Psychological, motivational, and physical effects of a supervised exercise program in women with breast cancer undergoing adjuvant treatment: a pilot intervention study
This pilot study demonstrates that a supervised, individualized exercise program for women with breast cancer undergoing adjuvant treatment significantly improves physical strength and functional capacity while reducing anxiety and depression, thereby enhancing overall quality of life and intrinsic motivation for exercise.

Cancer is a profound challenge to global health, but for those who survive it, the journey often extends far beyond the end of medical treatment. Many women who have been diagnosed with breast cancer continue to carry the heavy physical and emotional weight of their recovery. They may face lingering fatigue, pain, or a sense that their bodies have changed in ways they cannot control. While doctors have long known that moving the body helps, the specific question of how to move safely and effectively while still undergoing treatment has remained difficult to answer. This is where the science of motivation becomes as important as the science of exercise. Researchers have found that how a person feels about their ability to choose their own path, how capable they feel in their actions, and how connected they feel to others can determine whether they stick with a healthy routine. When these feelings are nurtured, exercise becomes less of a chore and more of a source of strength.
In a recent pilot study, a team of researchers in Spain set out to test a specific approach for women currently fighting breast cancer. These women were in the middle of "adjuvant treatment," a medical term for the therapies—such as chemotherapy, radiation, or hormone therapy—that follow surgery to ensure the cancer does not return. The researchers wanted to see if a carefully designed, supervised exercise program could improve not just their physical strength, but also their mental well-being and their motivation to keep moving. They recruited sixteen women, aged between thirty-one and sixty-six, who had recently undergone surgery and were receiving ongoing treatment. The group met twice a week for fourteen weeks for one-hour sessions led by a specialist, with an additional hour of independent activity encouraged each week. The program was built on the idea that people move best when they feel supported, capable, and connected. The sessions included walking, stretching, strength training, and breathing exercises, all performed in a safe space with mats. Crucially, the instructors encouraged the women to make choices about their movements, explained the purpose of every activity, and fostered a sense of community through group walks and a shared messaging group.
The results of this fourteen-week journey were encouraging. The women who participated showed clear improvements in their physical abilities. Their ability to walk for six minutes without stopping increased significantly, covering a greater distance than before. Their grip strength, measured by how hard they could squeeze a device with their left hand, also improved. Perhaps most notably, the women reported feeling less anxious and less depressed. They felt a stronger sense of physical well-being and a greater belief in their own capabilities. The study found that the women became more motivated to exercise because they truly understood and valued the benefits, rather than feeling forced to do it. They also reported feeling more connected to their peers and more confident in their physical skills. While the group size was small, the data suggests that this type of tailored, supportive exercise can help women navigate the difficult period of active treatment, offering a way to reclaim a sense of control and vitality.
The researchers also looked at the women's body composition and found that their skinfold thickness, a measure of body fat, decreased in several areas. This is a meaningful change because carrying less excess fat can help reduce the severity of side effects from chemotherapy. Furthermore, the women increased the amount of vigorous exercise they performed, challenging the common fear that intense movement is dangerous during treatment. The study did not find changes in every single measure; for instance, their heart rate during exercise did not change significantly, and some measures of body fat remained stable. However, the overall picture points to a positive shift. The women felt better, moved better, and felt more capable of making choices for their own health.
This study serves as a reminder that recovery is not just about surviving the disease, but about living through the treatment with dignity and strength. By combining physical activity with psychological support, the program addressed the whole person rather than just the illness. The authors note that because this was a small study without a separate group for comparison, the findings are a starting point rather than a final conclusion. They suggest that future research should include larger groups and longer follow-up periods to confirm these benefits. For now, the work offers a hopeful glimpse into how a supportive, structured environment can help women find their footing again, proving that even in the midst of a grueling medical battle, the human spirit can find room to grow and strengthen.
