Exercise may boost metabolism in aggressive breast cancer patients
NCT ID NCT07484776
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how well the body of women with early triple-negative breast cancer can switch between burning fat and sugar for energy—a trait called metabolic flexibility. Researchers will test if different types of exercise (moderate cardio, high-intensity cardio, or strength training) can improve this flexibility, muscle strength, body composition, and quality of life. Forty women will be tracked from diagnosis through treatment and a 12-week exercise program.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- exercise training (cardiovascular at FATmax, cardiovascular at MAP, or resistance training)
- What this could lead to
- If successful, this could show that specific exercise programs improve metabolic flexibility, strength, and quality of life for TNBC patients.
- What could go wrong
- This is a small, early-phase study with only 40 participants. Results may not apply to all patients, and exercise benefits may be modest or not sustained.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria: * Female between 20-55 years of age. * Confirmed histological new diagnosis of stage I to III triple-negative breast cancer and a candidate to receive systemic neoadjuvant treatment with chemotherapy +/- immunotherapy. * Must not have started systemic treatment for the neoplastic disease. * Participating in any external physical exercise program or sports activities during the experimental study phase. * Inability to understand and provide written Informed Consent (IC) Exclusion Criteria: * Having neurological or orthopedic disease at the time of recruitment or during the study evaluation and intervention. * Inability to understand Spanish language. * Presenting absolute contraindications for performing a cardiopulmonary exercise test (CPET) such as heart failure, myocarditis, acute pericarditis, severe aortic stenosis, aortic dissection, vascular toxicity, uncontrolled severe arterial hypertension, uncontrolled severe cardiac arrhythmias, pulmonary thromboembolism, or severe anemia. * Have relative contraindications for performing a CPET such as bradyarrhythmias or tachyarrhythmias, moderate valvular stenosis, inability to perform physical or mental exertion, chronic infectious diseases, musculoskeletal disabilities, ventricular aneurysm, second- or third-degree atrioventricular block, or severe arterial hypertension.
