Investigators plans to conduct a randomized, open, single center clinical study of Dragon Boat Race versus family unsupervised training to improve the physical function and quality of life in breast cancer patients to compare the effects of organized and supervised short-term dragon boat training versus unsupervised home training on body composition, physical function, and quality of life in women after breast cancer surgery. Participants will be assigned to the following intervention protocols at a 1:1 ratio:Dragon Boat Training Group (DB): Conduct 12-week dragon boat training under the guidance of professional coaches.Home-based Unsupervised Training Group (HG): Perform exercises at home independently according to instructional videos for 12 weeks.The primary outcomes are to analyze differences in body composition, physical function, and quality of life.The secondary exploratory outcomes include stratified factors such as menopausal status and surgical methods

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Dragon Boat Training Group (DB) | Experimental | The total training duration is 12 weeks, divided into cycles of 4 weeks each, with distinct training contents and goals for every cycle. Training sessions are held 3 times a week, and all participants train together on the same day. Each training session lasts approximately 60 minutes. In the first 4 weeks, participants spend half an hour training on land and the subsequent half an hour training on dragon boats. Then, from week 4 to week 8, they train for 20 minutes on land and 40 minutes on dragon boats. Finally, from week 8 to week 12, they only conduct 10-15 minutes of land training (as warm-up) followed by nearly an hour of on-boat training. This progressive training plan is designed to ensure that each participant can tolerate the training intensity as much as possible, preventing injuries caused by training. |
|
| Home-based Unsupervised Training Group (HG) | Active Comparator | The total training duration is 12 weeks. After a 15-minute warm-up (including walking, exercises, etc.), participants will perform the following 10 movements in sequence: squats, rowing simulation with rubber bands, lateral raises, sit-ups, shoulder presses, alternating bilateral lunges, dumbbell curls (for biceps), sit-ups, and planks. Each movement lasts 60 seconds, with a 10-second rest allowed midway through the same movement (i.e., 15 seconds of exercise followed by a 10-second rest, then another 15 seconds to complete the movement). A 20-second rest is permitted before moving on to the next movement. Once participants can complete 30 seconds of the same movement without needing rest or adjustment, the training intensity will be increased-progressing from one round of training (10 minutes) to two rounds (20 minutes) or even three rounds (30 minutes). |

| Physical function | Six-minute walk test (6MWT, m)：The test is conducted in an indoor, long, straight, and flat rectangular area with a 30-meter walking route, where participants walk back and forth repeatedly. They should walk at their usual pace and rhythm as much as possible, without the need for brisk walking or jogging. The distance walked by the participants after 6 minutes is recorded. The formula reported by Enright and Sherrill, which is based on body mass index (BMI) and age, is used to compare with the 6-minute walk distance (6MWD) of normal healthy populations (for males: 6MWD (m) = 1140m - 5.61 × BMI (kg/m²) - 6.94 × age (years); for females: 6MWD (m) = 1017m - 6.24 × BMI (kg/m²) - 5.83 × age (years)). |

| Psychological status | Self-report measurement method used to assess people's acceptance of their own bodies, respect and care for their bodies, and protection of their bodies from unrealistic beauty standards. All items are rated on a 5-point scale (1 = never, 5 = always), and the total score is calculated as the average of all items, so a higher score reflects a higher level of body appreciation. | 1 year |
