Aim. The aim of the study was to compare the effects of aerobic exercise training and yoga on the functional capacity, peripheral muscle strength, quality of life (QOL), and fatigue in breast cancer survivors. Material and methods. A total of 52 patients with a diagnosis of breast cancer were included in the study. The patients were randomly assigned to 2 groups: aerobic exercise (n = 28) and yoga added to aerobic exercise (n = 24). Both groups participated in submaximal exercise 30 minutes/d, 3 d/wk for 6 weeks. The second group participated in a 1-hour yoga program in addition to aerobic exercise training. Functional capacity was assessed by the 6-Minute Walk Test (6MWT). Peripheral muscle strength was evaluated with a hand-held dynamometer. The fatigue severity level was assessed with the Fatigue Severity Scale (FSS). The QOL was determined by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire. Results. There were statistically significant increases in peripheral muscle strength, the 6MWT distance, and the perception of QOL in both groups (P < .05). Additionally, the group with aerobic exercise and yoga showed marked improvement compared with the aerobic exercise group in fatigue perception (P < .05). Conclusion. According to the data from this study, aerobic exercise training and yoga improved the functional capacity and QOL of breast cancer patients. Aerobic exercise programs can be supported by body mind techniques, such as yoga, in the rehabilitation of cancer patients for improving functional recovery and psychosocial wellness.
