Can a tailored exercise program boost motivation and Well-Being during breast cancer treatment?
NCT ID NCT07843121
First seen Sep 25, 2026 · Last updated Sep 25, 2026
Summary
Researchers at the University of Extremadura are testing a 14-week supervised exercise program for women recently diagnosed with breast cancer who are receiving adjuvant treatment such as chemotherapy, radiotherapy, or hormone therapy. Sixteen women take part in twice-weekly one-hour sessions that combine aerobic exercise, strength training, joint mobility, flexibility, and relaxation techniques, plus one hour of independent activity each week. The program is built around Self-Determination Theory, which aims to support participants' sense of autonomy, competence, and connection. The study measures changes in psychological needs, exercise motivation, self-esteem, quality of life, and physical fitness before and after the program.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a supervised, individualized exercise program combining aerobic exercise, strength training, mobility, flexibility, and relaxation techniques
- What this could lead to
- If it works, this could point toward structured exercise programs that help women in breast cancer treatment feel stronger and more motivated to stay active.
- What could go wrong
- This is a small pilot study with 16 women and no comparison group, so any changes seen may not be due to the exercise program or may not apply to other patients. Exercise during cancer treatment can also carry risks for people with heart conditions or severe physical limitations.
