SUMMARY

This study, titled Evaluation of the effect of regular physical exercise in women with breast cancer on adjuvant hormone therapy, is a research project designed to see how guided exercise can help women recovering from breast cancer. Here is a simple summary of the study: Who is it for? The study includes 150 women who have finished their primary treatments (like surgery or chemotherapy) and are in the early stages of hormone therapy. The Goal: Researchers want to understand how regular exercise improves quality of life, physical fitness, and nutrition. They are also studying how exercise affects the immune system and the gut microbiota (the healthy bacteria in your body). The Exercise Program: Participants take part in a 16-week supervised program. It consists of two sessions per week: one in a gym and one in a swimming pool. These sessions are led by experts and are specifically adapted to each patient's physical condition and needs. Using Technology: To help with the study, participants use a mobile app (IALIBIRD) and a wearable activity tracker (like a bracelet). These tools monitor daily steps, sleep quality, and heart rate, and allow patients to report how they feel. Medical Check-ups: Throughout the study, patients have regular visits to the hospital for blood tests and to provide saliva and stool samples for biological analysis. They also have body scans (DXA) to measure bone health, muscle mass, and body fat. Why is this important? While hormone therapy is a vital treatment, it can last for 5 to 10 years and cause side effects like extreme tiredness, joint pain, and anxiety. This study aims to prove that regular exercise is a safe and effective way to reduce these symptoms and help women feel better during their recovery.

Experimental: Experimental
The experimental arm consists of a 16-week supervised exercise program for women with Stage I-III breast cancer receiving hormone therapy. Participants perform two weekly sessions (one gym, one pool) at the Dehesa Boyal Sports Center, led by specialists. The intervention progresses through four monthly phases: adaptation, base building, moderate progression, and consolidation. Intensity is tailored using the Borg Scale and heart rate monitors.~A central component is the IALIBIRD-CM digital platform, where patients use an app and wearables to track activity, sleep, and symptoms. Monitoring includes DXA scans for body composition and regular collection of blood, saliva, urine and stool samples. These help researchers analyze changes in the gut microbiota, immune markers, and genetics to understand how exercise improves quality of life and mitigates treatment side effects
