Physical activity levels of adolescents with and without intellectual disabilities during physical education and recess.

To compare physical activity levels in adolescents with and without intellectual disabilities during physical education and recess. Forty adolescents diagnosed with intellectual disabilities (inclusive classrooms, n=20; self-contained classrooms, n=20) and 40 age-matched typically developing peers (general classrooms) participated. All participants wore an Actigraph GT1M accelerometer for 5 consecutive weekdays during school hours. Three groups of adolescents were similarly active during physical education; however, adolescents with intellectual disabilities in self-contained classrooms were less active during recess than did the other two groups. In addition, they spent less percentage of time in moderate-to-vigorous physical activity during recess than did the typically developing adolescents. An inclusive, structured, and supportive environment promotes physical activity engagement in adolescents with intellectual disabilities.
