Breathing training may help breast cancer survivors get moving
NCT ID NCT05193149
First seen Jun 27, 2026 · Last updated Aug 18, 2026 · Updated 6 times
Summary
This study tests whether training the muscles you use to breathe can improve how long obese breast cancer survivors can exercise. Researchers will compare breathing exercises plus aerobic exercise to aerobic exercise alone in 78 women who finished treatment. The goal is to see if this helps them feel less tired and move more easily.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- inspiratory muscle training (breathing exercises) and supervised aerobic exercise
- What this could lead to
- If it works, this could offer a simple, drug-free way to help obese breast cancer survivors feel less tired and exercise more easily.
- What could go wrong
- This is a small, early-stage trial (78 people) looking at short-term changes in exercise time. The results may not apply to all survivors, and the training might not improve daily life.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * completed active treatment for a Stage 0-III breast cancer diagnosis within 6 months to 5 years of enrollment. * obese as defined by a body mass index (BMI) of 30 to 50 kg/m2 * patients who are on adjuvant endocrine therapy will be allowed to participate. * sedentary (participating in less than 90 min of moderate intensity activity per week) and have at least one limitation in activity on the 10-question RAND-36 Physical Function Subscale to ensure some exercise intolerance Exclusion Criteria: * functional limitations that make independent exercise unsafe * metastatic breast cancer * ongoing or active infection with recent antibiotics or steroids * Bilateral Axillary lymph node dissection (ALND) of \>5 lymph nodes on each side, which could increase risk of lymphadenopathy with repeated blood pressure measurements during exercise or if patient has been advised by their clinician to avoid repeated BP measures on both arms. Bilateral Sentinel Lymph Node Biopsy (SLNB) will be allowed. * heart disease precluding exercise (congestive heart failure, unstable angina pectoris, cardiac arrhythmia) * psychiatric illness/social situations that would limit compliance with study requirements * orthopedic or neuromuscular disorders or arthritis that preclude participation in exercise * unwilling or unable to follow protocol requirements * pregnant or nursing * any condition which in the investigator's opinion deems the subject an unsuitable candidate to participate in this study * presence of provokable ECG changes suggestive of heart disease, or dangerous arrhythmias or exercise induced hypertension, etc. during the cardiopulmonary exercise test * non-English speaking
