Effects of Sacred Dances versus Conventional Physical Training on Functional Capacity and Quality of Life in Women with Heart Failure: Protocol for a Randomized Active-Controlled Crossover Non-Inferiority Trial (RED-WHF)
The RED-WHF protocol outlines a randomized, active-controlled, crossover non-inferiority trial designed to determine if Sacred Dances are as effective as conventional physical training in improving functional capacity and quality of life among sedentary women with heart failure.

Heart failure is a condition where the heart struggles to pump enough blood to meet the body's needs, a challenge that affects millions of people worldwide. For women living with this condition, the daily reality often involves significant physical limitations and a heavy emotional burden. Medical guidelines have long established that regular physical activity is one of the most effective ways to manage heart failure, improving how far a person can walk and how they feel about their life. However, sticking to a strict exercise routine is notoriously difficult for many patients. The motivation to move often fades, and the repetitive nature of standard gym workouts can feel like a chore rather than a path to healing. This creates a gap between what doctors recommend and what patients can actually sustain over time. Researchers are now exploring whether activities that blend movement with mental focus and a sense of community might offer a more sustainable alternative, providing the same physical benefits while addressing the emotional and spiritual needs that often go unmet in traditional medical care.
In a new study taking place in Salvador, Brazil, a team of researchers is testing a specific idea: can a practice known as Sacred Dances provide the same physical improvements as a standard exercise program for women with heart failure? The study, called RED-WHF, focuses on women between the ages of 18 and 70 who have a stable diagnosis of heart failure but have not been exercising regularly. The researchers are comparing two different approaches over a period of several months. In this crossover design, every participant will try both programs. Half the women will start with the Sacred Dances for twelve weeks, followed by a short break, and then switch to the conventional exercise program for another twelve weeks. The other half will do the reverse order, starting with the gym-style training and finishing with the dances. This design allows each woman to serve as her own control, making the comparison between the two methods very precise. During the twelve-week Sacred Dance sessions, the women meet twice a week for ninety minutes. About sixty of those minutes are spent actively moving, while the remaining time is used for instruction and group reflection. The conventional exercise sessions are shorter, lasting sixty minutes, but are carefully calibrated to burn roughly the same amount of energy as the dance sessions. Both programs are led by trained specialists who ensure the women move at a moderate pace that is safe for their hearts.
To measure success, the researchers rely on concrete, real-world tests rather than just asking how people feel. The primary measure of physical improvement is the six-minute walk test, where a woman walks back and forth in a hallway for six minutes, and the total distance covered is recorded. This simple test is a well-known indicator of how well the heart and lungs are working together. Alongside this, the women fill out questionnaires that measure their quality of life, their levels of stress, anxiety, and depression, and their sense of spiritual well-being. The study is specifically looking to see if the Sacred Dances can match the results of the conventional training. If the women in the dance group walk just as far, or nearly as far, as those in the exercise group, the researchers will consider the dance practice a successful alternative. They are also paying close attention to how many women stick with the program, as high dropout rates are a common problem with standard cardiac rehabilitation.
The researchers have set clear boundaries for their investigation. They are not claiming that Sacred Dances are a cure for heart failure, nor are they suggesting they replace medical treatment. Instead, they are investigating whether this specific type of movement can be a viable, non-inferior option for improving daily function and emotional health. The study involves thirty women and is being conducted with strict safety protocols, including medical oversight and psychological support. By the time the study concludes, the team hopes to have clear data showing whether a practice rooted in community, rhythm, and mindful movement can stand shoulder-to-shoulder with traditional exercise in helping women with heart failure live fuller, more active lives. The findings will help determine if the unique combination of physical motion and spiritual connection found in Sacred Dances offers a practical solution to the problem of low motivation in cardiac care.
