Developing a Comprehensive Exercise Service for Breast Cancer Process

"Moving Together" (Juntas en Movimiento) is a hospital-based, comprehensive, and personalized exercise service designed for women diagnosed with breast cancer. This implementation study aims to evaluate the feasibility, safety, and impact of integrating a free, tailored exercise program into routine clinical care at Hospital Clínico San Carlos in Madrid, Spain. The program offers multiple participation options-supervised in-person, supervised online, autonomous at home, or autonomous at a fitness center-allowing patients to choose based on their preferences, limitations, and treatment phase (pre-surgery, during chemotherapy/radiotherapy, or survivorship). All exercise options are adapted to individual needs and include aerobic and resistance training components. The study uses a real-world implementation science approach, guided by the Consolidated Framework for Implementation Research (CFIR), to assess clinical, physical, and psychological outcomes such as quality of life, cardiorespiratory fitness, muscle strength, body composition, and adherence to physical activity. Data are collected through clinical records, physical assessments, validated questionnaires, and wearable technology. This pioneering initiative in Spain seeks to establish exercise as a standard complementary therapy in oncology care, bridging the gap between scientific evidence and clinical practice, and promoting long-term health and well-being in breast cancer patients.
