Can Dance Exergames Boost Physical Activity as a School-Based Intervention?

Abstract

Children need opportunities to have physical activity (PA). Using exergames could be a feasible and acceptable way to boost PA in middle schools. Our goal was to increase PA by 40 minutes per week and to determine how much time, if any, was spent in moderate-to-vigorous PA (MVPA). Eighty-four middle school youth were in a pilot study for 20 weeks: half in the Generation Fit (GenFit) intervention group and half in the control group. The GenFit group played the exergame for the first 10 weeks (Session 1), and the control group joined from 10 to 20 weeks (Session 2). The main outcome was exergaming time per student per week. Fifty-eight students completed the pilot after 26 youth at School C were excluded for administrative reasons. Of those remaining, 40 students at School A and 18 students at School B, the average age of the sample was 13.7 years (SD=0.6), and average body mass index percentile was close to 70. During Session 1, the average dance time per child was 49 minutes per week, versus 54 minutes per week in Session 2. Mean body mass index percentile decreased by 5.6 for children who participated in GenFit, compared with 0.2 for children in the control group. At end point, accelerometers showed over half of the dance time was spent in MVPA. Qualitative data showed that most children found the exergame acceptable. A dance exergame in middle schools offered opportunities for PA. About half of the exergame time was spent in MVPA. Exergames may be feasible and acceptable in middle schools to boost PA, and access could provide a way for schools to support the health of students.
