Exercise regimens after breast cancer treatment for muscle growth and conditioning

EXERT-BCHC: Prospective Study of EXErcise Regimens After Treatment for Breast Cancer for Hypertrophy and Conditioning

Observational Allegheny Singer Research Institute (also known as Allegheny Health Network Research Institute) · NCT07023887

This study tests four supervised resistance-training programs to see which best improves fitness and muscle mass in women who have completed breast cancer treatment.

What this trial studies

This prospective observational study compares two conditioning regimens (6-12-25 and 8x8) and two hypertrophy regimens (5/5/5 cluster sets and double training) in women previously treated for breast cancer. Participants will join monitored group resistance-training sessions and undergo measurements of VO2 max, muscle mass, and fat mass to track changes over time. Women receiving active cytotoxic chemotherapy are excluded, and participants must have at least six months of resistance training experience under a Certified Strength and Conditioning Specialist. The primary aim is to determine how different standard-of-care resistance protocols affect conditioning and hypertrophy outcomes.

Who should consider this trial

Good fit: Women aged 20–89 with biopsy-proven DCIS or invasive breast cancer who have completed treatment (not on active cytotoxic chemotherapy), have been prescribed exercise as standard of care, and have ≥6 months supervised resistance-training experience are ideal candidates.

Not a fit: Patients on active cytotoxic chemotherapy, those unable to safely perform group resistance training due to severe cardiovascular, musculoskeletal, or joint conditions, men, and pregnant women are unlikely to benefit from or be eligible for this protocol.

Why it matters

Potential benefit: If successful, the results could identify resistance programs that improve cardiorespiratory fitness and increase muscle mass for breast cancer survivors.

How similar studies have performed: Exercise programs have previously improved fitness and quality of life in breast cancer survivors, but direct head-to-head comparisons of these specific resistance regimens for hypertrophy versus conditioning are limited.
