The aims of this study were to 1 describe PA levels of girls enrolled in dance classes 2 determine the contribution of dance classes to total moderate-to-vigorous physical activity MVPA and 3 compare PA between days with a dance class program days and days without a dance class non-program days . Methods Participants were 149 girls 11-18 years enrolled in dance classes in 11 dance studios. Overall PA was assessed with accelerometry for 8 consecutive days and girls reported when they attended dance classes during those days. The percent contribution of dance classes to total MVPA was calculated and data were reduced to compare PA on program days to non-program days. Data were analyzed using mixed models adjusting for total monitoring time. Results Girls engaged in 25.0 0.9 minutes day of MVPA. Dance classes contributed 28.7 95 CI 25.9 -31.6 to girls total MVPA. Girls accumulated more MVPA on program 28.7 1.4 minutes day than non-program days 16.4 1.5 minutes day p 0.001 . Girls had less sedentary behavior on program 554.0 8.1 minutes day than non-program days 600.2 8.7 minutes day p 0.001 . Conclusions Dance classes contributed a substantial proportion 29 to girls total MVPA and girls accumulated 70 more MVPA and 8 less sedentary behavior on program days than on non-program days. Dance classes can make an important contribution to girls total physical activity. Keywords accelerometer children moderate-to-vigorous physical activity light .
