Zumbeat: Evaluation of a zumba dance intervention in postmenopausal overweight women

Abstract

Physical inactivity is a major public health concern since it increases individuals’ risk of morbidity and mortality. A subgroup at particular risk is postmenopausal overweight women. The aim of this study was to assess the feasibility and effect of a 12-week ZumBeat dance intervention on cardiorespiratory fitness and psychosocial health. Postmenopausal women with a body mass index (BMI) >30 kg/m2 or a waist circumference >94 cm who were not regularly physically active were asked to complete a 12-week ZumBeat dance intervention with instructed and home-based self-training sessions. Before and after the intervention, peak oxygen consumption (VO2peak) was assessed on a treadmill; and body composition and several psychometric parameters (including quality of life, sports-related barriers and menopausal symptoms) were investigated. Of 17 women (median age: 54 years; median BMI: 30 kg/m2) enrolled in the study, 14 completed the study. There was no apparent change in VO2peak after the 12-week intervention period (average change score: ´0.5 mL/kg/min; 95% confidence interval: ´1.0, 0.1); but, quality of life had increased, and sports-related barriers and menopausal symptoms had decreased. A 12-week ZumBeat dance intervention may not suffice to increase cardiorespiratory fitness in postmenopausal overweight women, but it increases women’s quality of life.
