Abstract: It has been reported that physical fitness of breast cancer patients is relatively lower due to the cancer treatment such as surgery, chemotherapy, or endocrine therapy. Previous studies have revealed that not only cardiorespiratory fitness but also muscle strength is lower among breast cancer patients than no disease women and these symptoms may aggravate the health-related quality of life. However, there is no study which has focused the physical fitness level in Japanese breast cancer survivors. The purpose of this study was to investigate the physical fitness level and the relationship between exercise habituation and physical fitness level in Japanese breast cancer survivors. Fifty breast cancer survivors participated in this study. Participants were assigned to either exercise habituation group (n=25) or non-exercise group (n=25). We evaluated exercise habituation using an original questionnaire and examined various physical fitness level. Body weight, body mass index, and percent body fat were significantly lower in the exercise habituation group than non-exercise group. T-score of cardiorespiratory fitness was significantly higher in the exercise habituation group than average Japanese women. These results suggested that exercise habituation is relative to body weight and cardiorespiratory fitness level in Japanese breast cancer survivors.
