A Pilot Dance Intervention to Encourage Physical Activity Engagement for Adolescent Girls with Intellectual Disabilities.

Adolescent girls with intellectual disabilities (ID) are at risk for low physical activity (PA) participation due to their limited opportunities. To evaluate the feasibility and preliminary efficacy of a 12-week dance intervention to promote engagement in moderate-to-vigorous PA (MVPA) and increase cardiorespiratory fitness. The 12-week intervention included two 75-min weekly dance sessions. Continuous heart-rate (HR) monitoring assessed time spent below/at/above each girl's target HR zone. Cardiorespiratory fitness was measured by the 6-min walk test (6MWT). Survey items assessed participant enjoyment and participant and parent satisfaction. The mean (SD) age of 18 adolescent girls was 17.3 (2.7) years. Overall, girls attended 88% of sessions and spent 52.3% of each session in MVPA. Mean MVPA was unchanged across the 12 weeks, but the pattern differed across the three sites. We observed a non-significant pre-post increase of 74.6 feet on the 6MWT. Post-intervention surveys indicated that most girls liked the program, perceived improved fitness, and wished to continue dancing. The majority also reported a preference for a girls-only dance program exclusively for those with ID. Our findings suggest that dance is viable for promoting PA for girls with ID. More frequent exercise training is likely needed to improve cardiorespiratory fitness.
