In 30 sedentary women aged 18–70 with stable heart failure (NYHA I–III) and documented left ventricular ejection fraction, Sacred Dances are being tested for non-inferiority to conventional physical training on 6MWT and EQ-5D-5L quality of life.
- Why it matters: Sedentary behavior and emotional stress worsen heart failure prognosis, while conventional exercise can face adherence and motivation barriers. Sacred Dances may improve fitness and emotional well-being, but comparative non-inferiority evidence is needed.
- What they did: A randomized, active-controlled, two-period crossover trial assigns participants to SD then PT or PT then SD, with 12-week phases and a 3-week washout. Primary outcomes are 6-minute walk test and EQ-5D-5L Index and VAS, analyzed with linear mixed models using intention-to-treat and multiple imputation.
- The result: Non-inferiority will be concluded using a 30-meter margin for the 6MWT difference, alongside quality-of-life endpoints. The protocol is ethics-approved and prospectively registered in ReBEC (RBR-85tkdz5).
