Res. 20(3):593-596. 2006.-Aerobic dance has been purported to help with weight management; however, it is not known if various forms of dance are as effective as traditional modalities. This study estimated energy expenditure by heart rate for 28 women participating in 4 modes of aerobic dance (Bodycombat [i.e., TAEBO]; Pump; Step; and RPM [i.e., spinning]) compared to 2 running speeds. Pump had significantly (p < 0.01) lower energy expenditure (8.0 ± 1.6 kcal·min?1) compared to the other classes (RPM: 9.9 ± 1.9 kcal·min?1; Step: 9.6 ± 1.8 kcal·min?1; and Bodycombat: 9.7 ± 2.0 kcal·min?1) and running at 8.05 km·h?1 (9.16 ± 1.53 kcal·min?1). Also, Step (p < 0.01), Bodycombat (p < 0.01), and RPM (p < 0.01) had significantly higher caloric expenditures than running at 8.05 km·h?1 but significantly lower than running at 8.37 km·h?1 (10.30 ± 1.72 kcal·min?1). In conclusion, RPM, Bodycombat, and Step aerobics were equally as effective as jogging between 8.05 and 8.37 km·h?1, and they met American College of Sports Medicine guidelines for weight modification and maintenance. Additionally, heart rate assessment provided a quantitative method for estimating energy expenditure and the effectiveness of different aerobic programs.
