Supervised clinic resistance plus relaxation versus home resistance exercise to improve life after breast cancer

Long-term Evaluation of the Body Composition and the Impact of Resistance and Relaxation Exercise on Muscle Mass and Quality of Life in Patients With Breast Cancer

Not applicable Interventional Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation · NCT07465393

This trial tests whether a supervised clinic program combining elastic-band resistance exercise and progressive muscle relaxation helps post-treatment breast cancer survivors more than a self-guided home resistance program.

What this trial studies

Post-treatment breast cancer survivors are randomized to a 16-week, twice-weekly program of either therapist-led elastic-band resistance exercise combined with progressive muscle relaxation delivered in a facility, or a self-directed home-based elastic-band resistance program. The facility arm is supervised by therapists and integrates relaxation techniques intended to address psychological and neuromuscular tension from cancer therapy. Outcomes include changes in muscle mass, physical performance, and quality of life measured before and after the 16-week intervention. The trial focuses on adults with stage I–III breast cancer who have completed adjuvant chemotherapy, comparing multimodal supervised care with isolated home resistance training.

Who should consider this trial

Good fit: Adults (≥18) with histologically confirmed stage I–III breast cancer who have completed adjuvant chemotherapy (with or without radiotherapy), can follow the protocol, and are willing to attend facility-based training are ideal candidates.

Not a fit: Patients with metastatic (stage IV) disease, morbid obesity (BMI >40), uncontrolled hypertension, implantable medical devices or metallic implants that interfere with assessments, contraindications to resistance training, or those already doing intense systematic exercise are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, the supervised multimodal approach could yield greater gains in muscle mass, physical performance, and quality of life and potentially reduce treatment-related complications.

How similar studies have performed: Resistance training has previously improved muscle mass and quality of life in cancer survivors, but combining elastic-band resistance with progressive muscle relaxation is less tested and thus relatively novel.
