Participants will be grouped based on their previous cancer treatment: hormonal therapy only or hormonal therapy combined with chemotherapy. Functional performance will be evaluated through the 6-Minute Walk Test, 30-Second Sit-to-Stand Test, and a submaximal treadmill test. The study will analyze differences in muscle oxygenation and performance between groups and explore associations with other functional and clinical parameters.",[24,25,26,27,28,29,30],"Breast Cancer Survivorship","Muscle Oxygenation","Near-infrared Spectroscopy","Exercise","Quality of Life","Functional Capacity","Hormonal Therapy","NOT_YET_RECRUITING","2025-05-13",{"date":34,"type":35},"2025-05-16","ACTUAL",{"date":37,"type":20},"2025-05-05",{"date":39,"type":20},"2025-05-31",{"name":41,"class":42},"University of Extremadura","OTHER",""]
