Muscle Oxygen Saturation and Functional Capacity in Breast Cancer Survivors
Sponsor: University of Extremadura
Summary
This cross-sectional observational study aims to assess muscle oxygen saturation (SmO2) in the intercostal, quadriceps, and triceps surae muscles using near-infrared spectroscopy (NIRS) during functional exercise tests in breast cancer survivors. 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.

Functional Exercise Testing and Muscle Oxygen Saturation Measurement
Participants will complete three physical performance tests: (1) the 6-Minute Walk Test (6MWT), (2) the 30-Second Sit-to-Stand Test, and (3) a submaximal treadmill test. Muscle oxygen saturation (SmO2) will be continuously monitored during the tests using near-infrared spectroscopy (NIRS) devices placed on the intercostal, quadriceps, and triceps surae muscles. Additional variables such as heart rate, perceived exertion, respiratory pressures, pulmonary function, and fatigue will be assessed during or after the tests.
