Introduction: This study aims to analyze the effect of two dance-focused and choreographic fitness classes on Health-Related Quality of Life (HRQoL) in sedentary worker women. Methods: 65 sedentary middle-aged worker women (38 ± 7.3 years old) completed a 16-week intervention randomly assigned to: (1) dance fitness group based on Zumba Fitness classes (DF group, n = 25)], (2) dance fitness + functional strength training group (DFFT group, n = 20), and (3) control group (n = 20). HRQoL was assessed by the 36-Item Short-Form Health-Survey (SF-36), which evaluates 8 dimensions of health [General Health (GH), Physical Functioning (PF), Social Functioning (SF), Physical Role (PR), Emotional Role (ER), Bodily Pain (BP), Vitality (V), and Mental Health (MH)] scored from 0 (worst) to 100 (best health status). Results: The control group statistically differed from both exercise groups in PF and PR, and from the DF group in SF and MH showing a lower score. No statistical differences were observed between exercise groups post-intervention, except in V. DF group showed increases in GH, PF, SF, V, PR, and MH post-intervention. Conclusions: A 16-week dance fitness intervention based on Zumba Fitness classes generates notable improvements in a wide range of HRQoL dimensions in sedentary middle-aged worker women, especially in V, PR and MH dimensions. 2020-07-27T11:49:12Z 2020-07-27T11:49:12Z 2020-05 info:eu-repo/semantics/article Barranco-Ruiz, Y., Paz-Viteri, S., & Villa-González, E.
