Zumba Fitness® is a highly popular aerobic dance fitness program that combines different Latin Rhythm. Despite the attractiveness of Zumba, there is little evidence supporting the potential health benefits of this relatively new exercise approach.

PURPOSE: To investigate the effects of a Zumba Fitness® intervention on quality of life in inactive Ecuadorian workers.

METHODS: A total of 69 inactive (<150 min of physical activity/week) participants (age 38.8±0.93 yrs; women, 81.2%; men, 18.8%) completed a 5-week intervention attending Zumba Fitness classes 3 days/week, 60 minutes/class out from working hours. Quality of life using the SF-36 Health Survey was measured at pre-intervention, post- intervention and 2-months follow-up. The rating of perceived exertion by Borg Scale (0-10) was recorded after each Zumba class (mean RPE=6.35±0.10). Repeated measures ANOVA test was used to compare variables before, after and follow-up of the intervention.

RESULTS: Significant differences (p<0.05) were observed immediately after intervention (mean differences post-intervention ─ pre-intervention) in physical role (17.89±7.03), vitality (12.89±3.81) mental health (6.37±2.27) and health transition (16.96±4.50) subscales from SF-36. In addition, social function (10.37±4.13) and mental health (9.76±3.42) subscales showed a significant increase at 2-months follow-up (mean differences 2-months follow-up ─ pre-intervention). No interaction on the effects of the intervention was observed by sex.

CONCLUSIONS: A 5-week Zumba Fitness® intervention improves quality of life in Ecuadorian inactive workers at short and long-term. Funding was provided by the National University of Chimborazo, Ecuador (29-CI-2014-10-17-22).
