of the day. The change was small but reached the edge of statistical significance.

Attendance stayed high, showing the kids liked the class. Sedentary time was not measured.

03

How this fits with other research

Pan (2008) watched kids with autism at recess and saw almost no MVPA. The new judo class gives one clear way to push those numbers up.

Pickard et al. (2019) pooled 21 studies and found group sports, including judo, give a small-to-medium boost to social skills in autism. The current study adds fresh evidence that MVPA can rise at the same time.

Bassette et al. (2023) went further, teaching teens to build their own gym workouts. Their self-management approach kept fitness gains for months, showing you can either run a short class or teach lifelong skills.

04

Why it matters

If you serve kids with autism, you now have a ready-made 8-week plan that fits into community centers. Pair the judo class with a self-management package for older clients to keep gains alive after the course ends.

03Original abstract

To examine the preliminary efficacy of an 8-week judo program to promote moderate-to-vigorous physical activity (MVPA) and reduce sedentary behavior (SB) in youth with Autism Spectrum Disorder (ASD). Fourteen children diagnosed with ASD participated in a weekly judo program over a period of 8 weeks. Participants wore an Actigraph accelerometer to measure activity levels at baseline and post-judo. All 14 children attended at least 75% of the 8 judo classes. Percentage of time spent in daily MVPA (8% vs 4%, p = .05) increased following the intervention. A high rate of participation and an increase in time spent in MVPA was observed following the 8-week program. Further research to examine causal mechanisms is warranted.
