Rhythmic therapeutic exercise program for breast cancer survivors

INTERVENTION: After the baseline assessment, participants will be randomly assigned to one of two groups: group A (intervention) or group B (control). The sample allocation will be carried out using the block randomization method (block size of 4). In group A, the RyKaTheA program will be implemented. In contrast, the participants of group B (control) will be taught self‐stretching of main muscle groups, which will be performed without supervision. They will also be encouraged to remain active but not to participate in any exercise program during the study's timeframe. Participants will be assessed before the 8‐week exercise program, immediately after, and 16 weeks after the program has finished. CONDITION: Fatigue in breast cancer survivors ; Signs and Symptoms PRIMARY OUTCOME: ; 1. Cancer‐related fatigue will be evaluated using the Greek version of the Multidimensional Fatigue Inventory (MFI‐Greek version) and the Greek version of the Modified Fatigue Impact Scale (MFIS) at baseline, 8, and 16 weeks; 2. Functional mobility will be assessed using the Timed Up and Go Test at baseline, 8, and 16 weeks; 3. Physical activity will be assessed using 6 minutes walking test (6MWS) at baseline, 8, and 16 weeks; 4. Quality of life will be evaluated using the Greek version of the SF‐36 Scale at baseline, 8, and 16 weeks; SECONDARY OUTCOME: ; 1. Grip strength will be assessed using a hand dynamometer at baseline, 8, and 16 weeks; 2. Lower limbs’ muscle strength will be assessed using the 30‐sec sit‐to‐stand test at baseline, 8, and 16 weeks; 3. Balance will be assessed using the Functional Reach Test at baseline, 8, and 16 weeks; 4. Depression and anxiety will be assessed using the Greek version of the Depression, Anxiety and Stress Scale‐21 (DASS‐21) at baseline, 8, and 16 weeks; INCLUSION CRITERIA: 1. Breast cancer disease‐free women aged 45‐60 years (meaning that they completed their oncology treatment 2 to 6 months before enrollment in the study), except if they are receiving hormonotherapy 2. Willing to be assigned to any of the two study intervention groups
