Zumba fitness (Zumba) is a Latin-inspired dance-fitness program that blends Latin music and repetitive steps/dance moves that form a "fitness-party”. Despite its widespread popularity with more than 14 million people having participated in Zumba in over 186 countries, more evidence is needed to evaluate its effectiveness as a mode of exercise training across a variety of physiologic parameters. The purpose of this study was to compare the effect of Zumba training and aerobic training on body composition and balance in young obese women. Fourteen young obese women, aged 24.6±5.7 years, completed the intervention in two groups: Zumba training group (ZT; n=6) and aerobic exercise training group (AT; n=8). Participants in ZT performed the Zumba fitness at 60-80% of maximal heart rate, 60 min/session, and 3 sessions/week for 8 weeks, whereas participants in AT performed aerobic exercises including walking and/or jogging on a treadmill or elliptical machine as well as cycling on cycle ergometer at the same exercise intensity, frequency and duration as the ZT. Height (cm), body mass (kg), waist circumference (cm), hip circumference (cm), percent body fat (%), blood pressure (mmHg), resting heart rate (b· min-1), blood glucose (mg·dL-1), blood lipids (mg·dL-1), maximal oxygen consumption (VO2max, ml·kg-1 ·min-1), muscular strength (kg), and balance (sec) were measured pre- and post-exercise training, and the results were analyzed utilizing a repeated measures two-way ANOVA. There was a significant difference (p=.012) between ZT (12.2±3.5, 20.8±8.6) and AT (13.1±5.9, 13.6±5.0) groups for right leg balance time (seconds) with a significant difference (p=.022) in pre and post measures in the ZT group. Additionally, there was a significant difference (p=.032) seen in pre and post measures in ZT (8.8±6.2, 17.7±15.4) for left leg balance. Systolic blood pressure (p=.013) and diastolic blood pressure (p=.032) decreased significantly in both groups. There was no significant difference in other parameters after 8 weeks of training. The results indicate that Zumba may be a better exercise regimen than aerobic exercise to improve balance in young obese women as well as waist circumference.
